| - | ===== Cam Gear Oiler ('85 only) ===== | ||
| - | |||
| - | Starting with crankcase number 785 303 002, manufactured after October 29, 1984, a cam gear oiler was installed in the gearcase ceiling. ((HD TSB #M-899 dated November 30, 1984)) \\ | ||
| - | The cam gear oiler directs oil from the top end oil passage to the gear mesh between first and second gears and third and fourth gears. \\ | ||
| - | Direct lubrication of the gear teeth allows tighter gear fitment. Gear backlash and noise are reduced. \\ | ||
| - | |||
| - | * The oiler tube has restricted orifices to spray the gears and still retain main oil feed pressure from whence the oil came (top oil feed galley). | ||
| - | * There is an O-ring on the oiler tube nipple that is pressed into the ceiling of the gearcase. | ||
| - | * If the O-ring fails to seal the oiler tube, feed oil pressure to the top end could be low. \\ You probably wouldn't see a leak as it would be inside the gearcase. | ||
