The installation kit I used is very simple, but cheap. A real proper installation uses a device not dissimilar to a pop rivet gun, but this one uses a cap screw threaded into the nut and retained by a spacer you can hold with a wrench.
The Paintman Cometh
We spent much of Sunday shopping for stuff more or less directly connected with painting the soon to be formerly white trike.
The right fender was slightly damaged in what is reported to be an accelerator mishap. It had been pounded back into shape reasonably well, but we wanted to replace it before painting. that sort of thing always shows through.
Northern Tool had fenders that were pretty close, so we got two so we can replace both to match. As a bonus, there is probably enough good fender on both of the old ones to redo the fenders on Sponge Bob.
It looks like the old fenders on the trike were previously on another trike and the mounts on the trike look like they were originally made for other fenders. [This is the fourth version of that sentence, and I still don’t like it]
I started with the banged up fender.
The new fenders are slightly smaller, so I removed a bracket “extender” of sorts (just visible at the rear of the fender above) and it looks like the original brackets will fit them. I then measured and cut a notch in the front of the fender to clear the mount. Once the notch fit well, I marked the back of the fender and cut that notch. That fender appears to fit perfectly. Then I repeated for the other fender. Somehow, I manged to avoid photographing the new fenders.
Bit O’ Tinkerin’
I versed the turn signals on the white trike… re-reversed, I guess. I figure two re’s make a null, so “versed”. In any case, they work as expected now… 🙂
One of the troubles with this trike is the sloppiness of the shifter. It’s a fairly short linkage, but when we got it, there was obvious movement in every single piece. The shifter itself was sloppy and missing the tension spring. The shifter box is only bolted on the front end, leaving the back end able to lift and move, especially when shifting to 1st or 3rd. The shaft had been spliced with a piece of 1/2″ EMT with a single 1/4″ bolt through each half, and those were lose. The coupler to the transaxle is a little worn. I presume the hockey stick bushing is sloppy, though I haven’t specifically investigated that.
Really, improving any one of these areas would be enough to help, and indeed, just tightening the two 1/4″ bolts splicing the shaft together helped. Installing a new standard Empi shifter and greasing the internals in the shift box helped even more, and restored proper reverse lockout operation.
There was an unused, or perhaps more precisely, abandoned, bolt hole in one corner of the shifter box. It went through the top of the box, the bottom of the box, the deck and through the 2″ square tubing beneath that. The very bottom hole and the rest of the holes did not quite line up, but by the simple expedient of putting a slight bend in the bottom 1″ or so of a piece of all thread, I was able to fish it through. I cut it to length and tightened down. It eliminated all but the slightest detectible movement of the shifter box and shifting improved about 10 times.
In exercising it, however, I noticed it was much stiffer shifting into 2nd, 4th and reverse that to 1st and 3rd. Watching that action while running through the gears revealed that the short end of the shaft flexes enough when going to the even gears that it puts the shaft in a bind within the bushing at the rear of the shift box. I found that I could loosen the new bolt and actually improve operation minimally. What turned out to work better was lubricate the bushing. I couldn’t find my grease gun, so I used silicone spray for the short term and it served as the miracle cure.
The real solution will be to stabilize the shaft then maybe to adjust the height of the shifter box and/or the bushing if needed.
I think I can take this shaft out and either weld it into one piece or replace it with a newly fabricated one and eliminate almost all these issues.
The last thing I did was cut a new gasket for the front brake master cylinder. It apparently drips when underway, resulting in brake fluid drops on the right shoulder. Maybe good for street cred, but little else. For the ride home last night, we just tied a rag around it. 🙂
Puff Shifter
Since Gabby took the white trike to work tonight, I reworked the shifter on Puff.
The first thing I did was shop for a ratchet U-joint with the least play in it. I chose a spark plug socket with a built in U-joint. here it is compared to the previous joint for the transaxle end.
First, I cut the end off the other joint. It is part of an adjuster, so it is the proper size for the coupler and includes a set screw dimple. I also cut the end of the socket off so that when the end is bottomed into it, it is the minimum length. This should make the entire assembly shorter with less side loading when shifting.
I clamped it up…
And welded it together.
I then cold forged the the end of the tube to fit the drive end of the socket and welded that. There is the completed joint.
I test fit the shaft to get an idea where I would have to move the shifter.
Next came the tougher bit. I repositioned the Super Shifter so that the new shaft can be used with it’s single U-joint. First, I cut off my ever-so-carefully placed shifter mount, then cut the rear bracket shorter, while hand fitting the shifter. Once I was “happy” with the placement, I used a jack to hold it at the right height, a drill bit under the box to hold it at the correct angle to the ground and a C-clamp to clamp it to the shaft for the proper angle to the transaxle.
Sorry about the odd angle. I was trying to eliminate shadows and reflections off the chrome box. I ended up leaning so far over that it’s like I held the camera upside down.
Anyway, made those two welds and I really hope the fiberglass body still matches up correctly.
All that remained was to cut the shaft to length and to grind the end down to fit in the coupler.
I have used a drill bit as a temporary pin, but here’s the completed shifter.
Compare the angle with the previous attempt:
This layout works MUCH better. It works so well that I foresee speedshifts.
A Thousand Points of Light
Ok, maybe not a thousand…
Gabby was running late enough that she didn’t take the white trike to work on Tuesday night, so I put the handlebar switch on and wired it up.
Because the new headlight has a halogen bulb and I wanted to put the auxiliary light on with the high beam, I used a relay to power the headlights rather than smoke the old motorcycle switch. Fused power is on the common (30) and one side of the coil (85), low beam on the normally closed (87a) and high beam/auxiliary on the normally open (87). The high beam position of the switch grounds the other side of the relay coil (86)
I also connected the horn button and the turn signals. I did not, however, test the signals and managed to reverse them! Left switch signals for a right turn and vice versa. It’s taped and tied down well enough that I didn’t want to tear it open to swap them. I ran out of time, but I should have it again Thursday night and I’ll swap them back to normal then.
A Little Light Drama
No light is dramatic at night.
After the BTW meeting, Gabby rode the white thing to work, with me and Sponge Bob in escort. There were no (known) problems. When she got off work that night, she had no main headlight and the smaller “high beam” was dim and/or flickering. I did some quick field testing and decided that the bulb must have gone, as new stuff is sometimes likely to do. We used some wire ties and spit to get the smaller light to stay on and rode on home.
This evening, I chased down the troubles, and there were indeed two independent failures. Some NASA engineer is getting fired for this…
First, the main headlight, the new one. I’m the engineer getting canned for that one. I used a self-soldering heat shrink type of connector and maybe I didn’t heat it enough or something. It didn’t bond well and with it sinking current for two halogen filaments simultaneously, it heated up and came unsoldered. Ground open, no light.
The smaller high beam thing had a similar problem, but this one wasn’t my fault. This light was operated by a small rocker switch mounted on a bracket on the left mirror bracket. Neither the wire nor the solder point on the rocker switch was adequate to power that light. One of the wires had come unsoldered from a switch terminal. The wire can’t be any bigger than 20ga and the switch is probably good for 1A. For the short term, I connected the lead from the light directly to power in it’s harness.
So, the white thing’s headlights are semi-permanently wired to the keyswitch.
I have begun refurbishing the handle bar switches (and throttle) from a Suzuki something or other than the previous owner of Puff threw in. They fit one inch bars. I wire brushed all the paint and corrosion off the left one and painted it. I decoded the wiring and I will be ready to install it one evening this week. It will cover hi/lo, turn and horn. The right hand switch has a run/stop switch and a start button. Just this moment, those functions are covered elsewhere, but I’ll still be interested in using them.
Tinker gave me a couple of screws for the cooling tins. I applied them both the cylinder tins. The 1-2 cylinder tin didn’t have any screws at all. Neither did the doghouse.
Then I noticed a bigger problem. The righthand fuel tank bracket either lost it’s bolt or never had one. There is a welded-on 3/8″ nut on the frame bracket it bolts to and it had a lot of rust inside.
Anyway, I found 5/16″ bolt and nut, manhandled the full 8 gallon tank into position and bolted it down. Someday, I will replace the 1/4″ x 1″ flat straps with 1″ angle or maybe 1″ square tubing. Either would be way more rigid and better suited to holding up 48 pounds of gasoline.
The As-Yet-Unamed White Trike
I apologize in advance for not taking many pictures of the work on the white trike. We were kinda rushing to get it on the road so Gabby could take it to our BTW local chapter meeting on Sunday.
The white trike was pretty much in ready-to-inspect condition, other than a silent horn.
Friday after work, I made a couple of stops and got some things I would need to put an obnoxiously loud horn on it.
The existing horn did have power to it, but not even a peep would emanate. I ran a wire from the old horn to a relay in the engine compartment. I mounted the horn by the battery and connected it to the battery, through the relay and a fuse. Of course, the positive battery terminal was corroded, making it difficult to connect to and the rubber battery tie down crumbled in my hands, so I went to the ubiquitous Autozone. I replaced the battery terminals, which involved cutting the charging lead from the generator since it’s bolt on the old battery terminal was inaccessible without a time machine. When I went to put a new connector on the charging lead, the corrosion had leached up the line, preventing it from taking solder. I elected to replace the wire, which was a good idea because it turned out to have a splice in it.
All that is fixed up and man, that thing is loud
For following is the very short version because it’s 2:30AM and I am having trouble forming complete.
See, I told you… I am editing this early Sunday evening, and I’m leaving the previous line there because that’s exactly how I wrote it at 2:30AM.
Saturday, we went shopping for parts, most notably a vacuum advance distributor to banish the famous flat spot. We did a little more parts shopping and went home. The inspection of the trike went without issue, then we started into the stuff we’d bought for it.
I forgot to take pictures for most of it… :/
I did take a picture of the first post-purchase bling to go on, a fuel pump blanking plate.
You might expect most anything *except* a fuel pump blanking plate installation story to include a bit of excitement. pshaw…
The trike runs with an electric fuel pump, and flushed with the relative success of my previous fuel pump blanking plate installation, I was keen to get on with it.
In the back of my mind, I think I noticed that the existing mechanical fuel pump looked kind of new and the previous owner reported that they had installed an electric fuel pump. When I tried to put in my blanking plate, I discovered why.
An aircooled VW engine fuel pump is operated by a pushrod that is rides an eccentric on the distributor drive shaft. Older, generator equipped engines use a pushrod that is about 4.5 inches long. Less old (factory) alternator equipped engines used a shorter fuel pump to clear the larger alternator, and thus had a shorter 4 inch pushrod. The smaller pump will work on either engine, so long as you have the shorter push rod. From the various auto parts stores, the smaller pump is just about universally stocked, but ya gotta use that shorter pushrod. This engine had the longer pushrod.
I’m sure the first time the installer cranked the engine, it was either very exciting or all they knew is that the engine still didn’t run.
For my part, it took a lot of pulling and tugging and twisting to get the bent rod out. Then the plastic heat insulator thing was broken. There is a piece of it still firmly attached at the bottom of the hole, though now it is nicely covered with a shiny new blanking plate.
Installed the distributor.
Just setting the basic timing might have gone a long way with the old one, but it runs WAY better now. Incidentally, the old distributor had a Pertronix electronic ignition module in it. I toyed with moving it to the new distributor and I am still interested in doing that, though I want to make sure I can just pull the sensor disk off.
I did *not* install new pulleys because the generator pulley was pretty well stuck and it looks like the crankshaft pulley is there to stay, too, since someone freakin’ welded it on….
In case you’re wondering, ya don’t do that. And, just in case you somehow think you need to… say, you live in a post apocolyptic desert and maybe large bolts are scarce…. a couple of tacks or stitches would be more than enough to hold the pulley on until the horn sounds… You don’t need a continuous bead.
Sadly, my heroic efforts to remove the pulley before I discovered this little tidbit bent the pulley. I again owe a debt of gratitude to the inventor of the deadblow hammer. May his lead shot ever flow.
There was a long list of things done to it Saturday evening, such as adjusting the seat, changing out the shifter (one of three steps needed to make it shift nicely), cleaning the air filter (think I saw Cuban Holy pollen in there), quick and dirty painting of the bonked fender, screws and TyWraps to minimize rattling, lots and lots of polishing, cleaning, buffing and namecalling.
After staying up so late Saturday night, we got up early Sunday morning and moved the brake and clutch pedals off the kind of strange pods they were mounted on. Time did not allow me to reroute the foot throttle cable, so the one for the brake is still physically there, but that will go soon.
The trike made it to the meeting without incident and was well received and Gabby took it on to work. I am about to go meet her for the ride home…
New Horse in the Barn
Sponge Bob Fender Trauma
As I was leaving work one day this week, I noticed at the right fender on Sponge Bob, which has always been pretty iffy, had come loose again, loose enough to rattle while the engine was warming up. I mentally added securing it, again, to my todo list.
I headed on home. The rattle was noticeable, but I didn’t pay much attention to it until I suddenly heard the fairly specific sound of metal on tire, a clunk, then no more rattling, just as I was traversing a railroad crossing.
I looked down and saw basically this:
Of course, I was moving at the time…
I turned around in a parking lot to got back and retrieve the fender.
It’s a big yellow fender, you’d think it would be easy to see. While I was turning around, a commuter train came through. Even though it took me a little bit to get turned around, I wouldn’t have thought anyone would have time to have stopped and pick it up, even stopping for the train. I couldn’t find it anywhere.
Then, during one of the turns I made, I saw something out of the corner of my eye.
The fender was still attached by one bolt, but had swung around forward and I just couldn’t see it with my helmet on!
I laughed heartily and just held it up by me for the rest of the drive home, which was only about a mile.
Shift linkage
I used 1/2″ weldable tubing to make a shift linkage.
The shifter came with a coupler that I used on that end. I had to take down the diameter of the tubing just a little for it to fit.
There is a roll pin supplied to stake the rod to the coupler. I may decide to use a more easily removable pin for the final assembly.
I used 3/8″ ratchet U-joints for the linkage. On the shifter end, I formed the tubing into a square end to fit inside the U-joint. I ground the face of the socket down to provide more surface area and to remove the chrome plating and welded it in place. On the male ends of the U-joint, I ground the tenon down to approximately cylindrical to fit inside the tubing and welded there.
The joints have a little more play than I had hoped. If they introduce too much play, I will try to tighten them up. If that doesn’t work, I may need to start over with better U-joints.
On the transaxle end, I used a shift rod adjuster but modified it. I hot forged the threaded end into a 3/8″ square to fit into the ratchet U-joint, shown here before welding.
The results look pretty good to me…
Still left to do is a support brace/bearing to stabilize the rod between the shifter and the first U-joint. I think I will use an appropriately sized bronze sleeve attached to a brace attached to the frame, although I have considered using Nylon. I will probably need this brace to be adjustable, so I will probably need to weld a tab to the frame for the brace to bolt to.
