picked up a 12ht. Questions

[AGreekBoy]

going to be putting this into an87fj60. notice that the power steering pump is close to the passenger side motor mount. where does the resorvoir mount to? going to be having alot of questions. looking forward to responses thanks

[AGreekBoy]

let me know if these pics are the right size. first time loading pics. thanks Anest

Hi, nice combo, You can mount the resorvoir on the inner fender, like on the BJ 74 series.

Down on the RH side on the Aussie models

I dont see why not.

[AGreekBoy]

Most cruisers have a few spare holes on the inside of the fenders with thread in them. You just need to fab a bracket and bolt it to the sides adjacent to the pump..


For the fluid lines,they are non pressurised to the reservoir,so you could use any fuel line with a big enough diameter. I guess they woud be about 10mm inside diameter.
The upper spout in the reservoir is the return from the steering box. The bottom spout feeds the fluid to the pump. If you understand how your gas PS works ,you can just extend and plug the new hoses into the existing system.

Very NIcE!!!



As stated, bj74s have remote reservoirs for the ps pump.

Old Toyo vans (wonder wagons) share the same setup.

See if your "u pull it" has one.

Are you going to keep the vac operated xfer?


Just curious, I am NOT fishing for the part.

[mel lowe]

Could you post a pic of the other side of the engine?


I would like to see the drivers side motor mount.

[AGreekBoy]

i will be using the vacumm case. the motor now is in the corner of my garage, i will try and take a pic of it later today.

[AGreekBoy]

the motor is 24 volts and i will be converting it to 12. i already have the alt and starter. i also have the vsv shut off valve . anything else?

[AGreekBoy]

here is the pic you asked for Mel[ATTACH][ATTACH]

[AGreekBoy]

that is the 60 the drivetrain will be going in

[mel lowe]

You are building my dream rig!



Thanks for the pics.

Nice engine.

You will need a 24v. oil pressure sender.

You will need 12v. glow components. If you want to keep the stock Superglow set up with glow screen, you will need the main glow relay, and sub glow relay in 12v. versions, along with 12v. versions of the current resistor and current sensor (these you will find screwed into your intake manifold above the starter). You will need a 12v. glow timer. You will need the 12v glow screen.

The cost of oem new parts for all those areas will definitely be a chunk of change. You may find availability of the relays, glow screen, and timer not so good, depending upon the year and model details. Good luck if that is the direction you head. i had a lot of frustrations trying to locate the correct glow relay for my truck - a lot of that 'early' stuff is not made or stcked by Toyota any longer. The only engine electrical relay i could find was a starter relay, and that was a model 3 years off from my truck.

I looked for these parts directly in through a contact in Japan, and in Australia, and Canada, and had no luck. YMMV.

I also obtained a 24v. engine, a 2H, and converted it to 12v.. I removed all the Superglow stuff, and went to an older type of glow system set up, which is a bit simpler. With a glow screen set up though, and the turbo, you don't have much choice and need to keep the glow screen. to go to glow plugs instead would necessitate a cylinder head change, and i imagine you don't want to go in that direction.

FYI, I have a brand new 12v. Toyota oem main glow relay. Will sell for $200. PM me if it is of interest.

[AGreekBoy]

thanks for all your info very helpful. i will let you know about the glow screen. let me set it in the truck first. waiting on some parts to come in should be here either this week or next.

[GM60]

I don't know how cold it gets in your neck of the woods, but I wouldn't worry too much about the glow screen at this stage.

The indirect injection 2H is an engine which needs to be glowed to start when it is cold, that's for sure.

The 12HT is a different deal altogether, being direct injected, in most conditions it will fire up straight away with just a touch on the starter, and idle fine.
12HT's start real easy even down around zero deg C.
I've seen a 12HT with 500,000k on it, fire up with just a half second hit on the starter even with heavy frost all over the roof and bonnet and temp under zero C.
When temps get way below zero, it may be a different story, I don't know as I've have never been in that situation.


They really are a nice engine in many ways.

[jb BJ73]

hey fellas
nice score on the 12H-T! i just got one myself weekend before last to go into my BJ73, goona be a while before it happens but. as you motor is still on the floor, just wondering if i could ask a big favor and take some pics of where the power steering pump is mounted to the engine? the motor i've got didn't come with it, i've got the pump and brackets and stuff off another 12ht so it should bolt up, but some pics would be much appreciated.

[AGreekBoy]

i am at work now but this afternoon ill try and get some better pix for you.

GM60 i here the same thing about the 12ht thanks.

[AGreekBoy]

hope these pics will help you

It should go very well in a 73
Did you get the gearbox as well?

[jb BJ73]

just had a quick look and it seems like it should work, thanks for the pics should mount up to the holes i've circled shouldn't it?
it's not gonna be left standard either rosco ,so it should so it should skoot along nicely. didn't get the gearbox unfortunately, its out of an auto so i'll need to get a flywheel as well. you wouldn't know if an auto starter will work with a manual flywheel would you?
sorry about the hijack greekboy

My guess is the starters will be the same as I think the driveplate on the auto is the same diameter as the flywheel.
But check 1st.A good 4wd wrecker like Midland 4x4 would be abe to tell you for sure.
You can use a 2H starter also and they are fairly common
I thought I saw a heap of 12HT stuff in the Quokka inc a PS pump for $50 in mirrabooka

[AGreekBoy]

hey Rosco, any idea on how to make the 24volt diesel tach work with the coil 12volt tach from the gas engine?

Nice pics .. yes those are the holes .. BTW the worse place to run a PS pump .. aaahhh Toyota .. love it or hate it.

LOL Thats a curly one. It might be easier to convert it to how Toyota did it on a 60 series with the pickup in the bell housing.
You then join the wires from the bell housing to the wires from the alternator to the dash but you would need a 12v tacho.
If you have a 84-90 body chassis manual you will have a better idea.
The 60 and 70 series of those years share an identical wiring lay out
Otherwise ,my auto electrician says there is a place in Balcatta that can modify a tacho to suit any signal and you could use all sorts of signal pick ups

[AGreekBoy]

my wiring harness is 12volt. do i need a different tach, that read like the hall effect.?
