Cover assembly

Cover assembly is the main housing that encloses the shift mechanism and provides mounting points for all control components. It is a fundamental part of the Gears switch cover composite member.

Sheath

Sheath is a plain bushing that supports shift shafts and reduces friction. It ensures smooth linear movement within the composite member.

Sheath SF2 25x28x20

This is a composite bushing with a self‑lubricating lining, providing low‑friction support for rotating or sliding elements in the Gears switch cover composite member.

LOCTITE glue

LOCTITE glue is a thread‑locking compound used to secure fasteners against vibration. It is applied to critical bolts within the composite member.

Plug

Plug is a sealing plug that closes unused openings, preventing oil leaks and ingress of dirt.

Hex bolt

Hex bolt is a standard threaded fastener used to secure the cover and other components. It provides reliable clamping force.

Spring washer

Spring washer prevents bolt loosening due to vibration, maintaining joint integrity in the composite member.

Self locking spring

Self locking spring applies pressure to the shift detent mechanism, ensuring that the selected gear stays engaged.

Spring block

Spring block is a retainer that holds the self‑locking spring in position, ensuring consistent detent force.

Roller rod

Roller rod is a cylindrical pin that acts as a pivot or guide within the shift mechanism.

Self lock shaft

Self lock shaft is the pin that carries the self‑locking mechanism, providing detent action for gear positions.

Driving rod

Driving rod transmits motion from the shift lever to the internal shift shafts, enabling gear selection.

Gear shaft assembly

Gear shaft assembly comprises the main shift shaft and associated springs, providing the core shifting function of the composite member.

Shift shaft

Shift shaft is the primary rod that moves the shift forks to engage gears. It is a critical part of the Gears switch cover composite member.

Spring

Spring provides centering force for the shift shaft, returning it to neutral when no gear is selected.

Base ring

Base ring is a spacer that supports the shift shaft springs, maintaining correct preload.

Retainer

Retainer is a snap ring that secures components on shafts, preventing axial displacement.

Fan shape self locking block

This block provides a positive detent for gear positions, giving the driver tactile feedback during shifts.

End plate assembly

End plate assembly seals the end of the cover, housing the shift shaft and oil seals. It is a key sealing component.

Air plug

Air plug (breather) equalises internal pressure, preventing oil leaks while keeping contaminants out.

Oil seal

Oil seal prevents lubricant leakage along the shift shaft, protecting the environment and ensuring proper lubrication.

Sensor drive ring

Sensor drive ring rotates with the shift shaft, providing position feedback to the transmission control unit.

Elastic round rod

Elastic round rod is a spring pin used for secure fastening in applications requiring vibration resistance.

I shape Hex nut

I shape Hex nut is a standard nut used with bolts for reliable clamping in the composite member.

Wave spring washer

Wave spring washer provides axial preload, maintaining tension in assembled components and reducing play.

Swing arm

Swing arm translates shift cable motion into shaft rotation, enabling remote gear selection.

Dust cover

Dust cover protects the shift shaft entry point from dirt and moisture, preserving seal life.

End plate gasket

End plate gasket seals the end plate to the cover, preventing oil leakage.

Support level

Support level is a mounting bracket that provides additional rigidity for the shift mechanism.

Support axle

Support axle is a pivot pin that allows the shift linkage to move freely.

Rod

Rod is a connecting pin used in the shift linkage to transfer motion.

Locking fork

Locking fork engages with the shift shaft to prevent simultaneous selection of two gears.

Locate sleeve

Locate sleeve is a guide bushing that ensures precise alignment of shift shafts.

Glue

Glue (thread-locking compound) is applied to fasteners for secure, vibration-proof connections.
