SERVICE PROCEDURE
HEAD SUBASSEMBLY
Disassembly Instructions:
•Remove the bleed screw (38) and drain the fluid.
•Loosen set screw (20) and remove the pulling head.
•Remove the screws (26) and the sides (17) and push out the pins (23 and 41).
This will allow frames (19 and 40) to fall free and rocker arm (24) may then be lifted out.
•Remove the screws (12) from top and bottom of the cylinder the remove the springs, spacers, and limit bars (13, 14, 15, 16 & 39)
•Unscrew the cap (9) and pull on the cam (11); remove the set screw (10) first should removing the cam from the piston (4) be
necessary
Assembly Instructions:
•Build the cylinder assembly first; assemble items (1) through (11) making sure the set screw (10) is tight against piston rod (4).
•Place frames (19 and 40) one on top of the other; they should fit together with no warping.
•Install rollers (18) in upper frame (19), using pin (23).
•Install bearings (22) in rocker arm (24), using pin (21) and install rollers (18) in lower frame (40), using pins (30).
•Place sleeve (25) in the large hole of the lower frame (40).
•Install the rocker arm (24) in the lower frame (40), using pin (23).
•Thread the adjustment-screw (28) in through the lower frame (40) and secure it with jam nut (29).
•Slide the lower frame (40) over cylinder assembly (36) making sure that cam (11) is in the correct position with the flat section at the
bottom as shown in sketch. Insert pin (41) through frame and through bottom hole in cylinder (36).
•Slide the upper frame (19) over the cylinder assembly (36) and hold in place with pin (41).
•Place sides (17) over the frames (19 and 40) and secure with screws (26), using washers (27) over the front two screws, between the
sides and the frames, for clearance.
•Attach leaf springs (39 and 16), spacer (14), and limit bar (13) starting with lower frame, using the screws (12).
Note: Leaf spring (39) should be all the way forward and aligned with large hole in lower frame. Repeat this operation with upper
frame. Make sure that all hoses and fittings are connected properly as shown in the exploded view.
POWER HANDLE SUBASSEMBLY
Disassembly Instructions:
•Remove the Manifold (49) and set it aside
•Drain all the fluid, then turn up-side down and remove the screws holding the bottom cover (87);
•Push the power piston all the way down, remove the cotter pin (82) and unthread the locknut (81) and then remove the air piston (80)
by using wrench 530A86 and a 9/16” socket wrench; hold the top of the piston with tool 530A86 to prevent it from turning. When
completely unthreaded, insert the thread end of too 530A88 into the bottom of air piston (80) and using it as a handle, pull the piston
out
•Remove packing plug (77) with the help of wrench 530A83 and a 1-1/16” socket wrench.
•Tap the power cylinder (70) from the top (use tool 530A88); when loosened, it will fall through the bottom of the handle.
•Remove all the seals and inspect all components for wear. Replace all seals and worn components
Assembly Instructions:
•The re-assembly sequence is the opposite of disassembly; to prevent damage to piston threads; suggested tightening torque for the
locknut (37) between 50 and 59 in-lb (5.65 and 6.67 N-m).
•After service, the riveter must be primed and bled (page 12)
AIR VALVE SUBASSEMBLY
Disassembly Instructions:
•Remove retaining ring (69) and muffler (68).
•Pull out the valve plug (67) and the Valve Spool (65) with the help of extractor P1178;
•Dislodge and pull the spring (63) out using needle-nose pliers
•In the unlikely event that you want to pull the Valve Sleeve (62), use the tool 837B530 (internal expansion collet).
Assemble Instructions:
•Replace all O-Rings and apply an O-ring lubricant (Parker® silicone lube or equivalent).
•To re-assemble, reverse the procedure given above; snap the Spring (63) into its groove with the help of tool 836B530
