5 speed manual or LT77S ?

if its the same as the bit I think your thinking of in the LT77 that I had to last do a recuild on I used a 2 leg puller and then with a pin torch (very small oxy torch essentially) heated the bits of the ring that werent held by the puller to red heat while someone else gingerly applied torque to the puller arm (bout 1/6th of a turn at a time) and then smaked the lifting screw with a brass head hammer.

you can also slice it with a dremel if youve the patients and the old smack it with a chisel trick that you can use on ford wheel bearings works a treat as well (I special ground a chisel for this job)

Thanks all for your help, I bought a 10 ton Hyd. puller and bearing splitter set(old one was a 5 tonner) off ebay this arvo for $187.00 (delivered), local tool places wanted $350, repco $600, same kit same brand, christ some of these mobs have some mark/up, will have puller by mid next week so should be able to get box apart then, if not I will paint it green and throw it into the long grass down the back paddock.
Any sugestions on where I can buy Gaskets, seals, bearings and "That" rear seal collar, Regards Frank.

Im pretty sure that the last lot I got came thanks to Tim at landrovers only and he sourced some out of fourwheel drives in melbourne.

I did exactly that for 5th gear - neighbour with his torch, but as I applied pressure with the puller and home made adapter I was using high velocity blows with a very light hammer and punch on the rebated face of the gear. The vibration was what got the movement.

It's going to be fun getting it back on!

I found the guys at Karcraft EXTREMELY helpful. The big box of parts (including gaskets) shown in my pics came from them. They had all parts in hand and the freight was next day.

My new 10 tonne puller should be here mid week, I was going to pull this box right down as I was told it was seized, it had been out in the open for a couple of years. The oil had plenty of water in the 5th gear section but next to none in the main. Turns out the box was jammed in 2 gears at once, once I rectified this the box turns over nicely, can't see any rusty gears in the main box, so I will give it a good flush out and just pull the back cover off to replace the buggered (now) seal collar and check out the oil pump gears and flush the oil ways.
Thanks again for all your help, hope I can reciprocate someday, Regards Frank.
