kudzu3 323 #1 Posted February 3, 2015 I have a leak at the brake shaft in my '74 B 80, the best I can figure it out, it is a 5053 trans, 4 speed uni drive. In the reference numbers posted, it appears that this seal would be sks 9815, so that is what I ordered. I found that this is not the correct seal, maybe should've gotten a sks 7410. Am I correct with the 7410? I'm trying to figure out how I mis read the numbers, but seems that I read them right. I'm a little confused here, probably my fault but could some one offer an explanation? Share this post Link to post Share on other sites
rmaynard 14,932 #2 Posted February 3, 2015 If you have a 1974 B-80 4-speed, the Toro number for the brake shaft seal is 100441 or SKF 7410 Share this post Link to post Share on other sites
rmaynard 14,932 #3 Posted February 3, 2015 Your tranny should be a 5084. 1 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 10,530 #4 Posted February 3, 2015 Toro tells us the two models of 1974 B-80 4-speeds use the 5084 transmission. If you go to the transmission service manual the model 1-0140 uses 5080 transmission (I believe this one uses 2-piece pinion gears) the model 1-0145 uses 5084 transmission (I believe this one uses 1-piece pinion gears) In any case they both use the 100441 seal for 3/4" brake shaft = SKF 7410 Garry Share this post Link to post Share on other sites
kudzu3 323 #5 Posted February 3, 2015 Yes, it is 5084, my mistake. So seems like we all agree that it is skf 7410. Thanks all. Share this post Link to post Share on other sites
