Front oil seal HELP with.....

[Gliderman8]

<span style="font-weight: bold">getting the crank bolt out!</span>
From a previous post you may know that I had a leak at the front of the engine and found it to be coming from the timing cover oil seal.
At this point I have the radiator and fan out. I now need to remove the 1.125" crank bolt.
How can I keep the crank from rotating so I can loosen the bolt?
I did try putting it into reverse, but no luck and there is no-one here to stomp on the brakes.

By the way, car is up on jack stands and I hate to take it down... Any suggestions?

I think I just used a short breaker bar, and smacked it with a hammer. The engine will turn over, but eventually it should come loose.

An impact wrench would probably be better.

1/2 " impact with a good compressor for my Wedge last year

It been so long since I removed it when rebuilding the engine but, is the bolt a standard threaded bolt.... does it loosen to the LEFT and TIGHTEN to the right?

When I took mine off to install fan eliminator I used a 18" pipe wrench on the hub outer flange.Left a tiny mark,but Im not reusing it.I tried two different strap wrenchs but they slipped.

Tom- I also thought of the pipe wrench but I intend to use the stock fan and really didn't want to chew it up with pipe wrench teeth.

You are probably right don... I just may try giving the ratchet handle a good smack with a BFH.

Fourth would be a better choice for attempting to hold the engine from turning with the brakes.

You could also try a strap-type wrench on the extension.

That's right; Counterclockwise will loosen it.
If you installed it, you probably tightened it with 90 ft-lbs at least. I'd go hunt up an impact wrench. I wouldn't use one to tighten it thoughg unless it has a way to control the torque.

OK, looks like I will be on the hunt for an impact wrench...

As noted, 4th gear and lock the e-brake tightly.

Another option is to put a breaker bar on, arranged so the handle will hit a frame member (or the floor) and then hit the starter.

FWIW, the Stag maintenance manual suggests using a pipe wrench on the fan extension.

I've always done this one Randall suggests...prop up breaker bar, push starter...no drama but bolt is loose

 

[hooey]

do like prb51 told you with the starter
it's hard on the clutch springs trying to take it off holding it in gear with the brakes on I done this over 100 time with the starter

Some great ideas that sould work fine have been mentioned, I just made a tool out of some scrap metal.

Funny you should mention this because I was thinking of making something similar... Thanks!

Impact wrench. You can rent an electric one.

David K wins! An electric impact is what I'd suggest. And again: DON'T use it to reinstall.

I've used the breaker bar/starter tap method as well but it tends to be a bit frightening.
