JCB 310S

[KB6930]

We have had this problem with a new Kramer, you can rock the third service switch to release the pressure but by the time you got out to the grab it’s built up pressure again. Sorted this week after some moaning to Kramer by fitting a pressure dump switch on the boom, the difference it has made has been dramatic. What was a bitch of a job is now easy, it was so bad we did think we were going to reject the Kramer over this issue. However they have told us we have to pay for this button which in my opinion should have been standard and it’s not cheap.

I know what is be doing with it !!! Dump it back in they're yard and change breed

We had same problem with 310s was accumulator can't tell you where it's at must be under cab somewhere

The accumulator will be for the hydraulic servo system, when it's running it will be to remove any pulsation in the system but when switched off it will allow you to operate a couple of functions with the engine off.

I had a price from the dealer for this accumulator , it comes in at over £260 ! That's if they are talking about the correct part . Anyone got up to date cost on this by way of comparison ?

Might not be the same but I had to replace the servo accumulators on my JCB shovel they were Citroen & I found I guy online that specialised in them, he supplied me JCB spec ones for £38 but was a few years ago though.

i would tell them to pay for the dump switch or take the loader back and refund. put the ball in their court.

U just use the function with the ignition on


Tried mine this morning...had about 20 seconds of continuous dumpage till it stopped dumping so must be accumulator related
