HM380 breaker cylinder bolt 580 mm 332/A2452 JCB, aftermarket

HM380 breaker cylinder bolt 580 mm 332/A2452 is an aftermarket part for the JCB hydraulic breakers. According to the product card, this part is a breaker cylinder bolt for the HM380 breaker.

The front head, cylinder and back head of a breaker are held together by long through bolts (side rods), and the side plates and housing are fixed with separate bolts. These bolts take heavy tensile loads with every blow. A loose through bolt lets the body parts move, causes oil leaks and finally breaks. The torque of the through bolts is therefore checked regularly.
