  • What are Oil Seals and how should they be ordered?

  • The importance of small oil seals cannot be understated. They are the guardians of lubrication, ensuring that oil does not escape from bearings or other moving parts. Without these seals, friction would increase, leading to premature wear and tear of components. Moreover, oil leaks can pose significant environmental risks, contaminating soil and water sources if not contained. In high-performance applications such as aircraft or racing vehicles, the failure of an oil seal can have catastrophic consequences, highlighting the critical nature of their role In high-performance applications such as aircraft or racing vehicles, the failure of an oil seal can have catastrophic consequences, highlighting the critical nature of their role In high-performance applications such as aircraft or racing vehicles, the failure of an oil seal can have catastrophic consequences, highlighting the critical nature of their role In high-performance applications such as aircraft or racing vehicles, the failure of an oil seal can have catastrophic consequences, highlighting the critical nature of their rolesmall oil seals.
  • An oil seal is a simple yet sophisticated device, designed to prevent the ingress of contaminants and the egress of lubricants. It consists primarily of a rubber part, which is the sealing element, along with metal casings or springs that provide the necessary compression to maintain the seal. The rubber component, often manufactured from materials like NBR (Nitrile Butadiene Rubber), FKM (Fluoroelastomer), or HNBR (Hydrogenated Nitrile Butadiene Rubber), is chosen based on its compatibility with the operating conditions and the fluid it will be in contact with.

  • To do this, turn the engine with a socket on the crankshaft pulley bolt until the rotor arm is pointing to the plug contact of the timing cylinder (usually No. 1, check in the car service manual), and the timing marks on or behind the pulley show exactly top dead centre ( TDC ).

  • Like any other small engine, your snowblower relies on a spark plug to ignite the fuel mixture in the combustion chamber. Without a properly functioning spark plug, your snowblower won't start or run efficiently. That's why it's essential to check and replace your snowblower's spark plug regularly to keep your machine in top working condition.
