DISASSEMBLY AND ASSEMBLY
Hand Pump (or electric)
a) remove pistons
Remove the rings from the piston with tool (A).
Remove the bearings from the connecting rod
and connecting rod cap.
Remove retaining rings (3), pin (1) and con-
necting rod (2) from the piston.
Heat the connecting rod to a temperature of
350 to 500° F (176 to 260°C). Put 6V3029
Spacer (11) in the base plate. Put the connect-
ing rod on the base plate of tooling (B).
Put the connecting rod piston pin bearing end in
the center of the port assembly of tooling (B).
Install pin (6) in the center of the bore for the
connecting rod bearings.
Install 6V2049 Adapter (9). Put the hole in the
adapter in alignment with the hole in the base
plate of tooling (B).
Install clamp bar (10) and clamp pin (7).
Install new piston pin bearing (5) on adapter
NOTE: The old bearing is pushed out by tooling (B)
as the new bearing is installed.
9. Put 5P8645 Adapter (8) in position as shown
with the taper side down. The piston pin bear-
ing joint must be in alignment with the hole in
adapter (9) and the base plate of tooling (B).
10. Put pusher (4) on adapter (8).
11. Use tooling (B) to push the new piston pin
bearing into the connecting rod until adapter
(8) of tooling (B) makes full contact with the
connecting rod surface.
12. Remove the connecting rod and the old piston
bearing from tooling (B).
13. Check the piston pin bearing bore diameter
after the bearing is installed. The correct di-
mension is 1.7012. ± .0003 in. (43.210 ± 0.008
