Gearbox mounts - Life wasn’t meant to be easy

[srowlandson]

Today the Gearbox mounts arrived. Yay! I stupidly had ambitions of a few hours work to get the mounts in, engine in. How wrong. After some fiddling and cursing, a decision was made to remove the seat box to fully expose the gearbox. 10x 7/16″ bolts across the back, 8 were brand new so easy to undo with the impact air gun at least and the 4 x 1/2″ bolts and the box was out. The mounts were corroded and rusted solid. Some heaving on them with the trusty JBS breaker bar and they were out. I have to unbolt the 4 (18mm - weird size?) bolts holding the plate to the gearbox to get the passenger side mount off the plate. This nut was another odd size, rusted solid and seized. Some time on the air grinder to grind the head down , hitting chiseling, air chisel, hammer, vice grind eventually anger and frustration and the hammer saw it break. I now need 4 nuts for the new mounts (which i’ll get on Saturday) with a box of 9/16″ bolts to bolt the mounts back in and replace the bolts in the tail shaft when the rear axle goes in. the good news today was the Single Hex, deep Snap on 3/8″ drive Snap-on sockets I ordered arrived Yay! Just awaiting the hinged 3/8″ drive ratchet now :)

the wierd sized bolts that were 18mm should have been 11/16ths.


old rovers are imperial not metric....

put your metric spanners away incase you round something off.

And furthermore, it is certain to have at least some Whitworth/BSF sized nuts and bolt heads - conversion started from British to Unified threads with the Series 2a and was still incomplete when Series 3 production ceased.

To work on any Series Landrover, fractional inch size spanners are absolutely essential, and, particularly if it is an early model, you need to have a reasonable range of Whitworth sizes.

I have a full range of spanners and sockets in imperial sizes, my first 2 cars were a 1970 Daimler Sovereign and a Triumph 2500TC.

Might have to get some Whitworth spanners.

The new Engine mounts have a metric thread and a 17mm nut. I have also found the odd bolt that has been replaced at some stage in the last 44 years to a metric bolt?

Any forty-four year old vehicle (especially a Landrover) is bound to have some odd bolts here and there. You can expect to find quite a lot of Whitworth/BSF, although how much is unpredictable as apart from the odd bolt entire assemblies are interchangeable with either earlier or later assemblies, and often the only (significant) difference is what type of thread was used, and after that time it is likely to have a lot of non-original bits.

I came VERY close to burning the POS today :)


Attempt 4 at putting the engine in, bought 2 x3 1/2" bolts to help 'pull' the motor onto the gearbox, all was going well, BANG gearbox mount i just installed popped, guess ihad WAY too much pressure on it, had a jack under the gearbox lifting it slightly. :(

So much for trying to do it myself and being impatience. I'll have to pull it out, drop pressure plate off and re align the clutch and try again, after i get another gearbox mount :mad:
