external shifter seal

Postby Gordwing » Tue Mar 13, 2012 7:35 pm



Can anyone tell me how to get the shifter extension off the spline to change the seal. I can't get mine far enough off the spline because it hits the frame.Hopefully I don;t have to move the motor off its mounts???

Your not gonna like this very much,but I just went through this on my 88.
Have a look at these 2 posts.It was my final cure for a design flaw(my opinion only)

The pinch bolt rides in a groove cut into the shaft. It needs to be completely removed. The lever should slide off at this point. Hopefully, the shaft is not flared on the end.

It's not flared and does slip off,but you have to remove a few things to get enough clearance to get past the end of the shaft.It's really cramped in there.The seal can be 'picked' out easily and a new put on and tapped into place.

My problem was,the weeping of oil past the seal.The seal was OK , the shaft had a lot of lateral movement in it.More movement than the seal could flex and still seal on the shaft.
Just replacing the seal on mine would not stop the weeping and coating the side of the block.

Rather than pulling the motor,splitting the case,replacing the shaft and needle bearing,I opted for a external support bearing.
It was a lot quicker,cheaper and keeps the shaft rock solid.

I've read that many owners have this problem and just live with it.

I do believe it it a poorly designed shift arm mechanism, and I just wanted better.
There's just too much leverage on the needle bearing for it to hold up for 30+ years of foot stomping on it.
I am confident that my shifter shaft will never leak oil again(keeping my fingers crossed)

Thanks for the reply! My '88 has some play in it which I'm sure is the needle bearing, and I will probably end up going the external bearing solution also.

When I made the external bearing holder,I tapped 3 holes in it and used lock nuts on the set screws.This allowed me to set the carrier and gently set screw lock it it place.With 3 points of contact,It allowed for alignment errors in the carrier so there isn't any bind on the shaft.It just holds it steady in the middle.
Engineering the mount wasn't critical in measurements,it just had to encircle the bearing.The set screws do all the alignment.
I robbed the bearing from a junk electric motor.Many of them use the same size.I had to buy the spacer,set screws,bolts and washers.
Drilling and tapping the shaft wasn't too bad,just keep cleaning out the hole of the cuttings.
There's no real torque on the bearing to speak of,so I tapped only about 3/8'' into the shaft.
If you have any questions,just ask or PM me.
