    first pass 200 lb/ft, then 350 lb/ft and then one more time to 350. Use anti sieze on the threads and washers. This is for a 3408, 48W prefix.

    Yep thats correct. It works on all 3400 series. Cat recommends a moly paste for the threads, but anti- sieze or plain engine oil works well also.

    Thanks fellows , I knew someone could help me out . Dealer service wasn't much help . Guess I'd better look for a service manual for future references . Thanks again , Cotterpin
