Thread: 4BD1 Bell Housing?

Murray (Rijidij) has posted both on here. IRC all the 4B series engines have the same bellhousing bolt pattern.

Thanks for that Isuzurover, that is all I really needed to know.

Cheers Paul

This is a standard 4 speed bellhousing.

Hey guys,

Does anybody have a photo and or the dimensions for the bell housing on a standard non Landy 4BD1?

I am trying to find out whether they have the same bolt pattern as the 4BB1 in my Series.

It would be good to know if I could upgrade to the 4BD1 engine

Cheers Paul.

Paul wanted to know dimensions of the Isuzu (not Land Rover) bell housing. Murray's pic shows the Land Rover bell housing - Isuzu has a different bolt pattern.

These 2 pics show the Isuzu bell housing (the bottom bolts are not visible due to angles pics were taken from).

Woops........missed the 'non'

I do have a truck bellhousing, but it's buried under too many other parts to get to at the moment.

Have a read through here:
Isuzu 4BD1 Bell-housings. - Page 2 - Cummins 4BT & Diesel Conversions Forums

PCD for the Isuzu bolt pattern is 425mm, bolts are M10, 405mm internal diameter.
