I have a late model 509-42 and am on a job with some hills. And the weather is warm, and thus the brakes are chattering a little. I had changed the axle oils last year with jcb brand oil. Is there an additive I can add to stop the chatter?
We use ford friction modifier in most of our axles. It helps keep brake chatter down a lot especially in the old skytraks. I would thing one brand is good as the next.. We just use the motorcraft due to the fact everyone carries it.
I see it comes in 4oz bottles. How much would you add to each axle?
How about this cat axle oil additive? Says it is specifically for brake chatter on backhoes. https://parts.cat.com/en/altorferindustries/197-0017
The Cat addiitve might work depending on what oil the axle has in it now.
Jcb gear oil plus - high performance
That's a GL-4 Gear oil. I know the Cat additive will work with TO-4 but I have no idea if it is compatible with gear oils. Maybe someone else might know.
Called Local cat dealer and he says he can't get the additive for at least a month. I guess there's a shortage. I'll have to search wear else I can find.
You can get the cat stuff from jlg/genie/skytrac/amazon/ xyz. If you pull up the msds aside from the cat bottle its the same as almost all limited slip addatives in its product range.
I swung by O'Reilly tonight. Bought 8 bottles of the Ford friction modifier. $5 bottle. I figure I'll put 4 bottles in each axle. I think the axle takes almost 4 gallons of gear oil.
Did that work?
It did!
