Flywheel housing access hole 1.25″ diameter for Cummins R2.8

Description

This kit is required when mating an Allison 1000 transmission to the Cummins R2.8. This hole is needed to access the torque convertor-to-flexplate bolts.

The Quick Draw access hole kit is comprehensive and includes everything you need to make this minor but necessary modification.

Kit includes:

  • Jig to locate hole 11.5″ from the crankshaft center line
  • Vented plug to access bolts on the back side of the flexplate for the Cummins R2.8,
  • Optional New Colbalt Step Drill bit

Note that the hole diameter is 1.25 inches and that the vented plug edge may need slight trimming due to casting.

If you choose to include the optional stepped drill bit, simply use the bit to drill to the second to last step, which is 1.25″ diameter.  Than use the 1-3/8″ part of the bit to make a slight chamfer so the hole plug seats and stays in the hole.
