OTC1122 Bearing Splitter - 1/8" to 2"

I used this splitter to pull thin bushings off a long shaft combined with a 13" puller. Works great!! Well made and tough, no wear after pulling several hundred bushings

Well, I have to entirely change my opinion of these clam shell separator/splitters. And I have to change it for the positive.Initially, I had bought one of the many Chinese-made models and I raged about how badly it failed. Then I bought the highly reputable OTC brand. And it also "failed" to remove the bearing. HOWEVER, I was the problem, not the tool. Specifically, my inexperience using this type of tool was the problem.I had been trying to remove a smallish 1-1/2' diameter bearing AND a small cog that on top of it. I assumed, incorrectly, that the bearing and cog could be pulled off at the same time. Well, I was WRONG. Don't try to pull two things at the same time!One at a time...on the LEFT side of this little motorcycle crankshaft I was working on, the clamshell fit under the cog and Presto!, it pulled right off by using the "crossbar puller" part of the Chinese set I "used and abused."'Course I had to buy the 3/8" long bolts that fit into the OTC. Then, yes, using the crossbar puller that comes with these Chinese set, I proceeded to pull the small bearing off. THAT is how the tool is to be used.Moral of the story: Just because the items to be pulled off a spindle/axle/shaft are "small", don't EVER try to pull two things off a shaft at the same time.Ah, then I began working on the bearing on the RIGHT side. It also had a cog in front of its small bearing but this cog was shaped differently and I could not get the tool under the cog like I did the left one. This cog simply had ZERO space for the clamshell tool to go it. So, I had to resort to using a Dremel tool to cut the cog off, being careful not to cut into the crankshaft's spindle.And then, since the second bearing was now not unimpeded, it pulled right off, just like you would think it should.Also, please know that if you are tightening the clamshell bolts to the point where the bolt strips, you are tightening it WAY to tight. Medium tight is fine. I repeat, just don't try to pull two things off a shaft at the same time!Now, in retrospect, since tightening the clamshell super tight is not necessary, the clamshell made by OTC doesn't need grade 8 bolts after all. Grade 5, what it comes with, is fine.So, I have had to come back to edit my negative review (now positive) because of what I learned along the way. And to this very moment, I don't know if the Chinese clamshell kit set I bought was OK or not. I was simply using the Chinese kit set WRONG, trying to pull two things at the same time.And then I used the OTC one WRONG and it seemed to "fail." All due to MY "operator error."It comes down to this: Put the clamshell on medium tight and use the puller to pull one thing off a shaft at a time. When I used the tool as I was supposed to, I had no problems. But, at the same time, if the clamshell cannot get under a bearing or cog, don't expect it to work...it cannot work miracles. To get the impossible ones off, just get out your Dremel with a small diameter cutting disk - and exercise caution to not harm the spindle.

Works great! You get what you pay for, quality.

i used this for pulling small (35mm) bearings off a small moped crankshaft, and i'm glad i have it because i'll use it for that purpose many more times. seems very strong and the blades are thin enough to grab into tight spaces. i didn't have a puller wide enough to fit in the holes, so i used a large 2-jaw puller and just grabbed onto the splitter, and it worked fine. would probably be easier with an appropriate puller that you can thread into the holes, as long as the threads don't strip out on really stuck bearings. i assume they won't but i can't say.

this a good tool,i used it to remove an old bearing from a hub,it did what i asked and didn't give me any hasslepackaging was good all in all i recommend it,it will make getting old bearings that are stuck on the hubs,very very easy to get off

When you're in a pinch it works great. I've used mine a couple times so far I love it

I'm busy, and you need a puller to use this, so check out my review of the OTC7393 puller that goes with this splitter. You can't go wrong, OTC hasn't failed me for over 30 years. Gotta go finish the paperwork...

Good quality bearing puller, heavy tough grade of steel. But useless without the other half of the set (OTC 7393 or similar), which I had to order from a different seller. Still waiting for that to arrive.
