help with shaft from water pump

I am assuming you are doing an electric water pump? The bearing for the water pump shaft is press fit into the block. Knock it out with a socket. Then just plug the hole in the timing cover.

yes the water pump.. do i need to remove the timing cover to do this? if i know it off with a socket will it be in the timing cover?


wolfman had retyped your message in lower case.

be very carefull putting in the new seal for the shaft. you need to press it on perfectly or you will leak. been there done that.

Rufrider, I was doing the cam at the same time as the water pump, so I had the intake off. I'm not sure what you're supposed to do if you just want to do the pump because I don't think it's a good idea to leave the shaft in there. The reason is that there is only one bearing and on the other end is the seal to keep it from wobbling. Then you have the gears meshing somewhere in between. There could be inconsistent gear engagement and grinding if that shaft starts moving around with no water pump bearing to support the other end.

On the other hand, I think some guys have just left the shaft & gears in there and maybe you can check on a few forums to see a consensus whether or not there is long term damage from leaving it in. If the seal is good & stiff, maybe it will just sit there & turn, but I looked at it and decided the shaft had to come out. Obviously, this presents a problem for the guy who just wants to do a pump upgrade and not open up the engine.

The other thing, is that you can use a much cheaper timing set because you don't need the fancy water pump gears that only the LT1/LT4 uses.

okay i decide to remove the timing cover and replace the chain. waht timing chain set up can use now. any for a small block?. i have stripped my pulled trying to remove the snout of the dampner. any tricks to this?

[Joe 1320]

The damper bolts to the hub which is press fit on the crank snout. After the damper is removed, a high quality steering wheel puller will remove the hub.

[rufrider76]

i guess the auto zone special wasot a good puller. i strripped the cente bolt on the puller

When pulling the 3 pronged hub off the crank, you might have to put something in the bottom of the threaded hole to push against because the hole in the back of the hub is the same diameter as the threaded hole in the crank. If you don't take this precaution, you might be pushing against the hub itself, and not the crank. In that case, you will break something if you try hard enough.

I think that I got a piece of 5/8 fine threaded, hardened rod to use witht he puller. And I also used another piece of the rod along with some nuts & washers to act as an installer to get the hub back on there.
