[Complete] John Deere 110 "Sub-Compact Tractor" Build [2018 Build-Off Entry]

Yeah I'd have a machine shop do it or get a dremel tool or something, it'd really suck to mess it up.

Yeah, pull the crank out and have a shop put one in with a 3/16" end mill, a lot better off that way.

Yeah man, if you do it right you won't regret it later.

Uh, we're talking about the engine going into the tractor you're building in this thread, I don't see how that's thread jacking. Also, we're just trying to help you out here..

We're still talking about this tractor, not some other random stuff.

So are you gonna do it right or mickey mouse it?

I know but ya'll have reiterated yourselves many a time. I get your points, okay?

This is what he's going to do with it   

you know, if you took a dremel and stacked a few cut off wheels together you cold probboly cut a decent key way, wold make test it on some junk shaft or something Chinese first.

That's a good idea.  Practice on some scrap metal.  You could grind the keyway close like he suggests and then take your time filing it to perfection.


There is a way to do this since you already have a straight section of crankshaft to work with:
1)get the pulley hub where it needs to be
2) with the setscrews removed mark their locations on the crankshaft
3) spot drill a couple of dimples for the setscrews to dig down into.

The key thing here is to make sure you have the hub location correct the first time because it's not going to be as easy to move it.

W, I would try to get a free blown Generator, and cut off the generator the tapered end, and try if it fits your Diesel tapered shaft and if it fits, weld the pulley on the tapered part of the generator, and cut off the generator crap you do'nt need

i wold be worreid about heat from welding warping the shaft. id personally cut my own keyway, plus what if he decides he wants to change is pully size later? always gotta leave room for change!

Machining the tapered shaft end to 1" and cut a keyway in there, so it should be the best solution in my eyes

100% agreed, but unless you have the tools or know a guy its easier said than done.

posting this becase i think Double W Cross Ranch wold find this craigslist post interesting
its out of my price range but looks quite similar to his john deere even though its a slightly different model.

Possibly, but I don't own a dremel.

That was my backup plan.

Unfortunately, that won't work as the pulley needs to be pretty far up the shaft to be aligned.

Yeah, cuz I might change the gearing of it.

Yeah but I'd have to pull the whole shaft out and take it to a machine shop to do that.

I have neither.

That's super cool. A little overpriced for what it is in my opinion.

i used 2 of thoes disk stack together to cut the slit for the E clip in my axle shaft.

Just stay awake from Chicago electric dremmals from harbor freight, they are complete junk, but the accessories aren't too bad though

Paint time!  @AllisKidD21 Yes I bought a more accurate JD green, lol.





I think that the grille looks better yellow although it was black stock.

Here's the notorious crankshaft.

And here are the fenders, sitting outside in the rain.  Didn't get to them today because they are wet.
Lemme know what you think!

AWWW, that yellow on the grill looks slick, maby you can sneek some yellow on other small parts?

HAHA...

I would have probably painted like a patio series deer.  Those are so cool!

Yeah those Patio Series are pretty neat, really rare though.

I'm not sure what you mean @RockeyDA?  Did you mean the grille?  I plan to paint the pedal, the rims, the vari-drive handle, the engine pulley, etc. yellow.  Should look cool.

Hmm...not my style really.  Anyway, I like the classic John Deere look.

Yeah, I'd never seen them before.
