'82 fj45 gearbox conversion

Unread post by Wednesdayfades » May 12th, 2015, 9:17 am

I'm looking at converting from 4 gears to 5.
learning as I go, but from what I understand I can take the gearbox from a 60 series and it will fit into the housing of the 45.
I have only really been able to find information for diesel trucks, is there a lot of difference in the way of petrol?
my truck has the 2f engine. Basically wanting to know what type of trucks I can take parts from and any issues I may encounter or other parts worth taking from wrecks.

Cheers.

Hi mate, I have done this a couple of times.

1st. '82 is a change over year, is yours an early '82 of later '82. (does it have front disk brakes - and/or a taco on the dash)

Here is a rough list of parts,
3F (FJ60) Gearbox and transfercase (must be early FJ60 without vacuum transfercase)
XJ60 (doesnt matter) rear brake backing plates, and brake particulars for the handbrake.
VDJ79 handbrake cable.
Longer drivershafts (get these made specially)

Now the gearbox cross member mount is tricky - I have no idea if the FJ45 has the same as the HJ47. If you take a photo of what you have currently I will tell you what you need.

If you want your taco to work, well thats another question.
'98-'06 - FJ-45 Ute fell over one day and didnt survive
'06-now - HJ-47 Troopy, restored and now daily driver.
'13-now - HJ-47 Ute, Farm fresh rust bucket, needs a restoration. viewtopic.php?f=22&t=152811

now - Off Road Box/Camper Trailer. viewtopic.php?f=134&t=153968&p=1792444#p1792444

Dont listen to me, Ive got an opinion on everything!

I think they did 2Fs with a 5 speed (in the post 82 60 series, up to about 84 when the 3F came in on the FJ62 - which had the vacuum transfer).

Just get a 5 speed FJ60 and part that. It will have all the kit you need I'd say.

As for the tacho, just hook that up to the coil (the negative side I think). Look at a wiring diagram. Petrol tachos are easy, or get an aftermarket one for $50 and hook it up like they do on the old kingswoods (eg tap a wire onto the -ve side of the coil).

I read this as Wednesdayfades only want's to change the Gbox from 4 to 5 speed, how will that effect the tacho am I missing something?

2H takes a tacho reading off the bellhousing, so if you changed that, you might loose that sender.

if its an early '82 it doesnt have a taco, if its a late one then it comes of the bellhousing, if you end up needing the 60 series bellhousing to mate the GB to the engine then you may end up with incompatable taco senders.

Ok so is that the case with the 2F as well? It would have been a lot easier to take a signal from the coil.

Thats why I was unsure, I havnt ever owned a petrol 40 with a taco, but in the end this may not matter at all - as he may not have a taco.
