[Farmall] Farmall Cub - Noise in 1st Gear Under Load

[Roger Moffat]

Hi All - is this thing still on?

I have a Farmall Cub Serial 82115 that I've been using for some cultivation yesterday. It doesn't get a whole lot of use - probably less than 10 hours a year.

It has quite a "noise" when under load in 1st gear - kind of 

wah wah wah noise.

Does anyone know if this is likely to be one or other of the gears, or is it maybe a bad bearing?

There's plenty of oil, and it looks pretty clean from when I last changed it - albeit that was probably more than 10 years ago.

Thanks

Roger
