    sorry man on most isuzu motors we hv no marks, i think whats best for u is to lift ur #1 piston TDC, valves rock #4 firing on #1, pump timing 8 degrees before injection then u'r ready

    no truck stated, NPR"? ELF or
    or forklift?
    no country, yes, later , AFRICA
    you dont have AFrica, isuzu dealers with books there?
    timing of what? CAM? pump.
    Cam timing is my guess, my guess is not timed
    fuel pump, so is CAM timing. (gears)
    if you google search this, you will discover
    vast persons asking, and zero anwers.
    (its not a car so data is harder to find)

    engine facts:
    The 4HF1 is an OHC direct injection engine of 4.33 L capacity. Peak torque is 285 Nm at 1,800 rpm, peak power is 116 PS (85 kW) at 3,200 rpm. Bore is 112 mm, stroke is 110 mm

    here is a vary pro grade web site, notice
    they cant find it either,
    they even ask (like i did)
    FULL DETAILS of the Vehicle, and the OP
    ignores, him, sad ,no?

    start you own post, better join a heavy truck form and ask,
    if you look here (search) vast posts on ELF
    and almost no answers.
    that is because major mech, on heavy trucks dont read this dribble. here.

    you're in good company, almost all posts here on huge heavy diesels never tell year or what truck it came out of....
    this is no heavy truck forum.
    is this an NPR heavy truck?
    Gcvr 25,000 lbs (11,000 kilos)????

    here is your engine, are you working at
    C or P? cam or this pump.

  • Anonymous Jun 06, 2016

    if I google, there seems to be no free
    manual on this engine, but googling
    can and may get better results.

Piggybacked now by 3 others.
and like all posts here on this engine
MOST never told
what country (1 told africa)
no year.?
no vehicle ,not once stated.?
NPR, ELF, tractor, fork lift , what>? must we guess.
and did you know engine data is listed only by
year, vehicle type(chassis class) then engine.
if you google all day, you see, what, ZERO.

and most just ask for timing
not once say of WHAT
the cam? the fuel pump, what?
must we guess all this, as is the case 100s of times here.

that is why no answers from 2008 to now

start you own post.? not piggy back, ?
or buy the FSM factory service manual from isuzu trucks.
then you scan the page and post it.?? be the first?
be a hero,

SOURCE: Cannot remove rear brake drums on Isuzu Elf 150 N-Series.

a brass hammer or punch really helps in this situation because you can hit the drum and the brass will take all the damage might want to consider buying one of these

Can anyone provide details of the electronic fuel pump used on the Isuzu ELF 4hf1 engine? Have problems with one that is not supplying fuel to the injectors/engine.

some times the electronic fuel pump has such draw on the fuel lines from the tank or filter ,older fuel lines collapse , if the engine starts and stops that may be yr problem ,a temp fix is to install 1/4 inch springs into the lines until they are replaced with non collapsing hose

I can't find the timing marks of an isuzu engine 4hf1

Timing is aligned with bolts through holes in the drive wheels under the timing cover and a mark on the crankshaft remove the timing cover turn the crankshaft until the mark is at the top. the engine has treaded holes behind the drive wheel's get bolts(12 or 13mm head metric tread 4 or more ins long) push them through the holes in the wheels and screw to the engine this is alingment in an isuzu engine
