OK so I have an 89 TRX300 with some crazy rear end in it. I believe it is the rear end out of a samurai (yes the SUV) this is defiantly out of some kind of car or SUV. It has a diff cover and E-Brake lines and all. There is no back brakes hooked up but the wheel cylinders and all are still there. The rims are drilled out to make it fit and all. Anyone have any ideas on how to make this thing have brakes or any ideas on what the rear could have come out of? I don't know if this is a commonly known swap or anything but it is defiantly ******* engineering at its best. PIC's To come soon.

I know the rear end in the Fourtrax 300 was a bad design, but I've never seen a conversion like that. LOL. The only conversions I know of are the rear ends out of the 350 Foreman and the Big Red 3-wheeler. LOL.

I brought the camera but my friend didn't bring the quad to the shop. Going to have to wait till tomorrow. It isn't a bad job of a conversion the only problem with it is that where the swing arm is welded the rear is cast so what we are planning on doing is extending the swing arm and using U-bolts instead of welds so it will be removable as well as hold better. It actually works very well. It didn't seem to change the gear ratio very much but we had to take the front drive shaft out so it must be a little bit different.

That's the first one of those I've seen. LOL. I'll bet the diff will hold up on that.

Yeah I would hope so. The only problem with it is where it is connected but that will be solved soon when we extend the swing arm and use U bolts instead of the welds to cast that they have there now. Hey helmut I have a question for you about the valve seals on this thing. Like i said I am used to 2 strokes. Should i replace them it was smoking but the cylinder walls were marked up and the timing chain was stretched to much so that should be in in a day or so and the cylinder is already on after being bored and all.

I would go ahead and replace the valve stem seals since the timing chain was stretched and the cylinder had to be bored. They probably need to be changed too.
