Schmittparts is delighted to offer these precision manufactured replacement gears reproduced exactly as original to F&S works drawings finished in original treated state with dark finish. These replacements are suitable for all Messerschmitt models KR200, KR201, and KR175 - also a direct replacement for the identical gears used on the Nobel 200. Note that special workshop equipment is necessary to remove the 4th gear from the layshaft allowing the two loose gears to be re-fitted to the shaft. Note also that the 4th gear is an interference fit on the layshaft – do not attempt this replacement without the equipment or necessary expertise. Gears are supplied as a matched set and must not be used mated to an old used 2nd / 3rd gear.
