Replaced starter on a 2003 660 raptor and still having the problem of it not being able to ingage when trying to start it,it sometimes will ingage but most of the time it will it grinnds

sounds like the starter clutch is bad. the rollers get worn or the sprag gear gets worn so it will not grab and start the motor. check that out. you will have to take the engine side cover off to see it.

Check your blade ingage switch. Sometimes they stick. You can jump start it by jumping across the solenoid switch beside the engine. I sometimes have to engage and disengage my blade switch and it starts. Hope this helps.

there is a gear on the starter you need to remove starter to see if its worn out also it sounds like its not ingaging.when you have stater off check for wear on both gears if there is no teeth worn on drive gear.replace starter cause of problem is the bendix in the starter.

needs shimmed or the bendix is bad in the starter and not allowing to release. most likely just needs shimmed if it's a new starter, however you can get a bad starter (new or rebuilt)

Replace the starter switch.

The start circuit from the ignition switch to neutral safety switch to the solenoid on the starter might be bad. Look for power there at solenoid or at neutral safety switch when it doesn't want to crank over.

Your starter solenoid is bad. It comes with a new starter. Replace the starter and your problem should go away.

The way the solenoid it designed, the starter gear MUST engage the ring gear in order for the starter to start turning. The plunger inside the solenoid has to go all the way forward in order to make electrical contact to start the motor.

Now, that doesn't mean that the starter gear WILL turn the engine. It sounds like you've got a bad "over running" clutch. When these units go bad, you can hear the starter motor running but the engine is not turning over.

Now, here's the rub on that. If you have the abilitiy to remove the starter, disassemble it, and replace it, you can save yourself some money. If not, you're better off simply replacing the starter.

The part cost about $100 but the time it takes to put it in will quickly eat up any savings you might have by repairing the starter rather than replacing it. Labor rates are high these days.

Good Luck

battery has a low charge or the starting gear on the starter is bad. just remove cover and see if the starter ingages and cranks the fly wheel. look at the gear itself to make sure the teeth are good ,if not replace the plastic gear. takes 5 min.

shim the starter it sounds like it is staying engaged to the flywheel try shiming the starter
