Well, I searched through my receipts and could not find where I purchased a male x male adapter. The ones I had must have came with the tractor.

Some of you know the 9022F converts the 18mm male ORFS to a Jic 8 male.

By me trying to help owners with replacement aftermarket hoses for the China Backhoes ..... I feel /felt that the Jic 8 is to big / bulky especially up at the control valve.

I am having some of these adaptors being made as I type that will adapt it the a Jic 6. I hope to have the first run in about two weeks ??

I will be able to provide the adaptors only or adaptors with aftermarket 2 wire replacement hoses.

Anybody that has any interest can email me through my web site Jinma Dealer, Wood Chipper , Compact Jinma Tractors . Put 18MMXJIC6 in the subject line and I will let you know more as I do.

Ronald, I agree with you. I had always felt that the #8 was too big for the hoe since it is 1/2" ID.
#6 (3/8") would be optimum given the OEM pump's GPM output.

As you probably are aware, LiTW hoes use #4 (1/4") hoses and fittings. I think it is one of their engineering features that helps to seemingly dampen the jerky valve motions, aside from having better valves too.

Would switching to a #6 or #4 hose reduce the jerking of the hoe and would it still perform properly?

Thanks

From what I have seen so far (my opinion) the biggest reason for the jerky /un-smooth operation that some have / experiance is that the spool valves are to loose in it's bore ...... a to loose machining tolerance.

The factory adaptors between the valve body and the hose have a orifice machined in them that goes to each cylinder.

A #4 hose would have a lower flow rate with a higher pressure and a #6 hose would have a higher flow rate with less pressure. A good control valve makes a world of differance.

Our first adaptors has just been recently made and tested.

We have started a page on our web site that is under construction.

I will be receiving with in the next 7 - 10 days adaptors available for purchase.

These adaptors will allow you to up-grade / replace the hydraulic hoses and replace the control hydraulic valve with a quality aftermarket valve if you choose.

I made my own adapters a couple years ago to JIC. If you look at the hose pic you can see why they come apart. The hose was only inserted half way.
