So I know the tachometer on my FJ62 won't be compatible with the new engine, and I need an alternative. Started looking around, but I'm not sure I know what I'm doing. Why doesn't the OEM tacho work? Are there diesel-specific tachos? Where will it read the rpms?

Thanks in advance, new to diesel, it's like voodoo right now.
 
I wish I could help. The 1HZ that went into my truck went into a HJ60.

What's your story again. What engine did you transplant?
 
The tachometer on the BJ60 reads from a Hall sensor on the bellhousing. The gasser tach won't work because they almost all rely on a signal from the coil and there is NO coil on a diesel.
There are also tachs available that work off the altenator and the injection pump.
 
:beer: Even though it does not work, the swap should be a simple one. What engine did you implant?

Pics?
 
My tacho .. . in my 2H ( original engine ) works with alternator, and is very simple to connect. I'm not sure right now, if my tacho are difernt of your tacho, but in my case it's only manage 5 k rpm .. yellow line in 3500 and red line in 4 k.
 
Is your tach original, factory?
I've got a tach (thanks Bob Bancroft!) but not sure where to connect...

I used dist parts from my old 2F engine to make a tach pickup:

Dang, FLcruiser, that's cool. Be sure to tell woody so he can link it from his tech page.

Henry, there is a tach that picks up pulses in the fuel injector line, but the display is digital. I posted the link once on these pages, maybe do a search. There is an Autometer gauge that picks up the engine speed off your alternator and can be calibrated manually to match your pulley ratio. Look at Autometer's website/

Why did you put on a 62 steering wheel? I like the look of the 60 steering wheel myself. The dash is clean though. :cool:

:beer:
 
1985-87 60 series steering wheel also. The wheel itself is the same as the 70 series, it's the center section that changes.
 
This is the wheel out of my 1988 73 series.:cool:

Hello, I own a 1980 HJ47 with a 2H engine. I purchased a used tach from Specter which looks exactly as you describe. The tach has a 5 wire clip. Three wires are connected to individual screws 1 - black, 2 - back yellow and 3 - red. The remaining two enter the housing and provide power to the light 1 - white black and 2 - red black. I am unable to find any specs on the alternator connections yoy mentioned. My alternator is a replacement with a stud terminal (B) and terminal connections F, E and N. Could you help me with you waring connections?

Thanks
 
Reviving an old thread as i have the 1HDT diesel engine and the tach belongs to the 2F petrol. I did manage to find a used 12HT diesel tachometer but its 24V not 12V.
Any idea if there is a work around for that ?
