May 9th update: — Linn Motorcycles

Well, couple of things, just little details, did some work on the primary drive, and started on my upgraded generator test stand

Here’s the engine mainshaft with keyway pointed towards the transmission, so it’s easier to align up the engine belt pulley.

Put one of those new fangled lip seals on the mainshaft, you can just see it in the pic. Also, you’ll notice there’s no primary chain oiler protruding from the engine case, Wasn’t on the case when I bought it, and it’s not needed, so I left it off.

Had to add spacers to the rear inner primary cover to get clearance from the pulley to the tin cover. As you can see, not too much room there. I also had to be sure that the rear chain wasn’t going to rub either. Fine line there.

Here I’m aligning the clutch hub studs so that the disks will slide smoothly on the studs. I had several that were slightly crooked, and caused the plates to drag on them. I ususally check this before installing the hub on the bike, but forgot. I… — Here I’m aligning the clutch hub studs so that the disks will slide smoothly on the studs. I had several that were slightly crooked, and caused the plates to drag on them. I ususally check this before installing the hub on the bike, but forgot. It just takes a gentle tap or two to get the studs realigned so they move smoothly up and down the studs. What you see me pounding on is the stud installation tool. It’s hollow with a step in the hole so that the stud rides on the step and doesn’t touch the threads on the longer studs.

I’ve wanted to update my generator test jig for quite awhile, just decided to take some time to get it started. It’s a roll-around cart with a place to mount a generator so it can be driven by the electric motor within the cart. The test panel itself is a government surplus generator test fixture I picked up at a swap meet a couple of years ago. It has a volt meter, ammeter, a variable field resistance to adjust output, and a load bank to test generator power output.

Here it is in a preliminary form. When I have all the bugs worked out, (mounting positioning of motor/drive system/generator, I’ll redo it in some nice wood instead of OSB

The gear driving the generator is actually a “45” exhaust cam. When I first built the drive gear/pulley setup, 45 cams were a dime a dozen, especially to me ‘cause I don’t play with 45’s. Any way, everything seems to work out just fine, so one of … — The gear driving the generator is actually a “45” exhaust cam.

Any way, everything seems to work out just fine, so one of these days I’ll make it pretty :-)
