21.Repeat Steps 17 through 20 with remaining cylinders.

22.Rotate motor by hand. Motor should rotate without binding.

23.Install mounting flange (216) and gasket (226) on front of motor housing. Make sure notches on both parts are aligned.

24.Lightly lubricate ‘O’ ring (5) and install in groove on motor adapter (6).

NOTICE

•‘O’ ring, item 5 listed in step 24 refers to part number 51459 as shown on winch assembly Dwg. MHP0157 on page 40. This part must be placed between mounting flange (216) and motor adapter (6).

25.Temporarily install capscrews and nuts finger tight to retain motor adapter (6).

26.Install eye bolts (213) and vent cap assembly (210) in motor housing.

27.Ensure oil drain and level plugs (225) are installed.

Reduction Gear Assembly

Refer to Dwg. MHP0157 on page 40.

NOTICE

•It is important to maintain a clean work area when reduction assemblies are reassembled. During reassembly clean each part thoroughly and lightly coat with appropriate lubricant as described in ‘Recommended Lubricants’ on page 19 of the “LUBRICATION” section.

1.Install bearing (49) and retainer ring (50) in gear carrier (47).

2.Lubricate and install ‘O’ rings (51) on ring gear (53).

3.Align capscrew holes and dowel pins with gear carrier (47) and install ring gear (53). Ensure ‘O’ rings are not damaged during installation.

4.Install planet assembly (54).

5.Install thrust bearing (55) into sun gear (56). Install retainer ring (57) on sun gear and locate in planet assembly (54).

6.Align capscrew and dowel holes and install input housing

(59).Apply a light coating of Loctite® 262 to capscrew (60) threads and install by hand. Equally tighten capscrews in a diametrically opposed pattern to allow for equal compression of housing onto ring gear (53) and gear carrier (47). When ring gear and input housing flanges are flush with gear carrier torque capscrews to 95 ft lbs (128 Nm).

7.Install dowel pins (52) and tap into position until slightly below input housing flange.

8.Install planet assembly (58) onto sun gear (56).

9.Lubricate and install ‘O’ rings (62) on ring gear (63).

10.Install dowel pins (70) in ring gear (63) so they extend an equal distance on both sides of ring gear.

11.Align capscrew holes and dowel pins and install ring gear

(63)on input housing (59). Using a soft hammer or mallet, carefully tap dowel pins and ring gear (63) onto input housing until mating flanges are flush. Ensure ‘O’ rings are not damaged during installation.

12.Place thrust bearing (55) in sun gear (66) and install sun gear into planet assembly (58).

13.Install planet assembly (67) onto sun gear (66).

14.Align capscrew holes and dowel pins and install spacer (71) onto ring gear (63). Using a soft hammer or mallet, carefully tap spacer onto ring gear until mating flanges are flush.

Ensure ‘O’ rings are not damaged during installation.

15.Lubricate and install ‘O’ rings (62) on ring gear (72).

16.Using a soft hammer or mallet, carefully tap ring gear (72) onto spacer (71). Ensure ‘O’ rings are not damaged during installation.
