Connecting rod bearings / STD + 0.50 mm / Kubota M7040 / Kubota V3307

Connecting rod bearings of standard size + 0.50 mm (so-called second-grind bearings) 020, i.e. 22.75 mm wide, 1.60 mm thick and with an outer diameter after assembling of approximately 54 mm, for Japanese tractors and mini tractors of the Kubota M7 series with a Kubota V3307 engine and others .

Connecting rod bearings are elements whose main task is to reduce friction at the point of connection of the connecting rod to the crankshaft. The bearings are two separable, semicircular elements that, when installed, create a circle. The bearings also have a small groove or cut through which the lubricant is distributed. The most common reasons for rapid wear of connecting rod bearings are:

• using oil with incorrect viscosity parameters,
• incorrect installation of bearing shells,
• failure to comply with oil change intervals,
• low engine oil level,
• overloading the engine, which has not reached the correct temperature,

Dimensions :

• width: 22.75 mm,
• thickness: 1.60 mm,
• diameter: 54 mm.

Tractor models :

• Kubota M7040,

Engine models :

• Kubota V3307.

The first signs of wear of connecting rod bearings are an unnatural, steady knocking coming from the engine. Worn bearings must be replaced with new ones as soon as possible, replacing the faulty element too late can cause serious damage to the shaft, connecting rod or engine.
