Spigot bearing removal (Done!)
MautoK - 12/6/09 at 04:35 PM

L&G,
I have a 'new-to-me' Pinto 2L replacement and am converting it from manual to automatic. Clutch & flywheel are off and I now need to remove the spigot bearing. The torque converter has a 3/4" dia spigot that engages in the spigot bearing hole.
I have a piece of wood dowel that's a nice snug fit in the ID and have tried packing it with grease to hydraulic it out, but it's not budging.
Do I persevere or take the destructive approach and lever it out?
Thanks,
John.

Use a universal fitting tool (hammer!) in conjunction with a drift to apply some power to your lever - but be careful.

Tom,
Yes, I'm whacking the dowel with a hammer but the bearing is not interested...!

Try window putty instead of grease, it's thicker and tends to stay put better.

Good thinking, that man!
I'll try that (if my pot of putty is still workable...)

Conspiracy of tolerances is at work!
It's become an un-reuseable bearing now; the needles are out and I tried to collapse the outer race but it won't play.

I don't have a grinder small enough to get in there, so going to try making a puller with two six inch nails, flats filed on each head so they'll lock in behind the inner rim. Then either a long bar welded to the nails' pointy ends to make a slide hammer or a lever arrangement might do it.... We'll see!

Any other ideas?

I used a dremmel with a small grind stone
to grind through a narrow section of the side wall.It worked a treat.

Slide hammer!!!

Use a suitably sized Rawl bolt in the hole with a LARGE thick washer. When thew rawl bolt is tightened you can then lever against the washer and hey presto out it pops as easy as pie.

Total cost of this low cost tool - about £3 tops.

The other option is a small cold chisel to break the outer race.

All the ones I have done have come out either with grease or a bolt hooked on the inside and used like a slide hammer.

When all else fails, the tiny cold chisel bought for this job.

hahaha I replaced one of these this week, crossflow but same principle.

I tried the drift technique - fitted an aluminium tube onto a drift so it is a snug fit, filled up with grease and introduce mr hammer.

no budging, could I get the drift out? could I f***. there I was, with probably was was a good bearing not knacked with a hardened steel drift poking out the end.

let's say I was not a happy buuny.

fortunatley with some side to sdie movent got the drift out and this time introduce mr dremel with small grinding disc.

about 5 - 10 mins managed to grind through the race enough to collapse it and using a samll chisel, poke it out.

trhing to crack the race with a chisel resulted in denting the chisel - grind it out is my recommendation.

I didthink of getting a rawl bolt - you know the expanding cone type and then rigging up something that I could hammer but didn't - that may have worked. (that method was successful in removing the piston from a sierra master).

Your chisel obviously wasnt man enough for the job then

A well placed clout with a small cold chisel will invariably crack the race with all but minor damage to the chisel. (Obviously some damage will occur as a bearing race is ~60Rc)

Bit of weld on the inside of the bearing race will cause it to distort and shrink, should just drop out then.

I do tend to get rather "medieval" on these things - never had one pop out by the grease method yet; always had to resort to a good chisel.

I have many success stories with the rawl bolt/slide hammer trick, but needs a big slide hammer to work..

I did it this way on my 4AGE much cleaner than the grease method! I bought some threaded rod a rawl bolt a couple of nuts and washers. At the other end I had a lump of metal I could slide up and down the threaded rod to make a slide hammer.

I don't deny it - it is a tiny chisel, maybe the thickness of a pencil that I manageto bend!!!

Well it's out!
Bought a Dremel this morning; a rather non-locost solution, but at least I've retained my sanity.

I've swapped all the external bits to the 'new-to-me' engine and adjusted the valve clearances.
The great spline god was not in a friendly mood and it took 30 minutes to get the auto box attached. Is it just me, or do you find that either it goes straight on first try or it takes about 100 attempts?
So now the (replacement) engine and (recent replacement) autobox are back in the car.
Tomorrow, connect everything back together, make sure there's oil pressure, do a compression test for reference then turn the key...
John.
