Finished the 250-hour service on my XG3037 today and decided to make a few notes:
*All of the WIX filters (oil, inner air, outer air, main fuel, and hydraulic) fit perfectly. The hydraulic filter was slightly shorter than the original but otherwise fit.
*The original inner air filter was very clean even after 250 hours of service....not a speck of dirt or dust. Probably did not need to change it, but did anyway. The outer filter obviously did it's job.
*The oil drain plug required a 17mm socket.
*Had to use a strap wrench on the hydraulic filter..tough spot and large diameter. Will definitely try the vacuum trick the next time....lost about a qt of fluid while changing the filter.
*Did the work in this order; air filters, pre-fuel filter, drained oil, oil filter, filled with oil, main fuel filter, hydraulic filter, all the rest.
*The oil fill location is in a fairly tight area and required the use of a flexible long fill spout on the oil container.
All in all, I was very pleased with it's serviceability and other than the strap wrench and the long flexible fill spout it didn't require any additional tools other than what I normally use to service my truck.
