It does need to be adjusted to get the right vacuum and also I don’t really see the need to disconnect the wires because there is enough room to make the exchange without doing that. You can apply 12 volts right to the lugs when testing for vaccuum
Ok I can confirm my impeller is not broken. Everything looks good to be honest. the fins look slightly warn compared to the brand new impeller. The new impeller fins are flush with the rotating piece. The warn piece fins have about 0.9mm clearance when the fins are pushed all the way in. Hopefully this is the difference cos the system was still working in mine. Just weak and struggling will update again once back in the car.
@@hristovargolomov2999 Hi, I am Bloom0to9. Basically, the connection lines @ 00:25 were not sitting properly and air is escaping. Maybe I should make a video

If I'm not wrong, you need to test to see if it's getting 3 bars of suction. Adjust the screws accordingly to achieve 3 bars.
thanks for posting :) seems very easy. I have the impeller. I will attempt this once weather clears up. Cheers

Without pressure test?
Where do I get the impeller key for my new pump?
А как можно купить у вас эту запчасть на помпу???
Will it work on a w124 250D 1987?
Hi there, it's not on our list of vehicles affected, do you have the part number from the impeller housing? - Georgina, X8R Ltd
No mention of pressure calibration. This video is incomplete.
Can you buy the entire motor?
Hi there,
No sorry we do not sell the whole motor unit
