That can be done and will work IF you have a good solid loud click from the starter when turning the key.

This leads me to believe the solenoid windings have weakened over time and reduced magnetic pull to over ride the tension of the return spring, It's making the gear hit the flywheel but not strong enough to fully engage the flywheel and starter motor contacts.

I have a Cummins starter on my bench right now with this problem, The motor engagement contacts are good but the windings are too weak to fully engage the gear without pulling on it.

Also have a Cummins fuel cut-off solenoid with the same issue, Turn the key on and nothing happens. If you push it half of the movement it will engage and stay.....
