Hi, There are 21 Conservation Service bulletins (document type = Conservation Bulletins) in the members library, together with another 1100 or so documents. Membership starts from just $40 per annum.
 

Hello Phil,
Thank you for bringing these discrepancies to my notice. I spent many a long hour along with others uploading files, renaming them and adding them to the library. I'm afraid my fingers are not as slick on the keyboard as they used to be (and I'm not sure my typing was ever that good).
In the early days of hydraulic excavators or so I'm told, Cat sold and supported the range of Mitsubishi excavators and the engines that went with them. After some discussions as to whether we should include the Mitsubishi files in the library, the view was that we have the files anyway, the storage costs are minimal and they may help someone either now or in the future.
I will try and fix the "conversations" and the duplicates in the near future.
Actually thinking about it, whilst the duplicates are definitely down to me, the "conversations" could be down to the irritating software we have these days that thinks it knows better than you do and constantly tries to change what you have typed !
I'm sure that there will be other mistakes / typos in the Library and any that are reported we will fix.
