Time once again to pick the experienced minds.The newly installed, rebuilt starter on my 1974 TR6 after only one months usage is missing and grinding a lot. So I pulled it, inspected and bench tested it, and checked & made misc measurements of the ring gear thru the starter mount hole. The pinion gear is beat up but thankfully the ring gear looks none the worse. The bench test showed the starter working good but I noticed that the pinion gear hits the stop ring on initial firing but immediately backs off from the stop ring .163". So I wired the starter to only energize the solenoid and found it the same. Is this how it's supposed to work or should it remain pressed against the stop ring/collar? I carefully measured the ring gear position to the engine/trans mount plate and did likewise with the starter and the position of the pinion gear. Put the numbers together and even on full throw the pinion & ring gears are only engaging 3/16+". Can this possibly be correct? I further measured that the ring gear was postioned on the flywheel 3/8" from the engine face of the flywheel and it's firmly tack welded there. Is this positioning correct or did a po have some bad work done? I've only owned the car two years and in that time the starter would only occasionally miss. It's like 10x that now with the rebuild. What be the thoughts and advice?
Thanks, Steve
