After purchasing 4 new drums I realised that they come with only one countersunk fixing hole.
Where as the old one had three.
Is this the normal now only one fixing point.
Yes the wheel will hold everything together once assembled.
Do I get drilled out or not.
Your thoughts would be welcome.
Cheers.

That's interesting. 3 will centre the drum on the hub.
With only 1, I'd want to put it on loose, adjust the brakes to touching and spin a few times to centralise then tighten the wheel nuts to keep in place

Hadn't thought about centreing the drum. And yes it could make all the difference between having good or poor breaks. I'm now considering having the new drums machined for 3 securing holes. Cheers, that's good advice thank you.

They won't be far out, but i expect if not centered then it will be similar to old and worn out drums and a pulsing pedal

You only need 1 hole. It’s a retaining screw so drum does not fall off when you remove the wheel.
Drum don’t need centring as the wheel studs do this

Does the drum not fit on a spigot?
I think Phil is correct ref screw to stop drum coming away when wheel removed.

kermit_rr · Aug 23, 2023

all the ones i see online have 3 holes, plus wheel studs
there was an additional screw hole to aid removal

2 retaining screws on ours. Plus a threaded hole for drum removal, as above^^^^^^.

All the heaps I’ve had (not all landrovers) have only ever had one retaining screw.
They can’t go anywhere once slid over the wheel studs. Specially with five.

The screws are to hold the drum on whilst on assembly line the third is so you can use a screw to help ease the drum off as the hub is threaded but the hub isnt but to be honest are not needed...

Only if the hub seals don't leak

Thank you all for your advice. I'll run with just the one retainer screw.
Thanks again.

If the hub seal leaks onto the drum then it won't rust solid after years of neglect

I have an old spade bit ground into a big effing screwdriver just for such a job.

I broke so many drums removing them before I figured it out. At least two.

Anyway:

Undo the screws, by whatever means.

Screw into the threaded hole.

Tighten.

Slack off the adjusters

Tap the drum with a decent hammer all the way around. Repeat until removed. Slowly, slowly, catchy monkey.

Check your replacements, two years ago I bought a pair [on line] for my Ninety rear [same as series]
They were not round

They were returned, a good set were just a few pounds more.
