Apparatus, systems, and/or methods for adjusting belt tension in a material removal machine are disclosed. In some examples, the material removal machine includes a material removal tool secured on a spindle. A spindle pulley may be secured to the spindle, such that rotation of the spindle pulley causes the material removal tool to be rotated via the spindle. The material removal machine may further include a movable hub that retains the spindle, such that movement of the hub translated into movement of the spindle. Because the spindle pulley is securely attached to the spindle, movement of the hub may translate into movement of the spindle pulley. This movement of the spindle pulley may change a distance between the spindle pulley and an actuator pulley, thereby changing the tension in a belt connecting the spindle pulley and the actuator pulley.

A pulley stopper including: a clamp portion that includes a bar-shaped upper clamp and a bar-shaped lower clamp; and a pair of fasteners that are disposed at opposite ends of the clamp portion to couple the upper clamp and the lower clamp. The pair of fasteners and the clamp portion are coupled such that the upper clamp and the lower clamp are fixed side by side through the coupling of the fastener and the movement of a belt disposed between the upper clamp and the lower clamp is stopped.

A structure for belt installation of an engine for a vehicle is provided. The structure includes a damper pulley that is mounted to a crankshaft of the engine and a stretch belt that has a first end mounted on the damper pulley and a second end connected to an upper portion of a pulley portion of an accessory. The accessory is mounted on the engine at a position spaced apart from the damper pulley. The pulley portion includes a guide member on a front center thereof which guides installation of the stretch belt to the pulley portion.

A belt pulling tool is comprised of a handle, a body and two prongs, the handle and body each having two ends with one end of each being attached to the other forming a longitudinal length and the two prongs being attached to the body orthogonal to the length, wherein at least one prong is configured to be moved and fixed along a portion of the length of the body. The belt pulling tool is useful for aligning, seating and setting the tension of belts for industrially belt driven machinery. In performing the method, the belt is inserted between the gap between the prongs of the tool and the tool is rotated about an axis centered in the gap and running parallel to the prongs projecting from the body of the tool to engage the belt and cause the rotation of the sheaves, thus allowing the sheaves to be aligned using alignment tools and allowing the belt to properly seat. Once seated and aligned, the tension may be set using a belt tension gauge.
