Hydraulic pump vibration

[JoeU27]

Hi, the hydraulic pump on my u27 excavator is vibrating excessively and shaking the cab. Also the hydraulics appear to be moving slower than they used to. It's only 2 years old with less than 200 hours on it. Is there a chance one of the filters has got plugged? I have noticed that when I extend the boom I get a a whistling sound through the hydraulics.

I've checked the hydraulic oil level it looks good and it is clear.

Of course my warranty just expired, So any advice would be appreciated.

The hydraulic pilot filter and the pump, the filter housing is vibrating excessively

Just for the record, I have 0 experience with that model.

However; I would start of with the “basics” by dropping the filter(s) and inspecting it/them (you may have to carefully cut it/them apart to inspect it/them)

Having a new filter(s) “at the ready” would be advisable as well.


EDIT: Cool mini-Ex though

Does that shaking occur at all engine rpms? And does it only happen when you are moving the digging controls or just when in travel mode?

I do have the WSM for your machine. However, its about 100MB pdf file. Let me know if you need one by PM and I'll find a way to get it to you.
