Title: Water Pump Studs
Post by: Switchback on October 22, 2020, 04:53:08 PM
Ahoy everyone!

I'm replacing my Oberdorfer water pump with the same, and I've seen many threads on this. My question, however, is what would you recommend replacing the studs with? I've seen anywhere from stainless steel bolts with the heads cut off to silicon bronze studs. The previous studs are garbage. Any help would be great! Thanks!

Check with Ken Kloeber. He has a kit that worked well on mine.

Noah, what is included in the kit? Do you think it is temporarily (2 days of sailing) okay for me to get M6 stainless bolts, cut the heads off and apply anti seize?

Should work fine! Use nylock nuts. Basically same as KK's kit.

Yah need double-ended studs to have a shoulder to tighten them down against the gear cover.  If not there's a possibility (very slight) that when nutting down the pump the stud could back down into the gear cover, potentially interfering with the drive gear on the camshaft.  Slight possibility, seeing that you're lock-tight ing them in, but I'm just saying.....

Negatory mon ami.  Not the same.

They're unequal, double-ended, 6mm-1.0 x 32mm studs (avail at a good hardware store like most ACEs, but not in stainless.)
