[QUOTE="brdgbldr, post: 127189, member: 7474"] It can take a while for all of the air to work out of the system. Run the machine for a few minutes and look to see if the fluid has foamed up. If it has you have air in the system. If it got to your motors after changing the lift and tilt cylinders it probably means that you foamed up the fluid while driving it and sucked air into the motors. Run the machine for a little without using the lift, tilt or drive. Check for foam. Once the foam is gone refill the tank. Do this until no foam. Repeat but use the lift and tilt slowly and start with just small movements. Check for foam, refill, repeat. Once you can lift and tilt fully, without any foam, then you can try the drive motors again. You can try to purge the drive motors by leaving the brake on and just slightly engaging one motor at a time both forward and reverse. This will open the bypass valve an hopefully push the air out.
