I'm rebuilding a Snap On SL 715 1/2" and F735 3/8" ratchets, and hit a snag....how do I replace the rear covers/top plates? Do I simply drive them out, and if so, which way?

From the looks of it I would say they would drive inward towards the "guts" of the ratchet. I would imagine there is probably a seal of some sort that is involved somewhere such as an o-ring.

I just did a quick internet search and found a youtube video showing how to rebuild a snap-on SL720 ratchet. The guy starts this particular part of removal at 2:15 into the video.

This, the knurled ring holds the cover plate in place, the plate just spins without the ring.. I found a few different diameters of aluminum and brass bar stock and used them as drifts to pound the old out and install new (with ratchet body in vise) hardest part was making sure new plate didn't go in crooked.

I never did get a chance to watch the YouTube video, but figured it out myself. The rebuild kits actually come with a replacement inner "ring", so I knew it had to come out. I used a socket and pushed the cover and ring out with a vise, and then seated the new ones the same way. Only problem I had was keeping the logo lined up correctly, ended up taping it in place until the ring was seated.

One thing I forgot to mention, the rebuild kits include a new selector and selector center pin. The selectors have a square drive that fits into the pawl, and is held in place with a pin. This pin has to be mushroomed out on one end, otherwise it will simply fall out...I'm not sure how Snap On does it, I just tapped mine down with a ball peen hammer. The pin on the SL715 was actually a little longer than needed to be, so I had to cut it down a hair and then peen it over.

They use a center punch. If you look at old Snap-on ratchets that have never been rebuilt, you'll see a center punch mark dead center in the middle of the switch stem.
