I'll give that a try. Do you use the block to move it all the way, or just far enough to engage the crank bolt?

You can borrow a real HB installer from Autozone of O'Reilly. You can use the big hammer approach, but you risk screwing up the thrust bearing in the engine... does a 4.9 even have a thrust bearing??? I would not recommend using the crank snout bolt to pull it on either. Too easy to strip the threads.

I wonder if any of the bolts go thru to the water jacket? When I changed the pump on this 4.9 the bolts all had sealant on them?

What determines if the timing chain needs replaced?

ANY slack in the chain, @/or check the teeth on gears for wear-the amount of chain slack will sorta match the amount of gear wear. If
the motor ran before a tear down-did it crank hard, run rough, not start or back fire? lots of miles could be an indicator also.

Just enough to get the bolt started a couple threads is fine. The more the better though. The crank and bolt are hardened but the bolt "could" still be stripped. I use an impact gun after that. I've never had a problem and I've removed and installed this pully 6 times on my engine.[This message has been edited by Fieroseverywhere (edited 01-15-2010).]

Yes, it has a thrust bearing. No you do not need a BFH to do it. A smaller hammer works just fine. Its more the vibration that moves it then the force of a big blow. The wood block spreads out the force and keeps the pully perpendicular to the crank which aids it going on. The thrust bearings purpose is to absorb the movement of the crank. The force of the hammer is less then what the crank sees during normal use.

No, they don't. The sealant was probably just there from someone going overboard puting it on. The pump itself has only 4 bolts that even go into the block. All the others just secure it to the timing cover or screw into the inlet on the backside. 
EDIT: This pic pretty much summs it up...

Vibrations eh. I guess I can use the air chisel to vibrate it back on the crankshaft. I'll try this today. Might just be an ideal way to get these back on.
The Haynes book I have says on 91's up to just use the crank bolt to pull it back on the crankshaft nose. I would think after it was on enough to engage some threads it will be fine.
I was a little concerned about about hammering against the thrust washer, but I had forgotten all about the " hits" it is taking while going down the road at 70 MPH
