930 piston squirters diameter

[Steve G]

Has anyone out there got some piston squirters they could measure please?

I'm interested in these following part numbers

930 101 015 00 Nominal
930 101 015 50 Oversize

Many thanks in advance
Steve

if I remember correctly you have to measure the bore after you remove the old one.
if you have to go oversize you have to drill the bore out.
mine were NOT easy to get out.
take my advise. pressure test them. if they are not bad leave them alone.
I ended up shipping my case and having a machine shop put them in.
they are just a ball and spring seat. nothing to go bad but possible clog.

there is/was another company out there that made a glue in squirter. search for them. they also have a video on replacing them .

oh, to make things worse. i had two that broke in two. part of the body was stuck to the bore.

Thanks, i took mine out today, they came out super easy, job lot about an hour.
I have zero bore damage as i didn't drill down at all.
I just want to know what is the diameter of the 930 squirters and whether it's the same as the SC. This is why i'masking for someone who has some lying around to measure them.

Yeah, i'm going to give these things a wide berth.
I've read (not wanting to believe everything ) that the cracking pressure when tested was around 3psi against the porsche value of 40psi, thats a massive difference......like cavernous...
I will replace mine with porsche units, just pondering to fit 930 units as i have a 930 pump in the case.
If these really do open up at 3psi then they are pretty pointless. The whole point of the valve is to maintain oil pressure at the rotating assembly during low pump output.
As for the rebuildable aspect, unless you plan to be regularly opening the case it really is of no consequence.

So anyone out there have a 930 squirter they can measure ???
