HJ60 frame and powertrain swap (12ht A440)

[Tapage]

50psi is the top out I believe

race engines !

Or a power stroke or cummins can handle 50 PSI . ?

I have been trying to track down a vibration in my drivetrain and think I finally found the culprit. It looks like there was a balancing weight welded onto my driveshaft that has come off. I pulled the shaft today to get it rebalanced.

The newly balanced driveshaft makes her drive like a dream! Now just to finish up the electronic loose ends and all is well.

Any chance on a video clip?

Happy to post one when I am back in the country in Feb.... What type of video clip are you after?

 

[hks3sgte]

I would just love to listen to the engine idle! Maybe even a drive-by type of video??? Thanks!

The engine sounds nearly identical to the 2H until the turbo kicks in which almost sounds like a very far off siren as it spools up. I will try and get a moving recording...

As requested here are a couple videos. You will likely need headphones to hear the turbo whine.

This one is of the engine starting you can hear the turbo right after I rev the engine up a bit:

This is one from inside the cab. You can hear the turbo whine in the background sort of like a remote siren:

Thanks!!!!!! Sounds deeper than a 2H? Or is it just me?

 

[zander]

Hard to say, but my memory is its about the same except the turbo whine...

 

[hks3sgte]

Could be the 3" exhaust too, no?

True, you have to use the gasser cross member and tranny mount.

Welded in a set of HJ61 motor mounts, dropped the motor inot a late model fj60 1982 and she all bolted up nicely.

Try this one of these days - turn your snorkle intake backward, roll down passenger window and get the combination of exhaust and turbo whine with ever so slightly offset timing.

So I am still very much in need on this Vaccuum diphragm valve... Anyone havea line on one? Parted out blown up 12ht anywhere in the world?

Here are a couple pics, also note that 2H one looks almost identical but wont work as it has a different bracket and a different stroke length (if you click the pics you will get a blow up):







I have not found a part number yet.

I'll be in Europe later in November. if you still need this part, let me know. I can grab one for you.

 

[zander]

Sheldon finally found one of the vaccuum valves for me!

Gauges and heat mitigation installed...

Vaccuum switch has been in and working for a while. Nice to have the auto idle up.

I also finally got around to installing my gauge pods for a month long trip in eastern NV and the eastern Sierras. I put in 24v gauges for trans oil temp, turbo boost, and a pyrometer. Install pic:

I also did some other mods to allow the truck to handle heat better...

A SPAL 24v 12inch pusher fan (which of course required moving the trans cooler and modding the central upright and grill):

Hood louvers to let heat out:

Made a diverter for the windshield fluid to spray water on the radiator as a last resort for super steep sections:

I have been using the set up for several days out here in the desert and its been doing great. Two questions though:

1. Now that I have the pyrometer I am concerned about my EGTs. Its pretty hard to keep out of the red which starts at 1050F or so. What is a safe range for a 12HT?

2: I have yet to figure out where to install the thermal sensors for the trans oil and engine coolant (to turn the fan on automatically). Anyone have suggestions for a 12ht?

Is your pyrometer pre- or post-turbo? I think pre-turbo pyro EGTs should not go over 1200 but I could be wrong on that.
