Question: Are the operating con

severe as those encountered In tbs
fabrication Of internal combustion
engines?
Answer: While the operating
conditions encountered in transmits
sion and rear axles OF automobiles
farm tractors and similar machines
are not as severe as those encoun
tered in the fabrication OF interna
combustion engines, they present
however, problems which demant
serious consideration.
Owing 10 the peculiar construction
OF these mechanism. where hIgt
speed revolving shafts pass directly
thru the case. the problem OF pre-
venting leakage necessitates the u5t
Of highly viscous oils and often tbs
Use OF gear compounds.
