New high torq starter - not extending and engaging, Fixable or replace Options

[echocanyons]

I had a new high torq starter installed recently.
It seemed to be working fine until today.

It spins fine, it just doesn’t seem like it extends a engages with the flywheel.

It was installed by a team who knows these cars well and had worked
until today. I don’t think the install was an issue.

Is there a way to fix this?

For what it’s worth WOSP and other in this line of business buy a standard DENSO starter motor and then they machine the end plate for the specific application which is seemingly endless. Based on the size of the application list, I’d be willing to bet there is no serious validation testing on each application to ensure robust performance and fitness for use.

If the motor is spinning, you can almost bet the end plate isn’t properly machined or properly aligned on the DENSO motor such that the pinion gear is not able to throw forward and engage the ring properly.

You may want to remove the starter and then fiddle with it on the bench to see what is binding up the forward throw of the pinion gear.
