Middlesex County, Ontario | We have a Pequea single rotor rake. The center gearbox, wobble box, cam box, or whatever you want to call it, is oil filled.
The oil is completely full of metal shavings. Last year I flushed the box with diesel and oil and got out what I could. I had flushed it a previous year also. This year the box is full of shavings again.
Shavings in oil don’t leave a good feeling.
I have had to replace a couple stub arms coming out of the cam box, so I know what the inside looks like. The cams rollers are metal and ride on a shaft without bearings. The stub shafts are steel shafts in an iron bushing. There’s a lot of metal to metal contact going on. Other rakes we have had in the past were mechanically similar, but did not have an oil bath and the rollers had bearings. I think every other rake we have owned had the roller cams exposed and there was just a ton of grease down there. I would think that grease would hide shavings pretty well.
Being that it’s all metal to metal contact and there’s no opportunity for shavings to shed the box like there would be with grease, would you agree that shavings in oil are normal for this application?
