Green cylinders from two industries, one measurement standard

Construction Deere cylinders arrive with impact written on them: rods nicked by rock, barrels dented, eye bushings hammered oval by shock loads the seals were never meant to absorb. Agricultural Deere cylinders fail slower - chrome thinned by seasons of dust, hitch cylinders bypassing internally, steering cylinders wandering as gland clearance grows. Both get the same discipline on our bench. We measure bore size and finish through the full stroke, rod diameter, straightness and chrome condition, gland and piston clearances, and eye and bushing wear, then build the quote from that record: honing, re-chroming, new rods or barrels machined in-house, bushings and pins renewed, and a complete seal package matched to the cylinder's pressure class. The result is a Deere cylinder that holds a grade, lifts without creep and stops painting the jobsite with oil. Large-bore Deere cylinders are broken down on a dedicated bench with the barrel supported through its length, and every internal part is laid out in stroke order so wear bands can be read like a map of where the cylinder actually worked hardest. Tie-rod and threaded-head constructions each get their correct assembly torques, lock systems are renewed rather than reused, and rod coatings are matched to duty - a scraper or dozer cylinder that lives in abrasive dust leaves with its wiper and rod protection reviewed, because the finest internal rebuild still dies early behind a torn boot and an indifferent wiper ring.
