CATERPILLAR-3064-3066-CONROD-BUSH

5I7539 is the connecting rod small-end bush for Caterpillar's 3064 and 3066 engines. On these engines, small-end bush condition is worth checking any time the pistons are out for other reasons — ring replacement, for instance — since access to the bush is essentially free labour at that point compared to a dedicated job later.
