Re: TR3 "Front" Main Oil Seal:

Howdy Folks,

I was visiting my Brit Car Guru yesterday & hanging some completed items on my engine (Looks pretty dang good by the way). I would have taken some pics but I forgot my camera (Next Time).

Anyways; While the Engine is out; We`re going to replace the "Rear Main Seal" (Not a Problem). The question I / We have is; Does the "Timing Chain Cover" need to be removed to replace the "Timing Chain Cover Oil Seal" or is it "Easily" accessible without removing the "Timing Chain Cover"?

Thanx in Advance for the advise,

Russ
 
Re: TR3 "Front" Main Oil Seal:

Yes it has to be removed.....the oil seal is fitted from inside the timing cover.

When re-fitting the timing chain cover, it has to be left barely finger tight until the pulley is pushed onto the crank. This centres the seal before you tighten the timing cover.

If the pulley sealing surface is scored, use a thinwall sleeve on it, or the new oil seal usually starts to leak fairly quickly.

Howdy Viv,

"Thanx" very much for the info.

Re: TR3 "Front" Main Oil Seal:

Just to emphasize what Viv said, my suggestion is to polish the hub where the seal rides on it, and if you can't polish away the mark, then use a sleeve. Here in the US they are commonly known as "Speedi-sleeves" (a brand name). You may have to call around a bit to find a shop that can order them in the right size, one of the NAPA stores in my area could, but the closest one couldn't. Take the hub along when you order, in case the applications book no longer lists the TR (I ordered mine by size, but discovered it was listed, at least then).

Be sure to smear both the hub and seal with a little grease, so it's lubed when you first start the engine. While you are in there, I'd replace the tensioner too (mine broke the year after installing the sleeve).
 
Hi everyone, my front main seal on my 1961 Triumph TR3 is leaking pretty good. Can this seal be replaced without removing the engine? Thanks!
 
Screw the seal ,you MUST replace the timing chain and tensioner.Buy a speedy sleeve to make the new seal
not leak oil. Do it right and you wont have to do it again. Easily done in car, under an Elm tree as I recall...

From what I remember, the engine does not need to come out, but the radiator does. The issue is removing the fan extension, which is hard to do unless you pull the radiator.
 
The drag link will also be in the way, a bit,but can be gotten around as well.
If you are digging this deep I suggest also fresh motor mounts, hoses , Delran bushes on the draglink
and a fresh idler arm assy, All these bits are easily done with the rad out.

yes you can replace the seal with the engine in the car, but like said the readiator needs to come out and the apron needs to come off.
