Leaking Muncie Countershaft

[Dave K.]

I plan to repair the leaking countershaft on my 66 roadster tonite. Plan to seal the leak by moving the trans back to access the countershaft case area. Can the trans be moved back without the need to drop the driveshaft? I figured that the shaft would slide back about 1 to 1 1/2 in or so on its splines without the need to drop the shaft.

I was able to stop that type of leak in a friends car by moving the transmission back about a 1/2". Used brake clean to degrease the area and applied RTV using a putty knife. I let it skin over and retightend the bolts. That was several years ago and still no leak.

install a couple of 1/2"-13 X 3" long bolts in the top 2 bolt holes in the bell housing to let the trans rest on when you pull it back

Clem,

Already plan on to do that.

Dave;

I just did this with my T10... Dropped the drive shaft (just removed the front U bolts) and removed the shifter bolts. I drained the unit.. Loosened the tranny bolts and slid it back roughly 1 1/2 inch. Cleaned the area and used Permatex Black with a small piece of paper gasket cut to size to cover. I snugged it all up and let it set 24 hours before I refilled the unit..

No leaks!

Good luck,
Joel

joe,

Is there really a need to remove the shifter bolts? I agree with dropping the drive shaft but do you need to remove the shifter bolts?

Hi Dave,

On the shifter bolts, what I found was that my shifter (1963) prevented the tranny from moving rearward as much as I wanted... With the bolts removed, I picked up some "wiggle room" which did the trick. To be honest, I did not start out to do this but, for whatever reason, found that I could not get the clearance I wanted.

On the drive shaft... just remove the front U bolts and slide the yoke forward into the tranny.. the drive shaft will drop down out of the way.

Doing this is really not all that difficult... I have one of those Quiklift units so I had the car a decent distance up in the air which made the whole process quicker. My guess is that the whole thing took like 90 minutes, including the time to figure out what to do...

Have fun!

Re: Leaking Muncie Countershaft

Without removing the front U-joint nuts and trans shifter it sounds like moving the trans back 1/2 inch, or so, in order to gain working room 'works'. .. Is that so? .. . Just trying to minimize 'concrete time' on the 'ol back. ..
Old guy disease. . .. ..

Working underneath the car...................guys with the lifts must be in HEAVEN!

Re: Leaking Muncie Countershaft

You can certainly try that... The half inch was too small for me to get my fat fingers in there.... The quiklift is relatively new... I used to use 6x6 blocks stacked 3 high... the new way is better!

If the counter shaft is leaking on A muncie the case is egg shaped were the shaft goes through the main case .This is supose to be a press fit. Do not ever get on the car very hard because you will strip the teath off of the input gear and cluster gear . Proper way to fix this is to pull the trans out and have A bushing put in the case .
