Recently an early Patrol slid backwards and rolled on a really badly rutted steep track late one week night.
The kids took the call dragging themselves out of bed and arrived on the scene around midnight.
A high level of capability was required and they took a 4800 GU Patrol which had just been fitted with 37 inch Maxxis and a prototype dual plate clutch.
The rescue was really hardcore and went on for hours involving 3 cars belaying the stricken vehicle down the slope inch by inch.
The 4800 GU took the main load constantly re-positioning itself and it was to much for the on/off prototype clutch which shredded its ceramic linings on the last section of the recovery.
The rolled car was however recovered and the 4800 was jammed into 3rd and limped back
home about 4am.
So what to do ? - I'm not a mechanic and the manual box in a GU is a really heavy truck grade monster and relacing a clutch in it can't be done with
home tools.
This is where I learnt something from the kids , I didn't have time to tell them it couldn't be done and before I knew it they borrowed an engine crane and some mates and shoved it thru the drivers doors and lowered the gearbox
to the ground - thanks to the huge tyres there was reasonable working area under the car and a couple of days later it was all over and cost nothing.
They did however leave plenty of oil stains in the driveway just to make sure the parents got involved.

Didn't think this could work on a GU

G'day Robin.
Sorry, BUT,
Lots of people do repairs at
home and a crane is often featured, no surprises there at all.
The only thing there is, I wondered why the parents didn't know how to, either do it, or know of the possibilities.
Perhaps no mechanical aptitude or abilities and low awareness of the features of the vehicle.
The reason the crane goes in the RHS is because it is thinner than a human and the human attending can get into the zone through the LHS. The steering wheel would prevent the human from easily accessing the top of the work area.
This way it will work.

I'd call that assessment a little unfair.
Anyone who has removed a Patrol gearbox, including many mechanics I know, strongly advise against doing it this way. In fact for some models, I'm informed the gearbox has to be rotated through 90 degrees in order to come out. I've never weighed one but I am told it and TC weigh 220kg, that is a big ask!
The use of a crane for mechanical repairs may be nothing new, but replacing a Patrol gearbox at
home in this manner is a big ask. Just shows that if you don;t know how difficult it is, you will probably give it a go- the rest of us take the engine out instead.

correction "replacing a Patrol gearbox in this manner" should have read "replacing a Patrol clutch in this manner"

Yes Olsen , that huge box can't be taken directly out even with a proper transmission jack , it has to be manovered past the starter housing in two stages.
Hi
Ross
The parent (me) isn't completely without mechanical ability but I am
to logical an engineer not to access the risks up front and decide to let someone with the right equipment do it - but the kids have no money and to some extent work within these constraints and come up with some surprizing innovations espically when you consider this is their first.
They even used a heavy duty bike tie-down instead of a chain to hold the box to enable extra adjustments that need to be made independant of the engine crane.

Now thats a good idea
