Author Topic: WTB: ALH injection pump hub (Read 5517 times)

As the title says, I'm looking for the hub off of an ALH injection pump. I already have the rest of the sprocket. Thanks in advance!

I still need this.

The ALH has a 2 peice sprocket on the injection pump. The center peice that goes onto the injection pump is proving to be difficult to find.

Please?

The hub itself comes with the TDI injection pump assembly as a whole. It is indexed to the pump shaft from the factory and does not have its own P/N though Bosch from what I've found as I thought about getting some more and doing Cummins pump setups for people wanting mTDI's.
I had to get a core TDI pump in order to get the hub itself. Supposedly there is a Bosch special order where you could source it through but the conversion figure for price was something like 150.00 alone + the shipping from Germany.
Glad I got mine for the 4bt pump

Set is really fly though once up and going as I'm experiencing now.

Buying a used pump is the direction I'm heading with this one. Perhaps I can use the rest of it as well.

Well...even if you don't use the rest of it...parts of it could be sold. the 10mm head could be sold to as and IDI upgrade for someone. The top portion of the electronics could be sold as well as the quantity adjuster assembly, etc. to someone needing a replacement, etc.

Options...

One thing I'd like to find out is whether or not the electronics are interchangeable between the earlier AHU pump and the ALH pump. If so, I wouldn't mind picking up an 11mm ALH pump and using the hub for my IDI and then the rest of the pump for my TDI.

I don't believe they are ... Early AHU and 1z pumps used a 7 pin connector while the later ones I believe used an 8 pin connector... From there....not sure...but I know that of the basic electronic differences between the pumps... might be something to dig on Fred's about. I can't say whether items like the fuel temp sensor, quantity adjuster, etc. are different between the two. I just know the PIN connections between the models are different when going from AHU/1z to ALH, etc..
