When installing a master link in a roller chain, the closed end of the master link clip goes toward the direction the chain will be moving.
On a combine, most belts, pulleys, chains and sprockets turn in the same direction as the wheels on that side of the machine. That means things on the left side of the machine generally turn in a counter-clockwise direction, and things on the right side of the machine tend to turn in a clockwise direction.
The idler or tensioner on a chain or belt always runs against the “slack” side, not against the side on which actually transmits power between sprockets or pulleys.
A 15/16-inch wrench is a match to a 24-millimeter wrench, just like a 5/8-inch wrench is a twin to a 16-millimeter wrench. Unlike 1/2-inch and 13-millimeter, or 3/4-inch and 18-millimeter wrenches, which are evil twins of each other.
Most types of Loctite or other thread-locking products liquify when heated, so heated a Loctited-nut or bolt while turning it with a wrench or socket will often loosen a “glued” fastener.
