how to tell if i have stock axles

[Cruiser68]

I guess i have to open it for you guys later on. Do you know if there were a change in brake wheel cylinders between 68 and 76 or will the rubberparts fit either axle?

In the US, yes..Single or dual reservoir master cylinder?

Probably need to post pics of those as well.

I have a single master cylinder

Yes i will do that

Sometime around EDIT: European spec '76 or '77 the FJ45 got the wider drums front and rear - caught me out when I ordered some. No disc's that I know of.

Note this is just from the small number FJ40 & FJ45's I know of in Europe


Take a picture of the drum with the wheel removed, the wider drums have a sort of shaped profile, ie the face the wheel bolts onto is not flat.

ok here is the pic . I guess this is what you mean with shaped profile, right?
I also found out that the wheel cylinders on the front axle are 1 1/8" according to the seal. On my rear wheels both pistons in the wheel cylinder are preassured by rubber seals but in front there are only one seal in each wheel cylinder, i made two photos of some of the parts with the ones for rear axle are in the first pic.

subscribe.... I am interested in the answer

There were no SWB 40's with 1 1/8" cylinders in the front. My truck came from New Zealand with a junkyard front axle that have 1 1/8" cylinders in it, so I spent a long time pouring over the EPC trying to figure out what I had.

The only 40-series application for the 1 1/8" cylinders was for 45's... so you have a 45 front axle.

(This is all from memory, but seems simple enough...)

EDIT: Here is a page from the EPC showing the "28.5mm" (1 1/8") cylinders for 1976 BJ45, HJ47s, and FJ45s: http://www.toyodiy.com/parts/p_G_1976_TOYOTA_LAND+CRUISER_FJ45RP-K_4704.html

this is the correct kit for my front axle:

Kit, wheel cylinder, front 31.75mm - Offroad Shop

31.75mm?????

31.75mm = 1 1/4"

I still want to see what's inside that rear housing..

[avgas]

nobody knows WTF this thing is, my curiousity is sparked and the thread is drifting into oblivion.

bump

 

[amaurer]

Seriously, open that thing up!

A custom locker would be awesome to see, but given that the linkage has a certain "booty" flavor to it, I'm not hopeful. I'm thinking more like a ghetto ebrake that just crams a lever into the carrier....

 

[avgas]

I doubt it's an e-brake, I think it's some sort of old school selectable locker, to me it's not so much booty-fab just old school.

 

[joeyg1973]

I am thinking it is something that acts like the TO bearing and fork that forces a gear in to drive both at the same time.

 

[Cruiser68]

31.75mm = 1 1/4"

it says 1 1/8 on the seall

Seriously, open that thing up!
.

Ill promise to give it try this weekend if i get the time
keep this thread alive so i dont forget it
What type of oil and how much do i need to buy to replace the old when i open it up?

This is a bit of arm-chair engineering, but its fun to guess whats inside there:

The 80-series lockers use an arrangement like what you describe: the fork slides a collar with some gear-like teeth on it along the axle shaft, which engages teeth on the side of the carrier and locks the axle shaft with respect to the carrier. The spider gears then also lock the other side in place.

I think thats unlikely in this case, for a couple of reasons. a) the taper on the axle shafts for semi float make it impossible (or extremely difficult) to create a long splined area for such collar to slide on. b) even if you got a collar on there, there wouldn't be "teeth" on the carrier for it to mate to.

Its not impossible that someone added all those features... but that'd be... interesting.

All engineering starts in the arm-chair.

 

[numby]

Appears to have two mechanical stops to limit range of operation. One seems adjustable.

I'll guess... parking brake.

Probably a sliding collar locker gizmo as mentioned above.

 

[mminter1973]

That thing must have 10 shift levers in the floor to operate all that stuff
