Fixing a leaky vacuum pump
https://www.rkxtech.com/collections/vacuum-pump-repair
Youtube has an excellent video to show you how. Took about an hour. The silencer canister is a bitt fiddly. But hey, no more leaks.




Don't know how it develop in last years, but a generation ago, I found the same Bosch vacuum pumps on Mercedes, VW and Peugeot.
So when I needed diaphragm, no problem to find it on JY.
Same was posted on W210 forum where MB would not sell Power Steering pump seals, only whole unit$$$, when BMW - using the same PS had rebuild kits available.
