Just dove into the pump today. It is pretty straight foreward. The O- rings on the delivery are shot. I'm going to replace them with synthetic ones. Hopefully they will have them at the local hydraulic shop. they have Buna type rubber. This is ok i suppose. any one have info on this type rubber. I'll do a seartch for it today. as for that indy. he wanted $650 in labor. they would have replaced the chain the accesable rails and the tensioner.Not a super complicated job but i could see it taking 6.5 hours. it took me days.they charge $100/hr. That is the going rate in wine country for quality service. too much for me! At least I have a spare car so i can drive one while working on the other. bye
