John c 129 #1 Posted September 19 Does anybody know the torque spec for the alloy spindle housings I'm getting near done on my 42RD rehab project I'm asking about the 4 3/8" bolts on each of the housings Share this post Link to post Share on other sites
peter lena 9,459 #2 Posted September 19 @JOHN C. just curious , did you add another idler pulley to the backside of the idler pulley belt return ? like this , that long , USUPPORTED RUN is a major cause of bearing issues .very easy to set up , and very effective , did that years ago , experimenting with ,REPEDITIVE PROBLEM , added that to my 3 decks , no problems , pete Share this post Link to post Share on other sites

John c 129 #4 Posted September 19 Thank you GW Pete, Not yet, I want to run it first to figure out placement, you'll be proud I stuffed those housings full of green lucas. 1 Share this post Link to post Share on other sites
953 nut 62,190 #5 Posted September 19 Since galvanic corrosion is a problem when using steel bolts with aluminum I would suggest using a good marine grade corrosion inhibitor as a thread lubricant. 2 1 Share this post Link to post Share on other sites
8ntruck 8,156 #6 Posted September 19 Torque spec. - tighten until the bolt breaks or the threads strip, then back off 3/8 of a turn. 2 Share this post Link to post Share on other sites
peter lena 9,459 #7 Posted September 20 @Johnc glad for the lucas green . been absolutely bombproof for me , as far as the added idler goes , you do not need much push back on that belt , that area is just right , for light push back , placed the pully on deck at best spot to be able to gain from its placement , as slight as it is , it removes that shuddering bounce . just drilled a hole used a 3/8 smooth shoulder bolt, no threads on bearing spin area , washer under deck and washer on top of pulley with an elastic lock nut . my regular reference to belt and bearing issues , have eliminated my problems . by the way did you clean out and re grease the mule drive bearings ? same scenario , those 6203 bearings , wide grease shields , really do stand up with lucas green . typically a horse problem , is multi staged , not just one spot / but related / connected . done a lot of that , thanks for the shout , let me know , pete Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,744 #8 Posted September 20 Realistically an inch pound torque wrench should be used so added those values to the original reply. Share this post Link to post Share on other sites

Fastening something to sheet metal ain't rocket science, having basic mechanic skills is all that is needed. Share this post Link to post Share on other sites
