I am the proud owner of my great-uncles MF135. It was purchased new in 1967, always stored in the barn. I checked the oil level in the transmission today and it a little bit above the fill line and looks like new. According to the owners manual I need to add MF brand oil. Is that just a 90W gear oil? I have no idea what is in there right now so I am not sure what to top it off with. Any idea how much it will take to bring it up to the full level? I know for the engine the difference between the two lines is 1 quart. What is it for the transmission? The oil is a minimum of 10 years old but it honestly looks like it was changed yesterday. Maybe I should just drain it all and start from scratch?
Second question, I was told that behind this round access panel is a filter. Is there any truth to this? The owners manual does not mention anything about a filter. If there is a filter will this cover simply come right off even with the lever attached to it? Any trick I should be concerned with? Will oil come out if I remove this cover or does the oil sit lower?
Thanks
