| Notes on self-locking nuts and bolts | All models | |
1 | Compressor removal | ||
2 | Unscrew cylinder head bolts and remove cylinder head (10). | Use plastic hammer to loosen cylinder head if it is seized. | |
3 | Remove cylinder head gasket (9). | ||
4 | Dismantling cylinder head (10). | ||
5 | Remove side cover (2). | Remove gasket (3). | |
6.1 | Remove coolant line between the two cylinder liners (8). | Applies only to 2-cylinder compressor. | |
7 | Remove the cylinder liner (8) bolts and extract cylinder liner (8) by pulling upward. | ||
8.1 | Remove attachment bolts from compressor housing (1) | Applies only to 2-cylinder compressor. | |
9 | Remove circlip (11) from piston assembly (13). | ||
10 | Press out wristpin (12) from the opposite side and remove piston (13) with wristpin (12). | ||
11 | Unscrew connecting rod bolts and remove bearing cap. | ||
12 | Remove connecting rod (14). | ||
13 | Remove cover (4). | Remove seal (5) from cover. | |
14 | Remove compressor crankshaft (18). | ||
| |||
15 | Remove circlip ring (19) from cylinder roller bearing (20). | ||
16 | Remove cylinder roller bearing (20) from the compressor housing (1). | | |
17 | Remove inner race from cylinder roller bearing (20). | ||
18 | Drive bearing liner (16) from bearing flange (15). | | |
| Inspecting | ||
19 | Clean all components and check for wear, replace as indicated. | ||
| Assembling | ||
20 | Drive bearing liner (16) into the bearing flange (15). | The oil orifice in the bearing liner must be aligned with the oil passage in the bearing flange. | |
| |||
21 | Drive the cylinder roller bearing (20) into the air compressor housing (1). | | |
22 | Install circlip ring (19). | ||
23 | Insert inner race within cylinder roller bearing (20). | ||
24 | Install crankshaft (18). | ||
| |||
| |||
25 | Place seal ring (5) in the cover (4), then install cover. | Replace seal | |
26 | Position bearing inserts (21) in the connecting rod (14) and connecting rod bearing cap. | Be sure to position bearing inserts correctly. The oil orifice in the bearing inserts must be aligned with the oil passage outlets in the connecting rod. | |
27 | Install connecting rod bearing cap and connecting rod (14) on the crankshaft journal (18). | Oil crankshaft journal prior to installing. | |
28 | Start connecting rod bolts by hand, then tighten down. | 2-cylinder compressor only: The connecting rod for the vertical cylinder must be installed on the same side as the drive gear. | |
| |||
29 | Install piston (13) on connecting rod (14) and press in wristpin (12). | Oil wristpin prior to installation. Pistons and cylinders must always be replaced as a set. Both components must be from the same dimension group. | |
30 | Install circlip (11) in the piston (13). | Ensure that the circlip seats securely in the groove. | |
31 | Use piston ring compressor to compress piston rings. | Start by applying oil to piston contact surfaces within the liner. Arrange the piston rings with one gap below the wristpin bore and the ring gaps offset at a 45° angle. | |
| |||
32 | Slide the piston (13) into the cylinder liner (8). | The cylinder liner and ther piston can only be replaced as a set. Both components must be from the same dimension group. Apply sealant to the cylinder liner seat surface prior to installation. | |
33 | Install cylinder liner (8) on the compressor housing (1) and screw in bolts to tighten. | Tighten bolts in cross pattern. Applies only to 2-cylinder compressor. As a supplementary operation before installing the vertical cylinder liner, insert attachment bolts in the sockets within the compressor housing. | |
| |||
| |||
34 | Assembling cylinder head (10). | ||
| |||
| |||
35 | Position cylinder head gasket (9). | Use a new cylinder head gasket. Pay attention to installation position of cylinder head gasket. | |
36 | Install cylinder head (10) on the cylinder liner (8), the screw in cylinder head bolts to tighten down. | Note positions of alignment studs. Tighten cylinder head bolts in cross pattern. After engine has reached normal operating temperature, loosen bolts and then retorque. | |
| |||
37.1 | Install side cover (4). | Use new seal (5). | |
38.1 | Install coolant lines between the two cylinders. | Applies only to 2-cylinder compressor. |
