Upper Roller Removal and Installation of Upper Roller ・ When loosening the check valve, loosen it a little at a time and stop when any grease appears. (The pressure inside the cylinder is very high, so there is the danger of grease Warning being expelled and the plug flying off if the check valve is loosened too much.) The check valve adjustment procedure should not be done in front of the check valve. Caution ・ Be sure to stop the engine before beginning work.
Items to prepare • Box wrenches (19 mm, 30 mm) • Jack (That meets the lifting weight.) • Rag • Cleaning fluid • Wood planks, etc. [1] Use a box wrench (19 mm) to loosen the grease cylinder check valve (1), then loosen the shoe tension.
