A833 Rebuild

Trying to put this back together and the main shaft will not go into the input shaft after multiple tries. The pins (?) under the slider gear fall out or the gears/slider gear keep it from going in straight.The stop gear (syncro?) is on the input shaft. Are the any tricks to doing this? The only difference I see from the shop manual is that the case is vertical rather than horizontal when we are trying to do the install.




Thanks,
Larry

 

I've never built a stick trans. that didn't benefit from having the slider in neutral between the input and the frontmost gear on the mainshaft. I'm not familiar with the "pins" or keys / struts on your box specifically but I'm used to blocker rings notched for clearance for them; can't see that on yours?

 

We usually used some heavy grease to hold the needle bearings and other small pieces in place on the transmissions I've done.

Have you checked this link/ http://www.moparmusclemagazine.com/...ding_the_a_833_four_speed_tranny/viewall.html

It has some straightforward info that might help.

 

i always install the input on the output shaft assembly on the bench without the front bearing-then install the assembly in the case --then install the front bearing and snap ring last----hope this helps -dave

 

Me too on the assembly. I was thinking about a stray needle bearing.

 

Thanks for the advice. One of the pieces(3 total) that fall out is missing in the first photo. The slider gear is marked where the notches are in the synchro ring.

We may need to put the input shaft on first but the mopar article shows it already in.

Most of the time we don't get far enough to knock the bearings out...

There should be enough tension on the syncro struts (the 3 small rectangular pieces) to hold the slider in the neutral position without it falling out. Are you sure you have the strut springs in right? The bend on the end of each of the 2 springs should lock into 2 of the struts.
Maybe the slider is off one tooth? The bumps on the struts should fit into the notches ground into the inside of the slider. You should be able to feel a definite detent as the slider moves from one side of the hub to the other.

 

Thanks for correcting me on the syncro strut. We got it today by taking the retaining spring off of the input shaft and dropping the shaft down (mounted vertically). At least that's how I think it happened.

Thanks,
Larry
