procat diff

[Drewwiley]

im just cheking really i have just assembled front and rear diffs. on the front when i rotate the front right wheel forward the left front wheel goes backwards, i know this is correct but on the rear diff i move the right wheel forward and the left wheel also goes forward. the rear diff isnt too tight but should the left rotate opposite like the front.

thanks

Yes, the rear diff should do the same. If you hold the spur gear, regardless weather the diff is a bit tight or not the wheels should rotate in opposite directions when turning one.

umm the only thing i can think ofis that i used used hex washers rather than friction paper. if it is not that any ideas

Shouldn't make any difference. If the diff is a bit tight you will need to hold the spur, otherwise you'll just turn the entire drive train rather than see the diff action. If you've no motor fitted to provide some resistance in the drivetrain, I'd expect the whole lot to turn anyway.

no motor fitted, if they should run opposites ill have to take apart i guess.
anyother suggestions

Post some pictures of it when apart just so we can see if all the correct parts are there
