Assembly of Impulse Mechanism
1.
Install O-Ring (57) and then the Back-Up Ring (58) on Adjust
Bolt (56). Use the Assembly Arbor - Jig J to slide the Adjust Bolt in
the hole of the Assembly Arbor - Jig I until the Back-Up Ring sticks
out of the bottom. Then use Jig I to press the Adjust Bolt into the
Liner Lower Plate (54). Be careful not to cut the O-ring during

2. Install O-Ring (61) and the Back-Up Ring (62) to the Main Shaft (51).
Pay attention to the direction of the Back-Up Ring on Q110P4. The
chamfered edge should be towards the front of the shaft.
3. Install the Relief Valve (49) in the Liner (47), aligning the long hole
in the relief valve with the hole in the outside of the liner. Ensure
the Relief Valve slides in smoothly and then install the Pin (50) in
the Liner.
4. Place a Blade (52) into one of the slots of the Main Shaft (51) with
the blade assembly pins inward.
5. From the opposite side of the Shaft, encircle each Pin with a Blade
Spring (53).
6. Install the Assembly Pins of the remaining Blade in the open ends
of the Springs.

7. Compress the Springs with the Blades until both Blades are flush
with the Drive Shaft. Install the Liner over the assembly, lining up
the two Pins (48) with the holes in the Liner Lower Plate. The side
with the relief valve goes towards the output end of the main
shaft. The hole for the Relief Valve should line up with the Adjust
Bolt on the Liner Lower Plate. Make certain the ends of the Blades
are flush with the ends of the Liner. (Refer to Dwg. 16595977).

9. Ensure the Adjust Bolt is lined up with the Relief Valve and
using a 1.5 mm hex wrench, supplied with tool, turn the adjust
bolt counter clockwise until it stops. Then turn it back clockwise
90 degrees.
10. Lubricate the Front Liner O-Ring (43) and install it in the forward
bore of the Liner Case (42).
11. Install the Dowel Pin (55) into the Liner Lower Plate.
12. Assemble the Liner Case over the mechanism assembly and line it
up with the Dowel Pin in the Liner Lower Plate.
13. Insert mechanism into Holder - Jig H and then clamp the flats on
the Holder in a vise with the output spindle downward. Remove
the Liner Upper Plate and put grease in the central opening of
the Cover. (Refer to Dwg. TPD1289).
