48 Cub - new fluids, oil pressure guage
Posted: Sat Oct 09, 2021 2:49 pm
I got a 48 Cub this week, from a neighbor (who picked it up at an auction). As I am changing fluids, I noticed that the oil pressure gauge is full of oil behind the glass. Seems like this should be replaced. The gauge is under the gas tank on the side of the oil filter. Is it common to leave it there or move it to the dash where there is an unused location for a gauge. While I would like to maintain originality it is more important to me to have good functionality as I intend to work this Cub.
I also noticed that the filter drain tube was caked full of several inches of dry crusty gum. When I broke through it then a bit of oil drained out. Is this common? Any thoughts on whether I should take additional steps to clean out the engine, other than simply an oil change using specs form the latest manual. I am inclined to simply do the oil change, and possibly increase the frequency of oil changes, initially.
As I drove it home (~ 1/2 mile), I noticed a low frequency, but loud noise, that came and went, from the front area. In reading the manual and checking the 'brought an new cub home' check list, I am guessing the noise is due to lack of lub in the fan hub. It did seem to be dry so I put some gear oil in it. What is the purpose of that oil reservoir? Does the fan change rotation based on temperature or something.
Thanks for the advise. Phill
