Refuse-duty cylinders rebuilt for corrosive, high-cycle work

A Garrison packer cylinder usually tells on itself at the rod: chrome eaten by leachate at the retracted position, scoring that shreds the wiper on every stroke, and seals swollen by oil that has cooked through thousands of compaction cycles. Ejector cylinders add their own signature - barrel wear bellied at mid-stroke where the load rides longest. We strip each cylinder and measure bore taper and ovality, rod chrome and diameter at several stations, gland fit and piston condition, then quote the repair those numbers demand: barrel honing or replacement tube, rod re-chrome or a new rod machined and hard-chromed on site, glands renewed, and seal materials chosen to suit refuse service rather than whatever came cheapest in a kit. Root cause is reported too, because a cylinder killed by filthy oil will kill its replacement the same way. Because refuse cylinders cycle under load spikes that standard industrial cylinders never see, we pay particular attention to cushion condition, port welds and the barrel's mounting saddle or trunnion, where fatigue cracks begin quietly beside the weld toe. Dye-checking suspect welds and measuring tube wall where corrosion has thinned it are part of the quote conversation, and a cylinder whose structure is genuinely compromised is condemned in writing - a fleet is better served by that honesty than by a reseal wrapped around a barrel that should not carry pressure again.
