No Go For Joe

Chack the lay shaft gears make sure the grub screws are tight. You might have to lift it up running then set it down under power and maybe the drivetrain that is not right will make a noise or give you something to go on. We covered most of the usual remedies here. The pinion gear on the clutche bell still has its flat in it to catch the shaft doesn't it. it being the stoc plastic one maybe it has spun inside and now has no flat to catch. Keep posting the symptoms we will get it figured out.

have you pulled the spur gear...the hole looks rounded out where it mounts to the layshaft in the picture...maybe it's spinning on the layshaft also are all your dogbone pins there..

OK just pulled the pinion on the clutch bell and spur. All good. The pinion on the lay shaft is tight as a drum. I cant get the allen screws out but tried to move it with plyers its going no where. The symptoms are fires up perfect. Go to give it throttle and it bairly moves go for moe throttle and just whines. I see the pinion and spur moving the layshat gears just fine but no go

so is it turning the diff as well?

 

[magnum57]

It tries to to turn it. I set the truck on the ground and give it gas and its just tries and then nothing. Its like the diff is not working but I know its fine. Well I think its fine. CRAP

Are the dif gears spinning? I put mine up on a paintcan and spun the main gear (clutch bell)(with everything opened up) to see where the spinning stopped....it was my dogbone cup shaft.

Maybe we are looking at diff when we should be looking at motor check the clutch bolt that holds the clutch holder to the crank it is a drift fit only no key if it is loose would cause symptom you describe.

 

[mooman007uk]

thats a good point they're just a taper fit


does the duratrax diff have the splined cup or a pin? maybe the pins broke.


Did you check all the dogbone pins

 

[magnum57]

My diff is apart now I put the diff cups in and turn one side and spins fine same on the other side. If I hold the diff and try to spin both diff cups at the same time it wont spin it moves the whole diff housing like it should. It looks like its fine. I think a few more beers and I'll figure it out Its like dam its something simple and I cant figure it out

 

[mooman007uk]

check the wheel squares...if ones rounded out in the wheel you go no where or maybe a square is loose on the axle

 

[magnum57]

Son of a Bi%*# I've got one wheel that has a round hub. WOW mooman007uk this could be my whole problem. I'm going to put on one of my FG tires and check it out. I will owe you one if this is it. Too simple.
