What undercarriage spare parts should I keep in stock for my fleet?

Expert_Answer

Stock what stops a machine, not what wears predictably. Wear parts — chains, shoes, rollers, idlers, sprockets — are measurable, so plan them via inspections instead of shelving capital. Keep on hand: track shoe bolts and nuts (a handful of loose bolts causes torn threads and cracked shoes), master pins or links for the chains in your fleet, one spare bottom roller per common machine class (a seized roller can be swapped in the field in an hour), track adjuster seal kits and grease fittings, and for rubber-tracked machines one spare track per common size if downtime is expensive. Standardising the fleet on fewer undercarriage configurations shrinks the stock list dramatically — worth considering at machine purchase time.
