Well, we are done with our second in-frame on our 8V92TA. It runs like a charm now, but I'm having starting problems. We've traced the problem to a Kysor pressure switch at the fuel filter. I have bypassed the switch temporarily, as we really wanted to get out of the shop, and they did not have a replacement in stock.
Now I'm having trouble finding one, and I thought I would call on the collected wisdom of the group to help.
The switch is marked Kysor Cadillac (Kysor was in Cadillac, Michigan) PressureStat 33130-10 NC. PressureStat is just their trade name for a pressure switch/sender, NC stands for normally closed, and -10 is, I think, the pressure setting, but I am not sure if that is in PSI or Bar.
Kysor Industrial was split up years ago, with parts going to Kysor HVAC (air conditioning), Borg-Warner (fans and belts), and Medallion Instruments (gauges and senders). As a side-note, the old Kysor plant in Cadillac is now a SuperFund site. So Medallion is the place I would need to go for a genuine "PressureStat" replacement, but I could not find a cross-reference to this part number (33130) anywhere. PEDCO gave me a "new" part number of 1042-08240-10, which looks right (single setpoint, 1/8" NPT, single screw terminal, grounding type, normally closed).
Enough of the background, here are my questions:
(1) What does this do? It's not on my schematic, so I can only guess. And that guess is: it prevents the starter from cranking once fuel pressure has built to the indicated setpoint. This prevents you from trying to crank an already running engine, and it also cuts out the starter once the engine is running. Does this sound correct, or am I all wet?
(2) What is the correct setpoint for this switch? Would it be 10psi, or 10 Bar (about 145 psi)?
I'm asking because Cole-Hersee and others make similar switches, and it will be much easier to locate a part if I can cross-reference it to a more common manufacturer. If I know the pressure setting, I can probably find a fuel pressure switch at NAPA.
Any thoughts?

Put a pressure gauge on that port and find what it is with the engine running. Interpolate from there as to what the switching pressure might be, but doubt it would be anywhere near 145Psi.

Wells PS30 pressure switch N/C opens at about 10 psi - alvailable almost anywhere autoparts are sold
use on many many Chrysler cars - button terminal take female push connector
or Cole Heerse 8643 (same switch)
rate to 150 PSI |

I don't know for sure, as Kysor made a lot of products (my father in law worked there), but their main product was radiator shutters and the controls for them. Medalion had an instrument plant in the Grand Haven, MI area. I purchased some boat instruments there years ago. I am not sure the plant is still open.
If I were to guess, I'd say someone used whatever switch they had for the purpose. I agree with Joe, you probably don't have a 145 psi function on your coach outside the transmission and power steering systems. HTH

Sean,
In my book, you're not "all wet."
Same switch on my MCI, same function, (its double pole with one side grounded)and it's psi and not bar. 8-10 would be good.
By the way, anything obviously wrong with your engine?
Regards,
George

Sean,
This same subject in very long string was on MAK a few days ago. Don't remember the exact Subject name. |

Have you tried calling bus supply places? Here are two: http://www.muncie-baker.com/history_muncie_transit.htm

Also, if you have the Neoplan part number I can look it up in my parts book from Mohawk. |
