timing cover seal

[DJK]

Confused as to proper installation of timing cover seal. The old seal had a smaller diameter section that was towards the pulley. The new seal (Fel-pro kit #TCS4155-2) also has a smaller diameter section, but looking at the seal lip, I would say the small section goes in toward the chain instead of out towards pulley. Any help greatly appreciated. 52 Cranbrook

I can't recall if the the seal has a spring but if it does the spring "goes toward the oil", in other words, toward the chain.

I haven't checked for a spring,but just looking at the seal lip, tells me it goes in opposite of the seal I took out. These old cars are a whole new learning process. I am on hold w/ Fel-pro hoping to get an answer from their tech guys.

Thanks for the tip.

Sam, just checked, there is a spring so I will install with spring towards oil. Thanks again.

When you look at the seal lip you want to install it so that any internal pressure will tend to force the seal into the crank rather than let it flow past the seal.

when you get your seal installed...assemble with all bolts loose before the hub in on the crank...the hub is what centers the cover for centric location of the seal and prevent premature wear....after the install of the hub..you can then torque the bolts.

I actually made a centering tool from 1 1/2" ID pcv pipe and duct tape to center the cover. If I had a brain, I would have drilled the cover in two locations in order to install dowel pins to maintain position, assuming it previously was centered.

but you were spinning wheels and reinventing things already incorporated to the engine that is many times over more accurate.....

My hub is a very tight fit, I actually used a wheel cyl hone to clean the bore for a better fit. Still had to gently tab it on with a plastic dead blow hammer.
