P2	TorqueMaster® Spring Removal
Tools Needed:	A TorqueMaster® spring system can be
	identified by the end brackets. For single
Recommended	spring applications, the right hand end
	bracket will always have a drive gear,
tools from	counter gear, counter cover, and a winding
page 5	bolt head. The left hand end bracket will
	have no gears, counter cover, or winding
	bolt head. The hole for the winding bolt
	head will be plugged.
	For double springs, both the right hand
	and left hand end brackets will always
	have a drive gear, counter gear, counter
	cover and a winding bolt head.
	IMPORTANT: Right and left hand is
	always determined from inside the
	building looking out.
	Step 1: If you have a black counter cover:
	Place a mark on the drive gear tooth and an
	adjacent mark on the right hand end bracket
	(Fig. 1). Loosen the lock nut 1/4 turn using a
	7/16” wrench and continue with Step 2.
	If you have a gray counter cover: Loosen
	the lock nut 1/4 turn using a 7/16” wrench
	and continue with Step 2.
	Step 2: Using an electric drill (High
	torque / gear reduced to 1300 rpm
	preferred) with a 7/16” hex head driver,
	unwind the right hand winding bolt head
	counterclockwise (Fig. 2) and count the
	number of turns the mark on the drive
	gear passes the adjacent mark on the end
	bracket. Referencing the chart below, by
	door height, stop unwinding the spring
	once the counted turns have reached the
	listed number of turns.
	6’-0” Door Height = 14 turns
	6’-3” Door Height = 14 1/2 turns
	6’-5” Door Height = 15 turns
	6’-6” Door Height = 15 turns
	6’-8” Door Height = 15 1/2 turns
	6’-9” Door Height = 15 1/2 turns
	7’-0” Door Height = 16 turns
	7’-3” Door Height = 16 1/2 turns
	7’-6” Door Height = 17 turns
	7’-9” Door Height = 17 1/2 turns
	8’-0” Door Height = 18 turns
