You will need to contact your JCB dealer, Vibromax was sold off by Case, then sold again, and I am thinking JCB bought them around 2005. Their is some parts books on ebay for the w252 every now and then. A older case dealer that has it's old microfiche/microfiche reader and printer around should be able to print some pages or have a parts book still around with a pub # that may still be in the system. I would check and have the s/n with you also before ordering.
