Excessive chain pitch elongation is caused by pin and bush wear — once elongation exceeds OEM replacement limits, the chain rides high on sprocket teeth and accelerates sprocket wear significantly. This aftermarket track bush pc40-8 for the PC40-8 is manufactured to OEM dimensions for a direct replacement that restores correct pitch and pin/bush clearance.

Why Choose This Track Bush PC40-8
– Pin diameter: OEM ±0.01mm for correct link bore press-fit
– Bush bore: OEM running clearance on pin for designed seal life (in SAL chains)
– Component length: OEM for correct chain assembly width

Heavy-Duty Construction
This track bush pc40-8 is manufactured using alloy steel pins: surface case-hardened to OEM hardness for wear resistance. Through-hardened bushes for consistent wear resistance across full operating depth. Precision-ground surfaces for dimensional accuracy. Designed to withstand vibration, impact loads, and harsh operating environments commonly found in construction, quarry, mining, and earthmoving applications. Precision manufacturing helps ensure correct fitment and long service life.

Applications
Suitable for a wide range of heavy equipment and undercarriage systems including:
– Excavators
– Dozers
– Loaders
– Track roller assemblies
– Earthmoving machinery undercarriage components

Maintenance Recommendations
– Replace as a matched set
– Assess chain links for elongation and cracking before deciding between partial and full chain replacement
– Replace sprocket simultaneously where tooth wear is evident
