Product description
Connecting rod bearing shell for tractors and mini tractors of the LS Tractor brand, LS i, J, R series and others.
Connecting rod bearing shells are components whose main task is to reduce friction at the joint between the connecting rod and the crankshaft. The shells are two separate, semicircular elements that form a circle once fitted. Bearing shells (although not all types) also have a small groove or notch through which the lubricant is distributed. The most common reasons for rapid wear of connecting rod bearing shells are:
- use of oil with unsuitable viscosity parameters,
- incorrect installation of the bearing shells,
- failure to observe oil change intervals,
- low engine oil level,
- overloading the engine before it has reached the correct temperature,
ITEM NO. 4 MARKED IN BLUE ON THE DIAGRAM.
Compatible with 40055361. Previous part number: 30A1900040.
LS Tractor:
- LS i28, i36,
- LS J23 (HST), J27 (HST),
- LS R28i, R38i,
The first signs of connecting rod bearing wear are an unnatural, steady knocking coming from the engine. Worn bearing shells must be replaced with new ones as soon as possible; replacing the faulty part too late may cause serious damage to the shaft, connecting rod or engine.

Questions & Answers
Why is regular filter replacement (oil, air, fuel) crucial for a mini tractor?
User
Regular filter replacement is the easiest way to extend the life of an engine from brands like Kubota or Yanmar. The oil filter removes metallic contaminants generated during operation, the air filter protects the cylinders from field dust, and the fuel filter prevents water and dirt from damaging the precision injection system. We recommend replacing filters every 50-100 operating hours or at least once per season to ensure optimal engine performance.
How to properly select and sharpen mower blades for a Japanese tractor?
User
When selecting mower blades, consider the mower deck model and the blade length and center bore diameter. Maintaining blade balance is crucial when sharpening – an unbalanced blade causes vibrations that damage the hub bearings. Remember that sharp blades mean healthier grass, a cleaner cut, and less strain on the engine of your Iseki or Mitsubishi tractor.
How to identify the correct V-belt size and how to care for it?
User
It's best to read the markings on the side of the old V-belt. If they are illegible, measure the belt width and its outer length (La). On Shibaura and Hinomoto tractors, it's important to regularly check the belt tension – too loose a belt will cause slippage and faster wear, while too tight a belt can cause alternator or water pump bearing failure.
