IRC, the center digit denotes the pump head size. In the case of your example part number it's a 9. If it were a 0 then it'd be a 10mm pump, 1 would be an 11mm pump, and 2 would be a 12mm pump.Whitbread said:Does anyone have a chart on how read the p/n's on bosch ve pumps? More specifically, what numbr's denote head size. I remember reading it somewhere but I can't find it for the life of me. Specifically a number like 0-460-494-213. Is the "0XX" number inside of the circle head size?
Thanks as usual
Fly appreciate the info.FlyTDI Guy said:For the ALH, it's basically like half a timng belt job. To get the pump off you need to bring the crank to TDC, pull the vacuum pump, lock the cam, loosen the TB tensioner, crack the cam pulley loose, remove IP pulley, unhook and remove IP pump. The setting up means re-install new pump, swap IP pulley onto new pump, re-hook up HP lines, harness and fuel connections, re-time as you would a belt job. Other than the hardware swap, you retime as spelled out in Drivbywire's instructions available here. You'll need the TB tools to lock the cam, pin the IP, counter-hold the cam pulley and tighten/loosen the TB tensioner. If doing it for the first time, it helps to have a mentor at hand. Good luck and enjoy your new pump...

How many miles is on your car?leon10tagg said:Shadow I suppose then the 11mm with R520s should be able to supply enough fuel to make 280 to 300 with the right supporting mods.
Anyway whilst stripping the car to do the TB change and fit the 11mm I noticed wear on the cam and followers....so work has stopped for now
So now I am on the look out for an uprated cam.....any suggestions? I have heard mixed reports about the Dbilas 260 cam, which appears to run with the standard spring rates?
Only 117k miles. I have since pulled the sump and its totally spotless and so is the cam cover area.....no sludge at all. The oil in the car has been changed every 5/6k miles since I first bought it nearly 8 years with 5k miles on it. The only issue I can think that may have caused this is that the car gets driven hard all the time and quite a lot from cold. So I'm at a loss to understand the wear on the cam and marking on the followers?Dankcorey22 said:

Mojo I had hoped that the cam would fit using the standard type followers, as I don't want to do any head work at this stage as I need to get the car back on the road. Its all been a bit unlucky as the impreza's engine is stripped awaiting an uprated turbo and the A4 1.8T is stripped as I am currently cleaning the underside and prepping it for painting. So if the cam would fit straight in without to much work it would suit better at this time.mojogoes said:
