Testing compressor?

[Gregory OConnor]

R&R is a term that auto mechanics use to imply REMOVE and REPLACE.
The replacement part could be in the shop the day the old part is
removed. In that case the old worn part is sent out as a core.

Parts sellers (Napa) use the term R&R to indicate REBUILT and
RETURNED , the exact part is sent out to a rebuilder and sent back
rebuilt to spec . There are some rebuilders that do a good job
everytime and yet some that leave returns to the averages and rush
the rebuild. Sloppy quality control give reman parts a bad name.
Many shops wont use reman parts because the labor to replace is not
billable to the bus owner/customer or the rebuilder.

A good parts seller like an independent Napa or in our area 'Colton
Truck supply' use several rebuilders for parts and best know of the
good from the bad RebuildShops as they see the returns against the
proven sucess. I like to order a part be rebuilt and returned. I
think the part gets more attention in final inspection prior to
delivery????? I can also get a clue from the rebuilder of why the
part failed (a worn out compressor in under 500,000 miles is a
result not a cause)

Since $1,200. vs $250. is typical for new vs reman, the only choice
for me is to make sure the remanufacturer is worthy of his work and
worth $250.

The compressors fail when it pumps dirty air past the piston and
wipe out the rings or the oil does the same. if the bearings are
shot also, it is most likely oil related. Be shure to oil up the
new install.

Nothing being typical with the bus repair you can be shure that the
harder it is to replace the compressor the more money you will have
saved.
