Tensioners for Jimnys 3

Gen3-100x100.jpg


There basically two types of tensioners for petrol Jimnys 3:

  • One with a small center;
    • These are more common on the G13B engines;
  • One with a large center;
    • There are more common on the M13A family of engines;

Warning Icon.pngYou should not purchase based on guidance below - you should identify the correct tensioner for your vehicle.



Small hole tensioner

Small hole tensioner
  • This is Suzuki part number 49160-82A00.
  • If the bearing has worn, then it can be replaced by pressing the old bearing out.
  • A suitable bearing is available in the BigJimny Shop HERE



Large hole tensioner

Small hole tensioner
  • This is Suzuki part number 49160-81A00.
  • This tensioner is commonly called a "smilely tensioner" because of the appearance.
  • If the bearing has worn then it can be replaced by pressing the old bearing out of the outer rim and pressing the smilely centre out.
  • A suitable bearing is available in the BigJimny Shop HERE



Replacements

  • First of all, the BigJimny shop has a high quality replacement bearing for sale (read above).
  • However, if you for some reason want to replace the entire tensioner assembly (generally a lot more expensive), you can either buy the original Suzuki P.N. 49160-81A00, or one of the aftermarket tensioners.


  • By the way, the bearing which Suzuki originally installs in this tensioner is NSK 6010DU2 (that's at least the case in M13A engined Jimnys made in 2013).
    • That bearing has rubber seals on both sides.
    • Specifications are: single-row, ball bearings, deep groove, 50 x 80 x 16 mm
  • NSK has allegedly superseded it with the bearing model 6010DDU.
    • However, since the specifications of those two bearings appear to be the same, it could very well be the same bearing, but just a changed naming nomenclature.


  • There is also a "premium" edition of this bearing.
  • The "VV" suffix means that is has special "contactless" double sided rubber seals (and made of some super tech rubber), which effectively allow far higher bearing RPMs and operating temperatures.
    • However, this premium bearing is about 3x more expensive than the "ordinary" one.
  • This premium bearing may be an "overkill" for this application (in other words, the standard bearing may be sufficient), but an expert should give an opinion.
    • However, if someone wants to indulge themselves with this premium bearing edition (instead of using chocolate or sex dolls for a change), then buy NSK 6010VV.
