TYPE-TRACK TRACTORS (BULL-DOZER) PRE-INSPECTION
Machinery pre-inspections are vital. They help avoid costly downtime, repairs, and most importantly-ensure safety. One of our lead Service Technicians-Mason Sydow -showcases the basic steps involved in a pre-inspection.
Inspecting Your Dozer
Prior to performing any inspection-making sure all of the safety protocols are followed is step one. Refer to your machine’s Operation and Maintenance Manual (OMM) to make sure the necessary safety precautions have been done.
Walk the perimeter of the machine and look for signs of oil on the ground. Look beneath the bottom of the machine as well. Check track tension and inspect under carriage for signs of rubbing and excessive wear.
Make sure to check all fluid levels before starting machine. You’ll want to check your final drive oil level. They need to be lined up. This is also explained more thoroughly in the OMM. Check track tension for a slight droop over the front idler, to the carrier roller, and then to the sprocket segments.
Check hydraulic cylinders on both sides of the machine. Make sure there are no leaks coming out of the seals. Check the fluid lines, angle cylinder, lift cylinder. Make sure fluid lines are good and not leaking.
Check the cutting edge and make sure there is no missing hardware and there is enough life left in the cutting edge.
Check hydraulic oil level and make sure the hydraulic fill cap and fuel cap are in place.
Step back and look under the machine for any signs of hydraulic leaks. Check both duo cone seals for the final drives and make sure they’re not leaking. Walk the perimeter of the machine and look for signs of oil on the ground. Look beneath the bottom of the machine as well.
Additional inspections that should routinely be checked before turning on the machine are checking the oil, checking the coolant levels, and testing the back up alarm and horn. Also, make sure the entire machine is greased daily or every 10 operating hours .
