The subject of Mini starters or so called high torque starters, has been discussed here on several occassions. Some users are quiet happy with the operation of them, especially as they are lighter & easier to install. However, I've read of at least one case, where use of one resulted in the ring gear being pushed off the flywheel. Apparently this is because the original bendix equipped starters on Y-Blocks, engaged from the rear, and the Ring Gear stops on the flywheel are on the front.. It appears that most or possibly all mini starters appear to have some sort of  engagement from the front.. In any case, looking at the starter sold by Automotive Electrical Services (for instance) can some one explain to me how this setup works? Is it engaged in the ring gear all the time & just free wheels when not engaged or does it actually project rearward to engage?. Further, how is it that a much smaller starter can be referred to as being high torque?  Would  "a  gear reduction starter" be  a more appropriate description?  Thanks..
