OM617 Conversion with Questions/Bare with me plz. - ben2go - 09-14-2010
I am planning an OM617 conversion on my 1990 Mercury Blue Max Cougar.I wanna keep the OM617 A/C compressor an P/S pump.Here's my questions.
1)Will the OM617 A/C compressor handle R134A refrigerant?
2)If so,where can I find the correct fittings for the OM617 A/C compressor?
3)Does this compressor need oil added in through the hose fitting?
4)If so,how much oil and what type?
5)Will the OM617 P/S pump handle power steering and a brake hydro booster?
6)If so,where do I find the fittings for the P/S pump?
7)Is there anyway to mount the oil sum and pump on the rear of the engine?
This is just wishful thinking but,,,I can do the swap with the front sump.

ADMIN/MODS,
Sorry if this is in the wrong location.It seemed to me that fittings for the Benz A/C compressor and P/S pump would be more of an engine maintenance issue.Also my other questions seemed so as well.If I am wrong, please let me know.

Quote:2)If so,where can I find the correct fittings for the OM617 A/C compressor?There are none. Conversions put an adapter cap over the R12 low/high side ports.
Quote:3)Does this compressor need oil added in through the hose fitting?Yes. It has no reservoir of its own.
Quote:4)If so,how much oil and what type?Oil capacity depends on the volume of the system. Unless there is significantly more/less volume then the stock engine's system you should use whats specified for the Cougar.
Quote:5)Will the OM617 P/S pump handle power steering and a brake hydro booster?Yes. Even if flow is a little low, the booster has an accumulator.
Quote:6)If so,where do I find the fittings for the P/S pump?The return is just a hose barb, any 1/2" hose will work. A hydraulic shop should be able to get the metric fitting and make a pressure side hose.
Quote:7)Is there anyway to mount the oil sum and pump on the rear of the engine?No. The oil pump is in the oil pan. At most you'll be able to remove 2" from the lower pan.

Thanks.One more question.The hydro booster I am planning to use doesn't have,or I don't believe it has, an accumulator.Should I look for one that does have an accumulator?The one hydro booster that I set up on a friends Thunder Bird was a direct bolt on, except for the pedal linkage.It came from a 1982-89 Lincoln Continental.

All hydraulic boosters should have an accumulator. The one you have may have used an external one.

OHHHHH OHH KAY.It must have been internal,because it didn't have the little cylinder on the side of it.
