Link Rod Bushing Replacement
1. Support the link rod around the entire large end, and using a 1.97 inches (50 mm) bearing driver (1),
drive the bearing (2) out of the rod (3) as shown (Figure 13-80, Page 13-37).
2. Clean the parts thoroughly in a high flash-point solvent and dry them.
3. Coat the new bearing with new engine oil.
4. Using a 1.97 inches (50 mm) bearing driver, press the new bearing into the link rod with its seam (6)
toward the side of the link rod with the hollow (5) and at right angles to the rod center, to a depth of
0.039 inch (0.991 mm) from the surface (Figure 13-81, Page 13-37).
COUNTERBALANCE WEIGHT
Counterbalance Weight Inspection
1. Clean the inside of the bore surface and inspect it for wear or damage.
2. Using a telescoping gauge and micrometer, measure the inside diameter of the bearing bore. If the
inside diameter is greater than 1.0283 inches (26.119 mm), or the bore show signs of wear or damage,
replace counterbalance weight (Figure 13-82, Page 13-38).
