I have a Briggs & Stratton 14 1/2 Hp engine.
The starter relay was open-circuit. I replaced that and the
starter motor runs, but the pinion doesn't engage the starter
Do I have to get a new starter?
Is there some inertia device that extends the pinion gear - what causes
the pinion gear to engage the starter gear?
How difficult is it to repair, or should I just get another starter motor?
Might not be difficult at all. Might be just dry and dirty. I would try to
spray WD40 on it right on the machine. If that doesn't work take the
starter off the machine - don't take it apart - just try to blow it out and
see it it is just stuck - you should be able to pull the pinion out by
hand - lube and put it back on.
I wished I had a picture. I couldn't find any on the web.
I took the cover off so that the pinion is visible.
It seems that there are two (maybe) components to its vertical movement.
The pinion itself moves upward against a fairly flimsy wire spring. Then,
it seems that the entire shaft can move upward? However, that seems to
require significant force. Compressing the flimsy spring almost gets
it to the starter gear.
History. The starter did nothing until I replaced the solenoid (relay).
After I replaced the replay, the starter runs, but the pinion does not
engage. Doesn't seem possible to have switched the polarity. Which
way is the motor supposed to turn?
Take the starter off the engine, use WD40 on the spiral shaft to clean it.
Excersize the drive while you do this. Depending on how well sealed the
starter is I would use nothing if dirt can get in, if it's well sealed a
little lithium grease.
