John Deere 300 Backhoe hydraulic pump replacement and repairs Part 1

[@rickdavis3518]

Do you happen to have the part numbers for the clam shell and rubber pin bushings and pump ?

[@slicksiderepairllc2822]

Sorry I don’t have those anymore.

Great video. I have one of these and the bucket moves very slowly but all the other hydraulics work great. I think I am going to replace the relief valve on the loader control valve stack.

[@slicksiderepairllc2822]

That sounds like a good idea to me.

[@Adirondacks4me]

There seems to be an upper relief valve and lower, which one ?

[@Adirondacks4me]

My 310B is doing the exact same thing.. High throttle and hardly any front bucket movement, all the other hydraulics seem fine.. chatter before it hardly started working at all. Relief valve sounds right but which one?

[@chrisevansgunshorsesranchi699]

I replaced the valve you are talking about and it didn’t work. I had to replace the pump main pump. I think the front bucket uses more fluid than any other actuator. Don’t waste your money with the relief valve. Good luck

Question: Do you not have to bleed out the air when replacing hydraulic pump?

[@slicksiderepairllc2822]

No

[@donaldellis9004]

Can you tell me what service manual you bought, I have a 310b

[@slicksiderepairllc2822]

Best manuals to buy are used John Deere ones off of eBay don’t buy anyone’s reprints.

Hello Very good video. I would like to know how long it took you to place the O rings in the steering column and than how long it took to slide the assembly back into place where everything sat well. Thanks!

[@slicksiderepairllc2822]

I did not have to remove that steering assembly to do the o rings and about a hour is all it took.

I have the exact same Tractor but the pump is a lot larger than yours. Mine don't have a backhoe on it. My problem is I have no brakes. Of course their wet brakes, everything else works good. Any suggestions on troubleshooting the brakes?

[@slicksiderepairllc2822]

One of my videos on that backhoe covers me fixing the brakes. Mine turned out to be a ball that fell out of the master cylinder casing between it and the transmission housing.

I have a jd 310 AD.. WHAT PUMP DO YOU RECOMMEND?

[@slicksiderepairllc2822]

I had good luck with that one I put on this backhoe. Came from a company over in South Dakota

[@johngoode8391]

Could you please post the name of the company in South Dakota where you got your parts?…….thanks

I keep getting conflicting answers about bleeding the hydraulic system. one tells me the air will work its way out and another tells me to bleed the air out at the pump. After reinstalling my pump, my steering did not want to work. used the bucket to lift the tires and they would turn. So there is air in the system.

[@slicksiderepairllc2822]

You do not need to bleed the hydraulic system. Nor do you want to should be over 2000 psi in it. I would guess there is something wrong in the steering column. I replace o rings in this backhoe steering column in later videos
