It is a 2 piece. I might have found a way to work around it. I cold only be so lucky.
The Landrover pump has a hub on the shaft located by a key. The AHU pump sprocket I have will mount to the shaft and be located by same key afore mentioned. I need to make elongated holes in the mounting bracket because the LR IP has 3 round holes to mount the pump to the VW plate. The rear support comes off the LR IP and is replaced by the VW rear support allowing the pump to pivot for timing adjustments. It is like finding the HOLY GRAIL for M-TDI conversion, instead of spending a wad of cash to another pin head for his super pump. I want the little beast to run and drive.
I am building an AHU M-TDI for a Caddy and then for my Westy if all goes well. I was going to do the Westy first but the Caddy will be used much more.
I will let you know if I need the sprocket. I will check back in the next few days.
Thanks, David K
