You would have not needed the lovejoy coupler, pillow block bearings, or shaft. All you would of have to do is weld the sprocket to the coupler and drill the shaft and tap it. Then slide on the coupler and put the bolt in the center and tighten it down.
Maybeso....but this has been fun. A challenge. And maybe something to cuss on down the road. I'm out ~40.00 for the parts, and that's if I replace 'em. Had the pillow blocks on the shelf gathering dust. Well, their boxes were gathering dust. The jaw coupler was <20 on Amazon for both halves and the spider. Everywhere I looked for that adapter thing, it was >75 and those were out of stock on the lower end of prices. So.... no biggie.... kinda a wash in the dollar department and it was a fun squirrel to chase.
Today saw me get the chains cut and laid out. Like I said before, got to start from the axle since it's the only thing with a non-negotiable location relative to the rest of the drive train. From there I went forward and settled on a place for the FnR box and got its mounts tacked into place and built a push post for the tensioner. All tacked on, no stick burning just yet. Then laid in the front chain and made sure it had room to take up slack with the engine slide. The order of chain tensioning is to get the back chain right and locked down, then slide the engine to get the front chain in the right place. As they wear in, it'll have to be done in that order again, probably after a little bit of use, maybe down to the mailbox and back. Jacked it up and rolled the drive tire with it in Forward, and chains all looked like they're running centered on their sprockets, so must be pretty close with the alignment.
I then took everything off the mounting frame and pulled it out and took it to the work bench and welded stuff the rest of the way. A little here and a little there, added another piece or two of reinforcement in places too. I don't think I got any one area hot enough to warp anything, it was still sitting flat with no rocking whatsoever on the piece of plate I had on the workbench, and I did swap ends with it and set it on there sideways, sat solid every way I'd turn it.
So it got moved over to the paint rack (a/k/a the little sheet metal garden tractor wagon
) and got a slathering of Ospho. Tomorrow it'll get some black enamel on it and depending on the sun and so forth, I'll either put it back together tomorrow or Monday, and start in on tying all the controls together. I do need to stand the buggy up like a deer ready for dressing and figure out how I'm going to use the existing foot feed on the Predator's throttle....and find a routing to get the choke cable and kill switch up on the dash board. Also going to see if there's some way to route the pull rope up to the dashboard too, maybe using EMT and some 550 paracord to make a (really, REALLY) long pull start on it. Hey, if they can move the pull rope halfway up a lawnmower's handle, I ought to be able to move it to the dashboard!
Not even ordered yet are the new exhaust pipe and air cleaner adapter. I need to get out there some evening with Amazon and eBay pulled up on my phone and, at least on the intake side, see if something looks like it's gonna fit. Exhaust side, I'm not terribly worried about just yet. Maybe it's misplaced confidence, but I'm pretty sure I can make SOMETHING work that won't have me selling my first born into servitude.
Pics all at the end today, what few I remembered to stop and take. Was kinda frustrated with my phone--something cut loose in it and it just starts doing silly stuff all on its own until I slap it around a few times and put it to sleep for a few minutes, and when I do that and go back to work I forget to take the pics before I get past the point I wanted pics of. Aside from all that, I'm whupped and it's late. Didn't even bother snapping a pic of supper, nor of Peewee drooling at it.
