I drained all the hydraulic oil from transmission. Put in new filter, and just on the other side, I also took suction line off to put a new donut and steel washer in to stop a leak. When I started the tractor, the high pressure light is on. The lift arms won't come up, and no power steering. So I need help on how to bleed the air out. Thanks Tim ------------- 1950 WD 1959 D14 1955 WD45 1976 7000 B 207 |

| With someone on tractor holding clutch down, put air pressure in filler hole with engine at 1/2 throttle. Use a rag wrapped around air nozzle to seal filler. MACK |

I didn't have good luck w/ my OSHA approved air blowing nozzle. So I made up a gem. Set regulator at 60 lbs. In 2 seconds I heard the 3 pt hitch come up. The steering worked, and the light is off. Thank you Mack. Tim ------------- 1950 WD 1959 D14 1955 WD45 1976 7000 B 207 |
