Model 8202-290A Torque Multiplier
WARNINGS
•
Do not exceed rated output of tool
•
Outputs turn in opposite directions. Verify direction before applying torque
•
Do not hold multiplier while applying torque. Normal multiplier deflection may pinch
fingers, especially in confined locations.
•
Maintain firm hand control of torque wrench or input handle when releasing multiplier
because recoil (wind-up) will be experienced.
•
Remove input handle when not applying torque.

1. INSTRUCTIONS
1.1 The model 8202-290A Torque Multiplier is a geared wrench
designed for use in conjunction with model 8200, 8300, 8111 or
8112 Torque Multiplier. The 8202-290A Torque Multiplier has a
torque ratio of 6.5:1 and a maximum output of 1,200 ft-lbs
torque. It has a 1/2” square female input and two 3/4” male
output drives.
1.2 The model 8202-290A Torque Multiplier has 360° continuous
rotation in either clockwise or counter clockwise direction. An
integral, two-directional input torque holding device inhibits
accidental torque wind-up release. The torque multiplier has two
output drives. One turns at 6.5:1 (1/6.5 the speed of the input
wrench) to provide a high torque for torque breakaway. The
other output turns at 1:1 (the same speed as the input wrench)
to provide rapid tightening and loosening of fasteners
1.3 A positioner controls rotational direction for manually applied
input.
2. PROCEDURE
2.1 Select the proper anchor plate and socket to be used with the
attached torque multiplier (model 8200, 8300, 8111 or 8112).
2.2 Mount the anchor plate, socket and torque multiplier in proper
position for the specific application.
2.3 To tighten: Mount the 8202-290A on the model 8200, 8300,
8111 or 8112 Torque Multiplier. Engage the appropriate 3/4”
male output drive of the 8202-290A Torque Multiplier (1:1 or
6.5:1 ratio drive) with the 3/4” female input drive of model 8200,
8300, 8111 or 8112 Torque Multiplier. The anchor plates of the
8202-290A Torque Multiplier will extend over the edge of the
attached torque multiplier. Rotation of the input square drive
may be required in order to match mating multiplier’s square
drive.
2.4 Rotate the positioner ring to the tighten position. Input and
output rotation directions are the same for the 1:1 drive.
(EXAMPLE: Input clockwise = output clockwise) Input and
output rotation directions are opposite for the 6.5:1 drive.
(EXAMPLE: Input clockwise = output counter-clockwise).
(See WARNING).

8-REQD
2.5 Mount a suitable ratchet adapter and/or torque wrench to the
input of the 8202-290A Torque Multiplier and apply the load in a
counter-clockwise direction.
Note: See Torque Conversion Chart (item 3.2). This chart
shows the amount of input torque required to produce a given
output torque on the 8202-290A Torque Multiplier.
2.6 Torque output accuracy requires the use of an accurate torque
wrench in series with the torque multiplier. Apply torque with
torque wrench until desired input torque is achieved. To remove
multiplier from fastener, apply enough input torque to release
integral torque holding device, then turn positioner into opposite
position. (EXAMPLE: Rotate the positioner in CW positions for
tightening. Apply input torque in the CW direction to relieve
internal force. While holding input torque in the CW direction,
rotate positioner in the CCW direction for release) and slowly
relax input torque.
To Loosen: Follow same procedures for tightening except
set positioner in opposite position. (EXAMPLE: If fastener
requires clockwise tightening rotation, rotate the positioner
in counter-clockwise position for loosening).

4. GENERAL NOTES
Do not use impact tool on torque multiplier.
Torque reaction creates a rotational force in the opposite direction
from which input force is applied.
The output torque is the torque ratio times the input.
Use only Sweeney approved replacement parts.
