Dirtybug 0 #1 Posted January 30, 2011 I just picked up a 551, The first thing I noticed was that the axle seals are leaking there is also a bit of forward backward movement of the axles (about the width of a paperclip) Do I need bushings aswell? The only #"s I've found on the trans are 2988185 (on tag) and 3800 (cast in) If I need bushings can the be removed / installed wth the trans assembled and axles in place?

TT-(Moderator) 1,127 #2 Posted January 30, 2011 :banghead: Some in & out movement is normal. Up & down movement is what you DON'T want. All seals can be replaced without disassembly, but none of the bearings can. If you need bearing & seal numbers, read through at the topic pinned at the top of this section.

Dirtybug 0 #3 Posted January 30, 2011 :banghead: I believe I've found the trans is a 5053? I have no up and down movement of the axles but they move forward and back also in/out a bit. If I need bearings but dont do it will the seals just leak imediatly again. If I have the correct trans model I've found seals and bearings from partstree ??anybody use them before??

TT-(Moderator) 1,127 #4 Posted January 30, 2011 It should be a #5007 Uni-Drive. Although PartsTree does sell the bearings and seals, your local dealer and/or other parts stores can get them too - sometimes cheaper. Share this post Link to post Share on other sites
stevasaurus 22,229 #5 Posted January 30, 2011 :thumbs: All of the Uni drive transmissions are pretty much the same. If you have not found it already, here is a link to my rebuild: http://www.wheelhorseforum.com/index.php?showtopic=17168 As Terry said...you may get by with just the seals...ask any questions and/or post some pictures and we will walk you through it.: Here is a link to the trans manual.: http://www.mywheelhorse.com/graphics/file/...ns/492-4004.pdf Let us know. :banghead: Share this post Link to post Share on other sites
Dirtybug 0 #6 Posted January 31, 2011 Thanks for the links. I'm going to try just replacing the seals and see what happens, If they leak again I'll do a teardown. How would I find out which trans this is? I see two listed for the 551. Or are all the seals the same. Share this post Link to post Share on other sites
TT-(Moderator) 1,127 #7 Posted January 31, 2011 The 551 and 701 used the two-piece #5007. The 401 used the three-piece #5010. Share this post Link to post Share on other sites
stevasaurus 22,229 #8 Posted January 31, 2011 :banghead: Guessing...but I think the seals are the same. Share this post Link to post Share on other sites
Dirtybug 0 #9 Posted January 31, 2011 cool, I'm gonna swing by a few stores tommorow and see if anybody local has the seals. Share this post Link to post Share on other sites
stevasaurus 22,229 #10 Posted January 31, 2011 If you can't find them at a NAPA or something...Motion Industries has them...they used to be Berry Bearings. You may have to order them...takes a couple of days. :banghead: Share this post Link to post Share on other sites
Dirtybug 0 #11 Posted January 31, 2011 Thanks! NAPA's site shows the seals for near $50 each, they don't look right though so I'll check in store to see what they've got. While I have your attention, anybody know the dimensions for the front wheel bearings? I saw it listed in a post but that was days ago and can't find it now.
