Flex PlateThis flexible plate is an aftermarket replacement, contact us to verify fit. Flex plates connect the engine crankshaft to the torque converter on IC forklifts, transmitting torque while accommodating slight axial movement. Cracked or warped flex plates show up as vibration at idle, hard starts, and eventually a sheared plate that strands the truck. Rebuild shops inspect them whenever the transmission comes out and replace at the first sign of stress cracks. Confirm your engine and converter combination, plus the bolt circle, and we can verify AC3EB-13-12331L matches before shipping.Aftermarket replacement part, cross-references original part number AC3EB-13-12331L.Need help confirming fit?
