“Stay turned for part two, where I saw off the prop-shaft bolts to get the drum out!”
Well some more thought made me realise that the bolts weren’t the problem, the shoes and other gubbins inside the drum were the problem. A number of suggestions from various forums and mailing lists included partly dropping the gearbox, cutting part of the floor away, and cutting the drum apart.
I decided that dropping the gearbox was the easiest way, but it would only move about 1/4″ before the gearbox hit the cross member below it. To be honest, I think it pretty much dropped vertically, compressing the engine mountings on the way. The next step was to slacken the handbrake adjuster as far as possible to minimise the shoe spacing. This didn’t give me enough clearance to get the drum off, but I could get enough clearance to start attacking the innards of the drum with a selection of screwdrivers and long nosed pliers.
After a certain amout of brute force and ignorance, I was finally able to pull the drum and shoes off together.
The spring that runs fore and aft at the top of the drum caused a little consternation for a while, and I came close to dropping the whole thing on my head when it finally came loose!
I’m also firmly of the opinion that it took sweat (it was hot on Saturday) tears (dust in my eyes, not frustration, though it was a close thing), and blood (when I caught my thumb between the drum and backing plate) in that order to appease the gods of Land Rover maintenance.
But it’s off, I’ve test fitted the X-Brake, and it’s starting to get dark so I’m off to get a celebratory take-away. I might need to whip it out again and just trim a few mm off the top of the lever (on X-Eng’sadvice) to get enough operating clearance.
Thanks to all who offered suggestions and assistance. I just need to order some bits and pieces since I want to replace some worn bolts on the way, and bolt it all back together. Oh, and I need a bigger spanner to do up the M16 bolts on the X-Brake – the largest spanner I have is 22mm, and these are 24mm.
