First break down of the year which happened our first day back on the 5th. We got all the machines going to give them a run and get the fluids circulating etc and when I had came back with the 362 the boss was in the car park with the hood up on the HR600. He said it was like it had ran out of fuel.
Straight away I noticed the plunger on the fuel water separator filter head was depressed fully in so I knew there was an issue with that. I jerry rigged a fuel supply and got it back to the workshop.
I did the usual process of bleeding the fuel system but it would only run for roughly 30 seconds to 1 minute before it would die. If I bypassed the filter head it would run quite the thing no problems at all. I ruled out the filter bleed screw as it did have a small crack in it and I also ruled out the filter as I fitted a new one, it just kept doing the same. So I knew the problem was with the filter head itself, I stripped it down completely and there was nothing jumping out at me, so I priced one up, from Ransomes themselves it’s £526 + vat and from Kubota it’s £350 + vat. Jeez.
But I had a fuel water separator filter head and filter which is for a Jacobsen GP400 so I fitted that, I had to add some fuel line for it to work as the inlet and supply side are swapped round, but this works perfectly fine as I didn’t cut any of the existing fuel hose so it can be reverted back to the original set up if they ever fancy spending that much on a filter head.
The only real difference is the correct setup incorporates a sensor for detecting water, but the new set up is a clear bowl so you can visually inspect for any water.
It’s now running perfectly well. Other than the usual service I have a lift cylinder for the right hand wing deck to rebuild, it has an oil leak. It also threw a code for charge filters when I was test driving it so that will be solved when I service it.
The ridiculously expensive filter head.
