  • T20 Skid Steer Rebuild


    Let’s start by reassembling the clevis and bands. If you will notice there are two different bands. One has the plunger on top and the anchor point on the bottom while the other is the reverse. You want the plungers to be closest to one another in the center of the transmission so the first band should have the anchor point at the bottom.

    Put the band and plunger with no o-rings into the T-20 transmission case. Apply a liberal amount of vasoline on the plunger and slide it through the housing from the inside all the way through to the outside. You may have to install the plunger bolt and pull it through from the outside to get it there.


    Then you want to coat the new o-rings liberally in vasoline and slide them on the plunger into the appropriate grooves.


    TIP: Next we will be pushing the plunger back into the housing. Before doing so I recommend putting the bolt and rectangular washer from the brake lever back onto the plunger. Without it, it is easy to accidentally push the plunger back into the inside of the housing. If you do this later in the assembly by mistake and try to push it back in from the inside of the housing you will most likely tear the o-rings and they will not provide a good seal.


    Repeat the process and install the upper band. That band should have the plunger towards the bottom (or outside) of the housing and the anchor point near the top (or center) of the housing.


    Install the new bearing.


    Install the bearing lock ring by walking it around the groove.


    Install the oil seal. Make sure that you gently tap the seal in place in an even manner or you could risk damaging the seal.


    Optional step – The reason that I had to rebuild my transmission was because a main seal worked it’s way out of the transmission housing. In order to hopefully prevent this in the future, I took a punch and pinged the housing in several places to help hold it in place. This day I only had a small punch. If you will read on to the other side’s reassembly I have the correct sized punch and only hit the housing in four places with it.


    Now you can install the output shaft from the outside of the T20 skid steer housing.


    You may have to gently tap it until it goes in place.

    • Rework an Early T20 to Accept Thrust Washers
      by whipper-ag
      I'm sure that some of you have opened up some Early T-20's & found them FUBAR. Once the gears start digging into the drum face, it doesn't take long to ruin the bearings, wear the bands down & cause excessive wear on the ring gear. Fortunately, all is not lost. In most cases, it can be modified to add the fiber thrust washers which are now used in the Late Model T-20's. Here's a video how to do it.

    • Max II T20 Split Shift Modification Video
      by LarryW
      This is a how-to video for making a split shifter for your T20. While I did the modification on my Max II, the same principals will apply on most Borg Warner Skid Steer T20 transmissions regardless of which ATV it is in. Instead of having one lever that controls shifting of both sides this mod will let you shift each side of the transmission independently allowing you to counter rotate. I even got to scare myself a little.

      Borg Warner T20 Transmission Rebuild A large percentage of 6 wheelers utilized the Borg Warner / Skid Steer T20 transmission. While they are virtually indestructible when properly maintained many of these skid steer transmissions have been around for over 30 years. It is only natural that at some point in their life whether it is due to improper maintenance or old age, they will need new seals, bands, drums, o-rings, or bearings. This article will walk you through a tear-down and re...

    • Salsbury Clutch Rebuild
      by Don
      How-To rebuild your Salsbury Clutch Salsbury was a very popular brand of clutch system for many of the amphibious ATVs from the 1960s to around 1980 when they closed up shop. Attex, Hustler, Scrambler and Max used them on at least some of their models, and I'm sure more of the lesser known machines used Salsbury as well. Attex used model 910 for the ST400, Chief, Thunderchief and Superchief and the 780 for most of it's single cylinder two-strokes. I'll try and be clear on how to do a...
