Q:

I have Ceaftsman model 917.370580 lawnmower. How do I remove Pinion #188331 from left rear wheel drive.Replacing dust cover and pinion assembly. 917370580 Craftsman Lawn mower

A:

Thanks for the inquiry and for being a valued member.

Once the E-ring is removed, the pinion should pull off. If that is not the case, it could be rusted to the shaft. Try some penetrating oil and light tap the pinion to allow the oil to penetrate. Let it soak for a few hours and tap the gear again to break it free. It should pull off. If it's still being stubborn, you could try using a gear puller, but it will usually come loose with oil and light tapping. 

I hope this helps and thanks for using SearsPartsDirect.com. We appreciate your business.

A:

Remove the cover for the transmission pulley on the back left side of the mower deck. There should be a little cube shaped cover under there that contains the battery. If you do not see the battery/cover under the transmission cover then the battery will be located under the mower. Tip the mower on its side and look towards the back left side for the cube shaped cover containing the battery unit.

Thank you for using Manage My Life!
