[QUOTE="Tazza, post: 27315, member: 82"] If you *must* remove the grease nipple, you can lift the arms up and block them, put a jack under the rear to prevent it from tipping back as the arms lower down. With the arms up a little, you can pull the lift ram out by removing the pins and sliding it forward, this will give you access to swap the grease nipple. Yes, the system will self bleed, it may take a little time, but it will go. Mine dood a few weeks on a full re-build of using it for a few minutes a day. Drive it around lift tlit then sit. Be patient. The rams will slowly leak down, this is generally control block wear or piston seals in the rams. I think a few inches an hour without a bucket is acceptable by Bobcat. As Jerry mentioned, if you have no external leaks and the oil level is dropping, you have a motor leaking into the chain case. As you have a 743B i suspect you don't have a reduction box on the chain case, your motor is a direct connection to the chains. You may need a new seal on the bearing carrier assembly. Check the oil as Jerry said, if its indeed leaking into here i can give more details about the seal. [/QUOTE]
