I'm going to replace the water pump, all belts, cps, and front seal. What sort of puller do I need to pull the damper and timing belt pulley, and how are they pressed back on? I'd like to do this without having to interrupt with trips to the rental/parts shop. I can dream, right?

I went to Murrays..There is a Crank Shaft Dampner Pulley Remover. The will take it off and get it back on. They charged me $50 to rent it. When I returned it I got all my money back. The pulley is very hard to get off I would recommend a Air Powered tool to get it off.

You will also need an air tool to put the crankshaft pulley bolt back on. I tightened as much as I could by hand. The thing kept spinning so I could not tighten it anymore but apparently is was not tightened enough which lead to a shredded belt about 2 months down the line.

You can use a cheap steering wheel pulley to get it off.Gear pullers will chip the outter edge of the pulley.I put mine on with just a breaker bar over a year ago with no problems.Of corse mine pulley went on much harder that Blast7`s though.Most air tools aren`t strong enough to loosen the bolt,use the starter trick with either a breaker bar,or 1/2 drive retchet.

If the pulley is clean it may come off easily. I have pulled several off and had to use a puller only once. That crank bolt can be a real pain, it is easier if you have a MTX tranny,,put it in 4th or 5th to hold the engine, and apply the brakes. Or some guys use the "starter" method. If you do need a puller, any type that uses only 2 bolts works fine, be sure to put a large nut or something between the puller and the crank to prevent damage. The pulley has 2 bolt holes in it, use those, not the edge when pulling it off.

I heated the bolt, and used a ratchet with a LONG (3 foot) steel gas line pipe on it. Came off no problem. You can rent a harmonic balancer puller at Autozone for like 10 bucks which is fully refunded when you return it.

Ok, thanks guys, looks like I have plenty of info to remove the pulleys. How about getting them back on? Will they push on far enough to use the bolt to finish the job? Or do they just go on by hand? The only reason to take the timing pulley off is to change the front seal, which isn't leaking; I'm wondering if that is really necessary? How long do they last (now at 130,000 mi. and counting...)
Thanks again for the info.........

To remove the damper pulley, you should use a puller that is congiured to use 2 or 3 bolts to attach to the pulley/gear. To remove the timing belt pulley from the crank, you can use the same puller, but many sets don't come with the bolts small enough for this pulley. The MTX SHO is kind enough to provide the exact bolts necessary in the lower timing belt cover - the two long bolts. The ATX cover only has one ot these bolts.

You must remove the damper to replace the timing belt and the CPS, but you only have to remove the timing belt pulley to replace the front main seal.

To torque the damper bolt with a MTX, put the shifter in 4th gear, have someone step on the brakes and torque away. For the MTX and ATX, you can also use a large C-clamp on the damper and let it press against something very solid as it tries to rotate.

Also, to remove the damper bolt, you should apply something cold to the bolt. Adding heat to the bolt will cause it to expand and hang on to the threads even more tightly. I found that using a little wet sand paper on the crankshaft created enough heat to prevent the timing belt pulley from fitting due to the thermal expansion of the shaft. Remedy? I placed a couple of ice cubes on the crankshaft and the pulley slipped on easily.

Any suggestions on how good the gasket is on the rebuilt front half pump? I'm thinking of using blue RTV in place of the gasket, anyone with any experience in this?

The gaskets that have come with the A1 Cardone rebuilts have not leaked in any installation. Why would you try to reinvent something that works as designed?

When I received my waterpump it did not come with new gaskets so I used a little bit of blue RTV with the old gasket and so far so good.

Well this sux...
I just started on the water pump & timing belt change and shotimes is down...
no manual..nothing...gotta go by instinct..

Cant get the freakin crank bolt out..using a 3/4" impact wrench.. but a 3/4 rachet and long pipe is on the way...
Im guessing that you cant get the lower & middle timing belt covers off without the crank pulley off eh?

So I changed the oil while I wait....

Did I mention this sux??

I know I'm repeating what has just been said but I am in the middle of this (everything apart, just need to get it back together).

To get the crank bolt off, put a 3/4" impact socket in your 1/2" drive craftsman lifetime warranty socket wrench or breaker bar. Lay it against the front of the subframe. Make sure the DIS and coil pack is unplugged and go bump the starter. You'll hear a crunch, and find that the bolt is loose. Scary, but it works.

Use the aforementioned 2 bolt puller to yank the dampener. I bought one at Sears for $20.. can't go wrong. I didn't need an air tool to pull it off, just a 3/8" socket wrench with a 16mm socket on it.

The bolts that come with the puller won't work. Use scott's method of scavenging bolts from the motor to use.

The pulley should come off nice and easy.

SHOtimes is accessable through the IP adddress. The domain name server is down. The address is http://216.92.187.145.

The lower timing belt cover bolts I referenced from the 3.0L engine were used to pull the timing belt sprocket off the crankshaft to get to the front main seal. Those bolts will not fit the damper. Most damper pullers will come with the correct size bolts for the damper.

Refer to the image below to see how to properly use the starter method to loosen the crankshaft damper bolt. The crank rotates clockwise. make sure the wrench is resting on the subframe in the position shown.

You can scavenge bolts from the motor to fit the dampener. This is what I did.

My puller came with four different sizes of bolts, but none of them fit properly. The closest was M8x1.25. I'm guessing it's a M8x1.5 thread.

Possibly the rented pullers will have the right size bolts.
