Claim 1
Independent Claim
131 words
A transmission arrangement for a vehicle having a longitudinal axis, a rearwardly disposed case, and a rear opening defined in said case, comprising: a housing assembly of a construction sufficient for extending forwardly through said rear opening and being releasably secured to said case about the periphery of said opening; a transmission having an output shaft located on said axis, said transmission being mounted within said housing assembly; a transfer gear train driven by said output shaft and mounted within said housing assembly; and a bevel gear and cross shaft assembly mounted within said housing assembly on a transverse axis located elevationally above said longitudinal axis and driven by said transfer gear train, said bevel gear and cross shaft assembly being located longitudinally between said transmission and said transfer gear train.
Claim 2
Dependent Claim
131 words
A transmission arrangement for a vehicle having a longitudinal axis, a rearwardly disposed case, and a rear opening defined in said case, comprising: a housing assembly of a construction sufficient for extending forwardly through said rear opening and being releasably secured to said case about the periphery of said opening; a transmission having an output shaft located on said axis, said transmission being mounted within said housing assembly; a transfer gear train driven by said output shaft and mounted within said housing assembly; and a bevel gear and cross shaft assembly mounted within said housing assembly on a transverse axis located elevationally above said longitudinal axis and driven by said transfer gear train, said bevel gear and cross shaft assembly being located longitudinally between said transmission and said transfer gear train.
Claim 3
Dependent Claim
29 words
