Graco 312068M Installing Lube Adapter, Installing Hex Clevises and Baffle Jam Nut

Repair

18.Using the far, top tie-rod, attach cylindrical spacer (114) to the right side of the assembly.

19.Attach one hexagonal spacer (113) to the other end of the tie rod. Do not tighten.

20.Attach one hexagonal spacer to each end of the bot- tom, near tie-rod. Do not tighten.

In the following step, the port holes need to be fac- ing down, with the cylindrical spacer (114) facing right.

21.Secure the assembly to a flat surface using two c-clamps, or other strong clamping devices, to pre- vent the assembly from twisting. The assembly will remain secured to the flat surface for the remainder of the assembly procedure.

22.With the assembly secured, torque the spacers against each other to 15 ft-lb (20 N•m).

Installing Lube Adapter

23.Push o-ring (121) into the inside groove of the cylin- der lube adapter (120).

1 Apply lithium grease to the o-ring.

24.With the lip of the adapter facing left, slide the adapter onto the left end of the hydraulic piston shaft.

Installing Hex Clevises and Baffle Jam Nut

25.With the hex-side of the baffle jam nut facing away from the hex-head of the clevis, spin the baffle jam nut (122) onto the hex clevis (117). Leave one to two threads between the head of the clevis and the nut.

26.Apply high strength thread sealant (124) to the threads of both hex clevises (117).

27.Apply primer (123) to the threads with the thread sealant.

28.Attach modified bushing (118) to the activator plate (119).

29.Insert the clevis (117) without the baffle jam nut (122) into the corner hole of the activator plate (119).

30.Slide the modified bushing over the cylindrical spacer (114) and screw the clevis (117) into the right end of the hydraulic piston shaft (104).

31.Spin the clevis (117) and baffle jam nut (122) onto the left end of the hydraulic piston shaft finger-tight, ensuring a gap of one to two threads between the baffle jam nut and the head of the left clevis.

32.Rotate the right clevis until the cross-holes form a vertical line.
