TH400 Front seal tool... - The 1947 - Present Chevrolet & GMC Truck Message Board Network

There's a special GM tool for banging in the front pump seal on TH400's. What's the part number? Anyone?

Yes, I know about using a big socket, or pipe. I just need the GM number...

Someone must have a Kent-Moore tool catolog.

If you have access to a shop manual from Chevy it might have it. If you don't get any response by the time I get home tonight I will look it up for you.
And you dont look like you ate the whole pizza. At least you didn't have to hold your pants up because your gut was forcing them down like mine did. LOL

I got the Kent Moore catalog yesterday, and I'm not seeing it in there. Looks like tons of tools for anything 1998 and newer. I'm going to call them today.

Anyone else?

Here are two options:
1 Part # YA322 seal driver kit from Snap On for $78
2 Small ball peen hammer from Sears $10 appox. and tap lightly around on the seal until it is seated.

Screw option 1. I'll make my own tool before I spring for an entire set of drivers.
