Just got back from my CIH dealer. When I was finally able to talk to the service manager, he suspected one of two possibilities. The easy check was to interchange the forward and reverse capsules. If this provides no improvement, he then suggested that the high pressure forward pump did not have proper pressure. It could be the pump, or the valve/relief valve bypassing pressure. It also could be the pump itself. (he hopes not...$$$) A pressure test is required, going in the diagonostic order as perscribed in the service manual. If the pressure is somewhat below minimum, and the pressure and relief valves are PERFECT, ( ie no scratches etc. on O-rings..) sometimes a couple of oil and filter changes/flushes will provide satisfactory performance in the interm. It is assumed that HY-TRAN oil is used. If a pressure test reveals unacceptable pressure and the valves etc are good, than the best answer is an experienced garage that does meticulas (sp) work is required. When Harvester assembled Hydros, cleanliness was extremely important. The local shop has a couple of dividers in it, and they clean and then pressurize the room prior to aseembly. Hope that this answers some points and is able to steer you in the proper direction. The shop here closes now until January 4th, so happy finding proper pressure!!!....... QR
