The Weasler Tractor Cross and Bearing Kit for Metric BYPY 2 or Walterscheid 2200 Series is standard and offers a high-quality lube cycle of 8 hours which is acceptable for many applications. This tractor cross and bearing kit is interchangeable with other cross and bearing kits in Weasler series as well as with standard cross and bearing sets in the market, meaning that a Weasler PTO drive shaft with P-kits can still be upgraded to E-kits or M-kits. The tractor bearing kit also comes equipped with a blue seal with a grease fitting, making it fast and easy to find a P-Kit.
