Question Pulling Crankshaft Damper

I am pulling the crankshaft damper off my 1994 Ford Bronco.

It has 5.8 liter V8.

My true goal is to pull the timing chain cover and replace the chain, gears and cover plate gasket.

All is going well, except I am not certain how to remove the crankshaft damper bolt. The service manual just says to remove bolt. Use a puller to remove damper and off you go.

The crankshaft wants to spin as I turn the damper bolt. I am not certain of the best method to hold the damper fixed as I turn the bolt?

Any suggestions?

PS I know this is a basic question. But the mechanic wants $1,000 to pull the cover and fix the gasket. He is advising the total cost will be $6,000 to replace the engine and transmission.

I think for a couple of hundred I can replace the gasket myself. I am not so certain about the timing gear.

Re: Pulling Crankshaft Damper

Use a rattle gun to remove the bolt, and a harmonic balancer puller to remove the harmonic balancer.

Re: Pulling Crankshaft Damper

Thanks Rick,

I do not have a rattle gun, just an old fashioned socket set.

When I try and turn the socket it turns the engine over.

I was going to place a screw driver in a hole and just heave on the socket, but I was concerned it might bust up things.

I will see if the stearing wheel puller I own will work or not. If not, I will either rent a puller or purchase one.

I am feeling good so far. No broken bolts.

The mechanic was affraid of broken bolts. I am half tempted to button it back up and take it back to them.

I do need to replace the power steering pump. This one has a terrible leak.

Re: Pulling Crankshaft Damper

If it's a manual, you can also put it in gear, with the handbrake on, that sometimes works. Next method is to scew two long bolts into the harmonic balancer and use a lever against the bolts to stop it spinning whilst undoing the main bolt.

A steering wheel puller may work, but they are sometimes made a bit flimsy, harmonic balancers sometimes take a lot of effort to remove.
They are usually only $25 or so to buy anyway.

Re: Pulling Crankshaft Damper

Take it somwhere else $6000 is way too high. it should be a grand to remove the engine and $500 for trans at the most. Thats what i paid to get the 5.0 out of my ute stripped down except heads and crank etc, cam put in and back in again.... Actually even those figures are high.

On my old EL6 i removed the bolt with a socket short poll braced to the ground and a quick flick of the starter motor. I was only fitting up a blower pully though. Hope this helps.

Re: Pulling Crankshaft Damper

I had to replace the timing cover and water pump gaskets on my xr...and me and my dad didint have a harmonic balancer puller, we managed to wedge a piece of wood and the socket wrench somewhere next to the balancer cant remember were exactly and cranked the engine to break the seal on the bolt....It worked.

I wouldnt recommend it but we did do it on two occassions and nothing broke.

Re: Pulling Crankshaft Damper

Success!!!!!!!

It is off, the cover plate is off and I still have my front teeth.

I did have to drill hole in a steel plate stock, use a 4' steel pipe on my breaker bar.

I also destroyed an inexpensive 1/2 drive socket wrench.

I also had a timing gear puller.


But - I also had an blown v-8 buick 308 that I used as an practice tool.

Now - Timing Gears???
