Cmike 0 #1 Posted June 9, 2012 Hello...New to this forum, but I have a 1975 D200 and the coupling and the transmission shaft both stripped out at the same time..I located a new shaft and have reinstalled it..My problem is I can not locate the correct seal. The one that cross references doesnt seem to be a high pressure seal and of course it leaks.Does anyone know where i can purchase the correct one..All help appreciated.

pfrederi 17,881 #2 Posted June 9, 2012 Toro number 7877 equates to National 480821 or CR 7474. CR 7475 has a double lip same size. Which one did you use? This is not a high pressure setting. the pump housing is merely a reservoir for the charge pump. Any pressurized area would have to use O rings not just a seal.

Cmike 0 #3 Posted June 10, 2012 We used the CR7474..We were not able to locate a CR7475. We were concerned that it was only a single seal but were told it would be ok. Do you know where we could purchase a CR7475? Thanks for your help..Truly appreciated.. Share this post Link to post Share on other sites

Is this it? http://www.ebay.com/...ain_100&vxp=mtr Here is an ebay search for that seal: http://motors.shop.ebay.com/i.html?_nkw=7475+Seal&_sacat=&_dmpt=Motors_Car_Truck_Parts_Accessories&_odkw=7475&_osacat=0&bkBtn=&_trksid=p4506.m270.l1313 Mods - sorry about the ebay links. I hope it doesn't cause any problems. If so, let me know and I will remove it. James Share this post Link to post Share on other sites
pfrederi 17,881 #6 Posted June 11, 2012 That is a good price. The other guys are out of line. My supplier would be about $10 Share this post Link to post Share on other sites
pfrederi 17,881 #7 Posted June 11, 2012 The more i look at the seal profile on 7475 to me it looks like the outer seal edge is designed to keep dirt out rather than oil in.... Was the shaft surface where the seal rides in good shape??? Sorry about upload picture for some reason it turns teh back ground black but look at the small white box. link to SKF http://www.skfextranet.com/catalogs/457010/sealdetail.asp?s=7475 Share this post Link to post Share on other sites
