Sitrak C7H AMT Transmission Control Unit

Key Components and Their Functions

Handle Shifter & Shifter Bracket Assembly:
The handle shifter is the primary interface for manual gear shifts, designed for ergonomic use. It is securely mounted to the shifter bracket assembly, which ensures stable positioning and movement during operation.

Fasteners:

• Hexagon Head Bolts M6 & M8: The unit utilizes multiple hexagon head bolts—specifically, M6 for lighter connections and M8 for heavier-duty applications. These bolts are integral to securing different parts of the assembly.
• Type 1 Hexagonal Nut M6: This nut complements the M6 bolts to provide a tight and secure fastening solution.
• Spring Washers: Several spring washers are used in conjunction with the bolts and nuts to provide additional locking support and prevent loosening due to vibrations. Four spring washers are employed across various points of the assembly for enhanced stability.

Flat Washer & Dust Cover Assembly:
A flat washer is used to evenly distribute the load of the bolts, while the dust cover assembly protects internal components from debris and contaminants, ensuring a longer service life.

Pressure Plate & Shift Guard:
The pressure plate is essential in engaging and disengaging the clutch during gear shifts. The shift guard protects the shifter mechanism from damage and ensures safe operation by preventing accidental gear disengagement.

Shifter Cover Assembly (Wide Body):
The shifter cover assembly (wide body) encloses the shifting mechanism, protecting it from external elements and providing a sleek, finished appearance.

Connecting Plate Assembly:
The connecting plate assembly ensures that various components of the control unit are linked effectively, enabling smooth and synchronized operation between the shifter and the transmission system.

Blind Rivet Nut M8:
Two blind rivet nuts M8 are used for secure blind-side fastening, providing a robust solution for areas where access is limited.

Shift Hole Cover & Plug Cover:
The shift hole cover protects unused or secondary shift positions, while the plug cover seals off any unused ports or openings to prevent dust and debris ingress.

Shift Knob Switch:
The shift knob switch is the final component that the driver interacts with, allowing for manual gear selection. It is designed for ease of use and durability.

Additional Fastening Solutions

Cross Recessed Pan Head Tapping Screws and Flat Washers Assemblies:
Two sets of cross recessed pan head tapping screws and flat washers are utilized for precise and firm attachments in critical parts of the assembly. These screws provide easy driving and secure fastening, with the flat washers ensuring load distribution.

Reed Nuts:
Two Reed nuts are included in the assembly, providing a secure threaded insert for softer materials or where traditional nuts might not be suitable. Specifically, one Reed Nut is used for specialized fastening needs, ensuring that all components stay firmly in place.
