Brake Vacuum Pump

Mechanic told me the vacuum pump is the main leak I need to consider fixing. Anyone messed with this. At work so I dont have the workshop manual with me. Quoted me at around $600. Found it on one site besides local land rover dealer. Not sure if its what i need because it has no pictures. He told me vacuum pump sits under the air cleaner. The truck is at the shop until tomorrow. Any suggestions on whether or not I should do it myself? Anyone have any good links for Land Rover Parts?

I think I narrowed it down

So I took apart the brake vacuum pump from the engine, looks like there is a sign of leakage. Mechanic told me that you have to buy the pump because there is no breakdown. This is correct for the break apart of the pump, there is a seal that mounts between the pump and the engine though. I think this is the culprit. Damn, I should have taken pictures.. Will post some when I replace the seal. Oh by the way it is not a standard size o-ring seal you would find in a kit. If this is the case, I will be saving almost $600. :buttrock:

Vacuum Pump Ordered

Looks like the seal wasn't the problem. It is the pump housing leaking. Wish I could find a rebuild kit for the pump instead of sinking $204.00 into a new pump. Anyone know where to find rebuild kits for pumps like these? The part # for the vacuum pump is LR009388 and the seal that seals it to CVT housing is LR017021.

LR2 has same 3.2 engine as Volvo S80 and the vacuum pump does appear rebuildable with Volvo kit:

Kit: Volvo OEM Rebuild Kit (31401556) $64 for 2 seals and new screws at local Volvo dealer.
Pump: Volvo OEM Brake Vacuum Pump. Part No. 31401152 & 31219778 (pump will actually show 6G9N-2A451-AF (or AG or AH). It's a FoMoCo (Ford) part made in Germany.

My LR2 pump is actually stamped with FoMoCo (Ford) 6G9N-2A451-AF.
I am original owner, so I know it came this way from LandRover factory.

Google/ebay for pics and prices and rebuilt pumps for about $150.
It looks pretty easy to replace.
Just pop-out the airbox, then remove battery and battery tray
2 bolts secure pump to top right-side of engine.
May need to remove Top Alternator Bracket (2 more bolts)
1-2 hours, maybe. Any mechanic or mechanically included person could do it -- way cheaper than LandRover dealer

Search Youtube for video titled: "2008 Volvo XC90 brake Booster Vacuum Pump Rebuild"
Things you have to remove to get to pump are a little different, but give good overview removing pump itself.
