interchangeability

[bad_religion_au]

ok, since the transmission is the last straw, i need a parts rig.

40's and 45's are fairly expensive as parts rigs, 60's are too,

what i want to know, how do the transmissions from a

post 79 fj40
hj45 or hj47
bj40
fj55 (and difference between years)
fj60
hj60

compare with a 1976 fj40. what is the same, what is similar enough to bolt up, and which could i use most of. for instance, which 55's had disk brake axles, i know i can do a disk swap using 60 series stuff (on my 45). 60 series gives me power steering too. 55 series gives me some back springs for the 40.

what i am asking for is an opinion. the 55's seem to be cheaper than the others, for more of a rig (road worthy for 2.5 grand, as aposed to a non running 45 for the same price).

panels aren't a huge concern at the moment, but a couple of 40/45 panels would be handy.

oh, and what year did 40's go to the 4 speed?

oh, and does the hj45 and fj40 use the same clutch?

Didnt know you could get so many questions in one post

Have a look at these but remember its slanted towards north american models:roll:

4 speed went to 1984 in the HJ47, 1981 in the BJ/FJ 40-42's.

Post 79 or 81 (can't quite remember) is the split transfer that is the transfer of choice.

Post '79 also for disk brakes.

You can buy a early 60 for under 2k with rego and you get wider housings as well as power steer and discs and split transfer but depends on the year re 4 or 5 speed.

[bad_religion_au]

would a 5 speed from a fj60 bolt up to my 2f? or would it take a lot of work?

[roscoFJ73]

The gearbox will fit but the t/case off the 60 series is too wide for the 40/45 chassis according to the guy that tried it on the IH8MUD forum.

[bad_religion_au]

so will my transfer case fit the 5 speed? not a good idea, cause i'm still not convinced my transfer case isn't the root of all evil. does the transfer case on the rear of a 4 speed fj60 fit a 40 chassis?

[ORSM45]

nah its the same transfercase. all you will need is longer tail shafts on the front and shorter on the rear. all 'f' series engines bolt to 'f' series box's. some box's have longer input shafts, i think it was the diesels.

also the selector rail on a 60 series 5 spd is different to a 40 series 5 spd. so if you buy the 60 series box you will need to modify the hole where the gear stick comes through.

i have a 40 series 5 spd for sale at the moment.

yeah, and i believe we both know the previous owner of that car. i was hoping to get a donor vehicle for the price of that 5 speed, as that price is about my budget for getting the 40 going again, and i need a few other bits for it as well.

ah well.

he is gay or full of it, they fit with miles to spare on my rig. I have done two and seen 4 others, the 4 and 5 speed form the 60 series is the same as the 4 and 5 speed fitted from the factory after 1980 to all 40 series anyways. So yeah, its no worries getting it to fit.


You could get a petrol 60 for $1500 or less with a rusty body, then all you need is to bolt all the stuff onto your rig. Or sell it and buy mine.

[bad_religion_au]

yeah i thought you were running a 60 series case in your 40 Bj. now i gotta find a 60 series.

thanks guys.

how much longer is the 5speed/transfer case combo than the 4 speed?

and how much approx. should i be paying to extend or shorten driveshafts, i got no welding ability

[ORSM45]

i also have a 60 series box in my 45. pretty sure its 3 inches longer.

and bj they arent identically the same. the selector rails are different. on the 60 series, the gearstick is mounted at the back of the top plate and on the 40 its up the front. this minor detail was important to me when fitting my V8. coz i didnt want my gearstick in my heater.

but if you put a 60 series box behind the 2F it will mean your gearstick will be moved a bit too far back.
