NOTES:
* Matched set with pins, sold as assembly A32163A. Shown in three parts to illustrate disassembly.
+ See Page 8 for symbol regarding this information. Compressors below serial number 45330 were furnished with the no longer
available front bearing cover assemblies A30294A (2 and 4 cylinders) or A32162A (6,8 and 12 cylinders), and front bearing retainer
31885A (2 and 4 cylinders) or 33500A (6, 8 and 12 cylinders) without
oil hole. Former front bearing retainers (31885A or 33500A)
without
oil holes cannot be used with current front bearing cover assemblies A36240A (2 and 4 cylinders) and A36241A (6, 8 and 12
cylinders), as there is no way for oil to get to the bearing. If front bearing cover is being replaced, a current front bearing retainer
(31885A or 33500A with
oil hole) must be ordered also, unless one of these current styles is already being used. If a current front
bearing retainer, (31885A or 33500A, both with oil hole) is used with former style cover (A30294A or A32162A) having an oil hole,
remove orifice in cover (A30294A or A32162A) and replace with solid 1/8” pipe plug.
† Dams (Item 239) and screws (Item 245) are not needed when using VILTER’s patented joined crankshafts. In this design version
(introduced in 1980), two 6 cylinder or two 8 cylinder crankshafts are joined by a sleeve to form an inseparable 12 cylinder or 16
cylinder crankshaft. This specially machined sleeve eliminates the dams. This design is completely interchangeable with the former
design.
