WOW has to be available SMG pump oring

dbottorf · 11-30-2023, 01:08 PM

2004 Z4 3.0 put a new SMG pump in this Z4 but had to use the used oring and it leaks. BMW says no listing. if you search the web for part number 23427571297 it comes with 3 bolts and an oring. Would hate to pay 800 for a new pump to get that oring. tried aftermarket rings but they leak....Any ideas for replacement??????

You could just install a used pump, https://www.ebay.com/sch/i.html?_fro...pump&_osacat=0

If you know the diameter and thickness it shouldn't be hard to find a replacement, make sure it's a Viton o-ring.
