I have two problems with my Tailhousing.

1. I can not seem to get a new mainshaft bushing to press in without it bending upwards into the oil galley a tad. This prevents the driveshaft from freely sliding in. It must be binding it up just enough. I have tried 3 time. Twice with my bench press and a third with a seal driver and hammer. I have tried both the stock replacement and the Rockland Standard Gear "long" version. Both do the same.

2. Does the reverse idler gear have two thrust washers on either side of it like the rebuild manual shows. Their is no room for even one. If I leave both off then the plate will bolt on. Are they required?

Any advice? It suxs to be this close to finishing my t56 swap and getting stuck now.

 

 

Is there any chance that things aren't right farther down in the case, and it won't let things slide down where they need to be so that it'll fit?

Or are you staring at the tail housing and you can't get the bolts to go through the plate to the case?


I'll go take a look at my tail housing and tell you what I find.

 

The shaft the reverse idler gear rotates on it not physically long enough to support two thrust washers, the gear, and bolt on the plate. In other words, the plate supports the end of the shaft and with the washers the shaft is just not long enough to go into the middle of the support plate.

 

I took my idler gear out and found a washer on each side. Just one on each side though. It appears they do spin so it's probably a good thing to have them in there to keep the gear or shaft from wearing the case.

I did notice that when I was putting the shaft back in that the idler gear sits on that I didn't get it fully seated the first time.

I also noticed that the idler gear wouldn't seat fully down unless the funnel is fully seated along with the spacers/bearings above it.

Maybe one of these things is keeping it from sitting down far enough that the spacers will be needed.



Did you figure out what is going on with the rear mainshaft bearing?

 

Are the washers you are referring too about 1/8" thick each? Their is just no way I can get my washers on, even one, and still have the holding plate mount flush with the holes. I know this have to be simple. I just can not see it.
Thanks for the reply.

yes they are about an 1/8 inch, maybe a bit thicker. They have some slots leading outwards from the main hole as well.

 

Well crap. Those are the washers I have then. I guess I just have to figure this one out on my own.
I know this sounds dumb but is this the correct order of assembly?

1. Shaft into tailhousing.
2. Thrust washer on shaft.
3. Gear with roller bearing on shaft
4. Thrust washer on shaft
5. Plate.
