Will you be able to sell the old box to offset some of the cost?
That’s interesting as when I’ve been on the factory tours they make a point about talking galvanic corrosion and how they try to prevent it. Using alloy bolts seems the easiest first step.Steel bolts into an alloy casing is fairly normal unfortunately. From what a dealer was telling me recently JLR specialise in it on the aluminium cars.
Good call and one I was about to say.I have steel bolts into aluminium on my m/c. After drilling seized ones out I use aluminium anti-seize compound, which so far has prevented seizing again.
Just use a thread-lock. Separates the metal but keeps the bolt/set-pin tight.Thankfully on the Range Rover gearbox they're M6 bolts that are just used to hold the wiring looms to the gearbox so they just need nipping and not much more.
That's always a worry I have using compounds on other bolts though, especially crucial ones that need specific torque values.
I can so appreciate/understand that!!..The little tracked machine is a Ransomes Crawler MG2. There's a few of them in the other workshop. They made an MG2, MG5, MG6 and an MG40. We've got a 2, 5 and 6.
They were made in the 50's and designed to do 2 horse work at 1 horse speed. That one in the picture is disassembled and having the engine rebuilt at the moment. That's my Dad's project rather then mine though I just enjoy playing with them and finding jobs that they're totally inappropriate for when they're working
All of the tiny little bolts on my gearbox came undone last night so I don't know why these ones have sheered. Seems strange given the box is much newer then the one in mine too!
