The Optibelt 4T 2.5/177 is a T2.5 profile timing belt with a 177 mm length and a 2.5 mm pitch, part of the Alpha Torque / Alpha Power series. Before fitting it, inspect the drive and sheaves so the new belt runs true and wears evenly. We carry this belt for maintenance, engineering and purchasing teams across the US, Canada, Mexico and South America.

Start the job by checking the sheaves for wear, debris or damage that could affect belt seating. Confirm the pulley grooves match the T2.5 profile and that the 2.5 mm pitch aligns with the drive design. Any misalignment or worn sheave should be corrected before the belt is installed, since the belt itself cannot compensate for a poor drive condition.

The 4T 2.5/177 measures 177 mm in length and uses a 2.5 mm pitch. Read the marking on the back of the old belt and compare it with this part number to confirm the replacement matches. If the old belt is worn or the marking is unreadable, measure the drive and check the pulley tooth count against the required pitch and length.
