Snap-on TE803FU Torque Wrench, U.S. Follow-up Torqometer, 1″ Drive, 800 ft-lb

Description

Cement plants and stone quarries run crushers, screens and conveyors that slowly work bolts loose. So maintenance crews retorque those joints at each shutdown. The Snap-on TE803FU torque wrench suits that heavy work, with a 1-inch drive, an 800 ft-lb U.S. reading dial and a follow-up needle that holds the peak.

Heavy plant joints in the 800 ft-lb class

• Jaw and cone crusher frame bolts that carry a torque value.
• Conveyor pulley bearing housing and take-up bolts.
• Vibrating screen side plate and motor base bolts.
• Gearbox and coupling guard bolts on kiln and mill drives.

However, liner and anchor bolts often have their own methods. Therefore confirm each value with the equipment maker.

Reading a U.S.-only scale

This model reads in ft-lb only. So when a European drawing quotes N·m, divide that value by 1.356 first. For example, 900 N·m equals about 664 ft-lb. Write the converted value on the job card, so the fitter only needs to watch for that mark.

Snap-on TE803FU torque wrench: the catalog row

• Square drive: 1 inch.
• Scale: 800 ft-lb full scale, with 10 ft-lb marks.
• Overall length: 66-13/16 in, nearly 1.7 m.
• Width: 3-9/16 inches, with a head depth of 2-1/32 inches.
• Extension: 92TQPA 4 ft tubular handle, packed separately.

Snap-on lists these values in the US Reading/Standard 2% Accuracy table of its CAT1500i catalog. At the top mark, the dial equals roughly 1,085 N·m.

Why a held reading helps on a noisy floor

Crusher bays are loud, dusty and tight, and a fitter often pulls from an awkward angle. The follow-up pointer on the TE803FU stays at the highest value. As a result, the fitter can finish the pull safely and then read the dial. So a second person does not have to watch the needle during the stroke.

Grade, band and care for the TE803FU

Snap-on’s brochure defines the Standard 2% grade from 20% of full scale to full scale. Thus, on this wrench, the band starts near 160 ft-lb. Also keep the dial guard clear of crusher dust, and store the wrench flat. In addition, never use it as a breaker bar on seized liner bolts. Then return it to an outside lab for checks at fixed intervals, as the catalog advises.
