NOTICE

• When connecting fittings ensure that air lines are connected
as shown in Dwg. MHP1331. Various fitting thread types are
used (i.e., metric, British, JIC and NPT). Ensure the correct
mated threads are joined; do not force fittings.

Connect fittings and route air lines as shown in Dwg.
MHP1331.

10. Insert capscrews (526) through bracket (527) and slide

spacers (532) onto capscrews. Place this entire assembly
onto the bolt holes on the air inlet side of the control valve
assembly and loosely tighten capscrews (526).

11. Connect union (536) and tighten.
12. Tighten capcrews (526).
13. Connect fittings (513) to manifold connectors (534).
14. Insert nipple (524) into muffler. Insert this assembly into

elbow (523) and tighten.

15. Insert elbow (523) into exhaust port and tighten. Locate

muffler in position noted during disassembly.

9.

Follow steps 1 through 6 of ‘Installation of Remote Control
Valve and Inlet Manifold’ section.

Reduction Gear Assembly

Refer to Dwg. MHP1248.
1.

Press caged needle bearings (57) into reducer housing (59).
With oil seal (58) lip facing towards reducer housing,
install oil seal in reducer housing.

2.

Install thrust washer (44) in groove in output planet carrier
(35).

3.

Determine planet gear (43) to carrier (35) end clearance for
each gear:

NOTICE

• Shim output carrier (35) planet gears for 0.005 to 0.032
inch (0.1 to 0.8 mm) end clearance between gear (43) and
carrier.

a.

If not noted during disassembly, determine planet gear
(43) end clearance. Place planet gear in carrier (35)
and insert pin (36) to hold in place. Slide gear against
one side of carrier wall. Measure the gap between
opposite side of carrier interior face and gear. Repeat
for each gear.

b.

Measure the width of two washers (38), (39) and (40).
Combine the amounts of the washers and subtract from
the amount of the gap determined in step a. Add or
remove washers as necessary to establish a 0.005 to
0.032 inch (0.1 to 0.8 mm) end clearance. Repeat for
each gear.

4.

Assemble and install planet gear assembly in the output
carrier (35):
a.

Cut two pieces of cardboard into 3 inch (76 mm)
squares. Place planet gear (43) on one of these pieces
and place pin (36) into hole in center of gear. Insert
eighteen roller bearings (41) between pin and gear.
Take care to ensure initial pins inserted do not tip
over.

b.

Insert spacer (42) followed by the second set of 18
roller bearings.

c.

Place half of the washers required to establish end
clearance (refer to Step 3b.) over pin and against gear
face. Grasp assembly, including cardboard, and flip
over onto second piece of cardboard. As gear slides
down pin onto bottom cardboard, allow pin to push
top piece of cardboard off.

d.

Place other half of the washers required to establish
end clearance (refer to Step 3b.) over pin and against
gear face. Grasp assembly carefully and move to
carrier.

e.

Slide assembled gear partially into position in carrier,
up to pin. Slowly remove pin taking care not to let
bearings tip over or fall. Carefully slide gear assembly
into carrier, aligning hole in gear with hole in carrier.

e.

Place output planet pin (36) into one end of output
carrier (35). Ensure end of pin, with hole, is inserted
such that it will line up with hole in carrier for roll pin
(37) installation.

f.

Slide pin (36) until hole in pin and hole in carrier are
aligned. Verify end clearance tolerance is 0.005 to
0.032 inch (0.1 to 0.8 mm). If required, add or remove
washers to adjust clearance. Secure pin to carrier using
roll pin (37). Carefully tap roll pin into place taking
care not to ‘mushroom’ the head. Tap until level with
top of carrier.

g.

Repeat procedure for remaining gears.
