Motor and gearbox are in place.
Using HJ47 engine mounts and engine mount brackets the 12HT sat into place quite nicely. Especially after i spent a grand straightening my bent chassis!!!
The high pressure pipe coming off the power steering pump would of touched the engine mount so i die grinded a bit off the engine mount and a bit off the chassis engine support bracket. This was even after i found a sweet pipe at the wreckers with almost the exact bend i required. Don't know what model it came off but it was a toyota car. I had a hydrolic hose repair guy fit/weld/braze the vaccuum idle up onto the other side of the hose where in goes onto the steering box. I could of left it off but hey i've gone this far right?
Using a HJ47 radiator with modified bottom outlet to accomidate power steering pump.
I also had to die grind the radiator bracket mounting holes on the chassis and weld in a couple of washers to hold it further back as the 12HT sits at a slight angle going down towards the rear thus bottom of fan was 10mm from the radiator at the bottom. Now it's a comfortable 20mm.
I also had to cut the fan shroud in half horizontally so it can come off in two havles making changing belts easier. Matter of fact it would of been damn near impossible otherwise.
Alot of this stuffing around could of been avoided if i'd gone with an electric thermo fan (SPAL makes some very slim fans indeed) but i was hell bent on keeping the viscous toyota fan.
Top radiator hose is a shortened HJ47.
Bottom radiator hose is a shortened HJ47 cut in half with a pipe added in between so it can meet the modified bottom radiator outlet.
As for the gearbox/transfer. I'm using a 5 speed out of a HJ75 (already installed 2 years ago) mated to a HJ47 bellhousing.
Not all 2H bellhousings are the same as mentioned by dingbat earlier.
The bellhousing needs a slight touch with a die grinder in two spots to mate it to the box. It's pretty obvious.
The crossmember is the standard FJ40 unit but i used HJ47 "L" brackets as they actually line up to one of the original holes on either side!
! The FJ40 "L" brackets don't line up to any holes so you're totally guessing where to drill. The other three holes get drilled but who cares!!! You already have your centres!!!
Now as the HJ47s have a narrower chassis then the FJ40s i spaced it as follows. 10mm plate on the left and 20mm plate on the right. I simply used mild steel cut roughly to size.
Don't forget a HJ47 gearbox mount also as the rubber is thicker than the petrol one.
Might as well mention that the plate on the body that the shifters poke through will need re-fabricting as the position of the levers has moved. The front of the top loader also just touches the body. GOD i love my die grinder.
As for the tail shafts/propeller shafts.
Rear tail shaft angle is better then factory and tail shaft will need lenghtening.
Front tail shaft angle is hideous and will need cardan joint as well as shortening. I thought i could just use a HJ47 unit as it already has the cardan joint but the length is different. Maybe the diffs sit slightly different between the troopies and the shorties? Who knows.
Another issue i had was buying a 12HT clutch kit but having to use a HJ47 thrust bearing. Can remember exactly what i mixed and matched but it came together in the end.
HJ47 slave cylinder used aswell.
Can't remember any of the other stuffing around i went through to get the 12HT into my 40 but i'm sure there was heeps. Call it repressed memory. Like what train crash surviver goes through
FREE ADVICE. I was working with a rolling chassis and i believe THIS IS THE ONLY WAY way to tackle such a project and it was still a pain in the
!
Take it or leave it.
Starting the diesel beast made it all worthwhile. It came to life after not having been started for a month with just half a revolution of the starter motor. Try that with a 2F!
With no exaust anywhere in sight it reved freely and came on boost almost straight away.
The best part was standing back and watching as my mate gave it few hard revs and seeing THE WHOLE CHASSIS TWIST like liquorice under all that torque!
Anyhow after much waiting i should be getting it back from the panel shop next week (bare metal re-spray) and putting the finishing touches on it over the next month.
Will post some pics on completion.
Cheers!
