Title: What wrench for CD-175 float needle valve ?
Post by: TurboFource on Thursday,October 17, 2024, 06:32:35 PM

What size is the darned CD-175 float needle valve wrench supposed to be? I don’t have a metric or standard wrench that fits well :confused: I am using a 14mm with a shim I made to fit it…. It seems I need a 17/32 ?

One of my 13mm's measure .515", other is .520". Looser than my 1/2" wrenches.  I just use adjustable on my rear upper arms and AN fittings. Nothing ever fits them good.

I have had to bend and modify various tools to fit difficult to access nuts and bolts all over the car.

Modification includes making spanners (wrenches) wider or thinner.

I have even bought 5/16" UNF bolts which have 13mm heads, and not 1/2" heads as you would expect.

It's a 5/16BS IIRC.

I can confirm it's a 5/16 BS. Thanks John, and to the OP for the timely post. That would have driven me nuts.

What the heck is that?

I didn’t think there were any Whitworth fasteners on these cars :confused:
