CARRIAGE OEM 124535 124536 for NOV TDS-11SA Top Drive

The CARRIAGE, 30'' SETBACK, DS, with OEM Ref. 124535 (Left) and 124536 (Right), is an important structural and guiding component of the NOV TDS-11SA top drive system. Linhai Evergrow supplies these replacement components as Evergrow Part #186803 for the left-hand carriage and Evergrow Part #186804 for the right-hand carriage.

These two carriage components are used as part of the corresponding CARRIAGE ASSY LEFT 124538 and CARRIAGE ASSY RIGHT 124539 configurations. The 30-inch setback version is specifically identified in the TDS-11SA spare parts information, making accurate part-number identification important when planning top drive maintenance or replacement.

Product Information

Left Carriage

Right Carriage

Evergrow's published TDS-11SA parts list identifies 124535 as the left 30-inch-setback carriage and 124536 as the right 30-inch-setback carriage. It also lists the associated left and right carriage assemblies.

Carriage Components for TDS-11SA Top Drive

The carriage system is part of the mechanical structure that guides and supports the top drive in relation to the guide beam assembly. The complete carriage assembly incorporates the carriage, bogeys 124537, cam followers 30155438 and 30158767-04, bearings, bushings, pins, fasteners, and other associated components.

For the 30'' setback configuration, the individual left and right carriage components are identified by separate OEM references. This is important because the TDS-11SA also uses carriage configurations with other setback dimensions, including 33.75'', 39.50'', and 41.00''.

Therefore, a carriage intended for one setback configuration should not be selected solely because it has a similar appearance. The original OEM reference and required setback should be confirmed before ordering.

124535 and 124536 in the Carriage Assembly

The 124535 left carriage and 124536 right carriage are individual components associated with the larger carriage assembly.

The TDS-11SA carriage assembly also includes components such as:

· Bogey: OEM Ref. 124537

· Cam Follower: OEM Ref. 30155438

· Bearing, Cam Follower: OEM Ref. 30158767-04

· Flanged Bushing: OEM Ref. 109944

· Pin, Bogey: OEM Ref. 112875

· Jam Nut: OEM Ref. 80569

· Carriage Assembly, Left: OEM Ref. 124538

· Carriage Assembly, Right: OEM Ref. 124539

These components are identified together in published TDS-11SA carriage parts information.

When repairing a carriage system, inspecting the associated bogeys, cam followers, bearings, bushings, pins, and fasteners can help identify other components that may require attention.

Why the 30'' Setback Configuration Matters

Setback dimensions are an important part of identifying the correct carriage configuration. The TDS-11SA parts information includes several carriage versions for different setback requirements.

For the 30-inch configuration, the relevant references are:

· 124535: CARRIAGE, LEFT, 30'' SETBACK, DS

· 124536: CARRIAGE, RIGHT, 30'' SETBACK, ODS

· 124538: CARRIAGE ASSY, LEFT, 30'' SETBACK

· 124539: CARRIAGE ASSY, RIGHT, 30'' SETBACK

The published parts information distinguishes these from the 33.75'', 39.50'', and 41.00'' configurations.

This makes the OEM reference, left/right orientation, and setback dimension three important details to verify before purchasing a replacement.

Inspection and Maintenance of TDS-11SA Carriage Components

The carriage system operates in a demanding drilling environment and should be included in regular top drive maintenance inspections.

Particular attention should be given to the condition of the carriage and its associated rolling and guiding components. Maintenance personnel should check for visible damage, abnormal wear, looseness, damaged fasteners, and unusual movement.

Published TDS-11SA maintenance information also emphasizes inspection of carriage-related components such as bogey rollers, cam followers, dowel pins, and fasteners.

If excessive wear or damage is found, the affected component should be evaluated according to the applicable maintenance procedure before the top drive is returned to operation.
