Thread: 4BD1 injection pump Governor?/Spring failed.

Hi Marc, Easy fix mate, they are just a return spring and nothing to do with the governor. Part number is 5157231340 for both of them. Cheers...Brian

Awesome thanks Brian/Bearman,

Is that a LR part number or something i could hopefully go to Isuzu truck parts with? (I will try Isuzu tomorrow either way)

Yes, it's an Isuzu part number so the truck dealer should be able to order it in, but from my experience they usually want to know what model Isuzu truck it is in. When you tell them it is in a Landrover they just look stunned and then say they need a model number. I just say "Okay 1988 NPR with 4BD1 engine"

the equivelent springs are in GJ kits they are a pain to change so while you still have a good one if you pull up at a repco they will be able to source you a pair of similar ones.

they are not critical spec items their primary job is to over come pedal and cable drag/pressure for return to idle. IMHO you're better off erring to the side of more tension than less an shorter springs over longer ones.

Any more pics of your adventures?

Thanks guys, popped into the Isuzu truck center down the road, the parts should be here Tuesday.

Now are there any tricks to changing them, From a quick look around inside the engine bay its hook the spring in to the front plate, then undo the circlip/splitpin and thread the spring loop section onto the post, put a spacer and repeat. Minimal space in there for all this :P. guess super long nosed pliers needed, or is it a "take the manifold off" job?

I have a bunch of photos, videos and timelapse of my time away :P Just need to sort through them and put them somewhere, Can link you when done if your interested.

You'll need a set of baby sized arms and some long nosed pliers - that's it.

It is a lot easier to do if you remove the intake hose and elbow from the manifold
Gives you a bit more space
