Daf 44 : Don't have the right puller...

[deskjockey]

Darn! The kloggy kart showed some rear-end braking imbalance during MOT. The guy told me it may cause a fail next time.

One of the drums came off easily. I was able to clean the shoes and cylinders, but on the other side the drum is stuck to the shaft (by rust presumably).

I've been looking around for a puller that attaches to the drum's wheel studs, but the only model I could find does not fit, one of the stud cannot be inserted in its puller's slot (when the two others are in position) and the central pushscrew ends up off-centre and cannot push in line with the driveshaft.

I brought it back and got a refund.

Anyone knows of a trick, or a way to rig something to pull off that drum?

I made that mistake! Eventually I bought one from Machinemart, which is great! I still have it & have used it to take the drums off my 33 (when I had one...) and other brakes, too.

Try t'internet (...a Yorkshire goal!) for the company & see where your nearest branch is.

[Nick the man with a daf....]

you tried giving it a tap with a hammer I presume???

[deskjockey]

I mostly tried the following, with the wheel bolted to the drum lugs:

From under the jacked-up car I wedged a steel bar against the inside of the wheel rim as close as possible to the drum and hit the other end with a hammer in an attempt to pop the whole assembly out.

Apart from loud noises I did not get any results.

I did not try hitting the drum or the shaft from the outside (I don't think banging the shaft would do any good to the threads or the reduction gearbox)...

Silly question but did you remember to slacken the brake adjusters first?

[deskjockey]

The drum could spin freely so I think there was no interference from the brake...

[pauldaf44]

Sorry did I read right that the drum will spin freely on the rear wheel of a 44? Thats not good you shouldn't be able to turn it easily without both wheels off the ground and someone turning the other. If it will spin freely otherwise then you have a broken half shaft or belt.

[deskjockey]

You're right, I should clarify. Everything (from drum to belt pulley) spins freely when both wheels are off the floor. The shaft is fine, I use the car almost daily.

What I meant is there is no interference within the brake. The drum is rusted on and I don't like the idea of using heat to unstick it (and possibly damaging the bearings/seals).

As you're in France I suppose popping round to north London to borrow my puller is a bit much.....

Funny you should say that. I'll be in Manchester for three days this week, but I don't think I can talk my boss into paying for a mission extension so I can drive down to London...

ive got a slide hammer which bolts onto the drum its really good,

[deskjockey]

Hey, maybe I can make something along the same lines, but simpler.

A thick metal disc with holes for the studs and a spacer in the center to press on the end of the driveshaft.

Screwing the wheel nuts down onto the disc may give enough force to pull the drum... as long as all nuts are carefully given the same number of turns.

Gotta try that, maybe next weekend.

Thanks for the pic.

I used a cheap 3-leg puller and never had problems with it. You may need to grind or file the ends slightly so they'll fit between the flange on the drum and the backplate. Tighten up firmly (but not stupidly) and then hit the centre of the puller with a hammer. The aim is to loosen it with the shock, not by brute pulling force.

I've also used the same puller in conjunction with some rope for piston pin removal and re-fitting - best £3.50 I've spent in a long time ;D
