hi guy ,
bit of a problem which i need help with iam restoring a bj40 landcruiser and while i was cleaning the engine in my innocence i took the fuel pump of .........now i know i have mess with the injector timing :doh: shouldnt have taken if off anyway ...now i need to retime the injection pump and i am having trouble getting information on this any help would be much appreciated
 
The FSM (Factory Service Manual) manual explains how.

They are available here (Free) as a PDF:

You can probably get it close, but its probably best to take it to a speciality diesel shop and have them do it. Timing a diesel is not as easy as timing as gas. Call around your area, you might have someone who knows Toyota diesels. It will probably take around 2 hours.

I am lucky in Cranbrook. Our local diesel shop had the contract for all the mine trucks here. He has been working on Toyota diesels for 25 years. When my girlfriends 3B came in he, had a big smile. He timed it, and then spent two more hours looking and tinkering for free. If your in the area I would recommend him.

Cheers,
Nick

I've never timed a deisel. I didn't even know it could be done. I HAVE let my tank go dry and the effect of that might be similar to your removing the fuel pump. It introduced air into my fuel lines and I had to keep the engine revved high for a while to drive out the air. I also loosened the fuel lines at the engine to spray fuel out until it looked like no air was there anymore and then re tightened them, one at a time. After that, things worked smoothly enough for me.

Letting your tank go dry will not mess with your engine timing (as far as I know anyways).
Do a quick search. I have covered how to reprime a 3B several times.
I know you have a 1HD-T, but the proccess is the same.

Cheers,
Nick

If you only removed it ,you just put it back in the way the splines allow and then adjust it till the alignment marks on the pump flange and timing gear case.

Your 13BT should be the same Nick .

In short,it can only go back on one way

The 1HZ and 1 HD=T have the alignment marks on the belt pulley instead of splines but they also have the alignment marks on the pump and timing case.
 
you will have a matchmark on the pump to the housing. but one thing since it has been on for while you might see where the bolts used to sit in relationship to the rotation. Might be stained or noticeable. If you line that up it should work.


if it doesn't you need a standpipe on the #1 outlet and have to go thru the timing procedure.

next time make a mark with marker...

Aren't there timing marks on the teeth on the gears?

Yes,diesels always have some way of alligning the driven gears in the timing case for engine assembly but when the 3B pump comes out the pump gear(automatic timer) stays in the timing case and the pump is aligned by a slot on the pump shaft when you replace it.

Ok, I thought that the gears were taken out.
 
All diesel fuel pumps can be "spill timed" if you need to fit them without timing marks etc
-remove the delivery valve from no1 cyl pump unit on the injector pump
-fit a short (3") inj line to no1 pump unit as above
-refit fuel supply line to pump and prime with hand primer
-turn fuel inj pump in normal direction of rotation until fuel flows out of no1 inj line (with dummy line fitted and delivery valve removed)
-keep turning pump until the flow of fuel stops
-the instant the fuel stops is the point of inj (should slow to a drip then stop completely)
-turn the motor over until no1 cyl is at TDC COMPRESSION STROKE
-most diesels run between 3-10deg advance check the book or look for marks on front pulley etc
-fit the inj pump and them replace the delivery valve!
