stagcar Posted November 14, 2009 Share Posted November 14, 2009 Hi All, I have just come to remove the rear break drums and they are rusted on! I have sprayed WD40 everywhere and left it for some weeks allso hit with large hammer still to no avail Its not stuck on the breaks its just rusted on the end of the drive shaft Any ideas? or is it time to cut them off with the grinder? Thanks Derek Quote Link to comment Share on other sites More sharing options...
Rab Posted November 14, 2009 Share Posted November 14, 2009 Sometimes a small lip can be on drum between shoe and outer edge stopping removal. If shoes are fully backed off and drum is stubborn to move forward and off I do: 1.Make sure rear of drum to back plate is clear rust/damage 2.Would also soak WD and if self adjusting drums on place some internal side through adjuster hole, would also soak with awe tad diesel as is a great penatrator. 3.A good rubber mallet or baw pain but be carefull when hitting drum as can shatter/crack 4.Sometimes awe tad heat added to drum will let it pop off when hitting with awe hammer / hit and turn drum at same time. 5. Awe smaw drop copper slip on rear owe drum helps stop things sticking. 6. Also at times you may find the shoes will move forward and slightly jam the drum removal also. 7. GRINDER WOULD BI MI VERY LAST RESORT Quote Link to comment Share on other sites More sharing options...
steveopel Posted November 15, 2009 Share Posted November 15, 2009 If its not moving at all and you are sure they are not catching on the shoes knock some wedges in around the gap at the back between the drum and the back plate chisels normally work just so it puts a little pressure on it to push it off then get the mallet out and knock around the centre that normally works if it doesnt a bit of heat and as Rab says grinder is last resort.

cam.in.head Posted November 15, 2009 Share Posted November 15, 2009 ive had this many times as im sure many owners will also. the centre of the drum can be a tight fit on the axle shaft . a good clout with a heavy hammer on the FRONT FACE of the drum at the OUTER edge has never failed me yet !

keith1200 Posted November 15, 2009 Share Posted November 15, 2009 Might seem like a silly question! Can you rotate the hub? If so, follow the advice above. As for grinding off? I've heard of cars sitting about (never moved) for years and I've never heard of anyone grinding off hubs! i'm not saying it hasn't been done before, it's just VERY rare. If you still can't get them off? get a set off 'fresh eyes' to have a look? weetabixs might help also GL Keith Quote Link to comment Share on other sites More sharing options...

stagcar Posted November 18, 2009 Author Share Posted November 18, 2009 Blow torch and BFO hammer. Works a charm. Hi all Thanks for all the great responses Yep its stuck on the canter of the drive shaft for sure the drum rotates free and it not binding on the shoes I will try the get it hot and hit it with a big hammer trick weekend Thanks again Derek Quote Link to comment Share on other sites More sharing options...
mantadoc Posted November 18, 2009 Share Posted November 18, 2009 I've never heard of anyone grinding off hubs! Still haven't, it's drums. I made this: To do this: Without damaging back plates. I should have just ground the corner off the disk top hat near the front face, then I would have been able to get it off without bending the auto adjusters by pulling the front off the drive shaft then releasing the shoe retaining springs. Curiously I've rarely had drums stick on solid (this axle sat outside for 7 years) except for those that weren't original drums. Quote Link to comment Share on other sites More sharing options...

cam.in.head Posted November 20, 2009 Share Posted November 20, 2009 Yep thats the way to do it always worked for me too! hi crazydave. yep never failed me yet. pulling them from the back just seems to make them even tighter. one big hammer one clout hey presto !!!

mantadoc Posted November 20, 2009 Share Posted November 20, 2009 pulling them from the back just seems to make them even tighter. That does seem to be the case. However, sometimes yoiu have to acknowledge that if the original poster has soaked it and thumped it that they already have probably covered thumping it every which way before asking at which point you need other options.

Julian Posted November 20, 2009 Share Posted November 20, 2009 (edited) I had this problem with my Manta twenty odd years ago, and believe it was caused by over tightening the wheel nuts with an air wrench, not by myself, may I add!! I might be wrong but by dogging the wheel nuts up in that fashion, you acctually spread the metal of the drum so that it reduces the diameter of the hole in the centre, causing it to tighten up against the axle half shaft, so when you do eventually drag them off make sure you run a file around the iside of hole, so that when you put the drum back on it has enough clearence to slide over the axle shaft. Some commercial vehicles have a couple of tapped holes in the face of the drum so that you can screw a bolt into them and push the drum off, I rest my case!!

keith1200 Posted November 20, 2009 Share Posted November 20, 2009 I'm nah going tae lick up your butt coz I ken your brilliant (pun) Seriously? first time I've seen a Scissor-jack being put to good use stagcar? everyone has different 'skill' abilities, I assumed, when you mentioned 'grinding' it off, you didn't know much about Mantas. I use my Manta regularly and still, I've wasted 10-15 mins [june past] on moving the hubs drums. As posted above, give them a good 'f**king' kick-in/hammering mind put the wheel nuts back on first (protect-threads) and watch the cars body work.

mantadoc Posted November 20, 2009 Share Posted November 20, 2009 LOL And then another jack (similar to a Manta jack) had the top cut off, add some studding and use to pull half shafts Making good use of the things that I find since 1976 Quote Link to comment Share on other sites More sharing options...

mantadoc Posted November 20, 2009 Share Posted November 20, 2009 EDIT, love the hammer, what did you add it to the second pic for? The thin one in the blue rope? Wound it up in the rope to tighten it as these were so tight I had to do that to stop the puller jaws slipping off. Quote Link to comment Share on other sites More sharing options...
pat Posted November 20, 2009 Share Posted November 20, 2009 (edited) only a guess kev but i would say the hammer was used to tighten a improvised torniquet (not sure thats spelt right)with a loop to locate it when tight enough to locate the claws on the drum edit beaten to it as always Edited November 20, 2009 by pat Quote Link to comment Share on other sites More sharing options...

pat Posted November 20, 2009 Share Posted November 20, 2009 no , think it may be a faulty drive , but the other 2 spares i have are apparantly now unstable as they just bluescreen the bugger , still it was fun trying. if fun usually involves swearing regularly , Oh course it does its a car forum Quote Link to comment Share on other sites More sharing options...
mantadoc Posted November 20, 2009 Share Posted November 20, 2009 slave your drives into another box and scan disk them, use the attempt recovery of bad sectors option. Although depending on your OS you can trugger setup to pile stuff onto the slaved in drive, pop it in the other box and let it complete install in there Quote Link to comment Share on other sites More sharing options...

I have managed to get the bugger of in one bit without using the grinder LOL Looks like i was wimping on the hammer so a club hammer and a few good swings got it on the move Cheers again Derek Quote Link to comment Share on other sites More sharing options...
