scwheelhorse 56 #1 Posted October 1, 2019 Can someone please provide me with deck bearing numbers for my 42 in deck on my c120? Share this post Link to post Share on other sites
peter lena 8,583 #2 Posted October 1, 2019 probably 6203 rs , with 3/4" id measurement , i used timken oil seals # 473380 on the upper seal end, also used lucas red and tacky grease to lube those spindles , high 550 temp drop point ensures ,positive lubrication, don,t forget to change the idler bearing , usually a noisy bearing . you can cross chart what i used if you want to w/h parts , or go on amazon or ebay . any other questions just ask , the site, pete Share this post Link to post Share on other sites
scwheelhorse 56 #3 Posted October 1, 2019 I read somewhere bearings depend on spindles used. I can post a spindle pic if that helps. Share this post Link to post Share on other sites
daveoman1966 3,745 #4 Posted October 2, 2019 If your spindle PULLEY uses a Woodruff key, the bearing would be with 3/4" center bore. 106085 (double seal) or 106084 (one seal) (6203) If no keyway is used, the spindle shaft is then 5/8" dia...and the bearing ID would also be 5/8".

scwheelhorse 56 #6 Posted October 2, 2019 Why is there grease fittings on the mower deck when it uses sealed bearings? Serves no useful purpose. Share this post Link to post Share on other sites
peter lena 8,583 #7 Posted October 3, 2019 on the lower side of the bearings ( inside spindle ) you remove the seal so you can refresh the grease in the spindle chamber . i also put in grease between upper and lower bearings , so its off to a good start , ensuring reserve grease to work properly. if you don,t remove the lower inside seal , it will never get a fresh grease refill, pete Share this post Link to post Share on other sites
Lee1977 6,647 #8 Posted October 3, 2019 The C-120 came with Double D spindles . They could have been upgraded to the later model spindles. I have never replaced any DD spindles bearings. The other two are 3/4" keyed spindles they use 6203-12 RR bearings ( 40 mm OD 3/4" ID and 12 mm thick. The metric spindles use 6203 (40 mm OD 17 mm ID and 12mm thick. The metric spindle will have a 5/8" nut on top. Share this post Link to post Share on other sites
