TRACK CARRIER ROLLER
1. Shaft. 2. Duo-Cone seal. 3. Bearings. 4. Passage. 5. End cover. 6. Plug.Lubricant is sent into center passage (4) through the 5M2080 Nozzle. The lubricant fills the cavity between shaft (1) and the roller. When the cavity is full, the pressure of the oil causes the air and extra lubricant to go out the relief threads in the nozzle.When the lubricant does not have any bubbles, remove the nozzle and install the plug. Tighten the plug to a torque of 125 15 lb. ft. (170 20 N m).Track Rollers
The track rollers are fastened to the track roller frames. The track rollers are in contact with the inside surfaces of the track links. Flanges on the track rollers prevent the movement of the track from side to side. The inside surfaces of the track links cause an equal distribution of the weight of the machine along the track.The flange at the center of shaft (5) gets the side load on the roller. Bearings (3) also get the side load on the roller. The amount of side movement or end clearance of the shaft can not be adjusted.The track rollers have Duo-Cone floating seals (6) at both ends of shaft (5).Each track roller frame has six track rollers except for LGP Tractor. LGP Tractors have seven rollers. The installation of six track rollers is as follows: 1. Start at the front of the machine and install one double flange roller. 2. Then install one single flange roller. 3. Then install one double flange roller. 4. Then install one single flange roller. 5. Then install one double flange roller. 6. Then install one single flange roller.The installation of seven track rollers is as follows: 1. Start at the front of the machine and install one single flange roller. 2. Then install two double flange rollers. 3. Then install one single flange roller. 4. Then install two double flange rollers. 5. Then install one single flange roller.

If lubricant is added with the roller removed from the machine, shaft (1) must be in a horizontal position. The slot, in the end where the 5M2080 Nozzle is installed, must be down.Lubricant is sent into center passage (5) through the 5M2080 Nozzle. The lubricant fills the reservoirs (4) in the rollers. When the reservoirs are full, the pressure of the oil causes the air and extra lubricant to go out the relief threads on the nozzle.

The front idlers put the tracks in position in front of the track rollers. They also keep the tracks in alignment with the sprockets.The adjustment of the tracks is
