Cam Bushings

  • The cam bushings get their oil from the fling off of the cam gears and drain back from the top end down the pushrod tubes that puddles in at depressions in the castings where the cam bushing slots are aligned. So basically they are drip fed. Also the cam bushings on the case side are open to the crank behind them, and probably get splash there too. 5)
