COUNTERBALANCE WEIGHT
NOTE: The wrist pins are tightly pressed into the weight and normally require no maintenance.
Counterbalance Weight Inspection
1. Clean the inside bearing surface and inspect it for wear or damage.
2. Using a telescoping gauge and micrometer, measure the inside diameter of the bearing surface (Figure
13-80, Page 13-38).
3. If the inside diameter is greater than 1.0274 inches (26.097 mm), or the bearing shows signs of wear or
damage, replace the counterbalance weight bearing.
Counterbalance Weight Bearing Replacement
1. Support the weight around the bearing hole and drive the bearing out of the counterbalance weight
with a bearing driver. See following NOTE.
NOTE: Install the new bearing with its oil hole aligned with the oil passage in the counterbalance weight.
2. Clean the parts thoroughly in a high flash-point solvent and wipe dry.
3. Coat new bearing with clean engine oil.
4. Press the new bearing into the counterbalance weight.
Counterbalance Guide Shaft Inspection
1. Clean the shaft surface and inspect it for wear or damage.
2. With an outside micrometer, measure the outside diameter of the guide shaft surface (Figure 13-81,
Page 13-38).
3. If the outside diameter is smaller than 1.0199 inches (25.907 mm), or the shaft shows signs of wear or
damage, replace the guide shaft.
4. Check the O-ring seal to make sure the O-ring is not damaged. Replace if necessary.
