Original Cat 16 Grader Specs

I only have engine, driveline and controls specifications, not overall machine.
Looks like tires can be an issue, might plow through this HEF discussion

I have a 16 49G269. So far we have changed the head and rad core. The cooling system holds 21 gal. We Are also changing the transmission fluid. Trans fluid is 30 weight. Ours has a different tire than listed. When I get to my bolt later I can give you some informations

Cat 16 49G series made from 1963-1973, 225 hp, approx. shipping weight 49,600 lbs, wheel base 22' 6", length 31' 2", width 9' 10", moldboard length 14', turning radius 44' 6", max speed forward 30.9 mph
Cat 16G 93U series made from 1973-1995, 275 hp, approx. shipping weight 60,150 lbs, wheel base 22' 10", length 32' 8", width 10' 1", moldboard length 16', turning radius 27', max speed forward 27.1 mph

I believe the 49G would have had a D333 engine then went to the 3306. Not sure though.

The 16 49G uses the D343T @225 hp
The 16G 93U uses the 3406T starting at 250 hp and later was raised to 275 hp
