Carriage Seal Housing 85.31.026

Carriage Seal Housing 85.31.026 is used in the undercarriage of HTZ and DT-75 crawler tractors. It is designed to seal the Carriage Assembly 151.31.012-1, preventing dirt, dust, and moisture from entering the assembly. Effective sealing significantly reduces wear on moving components and helps extend the service life of the undercarriage when operating in harsh conditions.

The housing is installed on the Balancer 150.31.102-1 and is secured with four bolts through four mounting holes. Each tractor is equipped with 4 seal housings, one for each undercarriage carriage.

The Seal Housing Assembly 85.31.026 consists of:

• Seal Housing 85.31.133
• Seal Ring A11.00.107
• Rubber O-Ring 080-086-36-2-2

Together, these components provide effective protection of the carriage's internal parts against contamination while retaining lubricant inside the assembly. This is especially important when the tractor operates in dusty, muddy, or wet environments.

During undercarriage maintenance or overhaul, it is recommended to inspect the seal housing, sealing rings, and the balancer mounting surfaces. If wear, damage, or loss of elasticity of the sealing elements is detected, the complete Seal Housing Assembly should be replaced to maintain proper sealing and prevent premature carriage wear.

Carriage Seal Housing 85.31.026 is compatible with HTZ T-150, T-150-05-09, HTZ-181, DT-75, and other crawler tractors equipped with the same type of undercarriage carriage assembly.
