4.3l REAR MAIN SEAL HOW TO REPLACE

How hard is to replace a rear main seal on a 1995 GMC Jimmy 4.3l engine.
I have the transmission out and was thinking I should replace the seal since I am so close to it. It looks like I need to replace the flex plate anyway because the holes to the torque converter are egg shaped.

By asking this question, I know you are not capable of performing this repair. I hope you can get your vehicle running again.

I have already replace the flux capactor as shown on the great flux capactor WEB story. I was thinking the main seal was behind the flux capactor however I was only able to find the duhickkey that was behind the what do you call it. I was hoping by wasting more time on the web instead of just replacing the seal it will replace itself. http://www.break.com/pranks/flux-capacitor-tempe12.html the flux capacitor - Video Dailymotion

This is what my flux capactor looks like


This is what the WEB says my seal looks like.


This is an inside view of my motor from the repair manual I purchased on EBay. I know how to take the bolts off the flywheel but I do not think I can run fast enough not to get killed when the flywheel falls off.


Other people that been very helpful on all sorts of things.

Im only helping because of buttsex in Belgium. You can drill a couple small holes in the metal part of the seal, thread in a couple small screws and use those to help pry the seal out. Carfull not to hit that gi-holy-mother-fucking-gantic crankshaft with the drill bit.

Pretty damn funny I will contribute...

BEFORE you put that new seal in. Check the inner part of the seal itself. The oil wiper faces inward, and make sure it is facing inwards before trying to carefully tap it into the rear cover. Throw the plastic guide fucker the seal normally comes with in the trash and use some sense and use a feeler guage to walk around the oil wiper making sure its facing inwards.

Tap the seal housing into the rear cover to where the bevel on the housing ends at the back part of the rear main seal surface.

I passed on your instructions to my helper. She says she does not know what you are taking about but will give it a try anyway.

The below picture is her looking for the rear seal to replace.





She is sending over her twin brothers to help.
