Maverik Posted May 1, 2014 Share Posted May 1, 2014 Hi folks, trying to remove a spigot bush from a 200tdi crank... I've done a fair bit of searching and the common method seems to be the "hydraulic" way, or using grease a suitable plunger and a big hammer... OK, I've tried this method and managed to trash a socket extension bar due to the thwacking I've given it and the bush hasn't moved a mm... Gave the flange a bit of heat didn't seem to make much difference. I was considering some freezing spray, or just trying to cut a careful slot in it and pull it out... Main question is how much abuse can I give the end of the crank, I was acutely aware I was bashing a shaft with quite tightly toleranced bearings!!! so maybe I wasn't hitting it hard enough, but to be honest I would be rather uncomfortable hitting it harder than I have already... and I hope I've not done any internal damage to the main bearings... So has anyone got any advice at all? Cheers Mav Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted May 1, 2014 Share Posted May 1, 2014 i've always used the grease method... Apart from mine which pulled out with my index finger. You need to pack the hole with grease and use something with a very snug fit. I use my clutch alignment tool, but thats something i made on a lathe at work. 1 Quote Link to comment Share on other sites More sharing options...
Boydie Posted May 1, 2014 Share Posted May 1, 2014 Agreed, the plunger needs to be a very snug fit, no more then 0.01" under the diameter of the bearing, ideally made out of brass, pack the end of the crank with grease apart from say 1/4" to allow entry of the plunger then give it a very hard couple of whacks, the spigot will come free. If it doesnt then the only resort is a very small die grinder and split the bush. 1 Quote Link to comment Share on other sites More sharing options...
reb78 Posted May 1, 2014 Share Posted May 1, 2014 I found something that was close, but not tight enough to do the hydraulic method. Could have been an old socket extension. I roughed up the edges with a punch, all in one direction and then inserted it into the bush, when turned, the rough bits dug into the bush and enabled me to pull the bush out. Didn't matter that it was damaged since i was replacing it. (don't know if that's described particularly well, but hopefully makes sense. edit to add - the last two i removed pulled out with easily by hand. Not always that easy though!

MuddyWinny Posted May 1, 2014 Share Posted May 1, 2014 Admittedly it wasn't a Landrover but when a friend helped me change the clutch on my car we extracted the spigot bearing/bush with a slide hammer. Quote Link to comment Share on other sites More sharing options...
Mo Murphy Posted May 1, 2014 Share Posted May 1, 2014 The last one that I changed was so stuck that I had to cut a slot in the bearing with a sharp chisel to get it out. Mo Quote Link to comment Share on other sites More sharing options...
Maverik Posted May 1, 2014 Author Share Posted May 1, 2014 Thanks for the advice, I'll try tighten up my "piston" fitting, but also had an idea of using a pipe expander tool and a reverse hammer... will let you know how I get on... still rather wary of thumping the crank...

Tanuki Posted May 1, 2014 Share Posted May 1, 2014 I usually do them with a slide-hammer and the very small 'internal' 3-leg bearing-puller supplied with the slide-hammer for just this purpose. Much less-messy than all that buggering about with grease which inevitably gets itself on the face of the flywheel and/or in your hair when it shoots out unexpectedly.. 1 Quote Link to comment Share on other sites More sharing options...

CwazyWabbit Posted May 1, 2014 Share Posted May 1, 2014 I've also seen people use a slice or two of bread instead of the grease! That may well be less fussy about the tolerance of the fitting of the piston. Admittedly this isn't a land rover but it's cleaner than grease Quote Link to comment Share on other sites More sharing options...
Yostumpy Posted May 1, 2014 Share Posted May 1, 2014 I suppose you could 'Dremmel' it out if all else fails. Good that your changing it tho, Had my clutch changed and they didn't change the bush, 'squealed like a pig' Funny really as it didn't squeal before. Anyway I 'persuaded' them that it should have been done , and they took it all out again and swapped the bush for no extra charge.I think I was very lucky.

dirtyninety Posted May 1, 2014 Share Posted May 1, 2014 I've generally just pulled them out with my finger, but if i couldn't I'd use a carbide bur in a die grinder. Carbide burs are useful for just about anything, grinding nuts and bolts off manifolds and starter motors saves a HUGE amount of time.

Jon White Posted May 1, 2014 Share Posted May 1, 2014 Pack it with grease, and grab a 1/2" drive socket extension. Then wind insulating tape around the extension until its a nice tight fit in the bush, thena couple of taps with a hammer and out she pops!

Briarston Posted May 1, 2014 Share Posted May 1, 2014 Another way that has been mentioned from time to time is to use a suitable size (thread) tap, with a ball bearing or other spacer in the bottom of the spigot bush hole. When the tap meets the spacer keep turning and the now threaded bush is wound up the tap. However, the grease method has always worked for me.

greenstream Posted May 2, 2014 Share Posted May 2, 2014 Hi Instead of using grease, try soaking page of old newspaper in water and use these as press material. And of course a socket, this doesnt have be super tight due to the texture of the wet paper. Quote Link to comment Share on other sites More sharing options...
Maverik Posted May 2, 2014 Author Share Posted May 2, 2014 Hmm I have a feeling that this bush may be stuck a little harder than most... the inside of the bell housing was full of guff from a leaking rear oil seal and a leaking clutch slave cylinder the bush looks old and worn, I really don't want to damage this engine by thumping it, so going to cut it out...

ajh Posted May 2, 2014 Share Posted May 2, 2014 You can also fragment them to get them out. Bronze is fairly brittle. Quote Link to comment Share on other sites More sharing options...
101sean Posted May 2, 2014 Share Posted May 2, 2014 Broke the one up in my lightweight with a fine centre punch without damaging the crank. Quote Link to comment Share on other sites More sharing options...
Maverik Posted May 2, 2014 Author Share Posted May 2, 2014 Broke the one up in my lightweight with a fine centre punch without damaging the crank. hmm interesting didn;t think of this, might give it a go... thanks again for the idea's!

CwazyWabbit Posted May 2, 2014 Share Posted May 2, 2014 Seems a sensible enough idea, especially when you think how easily they can be damaged when putting them in. Quote Link to comment Share on other sites More sharing options...
fenflyer Posted July 25, 2015 Share Posted July 25, 2015 I've just changed the spigot bush on my 200tdi used the bread method took some persuading but coame out clean, my question is once the new one is fitted does it need any lubrication before fitting gearbox?

discomikey Posted July 25, 2015 Share Posted July 25, 2015 that bread trick is incredible! definately trying that one next time i have my gearbox out! Quote Link to comment Share on other sites More sharing options...
vulcan bomber Posted July 25, 2015 Share Posted July 25, 2015 Bronze is used because it's self lubricating, similar to cast iron... I usually put a very light smear of grease on the gearbox input shaft but it should be fine without it. Quote Link to comment Share on other sites More sharing options...
Maverik Posted July 25, 2015 Author Share Posted July 25, 2015 I put a liberal blob of copper slip in there. After a good bit of thinking about it that is. Came to the conclusion it wouldn't do any harm. There's a clever reverse bevel cut into the flywheel centre to stop oilyness from being flung onto the friction surface.

Snagger Posted July 26, 2015 Share Posted July 26, 2015 I used a hammer and sharp chisel to cut a slot, allowing it to slide right out by finger. It maade a very light score ont he crank, the raised burr I removed with a round file - the slight score doesn't do any harm as it's hair thin and it's not a bearing surface. Freeze the new bush before drifting it in. Quote Link to comment Share on other sites More sharing options...
