Transmission End Play (stock 41)
I've rebuilt the tran. And in the final stages of assy. I do have a little bit of end play when pulling on the spline rear shaft (1/8 inch approx.) Based on what I've read on Vapelts Web site (super helpful) that is not acceptable. I'll call them Monday as I believe they have washers for this issue.
Would like to hear from someone who may have dealt with this successfully. Bob |

Re: Transmission End Play (stock 41)
Do you have the universal joint installed on the end of the shaft? It took all the end play out of my 1937 trans when the joint is bolted in place.

Re: Transmission End Play (stock 41)
There's the problem. When you tighten the ujoint, it pulls the output shaft tight against the rear bearing.

With that said you have to have the transmission mount on the box to hold the rear bearing in (or it can move backwards) - so if you don't have the mount on, then use a 3/8" bolt with a big washer and thread it in the back so the washer holds the bearing in place. |

Re: Transmission End Play (stock 41)
Veeder - when you mention play - what is it? Is it the main-shaft moving inside the bearing at the rear? I've never seen that - so please explain?

Re: Transmission End Play (stock 41)
So explain how it works when you have an open drive transmission shaft with a slip yoke on the back? Same transmission, just different main shaft. I will checkout both main shafts tomorrow . . . as I'm curious myself.

Re: Transmission End Play (stock 41)
The open drive rear bearing is retained on the shaft by the speedometer drive gear and a snap ring. I've found the speedometer gears to be in slightly different widths to minimize the end play when the snap ring is put in place.

Re: Transmission End Play (stock 41)
The front and rear bearing outer retaining snap rings must be of the proper thickness as the originals. 0.075-0.080"

Re: Transmission End Play (stock 41)
Back in the day, we we would meadure the distance between the inside of the two retiner rings on the fron and rear bearings in a lathe. with the assemble held tight, all .006/.008" and machine the case to match. Tis kept the trans from jumping out of 2nd. it also kept them together behind the Oldsmobile engines. Later I was told this was wrong and you should use shims, but I don't know where you'd put the shims. It was about this time the cad/LaSal trand got popular. Maybe somebody will remember this.

Re: Transmission End Play (stock 41)
The shims would be correct prior to loading th u joint. Do you have VanPelts book? it goes over this aspect.
