Suspension Lubrication

6 posts in this topic

Everyone reading this message do yourself a favour. Shut your computer down and go and strip your rear suspension .

My YZ426 is only 1 month old (max 300miles riden) however I decided to remove the engine in order to do a gear ratio change (1st, 2nd and 5th).While the engine was out I stripped the rear suspension linkages just to check them out. All I can conclude is that the Yamaha factory had obviously run out of assembly grease when my bike was put together.

The bearings condition were border line. Another month of riding and I would have been forced to replace most of them. Water had already entered the bearings and was mixing with the little grease that was still present. I count myself lucky, having just rectified the situation in time.

This is one maintenance activity you have to do asap !!!

Next stop steering head bearings.

Good point Craig.

WR400 owners have had the same problem with the stearing head. Mine was fine but many have complained that their bearing was dry as a bone. Probably true on the YZ too.

I did mine too. Turned out the original owner had done it, but it was still due.

When my YZ440 gets here I'm going to do it all before it ever sees dirt! :)

I stripped mine easlier this week..

F$@king lieing C&*@ of a dealer!!

I told him to lube all bearings etc in swingarm/linkage and headset..

He said he did it.. but when i strip the rear end I'm up for new bearings and sleeves in the rocker piece..

MAYBE get away without replaceing the others but they're worn a little..

F*$#!!!!

Ah.. that feels better! :)

I knew how well the factories greased things loooong ago! I greased everything before my 426 ever saw dirt. The steering stem and front wheel bearings still require the most attention.
