Removing bronze bushes in remote housing

Post by rolesyboy »

Gents, what is the best weapon to remove and replace the bronze bushes in the remote housing? I have a bearing puller on a slide hammer but it isn't quite deep enough. I cant get a drift on it as the lip isn't pronounce enough (must be recessed?)
Any tips please? Trying to avoid a hacksaw blade and a blunt instrument.
Thanks a lot

I removed mine by getting a 3/8" Alan head bolt. Then I pushed it through the bush from the bottom of the housing. Then I used a spark plug socket and with a washer and a nut I drew it out. You have to, of course use an alan key long enough to stop it turning. Good luck! do the reverse to push it back, DONT hammer it in.

If you can get the next size up coarse thread tapped into it, then, get that sized bolt atatched to your slide hammer, a couple of taps should "shift" it :mrgreen:

I use an old selector shaft out of a remote gearbox with the end machined flat. And then punch them out with a hammer.
Works well.

That's how I've done them.

Does anyone know if there's a bush in the back of the gearbox case that the shift rod runs in or is it just running straight in the case as the bottom end of the shaft does?
Can't find a replacement bush available, only the seal.

Mark I use the minispares rubber suspension cone compressor tool . The thick threaded part of the tool that screws into the rubber cone ( metric ) is a perfect fit to use to drift out the bronze bushes , also it's long enough as well . ... ken

A Friend here uses a stud extractor to remove them, he even has one modified with a long rod welded and replaces them with the engine in car .

I don't follow how a stud extractor can be used here? I must have completely the wrong end of the stick and be picturing a different type. Can somebody enlighten me please?

No worries I have been puzzled by this too. Then thought he might have meant a blind-hole bearing extractor - that's what I'd use at least.

Sorry Oz for putting the spanner in...
needle rollers are never a good idea when you have an assembly that never fully rotates -but instead just a couple of degrees.
Might not be an issue here here, because loads are low - but results of such a design can be seen on many radius arms and wishbones.

Fully aware on needle rollers/rotating shafts.
That is such a low load area that there is no problem, as has be proven over last 20 years and the amount of kits sold.
Other applications you quote have the weight of the car on them.

:oops: you are fully right, sometimes not so good with the english terms..., its not the extractors that slide over the stud, i meant a broken stud/bolt extractor, similar to these ones, it works fine with a welded rod and slide hammer.

I too am a bit confused on why one would use needle bearings on that shaft. Doesn't that shaft go up and down as well as rotate? Isn't a bronze bush ideal for this combination of motions?

If you need a fancy solution wouldn't something like a linear bearing be more appropriate (even though bronze works well)?

Is the shaft a loose fit in the bearing ?
