ABSTRACT:
An earth mover scraper combination having chain driven elevator drive sprockets for each of two chains which are mounted on plates that include pins extending into the frame of the elevator support. Two jacks are likewise inserted into the frame of the elevator support and can be used to force the pins away from the frame support thereby forcing the sprocket away from the frame support and tensioning the chain. Preferably, the jack is a hydraulic jack that can be operated with a simple grease gun. Metal shims are then placed between the mounting bracket and the frame assembly to maintain the chain tension.
