Anyone ever install one before? …as I remember the front seal actually seals on crank pulley and this thin metal seal goes on seal surface of the pulley. I have never put one on anything before but I would assume heat it in oil so it will expand enough you can quickly slide it on.
Think my pulley has groove worn in it.

 

I guess you mean in the front cover. Front harmonic balancers usually have a groove or 2 for throwing oil back. I don't know what soaking in oil might accomplish, maybe a film of oil.
The oil pump is on the other side.

 

Thats the seal Im talking about but the seal repair kit wont be in manual…but Rockauto does list one for it. It has a thin metal sleeve that you heat up so it will expand so you can slide it on into place and hold till temps normalize. Kind of re-surface for seal area…in this case the surface is on the crank pulley

 

not hhr but same situation

 

Seal repair kits. Remember trying those things back in the 1980’s. Never had much luck with them. Usually wound up selling the customer a new harmonic balancer.

 

what was the trouble you had with them?
Im thinking maybe clean the balancer up good an sneak it in wifes freezer when she aint looking….put the sleeve in the oven on about 400-500F for while….should just drop on there or at least be lot easier going on

 

You need to determine the leak, gloves in the harmonic balancer , cheap crap seal? I found that FelPro seals leak, OEM GM originals don’t.
no need to soak the seal just apply to the seal, GM seal comes pre greased leave the green protection disc in place . Push the seal into the front cover , and reassemble

 

Maybe just the seal as you say, but seems like pulley surface had some groove wear to it so I just ordered new GM seal and National brand Sleeve kit for it from Rockauto just in case the groove is worse.
About 99% sure coming from timing cover seal and pulley slinging it up on bottom of accessory belt tensioner arm. I washed it all off couple weeks ago….took it a while for any to be seen but its back now keeping that side of the car from rusting…lol

 

Still leaked. A sleeve will increase the diameter of the pully shaft. Might just be a few thousandths but the seal has to stretch more to fit over the larger diameter. Maybe they overstretched the lip of the seal ?

 

Hmm…ok
