Fuel pump injection timing. Bosch ve 170 BT 4000
Hello everybody,
I am inmersed into pump timing adjust after rebuilding completely my old cylinder head.
I have usted the Bentley manual values for timing but without success, I started on 0,80 mm before TDC, later 0,86...0,90...and actually settled on 1,00 mm.
The van power is very well and compsumtion is very good but, warm starting without glow plugs is not as It should.
Can anybody give me a clue?
My engine is a 1.6 td JX, mechanical taps.

There's a really comprehensive guide to setting the injection pump timing here:

Is it the same with the cold start advance being set when it is warm?

Thanks for the guide clift_d!
No Oldie but goodie, engine starts in two crank turns...better but not as It was and should.
It used to start running in half a turn before I disassembled the head.
As far as I searched typical value is around 0,9 so Will check out the guide clift pointed and see what can I find.

Have a look at your leak off pipes if air gets in or fuel escapes it can be a real pain to start ,just had a issue with mine ,one of my pipes felt damp, in the end one of spouts going in to the top of the injector wasn’t fully home.

Fuel pipes are ok jhollies, only issue i can think off is the alignment marks of crank and fly weel, camshaft is ok with Its locking plate, and readings on pump are quite clear.
In my van mark in fly weel is just one triangled small mark. But on the housing for the clutch is like a two peaks mark, one of them higher and closer to the fly weel wich I take as the exact point for TDC.
I will post a pic asap.
I really think I am not matching crankshaft and fuel pump.

The timing mark is the triangular indentation on the clutch cover.
Seems to me that you aren't on the correct timing mark hence my query as to the effect of the cold start advance lever being applied.

Precisely the mark in clutch is clear to me since it is like that you show me now.
Maybe you know about the other mark I say ( of course for the strange shape It has...not for what is... ) to wich you have to align with this one on the clutch.
I have searched on images many places and never saw another like mine.

Make sure that you have not got the timing belt 1 notch out - very easy to do. The new belt is very tight on the fuel pump side when you are setting it, don't go back to to the easy notch go to the hard to get belt on one. Belt needs to be tight on the pump side, top and bottom before the tensioner is applied.

You can see the clutch cover timing mark at the top right - it should line up with the pointer. (Pic borrowed from lloydys post here http://forum.club8090.co.uk/viewtopic.p ... k#p7903525 ) It isn't difficult to get it in the centre without the pointer if the pointer is missing. Cardboard tube with a wire across the diameter which will fit in the hole could be used if you cannot judge it by eye.

Re: Fuel pump injection timing. Bosch ve 170 BT 4000
No doudt the Belt is not missing a nocht,
Ill try yo take a pic of my pointer and show you how strange It is, and looks original untouched from factory.
Anyway i can take as a good reference mid point of circumference of the checking hole, can't I?
That woud make a slight difference on my timing I think.

Re: Fuel pump injection timing. Bosch ve 170 BT 4000
Jajajajaja!!
I am not centered at all, close to run well but out of measures.
Thanx man, I Will put thinx together and give the last try when i get back home.
Or may be not cause I found this weekend that the cylinder head is damaged far beyond repair, got cracks on pre-com-chambers and heats slowly on slopes. I'm changing It asap when got the time.
Thanx and have to say is a GREAT Forum with great information and cool people.
