I think you've got some confusion with the 4BD1 vs 4BB1.

The 4BD1 also has an inline injection pump, it is the same engine family (4B ) as the 4BB1 and the engine blocks are externally identical.
Bore is the same, stroke is different but both are direct injection.

The 4BD1 has never had a rotary pump, the 4BE1 is the only 4B series I know of that had a rotary pump fitted.

Nope, just adding to the knowledge base.

Hi there,

I have a 4BB1 which needs an oil cooler replacement. I have the cooler but have been told I need the timing settings for the fuel pump, which has to be removed to change the oil cooler.
Does anyone have the info?

Cheers

Real easy.

There's a window on the front timing cover which is held on by two bolts. Undo those and rotate the engine until the strike mark on the timing gear (fuel pump drive gear) is visible.
At this stage, you can unbolt the pump and easily bolt it back up in the same alignment.

Blast from the past.

Anyone have this in their Series?

Hi guys- I have just bougt my first Landy, that seems to be an 81 Stage 1 station wagon, with messed up electrics(working on them), and a 4BB1 Isuzu engine. I am having dramas with the starter motor- it starts the engine if I short out the terminals, but won't work when I connect the battery. Starting to think it could be a 24v starter motor. Is this a possibility? and if so, what is the 12v one I need to buy?
Cheers.

Know I'm a bit late with the reply but thought it might be of use to the other 4BB1 owners. The 12v version starters for these engines seem a little difficult to find and expensive (Quoted about $980 from Isuzu about 5 years ago). If you are in need of a 2 bolt 12v starter to go on the isuzu bell housings, you can get an identical version made to fit a Daiwoo DC24 engine (used on a their lift trucks and excavators) Seem to be many available on ebay around the $300 mark. Total Source forklift supplies can also get them.
