An adjusting washer is a precisely dimensioned flat component used to set or fine-tune the spacing and alignment between mechanical parts within an assembly. In equipment like the HIF 690 Flameless Air Heater, it ensures that moving or fastened components sit at the correct depth and angle, preventing excessive play, uneven wear, or improper load transfer. When an adjusting washer wears thin, becomes distorted, or goes missing, surrounding components can shift out of alignment, leading to accelerated wear, vibration, or loss of correct mechanical function.
