Crmaverick 91 #1 Posted December 13, 2020 (edited) I’m wondering what the differences are between these transmissions? Is one better than the other or have any advantages? I picked up a 5049 today while looking for wheels and tires I ended up with the whole axle with wheels and tires. How’s this trans compare to the 5053 in my 67 Lawn Ranger? And the 5025 in my 753 can they be direct swapped? Edited December 14, 2020 by Crmaverick 1 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,095 #2 Posted December 13, 2020 They all come up in this link https://www.wheelhorseforum.com/search/?q=5049&quick=1&type=downloads_file One year (1964?) they all got new shift rails and that generated new model numbers. I believe the bend in the shifter to clear the hydraulic pump may have changed the model numbers. Not sure on this one. At one point the replacement transmissions came without a shifter which may have produced new model numbers. The two-piece pinion gears where changed to one piece but I forget when. That would be a huge improvement. Garry 2 Share this post Link to post Share on other sites
Terry M-(Moderator) 2,176 #3 Posted December 14, 2020 I notice a casting difference in the 5025's compared to the others... Share this post Link to post Share on other sites

Crmaverick 91 #5 Posted December 14, 2020 I saw in the manual the 5048 was weak in some way that they offered an upgrade kit to make it a 5053. Anyone know what the difference is between a 5049 and 5053? Share this post Link to post Share on other sites

It’s just a cosmetic difference near the rear axle bearing area is. If all my stuff wasn’t stored for the winter I’d take a pic for you. 1 Share this post Link to post Share on other sites

The 5025 are quiet, wasn’t sure if the 5053 had beefier gears Share this post Link to post Share on other sites
stevasaurus 22,862 #8 Posted December 14, 2020 All of the 3 speed uni-drive transmissions have the same gears and parts...5007,5025, 5046, 5048, 5049, and 5053. The only real difference is the shift rails got a flat side to them to solve the suction problem (which put the trans into 2 gears at the same time). Non of the gears are beefier and the pinions are all 2 piece. I've taken apart a 5007, and a 5025 and I did not see anything different...maybe a different size drain plug or fill plug then the later transmissions in this group?? The 5046, I believe, is the one that first had the flat side shift rails. The 5048 is for Lawn Rangers...the difference...maybe axle length?? Any difference between the 5049 and the 5053...if anything, it is not worth finding out. The 5053 became the replacement transmission for all of the above transmissions. Maybe the difference is the 5053 did not come with the shifter, boot, dog point set screw, lock nut and knob...the 5049 did. There is a part number cast into both sides of the case halves. The right side is #3900...the left side is #3901. You can see the 3900 in the above RH casting. The case halves are the same part numbers for all of the above transmissions. #5007 case halves #5046 #5025 My question is...How do you know it is a #5049?? Did the guy tell you what horse it came out of?? That is really the only way to know. Share this post Link to post Share on other sites

Did the guy tell you what horse it came out of?? That is really the only way to know. I checked that book and matched up the 1965 655 with the 5049 trans. I actually took it off the 655 myself, separated the trans from tractor frame when I was there. He wanted 40 for a set of wheels and tires and 50 for the whole trans + wheels, so I just took the whole unit, with the lift cable and rear hitch to. Guess I have a spare if I pop my trans working the 753 or 704, but I don’t see that happening, these things seems pretty bullet proof.

Crmaverick 91 #10 Posted December 15, 2020 I also noticed this axle also has 5 lug hubs, what was the purpose of that are they any stronger? I can’t really see any scenario where the 3 lug would be weaker or break vs the 5? 1 Share this post Link to post Share on other sites
stevasaurus 22,862 #11 Posted December 15, 2020 I don't know if the 5 is stronger then the 3. I've destroyed both kinds trying to get them off of axles. I can't say they look any better then the other, because you can't really see them when the wheels are on. Maybe, guys just got tired of hearing that they were missing a couple of lug bolts. I've got 2 of these transmissions for spares also...and 2 horses that use them. They are bullet proof. Just know that all of the parts are interchangeable in this group of transmissions. That's what I mean. If you pulled the trans off of a particular horse, and it looks like it has never been touched, then it is a good bet you have a #5049. 1 Share this post Link to post Share on other sites
