Running a Case IH 685 XL, also known as the IHC 685 XL? Browse more than 200 matching parts, including lighting, steering and classic tractor parts.
Plenty of people still call this tractor the IHC 685 XL. It is the same machine, so either name brings you to the right parts. Keeping one working today comes down to maintenance: an engine that needs an overhaul after years of work, steering with play in it, a cab door whose gas struts have given up. This page lists more than 200 parts for the Case IH 685 XL, from GRANIT, HELLA, LuK, KS and ZF.
For an overhaul there are piston and liner sets, piston ring sets, gaskets, O-rings and sealing rings. You also get the small items that only show up once the engine is apart, such as the thermostat housing gasket or the O-ring on the feed pump. Radiator hoses, including the bypass hose, seal the cooling circuit back up.
A habit worth adopting: as you strip the engine, lay every old gasket and ring out in order on the bench. You can see at a glance what needs replacing, and nothing gets missed when the new set arrives. Wipe O-rings with a little clean engine oil before fitting so they do not roll or tear as they go in.
Ball joints are a known wear point on a tractor of this age. You feel it as play at the wheel and see it in a split dust boot. There are also clutch plates and lifting spindles for the three-point linkage. Clean the thread of a lifting spindle properly and grease it before adjusting, or it will be seized after one winter outside.
In and around the cab of the 685 XL it is the small, daily-use parts that wear: gas struts for the door, lenses for the indicator and position lights, reflectors and rocker switches on the dash. Flasher units and relays look after the indicators. If the indicators suddenly flash twice as fast, the cause is nearly always a blown bulb or a poor earth rather than the flasher unit, so check those first.
The type plate gives the model and serial number. Many castings, gaskets and hoses also carry a factory reference number. Write it down before the old part goes in the scrap bin, as it is the fastest route to the correct replacement.
The 685 XL belongs to the 85 series from IHC and Case IH. The other models in that range each have their own page with the parts that apply to them: the Case IH 485, the Case IH 585 and Case IH 585 XL, the Case IH 685 and the Case IH 885. The full brand overview is at Case IH parts.
