 Product Description

buying-2-discount-300pxl-.png● 4TH CRANKSHAFT SUPPORT BEARING SET (GROM125RR 5-SPEED / MONKEY 125 5-SPEED 2021- / WAVE125i 2023-) (91008-K26-G01S)

● This specific 4th Crankshaft Support Bearing Set with part number 91008-K26-G01S is mentioned to be installed on the 31120-K26-G01 stator from the 5-SPEED JC092 MSX GROM125 EURO-5 & Z125 MONKEY 5-SPEED JB03 EURO-5 2021 onwards.

● The 4th Crankshaft Support Bearing was developed by Honda in 2010 as you can see in the exploded view below, and this to be used on their special 110 series engines to deal with extra load on the crankshaft.

● The extra bearing (9) in the generator / ignition cover (1) isn't only a great idea to be used on stock Honda engines, but certainly on engines with powerful big bore kits, and is in our opinion a great must have support for everyone who is thinking big bore, and certainly if you are thinking long stroke!

● The install is really easy, the NACHI JAPAN C3 bearing which is included in the kit need to be installed in the stator, and the circlip with number 13 in the Honda exploded view above has been replaced by a special bearing top cover plate, which need to be installed with 3 longer bolts and these are also included in the kit.
The special nut goes in the bearing, and support the crankshaft in the same way as the crankshaft extension on the Honda crankshaft above. The kit includes also a washer to ensure you have all parts to make an easy install possible.

● If you have a big bore kit on your bike then the extra support bearing in the ignition cover will reduce the vibrations greatly, and lower the risk of snapping your crankshaft in two pieces, more particularly on the flywheel side which is a very common issue, since this is the only side on the crankshaft which isn't supported by a bearing as you can see in the red image above (the crankshaft at the clutch side are supported by a bearing).

※ We recommend to use a new left crankcase cover gasket with the install of this set, and this gasket is available at the page with this LINK.

※ The RRP (Recommend Retail Price) we show above is based on the retail price in the U.S., this part retails between $110.00 and $140.00 and could be a interesting asset for you as business owner to consider supplying to your customers...

● THIS SET INCLUDES: 

  • 1 SPECIAL YUMINASHI CRANKSHAFT/FLYWHEEL NUT (BOLT ON SHAFT EXTENSION TO INSTALL ON THE CRANKSHAFT).
  • 1 NACHI JAPAN 16003 C3 ROLLER BEARING (TO BE INSTALLED IN THE STATOR).
  • 1 SPECIAL YUMINASHI BEARING TOP COVER PLATE
  • 1 CRANKSHAFT WASHER
  • 3 LONGER M6 BOLTS (TO INSTALL THE BEARING TOP COVER PLATE).
