Stepney 2,354 #1 Posted January 1, 2013 Hello again, and happy new year! Well, today the mule drive let go on my 1974 B-80. It has the cast front idlers, and I did get the bearings out. They don't appear to be original as they are made in Japan, by POLORON, and are number 967401. I can't find ANYTHING to do with the name or part number! I have read here about replacing these, but I've never found the part numbers. Does anyone know them? Thanks in advance. Spenser. Share this post Link to post Share on other sites

Anglo Traction 761 #5 Posted January 2, 2013 As TT's dims & prt nbr says. You can also search for General GB-22612-88 , which is a part number I have on the original old bearings I removed from my 74 Mule drive. There were 2 for sale on Bay of E a while back. but for me the shipping costs were prohibitive. Regards Share this post Link to post Share on other sites
Butch 194 #6 Posted January 3, 2013 The 1630-2RS are only a couple bucks each on Ebay. Share this post Link to post Share on other sites
Stepney 2,354 #7 Posted January 7, 2013 Odd, I measured my bearings and got .575 ID, .750 ID, and .675 on the side. Maybe I messed something up? Spenser. Share this post Link to post Share on other sites
ineedanother 1,729 #8 Posted October 6 Bringing this up as I'm putting a mule drive together...what I knocked out were POLORON 967401 which are NLA. NAPA and others typically cross reference those to a National bearing 203 or 2033 something but those aren't 3/4". SKF 6203-C3 is what you need. Pull the seals and repack them though The pic below is what they came to me with for grease. Unsatisfactory if you ask me and lest I awaken @peter lena 1 Share this post Link to post Share on other sites
peter lena 9,465 #9 Posted October 6 @ineedanother every one of my 6203 bearings , have the lucas xtra hd , green chassis grease , for bombproof smooth / quiet operation , all my mule drives , are driven by , pto inner needle bearing , fresh outside cone bearing ( napa ) . my frequent reference to how easily does the pto down drive belt move ? is for real , that quickly verifies hoe easily its going to spin up , another thing I do is to just lightly engage it , never just slam it on , personally marvel at the pto lever clutch disk replacement . no screaming , spin up at all . always look for wide grease shields , makes removal , clean out / regrease easy . BTW have you enhanced the pto lever start , next to battery tray ? when I deal with a REPEDITIVE PROBLEM , I take it apart , stage by stage , find / change / improve , the issue , initially , you don't even , see it , but its function is amazingly smooth , easy , pete Share this post Link to post Share on other sites
