Big F***ing hammer will work, to get an inner race off a 8 3/4" axle? Or, is this just me rantin', again? :blah:

Axle leak, mostly outer seal. :mad: Went out, bought a 'good' bearing splitter for $48. Set up a puller, and bent the dang tool bolt!
Get to hunt down someone, with a tough enough press, hold their mouth right, so on and such...no heat!

Went through this bullshit years ago, via Nappy (correct tool was a cuttin' torch!) Napa headquarters had to find me a good pair of axles, to replace the ones they screwed up.
Wasn't pissed...the hell I wasn't!

Better...
 
I used a cut off wheel and cut most of the way through it and the hit it with a cold chisel and hammer and it came off. Just make sure not to get into the axle like I did. I ended up replacing the axles. But I only over cut one. The other turned out fine. Unlike this guy I cut mine on a 45 degree angle so as not to get into the flange. Also I have a 20 ton harbor freight press so that helped.



Another way

Appreciate that, BeepBeep.
Yeah, thought about that, but not much room to work with. All that's left is the inner race. Even thought about heat flashing it, something I've done many times...then I remember my axles they used the torch on.
When I got 'em back to the shop, and un-wrapped them, blew up. Heat blued, took temper out of the steel, even torch cut one place. Took them back, slammed the axles on the counter, and...
Probably better off, going on the hunt.
 
I ended up buying yukon axles from summit. Sadly I had to cut them to fit length wise. I have a pile of parts that are in my oops pile.. And that pile contains one 440 piston and a 8.75 axle. The Yukon axles were at a decent price.

Thats why I cut them on a 45 so as not to get into the plate. But i miss judged the depth of my cut, and hosed up an axle.
 
I do a 45 degree cut if I can't do a 90. I cut off the outer race and cage, then carefully cut the retainer ring a bit at a time until it cracks with a chisel. Then I cut the inner race carefully, a bit at a time, until it cracks too with a chisel. I usually can R&R a bearing in about 10-15 minutes this way. I use the press to install as you only need to support the bearing and press the axle into it. You just have to be careful not to slip and hit the inner seal area of the axle. Some tape can help prevent this. I used to do this on the bench grinder, but it too a lot longer to grind due to the width of the wheel, and was easier to grind into the axle as you can't easily determine how far you have gone.

Got the inner race off, with a 45 cut.
That's after hearing 4-5 times, only way it would go, was cherry red via a cutting torch! I'll do a LOL here. Load of crap.
Outer seal was main leak, old slipped right out, new seal going in, not so. Way they go in (backwards), hammer, small arbor press, no tango. Dang thing refused to go in. Located a local two man shop (owner actually older than me), good press...could even hold mouth right! Force fit deluxe!

When I'm ready to press new bearing/collar on, know exactly where to go.

Parts houses ain't what they used to be...machine shops wanna charge minimum shop rate $$, for a simple job, right tool. Pita!
 
WOW. Watched that first video. Saw two things...
Think he needed a BIGGER cut-off wheel (ha)...and something about a monkey trying to f**k a football!:p

Yea in the first video he was cutting in straight across and hit the plate. Different strokes for different folks. I only had a propane torch so I could have been there for hours trying to get it hot enough.

Yeah they are.
Spent a bunch of my working life on radial engines...cranks take straight roller bearings, front and rear, torch to get inner races off. But, even that has to be done right. Heated to go back on, too. Chewed one guy, not doing it right...got the race hot, dropped it on the shaft, and walked away. 3-4 steps, and 'clink', where he heated that race, split clean through...a 4" I.D. inner bearing race!
Right way, was to heat 'flash' it, entire surface, and hold yer mouth right!
Halfway through my life, lost my right eye, thanks to a Mopar bearing race, and me being dumb. Hard lessons.
