I only go to the local dealer if I have to...They seem to think that their parts are worth three times more than what I can find on the net and they still have to order 'em. I.E. I broke the front axle pin and they wanted 900 bucks for the front axle and another 100 bucks for the pin. And a two week wait, I found it in MO for 300 and 50 and delivered to the front door. They want 25 bucks for the hydraulic filter in a MF 135, ouch..
As for the washers, I think I figured out a way, I was in the local hard ware store just looking and came across beveled faucet washers, I bought some and took my chain saw file and opened the center and used a 30-06 shell case cut in half and sharpened to make the diameter close to the same size. Now if the rubber will hold up to the diesel, TIME WILL TELL!
