Need to get some ordered today, thought I had the information at work but cannot find it....tried a search with no joy
The main pump head o-ring seal it's 68mm O.D. with a 2.5mm wall isn't it?
edit: soem googling has netted me Zexel part number 146600-0000 which is quoted as being 60mm x 2.62mm
Not sure if 60 is the ID or OD???
Good to know. Did you find a supplier? How much are they?
No turns out that the internet is wrong - as the bore on the pump housing is near 68mm - so the bag I had my last lot in with the faded handwritten dimensions of 68 x 2.5 may well be what I have been using
I bought 25 from my local bearing stockist - for less than £5. This was 3-4 years ago, had no reported failures.
