IMPORTANT:
Avoid Damage! Soak new clutch or brake friction disks in hydraulic oil for 1 hour before assembling clutch or brake packs. Failure to complete this step results in premature clutch failure.
→NOTE:
Lubricate O-rings and seals prior installation.
[1] – Lubricate piston internal O-ring (A) and external O-ring (B). Install O-rings to clutch piston.
[2] – Lubricate bore and center shaft of clutch drum (C). Install piston to cylinder with piston tabs centered between bolt holes and over solid flange sections (D).
[3] – Lubricate and install two oil seals (E).
[4] – Install three interlock pins.
[5] – Install inner PTO brake actuator plate (F) with tabs located over interlock pin holes.
[6] – Install friction disk (G) with tang located over an interlock pin hole.
[7] – Install outer brake plate (H) and secure with snap ring (I). Ensure that snap ring is located in groove.
[8] –
→NOTE:
Install flat side of PTO brake spring retainer toward spring.
Install spring and retainer to clutch piston. Compress spring with PTO clutch spring
compression tool (J) and install snap ring (K).
[9] – Install four clutch brake plates (L) separated by three friction disks (M) to drive hub (N).
[10] – Install drive hub with clutch pack to clutch cylinder (O).
[11] – Grease three interlock pins (P) to hold them in place and install into clutch cylinder.
[12] – Assemble clutch drum to clutch cylinder with flange indentations aligned.
[13] – Apply thread lock and sealer (medium strength) to six socket-head bolts (Q).
[14] – Install bolts and tighten incrementally in a cross pattern to specification.
[15] – Lubricate seal rings and install clutch assembly to gear case. (See Install PTO Clutch in this Group.)
