Leaking front seal

Winter has hit, and my front oil seal has started leaking! Is this a hard item to change? Somebody said pull the engine to do it? Any body got a good repair manual on these old trucks? Mine is a crudy manual that shows all about the gas version, but hardly crap about the diesel. Truck is a 95 F350 4x4 7.3. Also having some starting issues, so a diesel manual would help with this. Thanks fellas.

Front seal as in the from crank shaft seal?

Remove belt
remover harmonic balancer
remove LPOP cover(Four 10mm bolts)
remove seal

Reverse for install. About a 2 hour job if you have several beer brakes

what're "beer brakes"? are they special brakes you can install for stopping at the bar for beer breaks? :-)

sorry, Brad - I couldn't help myself!!

on a more constructive note - is the special installer tool stated in the manual actually required, or will a dull punch (or similar) work fine if used carefully?

mmmmm, beer brakes...

Special tool? As in a piece of pipe or large socket

is that all it is? is it the rear seal that needs a tool? I've never done one, but have one on the to-do list (though I forget if its the front or rear leaking now) and I thought I remembered reading about a seal driver tool in the manual...

maybe it was one too many beer brakes that day and I imagined it.

(and c'mon, that beer brake typo was funny! ...at least the funniest thing I've read today on this boring Monday)

I think ANY seal I have installed called for a special tool, you just have to improvise. I have put in over 100 seals and yet to have one fail.

if you end up not having the right size, your local hardware store should have PVC pipe in various sizes.

good to know - thanks guys. how about pulling the old one out? dental picks and needle nose pliers?

I think the manual lists a special tool for the remover as well. ...even I knew that was BS!

head down to harbor freight and grab one of these....

Seal Puller

or use a screw driver to pry it out if you have no room for it.

I have not done this specific job but the harbor freight tool worked really well on my tranny seal on my BMW.

I used a big socket for the front seal and a 2x4 for the rear. Just make sure it goes in straight.
