E-kits provide increased capacity and extended lubrication intervals with a lube cycle of 50 – 250 hours. This is achieved by providing an improved seal and roller bearings design, which results in a longer life cycle. E-Kits are interchangeable with other cross and bearing kits in Weasler series as well as standard cross and bearing sets in the market. This means that a Weasler PTO drive shaft with E-kits can still be upgraded to M-kits.
