Loader operators hampered by constant greasing and parts-laden auto-lube systems now have a solution with NeverGrease pin joints, available for John Deere’s 544K through 844K four-wheel-drive loaders.
NeverGrease pin joints are sealed and lubricated for life, eliminating daily greasing. They’re designed for all the joints in the boom, linkage and bucket.
“With NeverGrease pins there is a cost savings on grease and a time savings for operators every morning,” said David O’Keeffe, product marketing manager, John Deere Construction & Forestry Company. “They also lead to longer pin life, which means greater uptime and lower loader maintenance costs.”
Operators will no longer have to locate and prepare grease guns or refill and manage auto-lube systems and their pump, valves and plumbing — which require constant inspection of their own.
NeverGrease pins not only eliminate grease fittings but they also ensure that pin life is consistent from joint to joint, since there’s no risk of infrequent or poor greasing. Because the pins last longer, there’s less rebuilding of pin joints.
There’s also reduced maintenance because the roller bearing elements used inside the boom-to-bucket joints and the bushings in the remainder of the machine’s joints are pressed in, eliminating welding and line boring during rebuilds. Both systems include sealing that keeps debris out of the respective joints.
“And loaders stay cleaner because there isn’t as much grease around to hold dirt,” O’Keeffe said. “The lack of grease makes machines faster to wash, easier to inspect and easier to repair. Leaks are easier to spot, and a technician doesn’t have to remove the grease from the cylinder just to replace a hose. Job sites with less grease are more environmentally friendly, too.”
Boom-to-bucket pin joints use a roller-bearing element with a series of barrel-shaped roller bearings to improve load distribution. Other boom and linkage joints use a filament-wound Teflon bushing for grease-free lubrication.
