MEGA ZX-21 crankshaft recall
Situation
MEGA needs to do a recall on the crankshafts of the MEGA ZX-21 onroad and buggy from the first production serie.
Our supplier Picco informed us that unfortunately the raw material (steel) used for the first production batch was not strong enough to be used in connection with the new design shafts with the inserted big-end pin.
Although a lot of testing both by Picco and Serpent drivers has been done before production, still so far 9 engines have been reported with broken crankshafts. On a total of over 1.000 engines this is not so many, but to prevent any further damages and to prevent that MEGA drivers will loose results in racing we have agreed to do a recall on the first serie of engines.
Solution
Picco has supplied us with new crankshafts that have the normal integrated big-end pin.
All our distributors will receive the new shafts between now and 7 march.
The shafts will be replaced free of charge. The driver can do it himself, or have the dealer ro distributor take care of this.
Engines that have broken in the mean-time will be fully replaced ofcourse.
Future
Further tests are carried out with new raw materials and designs, as we are sure the system with the inserted-pin will proove better results.
As soon as the tests show the best possible results and reliability, then we will introduce it again.
We apologize for the problems that occur and hope to solve it as soon as possible. We thank you for the understanding, patience and cooperation.
Team MEGA
