As a part of our continuous developments and a result of field experience, a number of important changes to our engine maintenance schedules have been introduced.
One of these changes covers the checking of the torque of the alternator flange bolt.
Please check our latest service bulletin on our website.
Go to engines and click on the engine you have (e.g. UL350IS) , select the tab " service bulletins" and go to the file "2018-02"
Always use the latest mainteance manuals .
They can be downloaded from our website http://ulpower.com/en/engines/ where you can find the manuals on the related engine pages by clicking on the tab “manuals”. A detailed lists of changes made, can be found at the last page of the manual.
