Hi all,

Just got back from the Beach house after dropping the FJ40 off to get the tub pre-fitted onto the chassis beacuse of the extension.

Yes I did get the tube from OZ East in Noosaville, does a petty good job. I got them to extend it by 7" in the end as I wanted room left in the rear as I am also fitting rear seats.

The sports tub will be a cross between a SWB and a FJ45 rear end.

Yeh $3,500 is the base cost, by the time you add the tail gate, wider rear wheel arches, windscreen frame, a 7" extended back in comes to around another $1,500.

While I was there he showed me an original bezel from an early 1960's FJ model with the words Land Crusier stamped in it, got him to make me a fibreglass one.

Oz East has nice small operation going, builds 2 tubes at once plus pumps out, bonnets, front guards, grills, flares extra. He said he's flate out with a 4-5 month waiting list for tubs.

Anyway, I pick up the tub from the paint shop on the 21st Dec as well as the bonnet, guards, grill, bezel and windscreen which are being painted at the same time.

So I will have plenty to do over the Christmas break.
 
hey mate sweet build up looks like its coming along pretty well, just wondering what brand of glass tub your going with and how they're priced, i know theres a place up the sunny coast called oz-east fibreglass but they want at least 3500 for a tub :eek:
also where'd you source the brackets for the rear discs????
cheers

Hi Dan,

The rear disc brackets are originally made by Eureka 4x4 in Victoria and are setup for using the 1984 Hi-Lux front disc calipher which takes a solid rotor.

The calipher is identical to the front disc brakes on the fJ40 (4 pots, 2 large, 2 small) except it will only accept a solid rotor. Also it only fits the FF rear axle.

You have to source the caliphers & rotors yourself and you also have to machine the rear hub smooth to accept the rotor. Also longer wheel studs are used because of the thickness of the rotor.

You can only put a solid rotor on the rear if you want to register the FJ40 in Queensland, not sure about the other States in Australia.
 
Did you use the welding method I prescribed or a different method?
Long-term cracking was also a concern for me. The fact that the pump bolts into the pump assembly was the big reason I wanted to relieve as much mechanical stress as I could.

Hi Eric,

Yeh, I used the same method as you did, I preheated the bracket to get the chill of it and welded it using a rod with a high nickel content.

There is not to much stress on that side of the PS pump and on the front bracket 2 bolts actually hold it in place. Spoke a mech who had done a couple of these 2H installs and he reakons to does not worry about supporting the back of the PS pump at all on the rear.

But he did tell something very interesting, he said that Toyota did produce a engine bracket so you could install PS on the 2H diesels that came out in the HJ45 & HJ47 and that they are very rare.

He said he installed a 12HT into HJ47 and the owener supplied a bracket that was a cross between like the ones we welded and the original 60 & 75 series brackets that are on the 2h & 12HT. The only difference was it came with a wedge block that sat on the egine mount to take up the different angle that the 45 & 47 engine mounts have, which as you known are different to the 60 & 70 series. Now that would have saved alot of trouble.

It would be quite funny if you walked into a Toyota dealer and he looked up the old parts list and said yeh we can get them, 6 weeks ex Japan.

I think I might do a little home work and see if I can find one, it might have been a dealer option maybe or an factory option near the end of the HJ45 & HJ47 life span because all the 45 & 47 with 2H I have seen have never had PS.

Why do you say that ?

I have vented rear disc kits on the shelf for other cars, don't have them for a 40, but have never been asked. Why do you say they have to be solid to be approved in QLD ?

Hi,

It's something to with the age of the vehicle (my FJ40 is a 1974 model). Even though I have put a 1984 FJ40 FF rear axle which had drum brakes on it, no vehicle of that era had vented disc's on the rear.

Vented disc's were appoved for the front only and solid rotors were ADR approved on vehicles first, then solid rotors were approved for the rear, followed by vented on the rear of vehicles in the very late 1990's.

I was told that putting vented on the rear would not get approvel due to the weight of the vehicle and of its year. Also the fact that it was a live axle. FF and that I could not show that any other LC or Hilux with a simular axle setup had a vented disc whereas there is with solid rotors.

It's the same for the tyres & wheels, in 1974 there was no tyre sticker for the FJ40, so they revert back to only allowing a 30% increase from what was on the vehicle as standard and that was 16" rims and it relates to the overall size on the tyre as well.

So I installed on the rear of my FJ40 caliphers from the front of a 1984 Hilux which had solid rotors which later appeared on vehicles on the rear. The person doing the Blue Mod Plate roadworthy, as soon as I told him I was doing disc brake rear the first thing he asked was it a solid rotor.


Also I have been told that if you want to register a vehicle with a motor change as from March 2008 in Queensland you will only be allowed to put a simular motor into a vehicle as the one you took out. That is a 6 cylinder petrol with the same capacity as the 6 cylinder petrol as you put in, 4 for 4 and V8 for a V8.

mmmm ok I would suggest that whoever told you that is wrong. Under the codes your vehicle should now have being LG1 (Design) and LG2 (Modification) there is no requirement for solid rear rotors.

In the relevant ADR 31 is makes no mention of it, depending on the ADR's your Cruiser has to comply which is on its plate, it maybe pre ADR 31, there is no issue with upgrading to comply with ADR 31. being a 74 it should be ADR 31 compliant.

I would be interested in finding out which engineer told you about the vented brakes being non-compliant and also what AO and Design number your rear disc conversion complies to ?

Out of interest I confirmed this with QLD Tpt today whilst I was discussing an ICV I am building which needs to be 2007 ADR compliant and funnily enough has vented rear rotors.

Cheers,

Hi,

I understand what you mean, but I did not want to press the point. I think when my plate was checked and the type of axle I am converting, problem was getting a Blue Plate Moder to sign off on it.

It's bad enough with the fibreglass tub and getting the machinery permit from the Qld Inspection Station as the Blue Plate Moders cannot do it. So the FJ40 has to go for inspection and all mods that have been blue plated still have to be listed on the Modified Application Form and they have indicated that each one will be checked by them.

Anyway a solid rotor suits me (less rust) as the FJ will be full time at the Beach House and their is no road, only access is via the beach.

I probably would have been better off leaving drum brakes on it, it's just I thought the discs would be easier to work on. Solid rotors on the front would probably last longer as well.

PS. I located the plate as I had given it to Oz East who making the fibreglass tub so they could attached it. There is no ADR 31 on the plate.

There is ADR 7 which covers hydraulic brake hoses but I believe that was repealed in around 2006.
 
hay very nice shorty build just starting a 74shorty myself over here in the west thanks for the info would like to see more
 
Well I have finally finished the the FJ40. It took 2 weeks to get it registered.

Had a minor wiring problem but managed to strace the fault. Hoprfully I will be able to put the 16" alloy wheels on next week with the new tyres.

Anyway here is the finished product, it is all fibreglass and the tub was extended 6 and a half inches at the rear.

The 2H Diesel performs well, at 2000 revs I doing 80kph and at 2500 revs I am doing just a touch over 100kph. I can idle in second gear through fairly heavy beach sand will no strain on the motor.
