Detailed Description

Dorman 594-830 is an engine harmonic balancer designed for 1984-1989 Toyota Van applications. It uses a bonded rubber isolator to reduce crankshaft vibration and a ductile steel body to support long-term service in demanding engine environments. The balancer measures 145 mm outside diameter, 29 mm inside diameter, and 49 mm depth, with one mounting hole and degree markings for timing checks. This part cross-references PowerBond by Dayco (e.g., PB1244N) for the same application.

What It Helps Fix

• Excess engine vibration felt through the crankshaft and accessory drive
• Worn or separated harmonic balancer rubber bond
• Timing reference issues when degree markings are no longer readable
• Serpentine belt drive concerns related to a damaged pulley surface
• Noise or imbalance caused by a deteriorated crankshaft damper

Installation Notes

Verify crankshaft fitment, keyway alignment, and pulley groove count before installation. This Dorman 594-830 harmonic balancer is for Toyota Van models from 1984 through 1989 and should be matched to the vehicle’s serpentine belt configuration and mounting dimensions. No center bolt or washer is included.

Quality Assurance

Dorman manufactures this direct replacement balancer with ductile steel construction and a bonded rubber isolator to support vibration control and durability. It is engineered to meet the needs of Toyota Van owners replacing a worn harmonic balancer with an OE-style service part.
