Power End Assembly
Plunger Assembly
Note: The numbers in parentheses are the Reference
Numbers shown in the Parts Section of the manual.
a.
See Power End Parts Illustration.
Start with crankcase (2)
clean and ready to assemble.
b. Assemble plunger (53), spherical washer (27), slider (4),
belleville spring (28), with shoulder screw (29). Use Loctite 242
and torque to 50 ft-lbs (68 N-m).
Note: One concave side of spherical washer assy (27) mates
with plunger (53) and the other convex side of spherical
washer assy mates with slider (4).
c. Assemble three sets.
Connecting Rod Assembly
Note: Each of three Connecting rod assemblies (3*)
consists of: connecting rod, connecting rod end cap,
sleeve, and two bolts.
a. Attach assembled plunger and slider to connecting rod (3*)
using wrist pin (5). Align marks on wrist pin with marks on
slider (4). Lock wrist pin in place with setscrew (23). Use
Loctite 271 and torque to 60 in-lbs (7 N-m).
Note: Make sure to note 'top-up' orientation of numbers
on connecting rod and end cap when taking apart. These
are matched parts and must not be mixed with parts from
other connecting rod assemblies.
b. Remove two bolts (3*) and connecting rod end cap (3*)
from connecting rod assembly. Note orientation numbers
on connecting rod and end cap.
c. Set aside bolts and end cap for later installation. Do not mix
with parts from other connecting rod assemblies.
d. Install one half of split shell bearing (8) on connecting rod.
Remaining one half of split shell bearing will be installed later.
e. Insert connecting rod/plunger assembly into crankcase and
push all the way forward. Ensure numbers are "top-up."
f. Assemble and install three sets.
Seal and Bearing Assembly
a. Press two crankshaft seals (11) into seal cover (9). Install
O-ring (19) onto seal cover.
b. Install roller bearing (7) into bearing cover (6). Install O-ring
(18) onto bearing cover.
c. Bolt seal and bearing assemblies together using six cap
screws (15).
d. Assemble two sets.
W
ARNING: Crankcase (2) and assembled parts weigh
over 400 pounds (181 kg) and are a two man lift. Use
care in handling to prevent personal injury or damage
to equipment.
Crankshaft Installation
a. Install one seal and bearing assembly to either side of
crankcase (2) using six screws (15). Crankshaft (1) will be
installed on opposite side.
b. Place remaining seal and bearing assembly on following end
of crankshaft.
Note: No shimming of crankshaft is necessary. End play
of crankshaft should be between 0.010 in. minimum to
0.200 in. maximum when installed.
c. Insert crankshaft with seal and bearing assembly into
crankcase and insert into installed seal and bearing
assembly on opposite end of crankcase. Align flange of seal
and bearing assembly with flange on crankcase.
d. Bolt flange of seal and bearing assembly to crankcase with
six cap screws (15). Torque to 12 ft-lbs (16 N-m).
Connecting Rod Installation
Note: Each of three Connecting rod assemblies (3*)
consists of: connecting rod, connecting rod end cap,
sleeve, and two bolts.
a. Attach connecting rod assembly to crankshaft (1) by reaching
into rear of crankcase around crankshaft and pulling
connecting rod assembly until it reaches its journal on the
crankshaft.
Note: Make sure to note 'top-up' orientation of numbers
on connecting rod and end cap when installing. These are
matched parts and must not be taken from other connecting
rod assemblies.
b. Retrieve connecting rod assembly bolts, end cap, and
remaining split shell bearing (8) set aside in previous steps.
c. Reinstall connecting rod end cap with remaining split shell
bearing using connecting rod assembly bolts. Make sure
numbers on connecting rod and end cap are 'top-up' in the
assembly and match. Torque two bolts to 100 ft-lbs (136 N-m).
d. Repeat installation for three sets.
Crankcase Assembly
Note: for torque values refer to the table following the Parts
List Section.
a. Install back cover (12) and back cover baffle (13) using 12
cap screws (16).
b. Install crankshaft cover (10) on crankshaft end not used
with six cap screws used to attach seal and bearing
assembly.
c. If removed, reinstall four studs (20), with four set screws (21),
four studs (19), and two eyebolts (14).
d. Install plug (40), cap with o-ring (25), dipstick (32), and
crankshaft key (31) and add lubricating fluid.
