1. Remove the wire harness from the sensor and the
sensor from the well.
2. Loosen the cable clamp nut.
3. Apply a thin coating of heat conductive compound
(YORK Part No. 013-00898-000) to the sensing
zone of the replacement sensor element.
tight, and then wrench lightly while pushing the
sensor toward the bottom of the well. Ensure that the
sensing zone of the sensor element lightly contacts
the bottom of the well. Inadequate sensor to well
contact will give false readings.
5. Hand tighten the cable clamp nut. Connect sensor
plug to proper wire harness.
The compressor oil strainer tube is rolled into a hole
in the compressor housing and therefore is not readily
removable in the field. However, it can be replaced.
Refrigerant must be recovered, pressure relieved and oil
drained before removing and replacing the oil strainer.
Remove the .375-18 NPT pipe plug located to the left of
the heater well. Drive the oil strainer from the housing
using a 1/2” drift pin. (Loctite retaining compound 675
seals housing/tubing interface).
Thoroughly clean and remove oil from hole and pipe
threads in housing.
crankcase oil heater / oil temp sensor
The crankcase heater is located on the oil pump end of
the compressor. The heater is located within a well in
the compressor housing. It is not in direct contact with
the refrigerant or oil. To replace the heater, remove the
conduit and the heater wires from the terminal box. Pull
the heater from the compressor (See Fig. 20). It may be
necessary to remove all or part of the defective heater
with a Ø .626 - .637 inch (16 mm) drill bit. If so, use ex-
treme care to avoid damaging the well in the housing.
When installing the new heater, coat it with heat conduc-
tive compound (YORK Part No. 013-00898).
The oil temp sensor is in a well, on the side of the com-

Apply retaining compound (YORK Part No. 013-01752,
Loctite 675) to clean surface of tube of replacement
strainer that engages housing and insert tube into hous-
ing. MAKE CERTAIN TUBE DOES NOT BLOCK
VERTICAL OIL HOLE IN HOUSING. Roll copper
tube into housing to tighten.
Clean pipe plug with an approved safety solvent (YORK
Part No. 013-02899, Loctite 7070). Apply primer
(YORK Part No. 013-01753, Loctite N7469) and allow
to dry. Apply thread sealant (YORK Part No. 013-02023,
Loctite 565) to pipe plug and reinsert/tighten pipe plug
