Thread Repair Criteria:
Prior to beginning the field modification procedure, the filter cover bolt holes must be inspected to assure the MI0 Step Driil (1-42385-231) can properly prepare the bole for thread cutting with the Tap J-42385-232. If any of the filter cover bolt holes are found oversized the transmission main housing must be replaced.
NOTE: The Allison factory installed steel inserts use the same hole and thread size as the Thread Repair Kit inserts; however, the MlO Step Drill J-42385-231 must be used to counter-sink the hole before the
Thread Repair Kit inserts are installed.
Field Modification Procedures:
The attached SPX Kent-Moore instruction sheet must be used to facilitate the repair of the filter cover bolt threads in the main case.
