Product: Large, Heavy Crawler Sprockets-Split Version
Cogmatic has made very large, heavy crawler sprockets for one of our customers for years. These parts have an unusually large bore and the customer always wanted the part in one piece to avoid distortion. They were also concerned that the rather thin cross section might shift slightly under load, experiencing greater wear at the split line. Having the sprockets made in one piece meant that changing out a worn out chain and sprocket required a significant tear down of the machine since the hydrostatic drive unit had to be removed in order to remove the sprocket. That was very unpopular with their customers.
Cogmatic manufactured and continues to provide the customer with split versions of the sprocket for field testing. Units are in the field now showing no difference in wear and promising a much easier change out for our customer’s customers when it is time to change the parts over.
