Greeting again folks, You guys have helped me out with a number of questions in the past for which I a am very grateful. Now I'm back with another question which should be simple but it's something I have not been faced with before. I have been working on and making some repairs to a recently acquired Bobcat 642. Today I brought the machine into the shop to find and grease the three fittings on the drive shaft. I propped up the boom, raised the cab and found what must be 100 years worth of leaves, branches, oil, grease and the bones of a Tyrannosaurus Rex buried under six inches of this built up debris. I prodded around to try to find an opening which I hopped to use to push , remove or blow out this junk with the air hose in order to be able to safely power wash or steam clean the machine prior to working on replacing the drive chains. I have steam cleaned a machine or two over the years but have always had a few openings to have the steam and water drain and escape from without building up and entering parts of the machine never meant to be flooded. I have, too many times. had the steam or hot water come right back at me if it has no other place to go. I tried to crawl under the machine but I don't fit very well. I did not see anything that would be drain openings. Now I know you guys never let that much junk build up inside your equipment and once cleaned out mine will never see it again. My question is what is your experience with steaming or power washing the guts of these machines. Any trade secrets on this clean up would be greatly appreciated. Have fun, buckshot
