INDUCTION HARDENING

JP Engineering induction hardens all crank sprockets for all chain sets, crank gears for

full steel timing gear sets and oil pump drive gears.

Induction hardening is used to improve tooth life of your gears and sprockets, as well

as pre-work harden gears and sprockets before they are installed onto engines.

WHAT IS INDUCTION HARDENING?

Induction hardening is a process where steel is hardened by means of induction

heating and a subsequent quenching of water.

WHY INDUCTION HARDEN?

The advantages of induction hardening gear and sprocket teeth include:

  • 1. To localise hardening of tooth surfaces where the hardness is needed. Unlike
  • 2. Hardened teeth are pre-work hardened. The process of induction hardening
  • 3. The speed of hardening is a rapid process. It takes approximately 30 seconds
  • 4. The use of computers makes it easy to control the depth of hardness

HOW DOES IT WORK?

The part to be hardened is placed inside an “Applicator” coil, through which an alternating current is then passed.

This coil is round as we use it for gears and sprockets and is usually made of copper tubing which has water passing through it to prevent overheating.

Multiple pieces are placed onto the rod which rotates, heating the parts and then feeding the rod downward into the quench water.

Oil Pump Information

JP Performance Oil Pumps are manufactured to the highest quality.

Manufactured from cast iron on CNC equipment, every pump is bench tested before packing to ensure they are working correctly and to guarantee quality and longevity.

Just ask racers... they rely on these oil pumps to keep their engines running.

Myths about High Volume Oil Pumps

High volume oil pumps are best used when an engine reaches higher RPM. This is usually above 4500RPM.

At this point the ability of a standard oil pump to adequately feed the connecting rod bearing is strained.

A high volume oil pump will solve oil starvation problems above this rev range.

What high volume oil pumps will not do is:

  • 1. It will not replace a rebuild, in a worn-out engine.
  • 2.It will not pump the oil pan dry. Both solid and hydraulic lifters have metering valves to limit flow of oil to the top of the engine. If a pan is pumped dry, it is because the holes that drain back the oil are congested.
  • 3. It will not wear out distributor gears. The load on the gear is directly related to the resistance to flow. Distributor gear failures are usually caused by a worn out gear on a new cam gear, incorrect gear angles and/or worn bearings causing misalignment.
  • 4.It will not cause foaming of the oil. With any oil pump, the excess oil not needed by the engine is recirculated within the pump. Any additional foaming is usually created by revving the engine higher. The oil thrown from the rod bearings is going faster and causes the foaming. This is why high performance engines use a Windage tray.
