Servicing a McCormick MC 115 starts with the right part. You will find more than 40 matching items here, among them trailer couplings, electrics and lighting.
This page carries more than 40 McCormick MC 115 parts from Walterscheid, GRANIT, MAHLE, ROCKINGER and Scharmüller. Between them they cover the routine service, the cooling system and starting, and the hitch at the back.
For servicing there are air filters with their inner element and engine oil filters. On the cooling side you will find the water pump and its gasket, and for the cab, air conditioning compressors.
When replacing the water pump, always fit it with a new gasket on a clean, flat face, and skip any extra sealant that could break loose inside the cooling system. Turn the new pump by hand before fitting the belt, check the belt for cracks and set the correct tension. Moisture at the small weep hole at the bottom of the pump housing is usually the first sign that the shaft seal of the old pump is going.
Do not blow out an air filter with compressed air at close range, as that tears the paper and lets dust into the engine. The inner element normally stays in place at a regular service and is changed less often than the outer one.
For towing there are flange hitches, drawbars with ball, a ball hitch, a top drawbar and Piton Fix. Measure the rail width and the locking pin on the MC 115 before choosing, since both have to match the new coupling.
The MC 115 can take two kinds of starter: a standard starter motor or a gear reduction starter. A reduction starter works through an intermediate gear and usually has more torque in hand on a cold engine. Which one you choose depends on what is fitted now and the space around the mounting, so compare the shape and the number of teeth with the old unit. For an aircon compressor, check the number of pulley grooves and the line connections. If the old compressor seized, flush the system and renew the receiver drier before fitting the new one.
Model and serial number are on the tractor's type plate. For filters and starters, the number on the old part is the easiest check, printed on a filter's casing or on a starter's plate or housing.
There are no separate sister models of the MC 115 with their own page here. Other McCormick tractors, small and large, are listed under McCormick parts.
