Contaminated gear oil
Changing the transmission gear oil in my '48, noted microscopic steel flakes in the old oil. Total amount was less than a half thimble full. No operational problems. Oil not blackened. Is this a sign of normal wear?

Re: Contaminated gear oil
I would be tempted to take a look inside. If you don't, do put in a magnetic drain plug.
I put one in the fill hole (also)- the thought is that one could pull it without draining the oil. Karl |

I hope/assume you haven't changed the Tranny in a long time. If its been a short time I'd be concerned about that much ground-metal in a short time period.

Re: Contaminated gear oil
Using GL-4 85W90. Been in there a long time. Are there magnetic drain plugs available to fit a '48 transmission?
