Question 1998 FLH
WHEN I hit the starter button the starter spins. sometimes it cranks the engine sometimes it does'nt.
the starter spins as long as you hold the button.
but it sounds like the pinion is not staying engaged with the ring gear.I replaced the starter clutch,but it didn't seem to make much difference.
Can the jack shaft and pinion be tested?The pinion gear did not look damaged or worn.
Answer Sounds like the solenoid,Gale. Solenoid is piggybacked to the starter and is just a big electromagnet. When the solenoid doesn't pull the plunger all the way in toward the primary, the drive gear isn't getting into the clutch ring gear to turn over the motor. The starter motor itself will spin all day long if the solenoid isn't throwing out the drive gear. You can usually see if the splines on the jackshaft are bad, but it sounds like it's the solenoid. Also, the jackshaft extension (steel tube with internal splines and a circlip inside) is meant to go on in only one direction. Did you put it on facing the right way? The internal circlip is closer to one end than the other. The end that it is closer to goes towards the starter or away from the inner primary.
