1HDFTE - FJ62 conversion (Australia 60 Series )

[cruisermatt]

I love it. Can't wait to put a turbo 1HZ or 1HDT in an FJ62 one day.

It's also cool to see that it can be done in only a little over a month.

I have a stalling problem when after trailing throttle down to a low engine speed, if I dip the clutch the engine will stall. It's starts right back up again

This sounds like a classic speed sensor issue. My 79 ute behaved in the exact same way when my speedo wire tore out at the transfer case. It would stall out when coming up to a corner and depressing the clutch. It would also start back up straight away. The ecu needs a speed signal to keep it from stalling. The down side is it also tends to make it hold its revs between gear changes

Thanks for that info Locked, I'll report back when I get to the bottom of it.

Update: I'm not certain what's happening but I've found that disconnecting the diaphragm for the intake shutter has stopped the stalling. I haven't found any supporting information (70 series based) but it appears the intake shutter is at least partially closed on back throttle and the EGR opened. As I have the EGR disconnected the engine can't get any intake air and stalls. The later 100 series used a stepper motor to control the intake flap for this function and I assume the 70 series is doing something similar via it's VSV.

Having it disconnected does make the engine shake more during shutdown and that was the original reason for Toyota fitting it. It's no worse than any regular diesel engine and if I didn't have the benefit of experiencing it I wouldn't know any different, so I'll let my wife be the judge.

That would be great Dan, hopefully it gets the job done.

Report:

Success! I bought a Parker Tool hand beading kit (No. 416). Old (1950s probably) aircraft tool, in a Bakelite case even!

And here's a bead I just made. This is aluminum tubing (if it's good enough for airplanes then I will secure it similarly on the cruiser and call it good):

Very pleased, because now I can fabricate my lines and make them exactly how I want!

I'll bet a local airport, maybe with a mechanic who works on older airplanes or restoration of tube and fabric planes will have a tool like this and could bead your tube for you.

Kind of a pricey tool, but I shall want for beaded ends no more!!

The intake shutter will also stop a runaway diesel if you turn the key off as it closes off the airflow. Its not really an issue on a good running diesel though.

Hey @dousty , do you have a mate with a 79 1hd-fte. If you do, pull the windscreen wiper fuse and go for a drive, it will mimic the symptoms that you are having. The windscreen wiper fuse also kills the speedo.

 

[dousty]

Yep you're right and I'm not concerned about it running away.

I followed up on your vehicle speed suggestion. It has a lot of merit and would make sense. A couple of things I'm still unclear on is why I'm not getting a fault light and why it's occurring with 0% throttle and not at 60% or more throttle as the fault troubleshooting tree states? Or is the tree misleading?

Thanks

 

[dousty]

That's a sweet kit Dan and looks like the sort of tooling you'd have for life. Well done!

On the tube end bead deal, in the past I have used a brake line flaring tool to put a flare or a double flare on a tube. Definitely not aircraft grade but would make your fuel line less likely to suck air.

However I suspect you won't have any issues as it is now.

any updates on this?

 

[dousty]

Nothing has changed at this stage. It has been sitting in my shed for a couple of months waiting on wheels and tyres. Got that sorted yesterday so back on the road again today.

 

[Workhorse]

Dousty,

It would be nice to see/hear it running and driving and how it performs. Would you shoot a few videos and post them?

Beauty build by the way...

 

[Wheelingnoob]

Very impressive! I'm amazed how quickly you got it done.

 

[dousty]

Thanks for the compliments fellas. Once I can sort out our video camera I'll grab some footage and share it with you guys.

Yep it was very quickly completed but I was working a 7 on/7 off roster at the time, so was more able than most to sink some decent hours into the task. I also spent a lot of time researching, planning on my white board and gathering parts before lifting a spanner. That's not normally how I roll but I'm glad I put that effort in first this time.

 

[cruisermatt]

That is a real pretty wagon my friend.

 

[dousty]

As requested.

Some photos of the 1HDFTE engine wiring diagram and the FJ62 diagram. I colour coded the circuits between the two diagrams to help me remember what I figured out. I did include a relay on the start signal circuit as the FTE start signal wire is heavier than the 60 series. Instead of drawing possibly higher current through the 60 harness I took it straight off the battery via a relay and used the standard 60 start signal to trigger the relay.
