NOTICE
This following installation can be accomplished more easily by
aligning the compressed Blades with the webs at the narrowest
portion of the opening. Keeping the Blades on the web allows
them to slide the length of the Liner without interference.
9. Using fi nger pressure, compress the Springs with the Blades
until the outer edges of the Blades are fl ush with the drive shaft
surface. Capture the Blades in this position by installing the Liner
Assembly, guide spring end trailing, over the Drive Shaft and
against the Rear Liner Cover. Make certain the Liner Pins (43) in
the Liner enter the holes in the Cover.
10. Insert the hub end of the Rear Liner Cover into the Disassembly
Arbor from the Tool Kit and stand it on a workbench with the
Drive Shaft upward.
11. Install the Seal Back-Up Ring (53) followed by the Drive Shaft
O-ring (52) in the central opening in the face of the Front liner
Cover.
12. Install the Front Liner Cover Assembly over the Drive Shaft and
against the Liner.
For Model 500A, make certain the Oil Stop Cap Assembly aligns
with the Spring Guide assembly.
For Model 700A, make certain the Torque Adjustment Screw (57)
aligns with the proper spring guide opening that was marked
during assembly.
13. For Model 500A, install the Liner Cover O-ring (41) in the groove
that was formed where the Rear Liner Cover contacts the Liner
and install the Liner O-ring (37) in the groove formed where the
Front Liner Cover contacts the Liner. Lubricate the Seals with
O-ring lubricant. (Refer to Dwg. TPD1312).
Liner Seals
(Dwg. TPD1312)
14. For Model 500A, apply some grease to the Liner Cover Seal (68)
and install it in the grooves inside the Liner Housing (32) near the
end with the external wrench fl ats.
For Model 700A, apply some grease to the two Liner Cover Seals
(68) and install them in the grooves inside the Liner Housing (31)
near the end with the external wrench fl ats.
15. For Model 500A, orient the Liner Housing so the Liner Cover Pin
(55) will enter the hole in the Housing and install the Housing
over the Liner.
For Model 700A, place the Liner Housing Seal end trailing, over
the assembled Liner. Make certain the notch in the trailing end
face of the Housing aligns with the Oil Plug (59) in the Front Liner
Cover. Use the Pressing Sleeve from the Tool Kit to oppress the
Housing over the Seals during installation.
16. Grasp the fl ats of the Liner Housing in the vise jaws with the
output spindle downward. Remove the Rear Liner Cover and fi ll
the recess in the Cover with grease. Reinstall the Cover and push
it downward below the threads at the rear of the Housing.
17. Using Spanner Plug furnished with the Tool Kit and a torque
wrench, install the Housing Cap, (castellated end leading for
Model 700A). Tighten the Cap between 101 and 116 ft-lb (137
and 157 Nm) torque.
18. Make certain the Drive Shaft rotates freely and then fi ll the
mechanism with fl uid as instructed in the section, CHANGING
THE MEVHANISM FLUID.
Assembly of the Angle Head
1. If the Spindle Shaft Busing was removed, press a new Bushing
into the Angle Housing (69), large end trailing, until it seats.
2. Lubricate and install the two pinion Bearings (75) on the shaft of
the Bevel Pinion (77) and insert the assembly, gear end leading,
into the motor end of the Angle Housing.
3. Install the Pinion Bearing Cap (73) and tighten it snug.
4. Insert the Spindle Shaft (79) into the gear end of the Spindle (81).
5. Chalk the gear teeth of the Spindle and carefully insert the
assembly into the Angle Housing. Make certain the Shaft enters
the Bushing. Install the Spindle Cap (85) and lightly tighten it.
6. Using a wrench on the square drive, rotate the Spindle to
suffi
ciently mark the chalked gear teeth. Carefully remove the
Spindle Cap and examine the gear teeth.
7. If the gearing runs smoothly and gear tooth engagement is
good, reinstall the Cap and tighten it and the Pinion Bearing Cap
securely.
If the gearing does not run smoothly or gear tooth engagement
is poor, proceed as follows:
Determine which way the Spindle or Pinion must move to
improve engagement.
Insert the correct thickness Pinion Bearing Shim (76), Spindle
Upper Shim (80) or Spindle Lower Shim (84) separately or in
combination to achieve the desired engagement.
Chalk the gear teeth and test the tooth engagement again.
When satisfi ed that the proper bevel gear engagement has
been achieved, tighten the Spindle Cap and Pinion Bearing
Cap securely.
8. Remove the Grease Plug (71) and fi ll the cavity with gear grease.
9. Install the Bearing Cap Retaining Screw (74) and Spindle Cap
Retaining Screw (86) and tighten them securely.
10. Install the assembled Impulse Unit Drive Assembly on the rotor
shaft in the Motor Housing (1).
11. Install the Angle Housing Space (72), small opening leading, into
the Drive Shaft (48) against the impulse mechanism.
12. Place a new Gasket (78) on the Angle Housing and install the
assembled Angle Housing over the Drive Shaft against the
Housing. Install the four Angle Housing Mounting Screws (89)
and Lock Washers (90). Tighten each Screw between 45 and 50
in-lb (5.1 and 5.6 Nm) torque.
