TerryB 1,360 Posted August 3 (edited) Looks like a tool for seating axle seals or brake drum grease seals. Edited August 3 by TerryB (see edit history) 1 Share this post Link to post Share on other sites

Craig Gillingham 77 Posted August 3 I've got one of those, and I believe it's something to do with a transmission. I'll be able to tell you tomorrow when I get home. Share this post Link to post Share on other sites
intimeold 91 Posted August 4 (edited) Definitely a seal driver/installer From the second picture, you can see that this tool is made to go over a shaft, such as the transmission tail shaft. The new seal would be placed on the driver, then slide the tool and seal over the transmission tail shaft, and finally with one good solid hit on the driver with a hammer, the seal would be installed to the proper depth in the transmission.

Frank DuVal 570 Posted August 4 I've seen several sizes of these tools. One is for rear axle seals on late model Corvairs. Others are for most any other seal on a GM car. 6 hours ago, broker-len said: J3615 What did Google say? 1 Share this post Link to post Share on other sites

chistech 1,934 Posted August 4 I made up a similar unit to install the felt seals in my 32’ Olds rear axles. I used PVC and softened it with heat to flare it out. If I can find the pictures, I’ll post them. Share this post Link to post Share on other sites

Others are for most any other seal on a GM car. What did Google say? The tool design, is for all modern transmissions, not brand specific. What does matter is the size (diameter) of the seal. With one hand hold the tool and with the other hand "work", the seal onto the tool. The seal will stay on the tool; and compress the rubber sealing surface, just a little. Remember, there is a spring in the seal lip; so the tool exerts a little pressure on the rubber and spring, to protect the seal from the splines on the tail-shaft during Assembly Share this post Link to post Share on other sites

joe_padavano 1,116 Posted September 7 Kent-Moore manufactures the "factory tools" that you see called out in the factory service manuals. Typically GM, but they also do tools for Harley Davidson, Saab, and even John Deere. High four-digit "J-numbers" are typically mid-1960s vintage initial release, but often these tools have applications over many years, if not decades. As noted above, this is a seal driver of some type. You'd need a vintage Kent-Moore catalog to find the exact application. 1 Share this post Link to post Share on other sites

I have some of those old Kent Moore catalogs, but as you said, the tool is useful in MANY applications. 1 Share this post Link to post Share on other sites
cheezestaak2000 71 Posted September 7 in simpler terms, it's a tool to install whatever seal fits on it for any type of application. yes, often referred to as a J tool. Share this post Link to post Share on other sites
