I didn't have this problem until i removed the drive in question to replace the gimble bearing. Now when i use the single trim button to trim both drives, the one that i just had off is trimming slower in both going up and down.

I do not see any leaks and i checked the fluid in the pump and it is full. I didn't touch the pump at all.

any ideas ?? Would fluid be leaking if the rams are going bad ??

Is it possible air got in somehow??

Rick, i dont think so. i didn't touch the hydrolic system of the rams, just pulled the drive and reinstalled it when i was done with the gimble bearing and bellows.

What was the problem with Jays rams? where they leaking? how did he know he needed new ones?

His were leaking down,

after inspection we found that he must have gotten water in the system from bad seals, and over the PA winter, the housings cracked.

OOOOOPPPPS$$$$$$$$$$$$$$$$$

can you pull up on the drives and get them to move???(PULL HARD)...there is a rebuild kit...but most of the time it just needs a fidy cent o-ring...cake job.

I'll check tonight. thanks Joe.

Where is the O-ring located if needed to be replaced ?

Mine does the same thing .I think its just in the pump .one is just faster than the other

I've heard it sug here to run a heavier gauge wire to the slow one,haven't tried it yet

I've heard that different weight oils will make them trim at a different speed.

Rebuild the cylinders.
