What This Product Does

This small sleeve forms a locating point within the applicable 915 gearbox casing assembly. When installed correctly, it positions the adjoining housing or shaft-related components in accordance with the original transmission arrangement.

Functions

• Provides a defined locating interface inside the gearbox assembly
• Assists alignment of the associated transmission components
• Supports accurate positioning when the casing is assembled
• Replaces an original sleeve that is worn, distorted, damaged or absent

Symptoms of Fault

• Scoring, deformation or other visible damage found during dismantling
• Unwanted movement around the sleeve location
• A missing locating sleeve discovered during transmission work
• Difficulty positioning the related components during reassembly

Transmission noise, leakage and poor gear selection can have many causes. Inspect the casing, shafts, bearings, seals and linkage before identifying this sleeve as the source of a fault.

Why Replacement Matters

A damaged or missing fitting bushing may prevent the adjoining transmission parts from being located as intended. Replacement is appropriate when inspection reveals wear, distortion or loss during dismantling. Related casing surfaces, bearings, circlips, seals and fixings should also be examined during a gearbox overhaul.

FAQs

• Is this the complete transmission housing?
  No. This is the individual fitting bushing or dowel sleeve shown within the housing assemblies.
• Where is the sleeve fitted?
  It appears in exploded diagrams covering the complete gear housing, front transmission casing, transmission suspension and transmission cover.
• What quantity is listed?
  The supplied diagram information specifies one for each applicable assembly.
• Is it suitable for every Type 915 transmission?
  No. The supplied catalogue context identifies 915/06/16/40/43/45/48 variants, so the transmission number must be checked.
• What else should be inspected?
  Check the surrounding casing surfaces and associated bearings, seals, circlips and hardware before reassembly.
