CYLINDER AS 3535583 - Caterpillar

(1) Install shaft assembly in housing as follows: a. Install spacer (3) and spring (2) on shaft assembly (1).b. Install the assembly in the housing. Turn spring (2) until it engages correctly with pin (4).c. Install handle (10) on the shaft assembly (1). Turn shaft assembly (1) upward and install pin (13) so handle (10) can rest on pin (13).d. With the shaft assembly and handle (10) in contact with pin (13), install plate assemblies (5) and (6) on the shaft assembly.e. Remove pin (13) to release the handle and let plate assemblies (5) and (6) move to the "shutoff" position. A 0.08 mm (.003 in.) feeler gauge should not pass between each plate assembly and the housing.f. Remove handle (10) and install spacer assembly (12), pin (13), the gasket, cover assembly and handle (10).(2) Spring.(3) Spacer for spring (2): Bore in spacer for shaft ... 20.80 0.25 mm (.819 .010 in.)Diameter of shaft ... 18.94 0.02 mm (.746 .001 in.)(4) Pin.(5) Plate assembly.(6) Plate assembly.(7) Hydraulic cylinder must be installed before the air shutoff can be installed on the engine. Put the air shutoff group in the "open" position and install the gasket, flange and cylinder with cylinder shaft (15) between the spacer assembly in the shaft lever and spacer assembly (16).
