Newbie non owner (unfortunate mechanic) coach #172 - JayRMF - 07-02-2022

Good day folks,

I have been directed here by someone on one of the Newell Facebook groups who has told me you are all lovely and helpful people

I have been assisting with the recommissioning of coach #172. As far as I know it sat for quite a few years before being purchased by its current owner. The engine (8v92) was then pulled (unsympathetically, with a digger I believe) for a full rebuild, during which all the cut tails of hoses and wires were disconnected and discarded by the rebuilders. We’ve managed to get nearly everything reconnected and replumbed now, starts, runs, builds air, brakes work, levelling works, stops all as it should, but we appear to be missing a few pieces, where or when they were lost we do not know.

Would anyone here be able to advise on the hydraulic pump for the steering, we have two lines, one running forward I believe, the other from the reservoir but no pump, just what appears to be a fresh blanking plate fitted to the back (front I guess) of the engine.

Secondly, I believe there should be some form of oil pressure manifold on the passenger side frame rail in the engine bay, this has also been removed and is missing. Would anybody be able to advise on the senders/switches that were fitted to this rail, and where on the engine it would have been plumbed to, so that we can recreate the manifold and have a full set of working gauges and safety systems again.

Many thanks in advance, Jay (in the U.K btw, where knowledge and parts of older heavy diesels are slim pickings)[amoff][/amoff]

You are looking for clues concerning hydraulic connections rather than issues of the engine itself?
In any case, there is a service manual for Detroit 92 series here, if you need it:

Thanks for that Kaptain. Unfortunately what I’m looking for is a make and model or part number for the hydraulic pump for the steering, this being more specific to the coach build than the engine itself, the same I believe will apply to the oil manifold and this would be matched to the gauge set.

Richard gave us some great tips on how to search our archives that should help you find the answers you need. They are contained in this thread http://newellgurus.com/showthread.php?tid=6763

An initial search for you could be "8v92 and power and steering and pump"

On our 1986 #89 , the oil pressure sensors are located on the bulkhead of the driver's side engine compartment.  There is a sensor / sending unit for the dash pressure gauge , and a sensor for the warning light . I added the gauge at the top of the "manifold " , which h is a garden variety NPT fitting. Not sure if the coach you are dealing with is in the classic range , Michael will know .
I will try to get information from the power steering pump . Most , or all the parts are from the heavy truck /bus world .
