submcpo 1 #1 Posted October 21, 2022 Would like to find the recommended torque for the spindle mounting bolts on a 05-42MS05 mower deck. I don't want to risk cracking the housing. Thanks Dave Share this post Link to post Share on other sites
953 nut 55,120 #2 Posted October 21, 2022 Thank you for asking in advance. It is important to chase the threads in your spindle with a tap before inserting the bolts so you get an accurate reading. Also, it is best to replace the steel bolts with Stainless Steel fasteners. If you are using grade 5 steel bolts, 5/16" the proper torque is 15 foot pounds, if they are 3/8" it will be 25 foot pounds. With Stainless Steel the torques would be 11 and 20 respectively. What type of fastener is best for aluminum? While many people worry that stainless steel fasteners, such as screws, bolts, nuts, or host of other options, won't work with aluminum due to the risk of galvanic corrosion between the two very different metals, the truth is that stainless steel is the metal of choice for fasteners to secure your aluminum materials 1 1 Share this post Link to post Share on other sites
Pullstart 62,812 #3 Posted October 21, 2022 I always say crank it until it snaps, then back it off a 1/4 turn Truth be told, most fasteners I “just have a feel for.” 1 Share this post Link to post Share on other sites

submcpo 1 #5 Posted October 23, 2022 Thanks everyone for the help. I did manage to reassemble the mower deck today without any damage to it or myself (I think). First time I've had to work on the spindles in the 35 years I've owned the machine. Share this post Link to post Share on other sites
