Rebuild 74 FJ40 RHD from Down Under - 2F to 2H to 12HT - 40 series Axles with 80 series Coils

[watrob]

Started the rear disc brake install, I am using Toyota disc brakes as they use less space due to my 80 series suspension.

Attached the caliper for test fitting, all good so proceeded to fit hub & rotor with new bearings & seals.

Also installed coils & shocks at the same time.

Caliper has 5mm clearance from panhard bracket, close

Here are a few more photos, all that is left is to install the rear Lokka diff & axles.

This morning I started on the front axle assembly, installed the new bearing and seals into the hubs, installed the front springs (shocks won't arrive until Monday afternoon).

 

[watrob]

The installed top & lower bearings and inserted the SST for the right hand knuckle.

Inscribed the first line on the SST.

My front FOX shocks arrived this afternoon.

Looks great mate your getting lots done now

Finally chased down a throttle damper for the 12HT, off a very early (around 1993) Mazda 323. Just need to fab a bracket up to fit.

Thats interesting. Where abouts do you attach it? Looks like it's vacuum operated?
My throttle could do with a little dampening.

My throttle could do with a little dampening.

Its passive, no vacuum needed, where the throttle has a small bolt that adjusts the idle you replace it with this damper, it slowly lets the throttle return to idle. Its has a thread & lock nut adjustment so to set the idle speed.

I will have to make a new bracket so it fits.

Gotcha,
The problem I have though is the trottle is very touchey and tends to lurch if I go on the gas too quickly. So I dont think this will solve my issue........or would it?

You need to replace the two springs on the throttle?

Here are the readings for the knuckle rebuild, SST with bearing installed. This measurement "A"

And right hand Knuckle size, this measurement "B" the difference gives me the total adjustment shim "C" = 2.14mm, to start the balance of calculating the top shim size. ( C = A - B )

Hi
Neat tool. This is the first time I have seen it in use.
Will follow the next threads you post with great interest to see the results.
Keep the photos coming.
Cheers

Picked up my 316 stainless steel 3" tubing for my exhaust this afternoon. 1 x 3 metre length of 3" tubing, 3 x 45deg bends, 2 x 90deg bends, total cost $245.00

 

[watrob]

Now placed the SST tool into the knuckle and scribed the next mark.

The distance between these two lines "D" is 3.45mm. To get the lower shim thickness "E" is D - 3mm = "E" which is 0.45mm.

To calculate the top shim "F" is to take "C" 2.14mm - "E" 0 .45mm = "F" 1.69mm.

So top shim "F" is 1.69mm

Bottom shim "E" is 0.45mm

You then do the same procedure for the left hand knuckle.

 

[watrob]

Installed front E-Locker diff.

Installed new front right hand side front axle for test fitting.

 

[watrob]

Can you pick the problem with the front left hand front axle? (it's lined up against the rear left hand axle for comparison)

 

[cruisermatt]

Yeah why is it so much longer?

Hey Rob, I read and re read your thread, an amazing inspiration to us all..

I have a question, In your first post you say, "1983 rear full floating hub with diff so I can install Hilux disc brakes with solid rotors". Do I read this right? In your rear disc conversion, are you using the Hilux front disc rotor (solid) calipers and caliper brackets from a '84 Hilux?? The question relates mainly to the caliper brackets..
I have '82 BJ40 axles and brakes under my old '73 40.

If so, theres a '94 down at our local Pic a part. I will shoot down and grab the bits..

Thanks in advance..
