Bobcat e 19 pump whine

[French Bob]

Hi everyone,
I have a Bobcat E19 2015, I bought it with just 400 hours, it had been serviced correctly and was in like new condition.
But had a whining noise under load , power wise it seems OK but is a bit lazy on low revs.
I had the pump removed and checked bit the company said it was I good condition with no signs of wear.

It sounds like cavitation in the pump but I am at a loss to the true course of the problem. Thanks

Can anyone help me with aby suggestion

Is it sucking the pump intake pipe flat?

Wonder if the Rep will be along shortly?

They just seem to whine, I’ve seen it mentioned before. And they are very lazy on low revs. Want a bigger lump in them really, but emmisions bullshit...

Today I joined you on scrapheap challenge mate... New master cylinder seemed to sort that dumper out, did all the oils too. Back axle was particularly bad, glad I did it. Hopefully she’ll do me a good turn.

There he is....

 

[doobin]

Right on cue

Yes they have a very noisy pump, just a trait of them.

Not a lot of use either, my Kubota U17-3a doesnt whine but it needs a bit of revs to go,wouldn't call it very lazy but Im clicking on to what Doobin means re emmisions and small engines.
U17-3 is 898cc E19 is 720cc
My old Jcb 801 was 1100cc which prob explains why it would work just idle without struggling...new 18z JCB is 760cc i think.

720cc seems very small for 1.9t machine

Dx10z needs full revs, pretty much for everything. Idling is pathetic and mid way just doesn't seem to deliver..... Not that full revs makes a massive difference

I don't run the e10 and my dx10 at full revs and I've never found them lacking one bit. Odd time I may knock them up a bit but still not full bore.

I find my only has three positions
Idling
Half for slow tracking through narrow areas
Full for everything else
