Corrosion Resistance: Many pins have a surface treatment or coating, such as a phosphate coating or black oxide finish. This provides a base layer of corrosion resistance and helps retain lubrication.
Lubrication Channels: Most pins on the 336D feature drilled passages (zerk grease fittings) that allow pressurized grease to be pumped between the pin and the bushing. This creates a lubricating film, reducing friction and wear, and also helps to purge contaminants.
This 526-0603 pin is used for 336D 340D 336D2 340D2 336 336GC excavator.
