Any 'Lodge PT/WBs with Jake Brakes?

[snowbirdtogo]

Ben,
I have a Jacob's engine brake (two stage) on my 6V92. Last summer
drove over Eisenhower pass but had no trepidation with the 15 mile 6-
7% grade going down west side. On my coach it is barely audible.

on your Detroit Diesel Silver 330 (1982-84 6V-92TA), Silver 350 (1985-
89 6V-92TA), Silver 475 (1986-89 8V-92TA) or Silver 500 (1990-95 8V-
92TA)?

compression-release engine brakes. Its initial development was
started in 1931 by Clessie Cummins (the founder of Cummins Engine
Co.), and handed down to his nephew Don Cummins, son of Clessie's
brother Deloss. The elder Cummins was looking for a way to bring his
heavy-duty diesel trucks to a stop without excessive engine wear. 30
years on, the official Jake Brake compression-release engine brake
entered production.

type and how well it is maintained. It was this aspect that caused
many cities to ban the use of Jake Brakes in certain parts of the
town. But not all Jake Brakes sound like this, though. The RAT-A-TAT-
TAT-TAT sound would refer to the compression-release Jakes, not the
exhaust ones.
