?? Tip in Michel (the corner of the expert)

* "Hi mechanical enthusiasts! The HK 2012 needle socket is the small discreet bearing of the clutch that takes a huge radial load at each clutch. If it takes from the game or heats dry, it's all the gorgeon that starts Vibrate and who uses the box tree !

My stand trick for replacing the HK 2012 bushing: removing it in the axis and the oil bath at assembly !

When changing this bearing, never use a live hammer on the sleeve! The steel outdoor sleeve of the 2012 HK is very fine: if you type through, you will deform it and block the needles inside. Use a suitable roller or a socket at the right diameter that presses only on the rectified outer edge.

Before replacing the bell or pinion over, generously soak the needles of the new HK new with your 2T competition box oil. A well lubricated needle bearing from the first start, it's the assurance of an ultra-silent transmission and a perfect free movement! "*
