So what you're talking about is NOT typical use of a starter, and NOT relevant to a PMGR starter's reliability in any way. When they're in typical use (on millions of vehicles across the planet, including early Broncos), they typically work as-designed including typically retracting when not powered.
Another positive response-thanks!
(Where is that sarcasm emoji again?)
So typically they retract and this is HOW the starter typically operates IF the engine typically doesn't fire or start but since you haven't seen the dozens of responses & feedback about typical and non-typical situations that weren't posted that I received- then you might have been enlightened about non-typical operation if you were open to it. Where did I ever say they weren't reliable??
I posted up about them not disengaging 100% of the time as a helpful response to others that might be:
1- doing similar work on a test stand some day
2- trying to diagnose similar non-characteristic starter symptoms in an engine that isn't starting or firing
3- trying to maybe share some factual information about the characteristics of the PMGR starters to possibly save others who might be following this thread some confusion and expense.
Steve83- your attitude appears that if something isn't "typically" used for an OE application then we shouldn't share or post about the experience. What a shame that would be.
What you're saying is if your engine doesn't start and you end up sliding underneath to look at possibly an oil leak or to tighten another bolt and you notice the gear drive is still engaged in the flexplate it isn't typical since millions of these starters are never WITNESSED to have this occur... THIS is why I posted up - to possibly try to help someone down the road.
For starters, how many people on this forum don't use stock replacement parts on their rigs and sometimes need help diagnosing symptoms? This POST is about that.
I'd say an overwhelming majority of forum members do AND would be open to any typical or non-typical symptoms of any part/procedure that might be helpful to them or a buddy in the future.
Below is a pic of the pdf file from a Bronco vendor about the "non-typical" issue you don't agree with.
