Hi there all
Well the BJ73 is now all registered fitted with 6 cylinder 2H. Initally I thought rego was going to be an issue but very easy - do it right and there is no probems.
But for all those out there you do need to move the engine mounts.
I have a couple of questions for the forum's exerperties - tried to ask our local TOYOTA dealers but without being blunt I will never take any of our vehicles there again (hopeless and didnt really care - poor customer relations?).
1. I used a 60 series wagon as a donor engine and gear box, the biggest problem i currently have is engaging 4x4. The 60 series gear box is an electric push button to engage 4x4 can these be converted back to the standard mechanical lever (as in my old BJ73). I am assuming not but if some one had done one please let me know.
2. The gearbox also has an overdrive fitted - how do these work and how do you engage them. It has aditional lever (shifter) within the cab but before I have a play and break something is there any instructions or thing to be careful of prior.
As for the power difference between the 3b and 2h - so far there is lots of torque and power.
I am looking forwards to feedback
Wayne

2H Diesel into a bj73 MWB Questions
Moderators: toaddog, Elmo, DUDELUX
You probably could change the lever but it might be easier to get the switch and other bits for the electronic 4x4 engagement. My BJ74 has the electronic, so I am assuming it's just a matter of adding the harness and switch.
I take it the gearbox you transplanted is a 4 speed with an overdrive. If not, it might be a PTO engagement?? Can't relly help you with this one.

Re: 2H Diesel into a bj73 MWB Questions
I have converted a vacuum-activated transfer to mechanical shift in my HJ75. There is also another brief discussion about this recently. The easiest would be to switch the entire front half of the transfer case to a manual shifted one (be sure to use one from a post 10/85 donor to ensure the correct idler shaft size.) You'll need the entire front half.ellard wrote: 1. I used a 60 series wagon as a donor engine and gear box, the biggest problem i currently have is engaging 4x4.

Another way is to remove the vacuum diaphragm assembly and switch the front drive controller shaft to a manual unit (part no. 36313-60050) and to fit a detent ball and spring to the case. You should see where there is round depression on the side where you are to drill. Threading the hole is a bit difficult as the specific tap needed (15mm x 1.25) to fit the genuine Toyota detent cap is difficult to find as 80UTE stated. The manual rubber boot will fit perfectly on the hole left on the case after the vacuum unit is removed. You also need to use a high-low shift lever from a manual transfer (part no.36307-60030) to change the lever's action from side to side instead of fore and aft. Of course you need the shift lever assembly from a manual transfer.
Do you have an overdrive box or overdrive gears? Overdrive gears are engaged by default whenever you are in high range and requires no additional engagement.ellard wrote: 2.

There a couple of overdrive boxes that have been fitted to the landcruiser transfer case. One of the early ones is the Fairey overdrive:
It is activated by a lever connecting to the pin just below and to the left of the removable cover seen in the picture. The overdrive is distinguished by the thicker rear half as compared to a stock factory case:
There is of course Marks4WD's Cruiser Crawler Transmission, but as far as I know at the time of this writing the model to fit the 60/70 series is not yet available to the general public.

hi there
Hi there Dave
Many thanks for the help - I decided to re-fit the Vacume shifter (with dash mounted push button). I understand what you were saying this was my views also you have to change the transfer case. Its still an option as I am not a big fan of electronics just another no-necessary item to break or fail.
As for the overdrive (your first picture) with a selector lever. From what I have been told these only work when you are in 5 gear and it justs reduces engine rpm there-fore lowering fuel consumption. I havent had a play yet but will go for a drive in the am on the highway (not really fussed with this just on the vehicle when purchased).
I will have to take all the transmission tunel cover out again in the morning as while playing with the manual selector shifters I must have adjusted the length of the high-low arm and its now jumping (not quiet going in properly) out of high range - shouldnt be a big problem.
Many thanks

Re: hi there
the fairey manual states that you can use it in high range, 3/4/5 gears, as a splitter and overdrive. If you love it, keep it, but spares are rarer than rocking horse poo and very expensive if you can find them. Possibly the best thing you can do is pull it off, box it up and sell it to a collector, it's fairly valuable as a unit. The big broblem with those overdrives is the nut on the end of the main shaft (tranfer input shaft) comes undone, and the synchro units drop the shift plates into the bowels of the gearbox.ellard wrote:...As for the overdrive (your first picture) with a selector lever.

the downside is, if you pull it off, you'll have to find half a transfer case to replace the outer case, although the fairey case can be retained without the gears inside as a regular transfer.

Over drive unit.
Hi there
Many thanks for your response.
I have never used an overdrive unit before but I a familliar with PTO's (Collector of Land Rover Fire Engines PTO pumps,winches etc) but working within the mining industry we get used to toyotas and spares.
Do you know of anyone whom may be intersted in the overdrive unit and what are they worth, in saying this I am keen for these sorts of items to go to collector-restorers.
Hear from you soon

Re: Over drive unit.
Just to give you some idea, I tried to sell the Fairey OD unit pictured above for a mate in the US for over $500 for a few months before we gave up and as far as I know he still has it, LOL.ellard wrote:

Replacing the entire transfer for a manual shift transfer would probably the go.
