If you have a "ticking" noise at idle, on your newer four-stroke, you need this part.
The 2008 and newer 4-stroke KTMs (and some earlier SX models) use a timing chain tensioner intended to develop its force using the engine oil pressure. The O.E.M. tensioner has serious flaws which can leave the timing chain in a slack condition, possibly causing serious engine damage. Dirt Tricks has developed a simple, effective and failsafe replacement. The Dirt Tricks Timing Chain Tensioner uses oil pressure combined with a mechanical ratchet system to prevent collapse and avoid issues caused by a slack timing chain on the new 4-stroke motors. The replacement unit will work on all newer four-strokes in 250, 400, 450, 505, 530 models using the RC4, XC4, or RF4 motor (not for the RFS motors).
- Can be installed in less than five minutes.
- Resolves issues with a slack timing chain on the new 4-stroke motors.
- Uses oil pressure combined with a mechanical ratchet system to prevent collapse.
Detailed Specifications:
- Replaces KTM part# 77036003000 and 77036003100.
- For the RC4, XC4, RF4 2008-2010 motors (250, 400, 450, 505, 530, all models).
- Also fits 2009-2010 Husaberg 390,450, and 570; Husaberg installation requires special instruction (Tensioner must be installed collapsed. This requires laying your bike on its side to install).
