| Oyl-W-22023 -2- now getting some pen steel discs .010 thick for a test. Even though the fabric is quite O.K., one feels it would be more of a mechanical job to use steel discs if the results are equally good. When the gears are for any reason run in on the engine with the oil flow pipe disconnected and the wheelcase removed, one can hear a slight pinion rattle at one speed, but with plenty of oil on the gears this does not occur.
