CONNECTING
RODS
The connecting rod uses automotive type bearing inserts on the large end and a pressed in needle
bearing on the piston pin end. If the clearances are not within the tolerances, the bearing shell,
bushing or wrist pin should be replaced.
REPLACE
CONNECTING
RODS
AND
BEARING
SETS
a.
Drain oil from crankcase. Remove heads, compression cylinders, piston rods, and
packing in accordance with the appropriate sections of Chapter 7.
b.
Remove the nuts holding the guide cylinder to the crankcase and lift the complete
assembly including distance piece up and off the guide piston.
c.
Remove the two nuts and separate the connecting rod. The oil dipper does not need
to be removed. Lift the connecting rod and guide piston assembly out of the
crankcase. Remove the capscrew in guide piston and push the wrist pin out to
separate the guide piston from the rod. Match mark the connecting rod upper end
and cap if necessary.
d.
Using a micrometer, inspect the connecting rod bearing, bushing and crankshaft
journal for proper size, out of roundness or taper. Repair or replace as required.
e.
Inspect the wrist pin and needle bearings for wear or damage; replace if necessary.
When pressing needle bearings into the connecting rod, be sure to press against the
stamped end (end with identification markings) of bearings. There are two needle
bearings per rod and the end of each bearing should be flush with the outside of the
connecting rod
f.
Install the guide piston on a new rod in reverse sequence of removal.
g.
Clean the rod and journal with a lint-free cloth and install new bearing shells in each
half of the connecting rod.
h.
Apply a coating of crankcase oil on the bearing shell and crankshaft journal surface.
Position the guide piston and rod on the crankshaft and install the cap, using the
matching numbers on the upper end and cap.
Note
: See photos below for correct oil
dipper location. Install lockwashers and nuts and tighten the nuts to 15 ft-lbs torque.
i.
Reinstall oil dippers on connecting rod caps if previously removed. Both rods require
oil dippers. When installed, each rod should be oriented such that the dipper points
downward towards the oil sump. If dipper does not point downward the rod must be
pulled out and reversed. Torque the oil dipper bolt to 6 ft-lbs.
Warning
Incorrect installation of oil dippers can lead to insufficient
lubrication and catastrophic failure.
