(A) (When removing) 1. Press out the small end bushing with a connecting rod small end bushing replacing tool. (B) (When installing) 1. Clean a new small end bushing and bore, and apply engine oil to them. 2. Press fit a new bushing, taking due care to see that the connecting rod hole matches the… Read More »
1. Measure the piston pin O.D. where it contacts the bushing with an outside micrometer. 2. Measure the small end bushing I.D. with an inside micrometer, and calculate the oil clearance. 3. If the oil clearance exceeds the allowable limit, replace the bushing. If it still exceeds the allowable limit, replace … Read More »
1. Measure the piston pin bore I.D. in both the horizontal and vertical directions with a cylinder gauge. 2. If the measurement exceeds the allowable limit, replace the piston.
(A) (When removing) 1. Press out the used idle gear bushing using an idle gear bushing replacing tool. (B) (When installing) 1. Clean a new idle gear bushing and idle gear bore, and apply engine oil to them. 2. Press in a new bushing using an idle gear bushing replacing tool, until it is flush… Read More »
1. Measure the idle gear shaft O.D. with an outside micrometer. 2. Measure the idle gear bushing I.D. with an inside micrometer, and calculate the oil clearance. 3. If the oil clearance exceeds the allowable limit, replace the bushing. 4. If it still exceeds the allowable limit, replace the idle gear shaft.
1. Measure the camshaft journal O.D. with an outside micrometer. 2. Measure the cylinder block bore I.D. for camshaft with a cylinder gauge, and calculate the oil clearance. 3. If the oil clearance exceeds the allowable limit, replace the camshaft.
1. Measure the height of the cam at its highest point with an outside micrometer. 2. If the measurement is less than the allowable limit, replace the camshaft.
1. Support the camshaft with V blocks on the surface plate at both end journals. 2. Set a dial indicator with its tip on the intermediate journal. 3. Measure the camshaft alignment. 4. If the measurement exceeds the allowable limit, replace the camshaft.
1. Set a dial indicator with its tip on the cam gear. 2. Measure the side clearance by moving the cam gear to the front and rear. 3. If the measurement exceeds the allowable limit, replace the camshaft stopper.
1. Set a dial indicator with its tip on the idle gear. 2. Measure the side clearance by moving the idle gear to the front and rear. 3. If the measurement exceeds the allowable limit, replace the idle gear collar.
