Trailer couplings and lighting are the best represented groups in this overview for the Renault 75-34. Altogether there are more than 100 matching parts.
When the engine of a 75-34 comes apart, you want every bearing, bolt and seal on the bench before the first nut is undone. There are more than 100 parts for this Renault from the R series, and a fair number of them belong inside the engine: main bearings, connecting rod bearings, connecting rod bolts and injection nozzles. Around them sit radiator hoses, a hydraulic double pump, ball joints and hitching gear from GRANIT, Walterscheid, GRAMMER, ROCKINGER and Bosch/Rexroth.
Measure the crankshaft journals before ordering bearings. If they are round and within size, a standard bearing will do. If the crank has been reground, the undersize of the new bearing must match the grind. Connecting rod bolts stretch permanently when they are torqued, so they should never be reused. Have a fresh set ready for every rod you take off.
If the tractor starts poorly or smokes black under load, have the injection nozzles pressure tested by a diesel specialist first. The test shows whether opening pressure and spray pattern are still right before you spend anything. Always fit new copper washers when the nozzles go back in. A stop cable and a tube for the pipework complete the engine side.
A simple trick when changing a ball joint: count the turns it takes to unscrew the old joint from the track rod and screw the new one on by the same amount. Toe-in will then be close, which makes the final adjustment much quicker. Clean and lightly grease the threads of the linkage spindles before setting their length, or the adjustment will seize after a season in the dirt.
Many tractors in this range look almost identical, so the type plate is the place to confirm you are working on a 75-34. For bearings and nozzles, the number on the old part is the quickest cross-check against the reference number shown with each product.
Other tractors from the range have their own pages listing only the parts that suit them. See the Renault 75-32, Renault 75-12, Renault 65-32, Renault 70-12, Renault 68-12 and Renault 65-12. For the Renault 681, the 85-34 and every other model of the brand, head to Renault parts.
