Hi Guys, I'm after a little bit of help removing a rear brake drum on a 1983 110. Drum is spinning freely and not stuck on the shoes and the retaining screw out so I'm assuming it's stuck on the plate beneath. I've tried whacking it with a hammer on the face but no luck. Does any body know what size the threaded hole is that pushes it off the plate? I've seen on here someone thinks it 5/16unc but that seems a little small. The hole will take an 8mm bolt quite easily, so looking at something around 9 - 9.5mm. So before I order anything are there any suggestions from you lot? Thanks
 
Is it definitely stuck? no movement at all between that and the hub? I mean I'm not an expert but having done mine recently I'd just be beating it with a hammer on the sides of the drum. I don't think you're supposed to as I imagine they could crack being cast but if there's few other options I'd do that and possibly have to buy new drums.... It doesn't seem like the cost of a pair of 11" drums is the end of the world, £60-70.

I actually feel like I maybe should've replaced mine when I did the shoes, but there wasn't much of a lip so just shoved the old ones back on.
 
Spray some release oil like Plus gas or RP 90 [ even some diesel ] on the wheel studs where the pass through the drum and whack it some more on the rear edge knocking for out. A lump hammer that has a wide face is best.
 
I feel your pain, one of the reasons I fitted a disc braked axle to my 85 110.
I used 2 large flat bladed screwdrivers behind the drum 180deg apart and put pressure on them (probably need another pair of hands) then smacked the outside of the drum with a heavy copper mallet I've got, rotating the drum every 5 whacks or so. You are levering against the back plate but they are quite sturdy.
 
I have never really had a problem getting the drum off the Ninety. Mind you it's usually because the hub seal has leaked and it's covered in oil anyway.

Funny you should say that. The other side came off without a problem and yes, the hub seal is leaking also.

I have been looking at discs but still trying to save the the pennies at the moment.

Yeah I know its not a huge cost and a no brained if I was paying someone by the hour to fix it. £70 would just about get uoj an hours labour.

I have sprayed everywhere I can and now I've got it off. The answer was staring me in the face, it was a sledge leaning up in the corner of the garage and a couple of blow torches. And a couple of whacks and it was loose
 
Thank you to everyone for your replies. It's now off. A combination of 2 blow torches and a larger hammer(sledge) and couple of well placed whacks on the face broke it free.
This is exactly what I've been finding out on my 110 so far... There is no such thing as an easy/quick job, every job is a struggle and becomes a bigger task than it should be :rolleyes:

Although mines a 1988 and been heavily waxoiled in the past, I imagine it's better to work on that some of the rustier examples!
 
When Mr Haynes says tap gently with a soft faced mallet, usually means knock seven shades out of it with the finesse of someone with sledge hammer tourette's

Mr Haynes probably also had the luxury of a nice warm workshop equiped with all the tools required, someone taking photos and someone making tea. Not like me, working outside in the p*swing rain and sitting in a puddle.
