Guide wheel 150.32.011-1A assembled

The 150.32.011-1A guide wheel assembly is used in the chassis of HTZ tracked tractors and is designed to guide, tension and maintain the correct position of the track chain. Among machine operators, this unit is widely known as “sloth”.

The unit is installed as part of the tension and damping mechanism of the caterpillar propulsion unit and is used in the amount of 2 pieces per tractor. The basis of the assembly is the crank axle 150.32.012-3, on which the guide wheel 150.32.150 is installed. The design of the unit ensures smooth operation of the track, reduces shock loads and helps to increase the service life of the chassis.

The assembly unit 150.32.011-1A includes the main parts:

• crank axle 150.32.012-3;
• axle 150.32.022-2;
• guide wheel 150.32.150;
• axle 150.32.153;
• adjusting gaskets 150.32.157;
• cap 150.32.158;
• ring 150.32.168;
• cover 77.32.104;
• gasket 77.32.106A;
• thrust washers 77.32.110 and 85.32.113;
• spacer sleeve 77.32.117;
• nut 85.32.114;
• seal housings 85.32.025 and 85.32.203;
• bearings 7311K and 7513;
• sealing and locking rings of the A11.00.103-01 – A11.00.108-01 series;
• fasteners, washers, cotter pins and oil can 1.3.Ts6.

The proper condition of the idler assembly directly affects proper track tension, track wear, and the durability of suspension components. Timely replacement of worn parts helps maintain the efficient operation of the chassis and reduces operating costs.

It is used on HTZ T-150G tracked tractors and other equipment with a similar design of the chassis and track tensioning mechanism.
