In the case of compressors with a sleeve bearing either front or rear, place the two small seal rings in the counter-sunk holes in the crankcase. Caution: An end cover gasket must not be used. Place the O-Ring seal in the groove around the flange adapter or the end cover, and affix the thrust washer. Install the flange adapter or end cover in the proper position as marked before disassembly, taking care not to damage the sleeve bearing.Secure the flange adapter, front or rear end cover to the crankcase by tightening the four cap screws. See note below for torque. For cast iron flange adapters, torque the four 7/16in. cap screws to 38-45 foot pounds. For die cast aluminum end covers, torque the four 7/16 in. cap screws to 25-30 foot pounds. All end covers using 5/16 in. cap screws or stud and nuts are torqued to 15-18 foot pounds. For through drive compressors with a cast iron end cover, torque the four 7/16 in. cap screws to 25-30 foot pounds.Pistons and Connecting Rods
If new wrist pin bushings are to be used, they should be pressed into the connecting rods so that the oil hole in the bushing lines up with the one in the rod. The new bushings should then be reamed or honed to provide between .0001 in. (.00254 mm) and .0006 in. (.01524 mm) clearance on the wrist pin. Position the connecting rod in the piston and press in the wrist pin.Pistons installed in compressors manufactured prior to November, 1976, will have the wrist pin secured in the piston by a lock wire extending through matching holes in wrist pin and piston boss, anchored in a hole in the side wall of the piston. If the original pistons are used the wrist pin must be pressed in so the hole in the wrist pin aligns with that of the piston and secure same by inserting the new lockwire through the hole in piston and wrist pin and lock the wire by snapping the short 90° section into the lockwire hole in the bottom of the piston.Compressors built after November, 1976, will have the wrist pin secured by Teflon buttons in either end of the wrist pin, allowing the wrist pin to float. The Teflon buttons pc. no. 292392 may be used with either new or old wrist pins. The later design pistons have two rings above the wrist pin and one below. Install the piston rings in the correct location with the ring pipmarks up. Stagger the position of the ring gaps. Prelubricate the piston, piston rings, wrist pins and connecting rod. Unloader
A new unloader kit should be used when rebuilding. (Figure 13). (Piece Number 279615). The unloader pistons in the kit are prelubricated with a special lubricant piece number 239379 and need no additional lubrication. Install the unloader pistons in their bores being careful not to cut the o-rings or distort the back-up rings. Position the unloader plungers in their guides and slip
