Introduction

  • There are a number of combinations and it is essential you get the correct belt.
• Diesel Jimnys have one auxiliary belt which drives all auxiliary engine devices.

You should not purchase based on guidance below - you should identify the correct belt for your vehicle elsewhere.

Tensioners for Jimnys 3

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;

You 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.
  • Example aftermarket tensioner is SKF VKM66009

• Universal specification for a fully compatible bearing from any aftermarket manufacturer (SKF, Timken, FAG, Koyo, etc.) is: 60102RS.

• 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• NSK has allegedly superseded it with the bearing model 6010DDU.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 NSK bearing.
  • It is NSK 6010VV.
• 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.
