Hello everyone, I have a 2003 Yanmar vio27-2 4400 hours that the left driver is slow and with no power only when goes back. When goes forward is fine. I did replace the hydraulic fluid and filter already but no luke. Hope somebody can help.
My vio27-2 needed the seals replaced in the center swivel because it was bleeding from one circuit to another. I had very similar symptoms. The blade would raise when I tracked forward. Reverse did much better. I would look at those seals. The new seal kit is different than the ones that came out. I feel they changed because of problems. 3,200 hours on my machine. Good luck, Wayne
Thank you Wayne for your reply. I did order the swivel seal kit and I'm going to install it in this days.
Vio27 travel problems Hi x19m3 Did changing the swivel seals solve the problem as I have it as well now
Yes I did and yes the problem was the seals. Replaced all the seals and the Vio works like a champ.
Stuart Lloyd I do have the Service Book for the Vio27-2 if you need it.
x19m3 I would love a service manual if their is some way I could get a copy it would be so appreciated
Hi again x19m3 Did you replace the seals yourself and was it much of a job. I do a fair amount of mechanical work but not on excavators. The seals are already on order
Hi x19m3 I could certainly use a service manual if it is possible to get a copy
Vio 27-2 Service Manual I can upload it to the Dropbox. I cannot email it because the file is to big (48.5 GB). Could you PM me your email address?
Changed seals Hi x19m3 I have replaced the seals with some improvement but certainly not fixed. I am now looking at the valves on the motor that may have some pieces of the old seals in them
Hello there, did you find out the problem and fit it??? Please let me know.
