Lighting and engine parts are two examples of what is listed for the Renault 75-12: more than 100 parts for this R series model, all on one page.
Blue smoke, rising oil use or a knock on a cold start usually means a Renault 75-12 is due an engine overhaul, and that takes more than a gasket set. This page brings together more than 100 parts for the 75-12, from pistons and bearings to cooling, brakes and the three point linkage.
For the rebuild there are pistons supplied as a complete piston and liner set, connecting rod bearings and main bearings, with KS and GRANIT among the makes. You will also find injection nozzles, gaskets to seal everything up again and a stop cable so the engine shuts down cleanly.
Radiator hoses, including the top hose at the thermostat, go hard and crack with age. A new water pump, tubes and V-belts for the engine cooling, some of them from Optibelt, put the system right.
Bosch/Rexroth and Cobo are represented as well.
Check the type plate on your 75-12 for the type and engine number. On a rebuild, measuring does half the work. Measure the cylinder bores and the crankshaft journals, because those figures decide if you need standard bearings or an undersize. Old pistons and bearing shells usually have a number and size mark stamped in, and that reference number helps you pick the correct replacement.
V-belt tip: a slack belt slips and leaves the water pump turning too slowly, while an overtight belt destroys the bearings in the pump and alternator. Set the tension with a thumb test and check it again after the first few running hours.
With a leaking wheel brake cylinder, a repair kit only makes sense if the bore is smooth. If you see pitting or rust inside, fit a complete new cylinder instead. Bleed the brakes wheel by wheel afterwards, starting with the one furthest from the master cylinder.
The Renault 65-12, Renault 68-12, Renault 70-12, Renault 65-32, Renault 75-32 and Renault 681 each have their own page with the parts that apply to that model. The 77-12 and 85-34 are part of the same range. For the whole make, go to Renault parts.
