[GreenKeys] Kleinschmidt TT-4C

[Duncan Brown]

Peter,

A great find! I have always liked the TT-4, It's a basic unit and 
(relatively) easy to work on. I spent my year in Viet Nam working on them.

The main lubrication points are to oil the felt washers in the clutches 
and grease the gears.

A better scan of TM 11-5815-206-35 can be found at Google Books. But 
they did not bother to unfold the fold-out pages!  So you will need both 
scans.

Have fun,
