tr4 O/D Rear Seal

[PaulR]

Hi All

Just about to begin the rebuilding of my '64 TR4 Overdrive Gearbox and want to replace the rear seal which I believe to be at the end of the O/D casing

My question is whether I have to dismantle the O/D to do this or if I can prise it out without dismantling.

The O/D works perfectly and so I am reluctant to dismantle.

Any thoughts please

I had mine completely to bits so can't be sure but I would expect that you can do this.

 

The hex-nut on the end will be very tight I expect. You will need a flat-bar bolted to the flange.

 

The tail-shaft bearings on mine were the tightest thing I have every had to pull.

I pressed them out with a piece of 1/8 stainless plate bearing agianst the hex nut, partially undone of course.

 

Afterwards the stainless plate had a dimpled witness mark of the hex-nut pressed into it.

The shock released when this popped left my hand numb for a few days.

 

This was the only bit of the OD dismantle that gave any trouble at all.

 

So I hope you can get the seal out without all this.

 

I seem to remember just winding in a new seal with the flange nut and some packing washers.

I changed the rear seal in 2 ODs (A type) recently without removing the annulus or bearings. What made it easy was the use of a lever type seal puller that has a hook to engage the seal.
