Model #917377641 Craftsman walk behind lawnmower, gas

Question and Answers

Q:

How do I install replacement part number 405995 on my Craftsman lawn mower model number 917377641?

A:

The cable drive part number 405995 should work ok. You can shape the cable to take up the slack and just be sure both ends mount in the spot the old cable mounted in. The skirt part number 408442 has been used for several years and should work ok too. I don't find any history of either part not substituting ok.

Q:

I have a walk behind gas mower, model 917377641. I need the pulley which the pull string winds around. It sits on top of the mower. Can you get me the part number??

A:

You can buy a complete rewind starter assembly that comes with the starter rope already wrapped around the pulley and ready to use. You remove the original starter assembly and install the replacement in its place.

The spark plug wire is soldered into the ignition module and you have to buy the ignition module to get the spark plug wire.

The part number for the starter assembly for the lawnmower is 590739 and the cost is around $45.00. The part number for the ignition module is 440505, and the cost is around $40.00.

Q:

How do you remove the engine pulley for model 917.377641?

A:

The engine pulley is rusted to the engine shaft. Spray the inside of the pulley with rust buster and tap on the pulley to cause the rust buster to penetrate.

Remove the washer from the blade bolt and screw the bolt into the engine shaft 1/2-3/4 inch. Hook a gear puller up to the engine pulley and let the bolt in the puller push against the head of the blade bolt. The puller will remove the pulley.
