Allison Transmission 4000 B500 Series 4K Technicians Guide

Online pdf Allison Transmission 4000 B500 Series 4K Technicians Guide

The Technicians’ Guide is intended to provide additional guidance with the inspection and analysis of transmission parts. This guide should be used by technicians who overhaul Allison 4000/B 500 automatic transmissions in conjunction with the 4000/B 500 Service Manual (SM2457EN) when inspecting parts 
to determine their serviceability and reuse.

General Rework Guidelines
Replace parts that cannot be re-worked as outlined in this manual and Service Manual SM2457EN.  A soft stone or crocus cloth can be used to attempt removal of “high spots”  from transmission parts. After the attempted rework, the part must meet specification if it is going to be reused. Some seal surfaces (for example the output yoke sealing surface and  the converter pump hub sealing surface) cannot be reworked. 
Both of these seal surfaces have a controlled finish that can result in a fluid leak if the part is altered by rework.
