1946 WL gearbox problem


Post by Hans » Wed May 12, 2004 5:56 am


Well, I have some problems with my Flathead 46WL gearbox, hope you can help me.
The gearbox is totally restored with new "NOS" parts inside.

The problem is :

When I shift from 2nd gear to 3th gear, it gives a high "klunk" from the gearbox. Shifting between the other gears is working total perfect. Also when I shift from neutral to 1st gear there is no problem at all. It only when I shift from 2nd to 3th gear I can hear this "klunk" noise from the gearbox.
After disassembling the gearbox ( again ) I found that the Clutch gear ( 2513-41 ) and the Shifter clutch, 2nd & high ( 2298-41 ) was worn.

What to do???????
Hope somebody can help me?

Some additional information :
The bike is totally original restored. ( no special modifications, or custom builds). The gearbox is include "reverse gear" and it works also perfect.
I use a 31 tooth front engine sprocket. My clutch is working fine, and adjusted correct.
I have adjusted the gearbox correct in additional to the service manual etc.

Hans, Sounds like you answered your own problem. Replace your worn parts. You can find the parts at http://www.jwboon.com
Also check your endplay at your clutch basket, & sprocket.

If the reverse was added it is usually different from the spacer it replaced and the end play will have to be corrected with a shim kit. also check the spacing on the forks. you will have to mske up some gages. see the TM
