DIRT TRICKS KTM CAM CHAIN TENSIONER
Replaces KTM part# 77036003000 and 77036003100.
For the RC4, XC4, RF4 2008-2012 motors. (250, 400, 450, 505, 530, all models) Also fits 2009-2012 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)
If you have a "ticking" noise at idle, on your newer four-stroke, you need this part. 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. KTM 350 Unit being developed - CALL FOR AVAILABILITY.
INSTALLS IN 5 MINUTES
The 2008 and newer four-stroke KTMs (and some earlier models) use a timing chain tensioning device intended to develop its force using the engine oil pressure hydraulically. Sometimes the stock tensioner does not apply enough tension at low RPMs which can leave the timing chain in a slack condition, and you will hear the cam chain "ticking" noise. This can have disastrous consequences. Dirt Tricks has developed a simple, effective and failsafe replacement. The new tensioner correctly captures the oil pressure. Additionally, it uses a positive mechanical ratcheting system which prevents it from collapsing. 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). This means the following bikes:
2005-2012 all 250 four-stroke models.
2007-2012 450 SX-F and 450 SXS-F models.
2008-2012 all 400, 450, 505, 530 four-stroke models.
2009-2012 Husaberg 390,450 and 570.
* Does not fit KTM 690
