Spool is the Atlas Copco service part carried under part number 3371814112. Cycle timing runs through this component. Because it shuttles on every blow, it accumulates cycles faster than almost anything else in the hammer.
You will find it on the diagram for the LH11 Hydraulic Pick Hammer and LPD-LD Hydraulic Post Driver, and on 7 other machines. Check it against the reference number on the diagram first; serial breaks change what fits.
Everything else on that machine is one page away on the parts diagram library; complete tools are on the Atlas Copco catalog. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
