Oil / Gunk in front drum brake.
By: YorkshireKev Date: June 16, 2019, 11:01 am
---------------------------------------------------------
Just replacing the brake shoes on my Series 2a and found the
front nearside drum to be full of oil / sludge. I don't think
it's brake fluid, smells like ep90 anyway.
I figure it'll need the hub oil seal replacing. I've not done
these before so was wondering if I'm going to need to replace
any other seals or gaskets while I'm in there. I have
freewheeling hubs too, dunno if that complicates anything?
Any tips or advice muchly appreciated.
Cheers,
Kev.

Series 2 or 3?
If it's a 2, replace the land as well (the bit the seal runs on)
as it's cheap and easily replaced.
Also check your axle breather isn't blocked!
As the axle warms up, pressure is normally released through the
breather - if that's blocked it can force oil out through a hub
seal!
If blocked, clean it out with Diesel/paraffin or similar, or
replace it with an extended breather to prevent future problems.
It's worth getting a new, thick, hub gasket.

Thanks Robin. I'll check out the breather and makes sure i pick
up a hub gasket too. One thing im unsure about is the land? I
cant find any reference on fleebay or paddocks. Is it also known
by another name? My landy Is a 1966 2a with free wheeling hubs,
so dont know if relevant. Cheers, Kev.

Yes, sorry Kev, that's an old fashioned term for a Stub Axle
Collar, or Stub Axle Oil Seal Runner, or Stub Axle Hub Seal
Runner, or Stub Axle Distance Piece, depending on which site you
look at!
Part number is 599698, Paddocks have it HERE

They can be a bit of a bummer to get off though! Some people
drill them and split them with a chisel, I ground grooves in
mine with a grinder and then used mini crow bars to get them
shifted (Japanese 'cats paws' to be precise) then got underneath
once a gap opened up.
Likewise fitting the new one, if you damage it getting it on,
you are back to square one with leaks! Some people use a bit of
sealant behind them, some don't. You can warm it up to expand it
so it slides on easily and then stays in place.
As they are cheap and it is your first time, it might be worth
ordering more than you need!

Thanks everyone. I got the job done yesterday. It wasnt as hard
as i thought it was going to be, but i think i got lucky with
the land/collar thingy. What worked for me in the end was to
chisel a groove on the side then knock it round working it off
the shaft. After a ckean up the new one tapped on slowly but
quite easily.
Cheers,
Kev
