Use M-533 oil in the dual high assembly, when the assembly is operated at temperatures of 10 and above zero or colder M-5333 oil should be thinned with 10% kerosene. Approximately one quart of oil is required to bring the oil level up to the “F” (full mark) on the oil level indicator. The oil level should be checked every 1,000 miles and an additional oil added if required. Every 5,000 miles the old oil should be drained out and replaced with fresh M-5333 oil.

Floor boards used in cars having the original hand brake equipment will not be varied for service.

Should it become necessary to replace floor boards in one of these cars, use the present design floor board together with floor board emergency lever plate, part 35245B, to cover the opening in the boards. (See Fig 572).
