brake backing plate - how to remove?
Hi,
I am STILL trying to get my dam english axle apart to replace the diff. The problem I have now is the brake backing plate is preventing me from using
THIS method with the two bolts rather than bashing a wheel:

in use
That is NOT a picture of my set up, I can't do that as there is a brake backing plate with all the brake shoes etc on it - if I could move the
backing plate I could do it, but I can't figure out how to get it off - well not without cutting it up anyway!

Put a wheel on and hit the tyre not the wheel pulling at the opposite site at the same time.

hammer two wheel studs out and replace them with threaded bar. A nut fitted on the inside will allow you to wind the bar down against the back plate
and force the bearing out.

Or you could use the correct piece of kit called a Slide Hammer.
Slips over two opposing wheel studs and the nuts are done up tight. A heavy round hammer is then slid along a shaft (which is attached to the bracket
attached to the studs) against a reaction stop. This pulls the shaft out an absolute doddle.
Beware of the Goldfish in the tulip mines. The ONLY defence against them is smoking peanut butter sandwiches.

 the cost!  personally I don't like inpacting bearings anyway as the cages can be damaged...

Anotyher vote for the slide hammer. It took me about 3 mins to remove both of my shafts.

a slide hammer is find if a) you have one and b) you ensure chassis is supported porpely so no risk of pulling it off the stand.
I recognise that photo and it was my first attempt at removing the 0.5 shafts in order to fit back plate.
After SVA and some driving I had an oil leak on passenger side so had removed 0.5 shaft again and the back plate was fitted so it is possible to do
using those "tools".
added.
when you remove the 4 bolts for the flange which alos keep the back plate in place (?) I used a smaller set of bolts to "hang" the plate
so that a) the pipe is not stressed and b) it does not get in the way.
can't remember all the detials but it wasn't that hard to do. I have 8 inch drums so if you have 9 inch, maybe that makes is harder?

How long is a slide hammer? I only have limited room each side of the car, not sure it will fit....
Pics!

Yeah, I did have the clearance fun. Had to move the car on the jack in between sides!
As fro pulling it off the axle stands - no way! It took a lot less of a tug then I expected. Nowhere near enough to pull the car off its supports.
Trying the wheel/tyre method, I found it nearly impossible (although worked for putting them back in).

I should change this into a "WANTED, SLIDE HAMMER" thread
Cheers fellas!

You don't need a slide hammer just a 2kg mash hammer you don't need to bash hell out it -- just ensure you work the hammer blows round
the clock and pull opposite where you are hitting -- normally 3 blows on the tyre is enough.
The way it situated next to a wall you won't get the shaft out anyway.

The problem with the tyre/bashing technique is the angle of pull. As you smack it, you are not pulling straight out, hence it will take more fouce
than pulling at the midpoint. If you use the correct tool for the job (I know, the 'adjustment' hammer is a very handy tool!) it makes
life so much easier.
If you have some steel, a welder, some threaded bar etc kicking around, you can make one pretty easily, although I just borrowed one from my local
garage!

Why? its the proper tool for the job! will cause less damage than most other methods
PS Where abouts are you Dangle_KT ? Perhaps someone in your area may be able to help.

When hitting the tyre its the pulling on the opposite side that actually pulls the shaft out, the blow to the tyre just wiggles the bearing a tiny
bit.
For anyone trying this hitting the wheel rim is actually less effective, than hitting the tyre because the impulse imparted by hitting the tyre is
an elastic collision -- the force imparted is lower but last longer.

I have a slide hammer in North London if that helps.

As BT says - How long are the half shafts? How close to the wall are you? Might be worth sticking it back on wheels and doing job outside at weekend
(if its dry enough).
