Default EX60-3 hydraulic pump gone

Evening folks

It is with a heavy heart that I say that my old faithful friend of 11 years has finally succumbed to her high hours and dug her last hole (I think that is the case but I am eternally hopeful!)

The pump has collapsed and on inspection there is a lot of metal in the main hyd filter and the pilot filter

A new pump will cost about 3800 plus vat

My question is whether or not it would now be unsafe to operate even with a new pump and a clean out as I believe filings can get into the valve block and potentially cause unexpected and unwanted movement of the rams due to blocking ports open etc

I know that this would not be a viable fix from a commercial point of view but I would consider investing in her over a period of time if she would be safe to use

Your thoughts greatly appreciated as always

Martin

If your main hyd filter is full of metal fragments, then these have all past through the machine already! If they are tiny tiny fragments, the type that turn oil a bit silvery, then you may get away with it with a few oil changes. But if big chunks have passed through, then there willl inevitably be damage to seals and spools, as well as motors

Changing the pump could be the start of a costly and complicated repair, which once you start, you won't have much choice to persevere with, to get her back to full health.

It a difficult one to call, especially if you are 'attached ' to the machine.

It may be possible to dismantle the other major components, to determine their condition? Some serious time involved in this task though, and money if you can do it yourself!

Serious time involved. I hate to say it but should it happen to one of mine it'd be Ebay

Every Pipe, Ram, Valve Etc will need to be cleaned of oil in order to know 100% it's right. 3800 is half the value of the machine really. As sad as it is someone will give you 4k for a dead EX60 and you could get a reasonable little 6t machine for 8.

I Feel for you

Have to agree, its a difficult call

Some will say fit new pump and flush system by systematically removing pipes and pushing new oil through, some will refill, run it for a few hours, operating every service, change oil and crack on trouble free.
For others it will be the start ( as mentioned) of a never ending cycle of grief as having flushed everything you then get a track motor or slew motor fail due to contamination, then a ram, then a spool stick etc etc.

A very, very difficult call to make.

Some would fit new pump, lowloader it to auction and hope to cover their costs.

Thanks folks

The advice is very helpful and confirmed my fears

I also have the doosan dx140 so the EX60 has been taking a back seat for a few years although she always seems to be working somewhere!

I will ponder my options for the EX60 whilst looking for a replacement which will either be a Kubota KX080-3a or a Hitachi ZX70 (other ideas always welcomed and sure to be contentious!)

A dealer friend is calling on Sunday with a price from a breakers that he uses but I think I'd rather grow tomatoes in it than have it scrapped!

I'll keep posting on here with any news worth relating


Cheers

Martin

If there's doubt, out it. 'What if' will always be in the back of your mind

Can you get the pump reconditioned?
I paid 1800 for a fully rebuilt Kawasaki pump on my js130

Rebuilding pump is the easy part. Getting all the contamination out of the system is the ball ache.

I've sourced a replacement digger which is hopefully being delivered in 2weeks so my plan is to either buy a recon pump or recon its own pump and treat it as a long term winter project!

I'm sure I may regret it but I'll give it a go!

Thanks for the advice
