Tips and Tricks      

Eternal life for the indenting of the kick starter


A well-known problem in the NSU-Max is the wear of the teeth of the kickstarter shaft. It can go so far that the Kickstarter slipping when pressing.

However, the teeth can only wear if the Kickstarter has clearence between itselve and the shaft.
. This most often happens when the clamping screw ( 35 ) is not sufficiently tightened. Now, the clamping screw has only a diameter of 6 mm. This is for the biasing forces required for a firm seat of the kick starter not much. So it often happens that triggers the clamping screw and the Kickstarter wobbles on the shaft.

The simplest remedy would be, would use if you take the M 6 screw an M 7 Series or even 8- M screw. But apart from the fact that the flange on Kickstarter for this is a bit small, this would not be original and also does not look good.

Whoever attaches importance to original-like appearance, but still want to attach the kick starter sure who should be in relevant screw dealer a particularly high-strength screw quality 10.9 : better get (Say ten point nine) even 12.9. The screw itself has the designation DIN 931, M 6 x 32. If you can not get the normal hexagonal screw (DIN 931) in this high-strength grades, so you can, waiving the original structure, a hex socket head screw (DIN 912)  using the same dimensions.

Course is part of the high-strength screw and a high-strength hexagonal nut ( DIN 934 , M 6 ) . The screw nut should also have the quality "10". This "10" is stamped on each screw nut.

Such a high-strength screw connection, consisting of a 6 Series M Screw grade 12.9 and a M 6 nut quality 10 can be equally tightened as a conventional 8- M screw of grade 8.8 . A fortified in this way Kickstarter will no longer dissolve in the operation and the toothing lasts forever.
