2 Stroke Connecting Rod Failure

It converts the linear motion of the pistons to the rotary motion of the crankshaft.

2 stroke connecting rod failure. The following proper maintenance can minimize bolt failure. The bolt is given a good surface finish to reduce stress raisers. Either way the engine is going to need a new rod. As the crankshaft turns the rod also turns forcing the piston up and down.

The ends of the rod spin around the crankshaft and the wrist pin of the piston. The connecting rod is fastened around the crankshaft on one end and to the piston on the other end. Connecting rod with its parts minimizing the failure of connecting rod bolts by proper maintenance. Fatigue near a physical defect on the rod from the failure of the rod bolts from a defect improper tightening lubrication failure in bearing.

The connecting rod connects the pistons to the crankshaft. The broken rod can go through the. This video will show how to rebuild a two stroke crankshaft. On every stroke the connecting rod is stretched and compressed.

Bolt surface and threads must not be damaged by rough handling. This is video to remove crankshaft bearing without hammer https youtu be zb9sqod9blg check this video installation connecting rod kit without hummer https. A bad rod or rod bearing will eventually destroy an engine. Two from k l and one from ktm.

We will be highlighting three special tools. I can t think of one ever built with a pressure fed big end. Cast rods are more brittle than forged or billet rods and will often break when this happens. A connecting rod also called a con rod is the part of a piston engine which connects the piston to the crankshaft together with the crank the connecting rod converts the reciprocating motion of the piston into the rotation of the crankshaft.

Forged and billet rods are more ductile and will usually bend or buckle rather than break. Some two stroke engines are designed with the transmission side main bearing on the outboard side of the main seal so that it s oiled by gearbox lube but otherwise the rod big end is oiled by the fuel oil mix. Another common cause of rod failure is a bearing seizure.
