Replacement/installation...mandrel spindel shaft assembly (Part 192872)... SEARS Craftsman lawn tractor Model 917276600...both stars at the end of the shafts are worn. This LOOKS relatively easy...how ever... before diving into this. The mower deck is out from under the tractor. It's the removal of the Toplock Nut that's in question. Can you help? Thank you for your time.
Thank you for your reply. Getting deeper into this...have found other folks on this with the same question. Another question...if the star at the end of that shaft is worn to the point that one can't attach the blade on in order to block the shaft from rotation in order to get that lock nut off...any ideas?
If you have an impact wrench, use it to remove the mandrel nut. If you do not have an impact, use a ratchet and socket (6pt socket is preferred). To hold the mandrel from spinning it works best if a blade is installed so you can prop a piece of 2x4 (or other wood) against the deck and blade to hold it still. If you cannot get a blade to hold, you will need to use a strap wrench to hold the pulley while you remove the nut. If that does not work, you will need to stop by a local auto parts store to see if they rent out an electric impact wrench an use that to remove the nut.Once the nut is out of the way, lift off the pulley, the washer under the pulley and then use a hammer to knock the old shaft out with. Install the new shaft from the bottom side and make sure to replace the upper mandrel bearing. Then install the washer, then the pulley, and then put the nut back.Thank you for using Manage My Life!
Mr Wade B...thank you for your input. We are about half way into this project. I have more inputs coming. This basically started out as a back yard mechanic project...oops...looks like we have to replace the mower blades... and then the snow ball started getting bigger... This is a project that is not very difficult overall...just time consuming. It's going to take about a week to complete this...waiting for parts etc. Anyway I'll be putting inputs in as we go along on this. Again thank you. P.S. Yes...we got "That Nut" off. A breaker bar (of sorts) works wonders...
