PROBLEM

Show/hide table

The existing transmission arrangement clutch 1 and clutch 2 can fail in certain 797 and 797B Off-Highway Trucks. Clutch 1 and/or Clutch 2 can fail due to excessive clutch slippage and excessive heat generation which compromises the life of the clutch friction material. If the existing transmission fails it will result in a loss of drive and poor component life.
