I installed a new 18mph clutch set on my 2000 6x4 diesel, it seems that I have lost some umph on the hills, sure it zooms on the flats but it is steep where I live and half the time I find myself...

forgot to add Its a 2000 model 6x4,,, My concern is that when the motor is revving up and the gator is moving there is a period of time in the belt and clutches travel where the belt is loose enough...

My diesel gator really torques the engine towards the tranny when revved up. is there suppose to be a spreader bar that keeps that from happening? all the motor mounts are fine

Well it is and came off fine with a little extra grunt

Old thread but I wired my fan to a wire that is hot when the switch is on, stays on all the time when the engine is running, mine had the same issues as yours

Can this be done with our secondary clutch?? I have found a video about setting a secondary clutch like ours on a snowmobile to increase spring pressure and adjust shifts, I live where it is steep...

Once the clutch engages at all the noise goes away, only at idle does it make the rattling sound. And it is for sure the primary clutch, the one mounted on the engine crankshaft.

The bolt holding the secondary clutch on,,, it is a standard counter clockwise to loosen bolt is it not??? Mine seems awfully tight and I want to be sure before taking it on again.

I just installed a new AM138487 primary clutch on my 2000 6x4 diesel gator,, it seems to work well, gator shifts easy now. The old clutch was sticking, turns out the plastic parts had broken off on...

This is the only thing I have left to do to my new to me 2000 6x4 diesel,, new 3tn68 motor is in, everything hooked up but this hose, have the new gator water pump installed, have the T shaped...

I'll get some the next day or 2 ,,, all done now except the upper radiator line

switched the motor mounts, oil pan and oil pickup, have to get a new gator water pump and should be good to go

oh ya had to switch the exaust manifold as well, intake will work just fine

Well I got the 68 motor, looks like it should be a pretty easy fit

well the water pump looks the same so no problem with the coolant lines, the throttle cable will need to be re-angled but my existing brackets should handle that, air intake looks the same from the...

I cant be the only one that has replaced a whole gator diesel motor? The 3TN66 in mine has 3 shot pistons and a ruined head, It could be cheaper to replace the whole motor,,, have found a 3TN66...

I'll get some images, right now it is a really clean 6x4 gator on jack stands without a motor,,,,

Hello all, I just bought a used gator that has a bad motor. The 3TN66 that is in it has a badly cracked head and 3 ruined pistons, the block and the rest of the motor seem fine, and the rest of the...
