Transmission Seal Pullers

[st@rk]

Hi guys, can anyone recommend specific or certain styled tools for the removal of transmission seals?

Most pullers look pretty flimsy and are more suited to o-rings etc rather than larger seals like driveshaft seals etc.

Thanks for any help!

I've probably used a dozen brands. They're all exactly alike in the business end. Difference seems to be the handle. Flat bar handle vs pipe/bicycle style grip handle. You're not exerting much force so the length isn't important. Too long is probably more of a problem than too short. But I've never seen them any length than the usual "hammer handle length".

There's nothing to break. No critical tolerances. No bits to go dull. You can pull a seal just fine with a piece of wood cut into a long triangle. Or a plain old flat blade screwdriver if you're careful not to nick the seat.

Home handyman or professional transmission rebuilder, I can't imagine that there is any need for any kind of expensive tool from the big truck. The cheapest $8 variant will outlive you and work just as well as the one that costs $100.

According to Mercedes use a suitable screwdriver. Or use Lisle 56750 Seal Puller.

Properly applied pry bar is great for axle seals as well.

Careful use of an aligning bar/crowbar/rolling head prybar works well too with the angled end.

I have used a Snap on cotter pin puller to remove seals, pilot bearings and numerous other applications for 50 years. Never pulled a cotter pin with it.

I use a Lisle, picked up on clearance from Sears (probably a packaging change), paid with points, so it was almost free for me. Before that I used a screwdriver.

I use a lisle puller as well, but as oldmachinenut alluded to, before you go putting force on it, make sure youre between the seal and the case and not one or the other.

Thanks guys

Unfortunately there wasn't too much choice locally, so I've bought a case/housing ruining tool haha!

Not too keen on it, but I'll see how it performs. The Lisle looks good though! I think I'll get one of those ordered.

Also found this slide hammer set which sounds like a good investment - anyone ever used this style and can recommend / suggest I avoid it?

Snap on make a great set, item no. SPS2. The level is the pin (2 different lengths) so they dont damage the casing.

I assume you're in the UK? I have a slide hammer from cromwell that i use for seals when i can get it in, its a fork type instead of the collet type which i find work much better on softer items like a rubber seal.

I use a rigid style seal puller. Or a set of heal bars when needed. No big truck brand, just run of the mill.

I have a small slide hammer that one can put a sheet metal screw into the end of. Pop a hole in the metal portion of the seal with a punch or awl, screw in the puller, and a couple of yanks and the seal is out.

Thanks Rich - I've found the Snap-On SPS2 set but from looking at it won't the pin straddle the seal and prevent it from lifting up? As you'll be pushing down on the pin.

Afraid I can't find the fork type version from Cromwell

My method is very similar to this. I just carefully drill about a 1/8 hole in the seal, then use the 90 degree end of a machinist scribe in the drilled hole. A pair of vice grips works as the slide hammer.

Sort of, it tends to just bend the seal slightly meaning it pops straight out, or as you pry it back, the pin slides down the seal as it pulls it from the top, maybe it wouldn't work with more rigid steel bonded seals, but your typical rotary shaft seal it works great.

Diddnt realize cromwell had a new website which im not a fan of at all, but this is the kit;

Most of the time I can get in with a screwdriver there are some instances where the puller with anvil built in helps with stubborn seals or tight clearances

This is my tool of choice. And I'll be honest, I didn't know that it was meant for cotter pins until now.

Just an update for you guys; the 'case/housing ruining tool' worked a treat when used while watching out for damage to the casing, but I think I'll invest in the Lisle tool and possibly the Snap On tool too for future jobs.

Thanks for all the help!
