Ohlins Racing AB has issued a recall for a number of its aftermarket TTX36 shock absorbers. There’s a potential issue with the piston-shaft nut, “which in some cases has not been torqued at full metal to metal contact because the top spring is preventing the piston to reach its final position due to high friction.” If the defect is present, the shock absorber risks coming apart and Ohlins strongly recommends riders stop using the motorcycle until the shock absorber has been removed or corrected. The company issued a letter to owners, which is included in full below, which outlines the defect in more detail, provides part and batch numbers for the shocks included in the recall and gives instructions on how to seek a fix to the issue. – MotoUSA Ed.
Dear TTX 36 Shock Owner,
This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.
Öhlins Racing AB has determined that a defect which relates to motor vehicle safety exists in certain batches and part numbers of aftermarket TTX36 (TTX GP, TTX RT & TTX36 MKII) MC shock absorbers produced between 11-06-2013 and 02-19-2015.
Öhlins Racing AB is conducting a campaign to recall all the affected aftermarket TTX36 shock absorbers of the models and batches listed below to rectify the issue.
The cause for this defect is the piston-shaft nut which in some cases has not been torqued at full metal to metal contact because the top out spring is preventing the piston to reach its final position due to high friction.
Component assembly shown in figure below.
If the piston-shaft nut comes lose the result will be loss of damping and on some applications it can also cause the shock absorber to come apart. Either of these events may surprise the rider in a way that the rider would no longer have full control of the motorcycle, increasing the risk of a crash.
We therefore strongly urge you to stop using the bike until the shock absorber has been removed or corrected! It can be a safety issue to use the bike with the faulty shock absorber on the bike.
This assembly defect has been rectified and the issue does not exist on shock absorbers with an earlier or a later batch number.
Batch numbers for the shock absorbers in question can be found below.
You can find the batch number on the shock absorber, stamped on the cylinder head, near the top mounting bolt.
