SP PILOT O-RINGS

[Couv]

Any old Pilot kits laying around?

I've never serviced a "real" Pilot so pardon the question. Other than o-rings, what requires replacing when servicing a Pilot?

...I just tried to upload the Pilot annotated diagram with no joy. If you need it (Edit) see this post:

I believe so but not 100% sure. I have an annotated pilot drawing, there’s a couple O-rings with SP part numbers that I don’t know what they are.

I have an annotated pilot drawing, there’s a couple O-rings with SP part numbers that I don’t know what they are.

Is it the drawing I linked to in post #32? I thought I labeled all of the o-rings (except a hose seal.) Which one are you missing a number for?

Item 55 which has a different SP part number than the others you annotated with -010’s

 

[Couv]

Item #55 is a SP -134 which is a -010. The reason the part number is different is because it is a different material (silicone.) Edit: The original would have been orange in color.

Does it need to be silicone? And 132 is also a -010?

I don't see why is must be silicone, EP and Viton were not popular back then. But silicone o-rings are not hard to come by. Again, I don't have a Pilot, but if the applications requires a harder or softer seal you'll have to take that into consideration.

Yes, a -132 is also a -010 (currently an EP 70)

Thanks for the help.

Selecting O-rings is an Fn Challenge.

Would this be the right selection for the annotated item 35, 002?

I would say not. That is a -901, you want a -002
McMaster-Carr (unfortunately McMaster wants you to purchase 75- I'll see if I can find a better deal.

Try here:
-002 CR70 - $0.80 : OringsUSA, OringsUSA

and if you decide to go with EPDM
-002 E70 - $0.40 : OringsUSA, OringsUSA

Yeah, I have used ORings USA for a few orders.
