      I believe those guys are just importers, not actual dealers like Tommy and Ronald that have a brick and mortar service and parts departments. I will always recommend staying away from importers because most often you get dropped like a hot potato once the final payment is made, and that is when the Bill of Lading is signed and your tractor or machine is placed on a ship. Then it's between you and the shipping company and/or forwarder.

          Rich is correct.

          Owner / Operator's Manual for the tractor.

          Parts Manual for the tractor.

          Owner's Manual for the engine.

          Parts Manual for the engine.

           

          NO MAINTENANCE OR SERVICE MANUALS EXIST IN THE FREE WORLD.

          (unless someone has put one together recently)

          You have to glean what you can from the Chinglish in the available manuals.

            Have you checked here? Scroll down. wink

            Or you can Google “Jinma Tractors in Kansas”.

                You mean the 2 hoses that are on the BH now. The one from the tank and  one to hydraulics??

                 YES, the pump ends.

                 

                Got this from another site…………..

                The first lesson we made, was that the PTO gearbox is the worst part of the whole system. It caused the first hydraulic pump CBN-E310 to leak through the gearbox

                With the new Prince pump, not only with the problems of attaching it to the Chinese fittings, I also needed to increase the size of the suction line hose, pressure hose to the valve block, as well as the return hoses. You won't be using this pump anywhere near capacity. Suction hose from the BH reservoir is a nominal 3/4″ ID, discharge hose to valve stack is a nominal 1/2″ ID.

                My recommendations therefore are to stay with the CBN-E310 pump, but use GREASE in the gearbox. NOOOOO! How are the upper bearings going to be lubricated?

                That is a post from someone very inexperienced, and it is their personal opinion. I had no problem connecting up the hoses to my Prince pump, in fact I even use quick connects because I leave the pump on all the time. See pic.

                  If I knew how to interpret the part numbers better I could advise, but basically what you will need is:

                  1) One #16 (1″) SAE ORB X 3/4″ (#12) Male JIC, 90° elbow.

                  2) One female 3/4″ JIC hose end swivel X 3/4″ single wire crimp.

                  3) One #12 (3/4″) SAE ORB X 1/2″ (#8) Male JIC, 90° elbow.

                  4) One female 1/2″ JIC hose end swivel X 1/2″ double wire crimp.

                  You will need to take the hoses to a hydraulic shop to be crimped.

                    This will greatly simplify the Prince pump installation. I recommend it, it saves a lot of engineering time. Prince Torque Bar Kit.

                      Nice videos Ronald, thank you. kissass

                      Nice dyno too. looks like an old Clayton portable. 

                      Could have sworn you said you would never do that unless you were pre-paid.

                      Did I send you a check? Hmm, no. hmmm

                      Anyway, you performed a pretty good lab experiment, which is what it was – a lab test under controlled conditions, which, and I'm sure you'll agree with me, has little bearing on the physical world. Or maybe you're making the statement that Chinese diesel engines are exempt from certain operating norms. The ball head in the governor and the rack are barely doing anything in your demonstrations. In the physical world, say plowing a field or “brush-hogging”, the rack and flyweights will be on a roller coaster while maintaining engine speed under widely and rapidly fluctuating loads. Unfortunately you can't see this because it's all inside. (there is a nice Plexiglas model at the Woodward school – check it out).

                      I think you are saying that it is nothing more than a superfluous check valve.

                      You will become very famous if you can convince Bosch, CAV, Kiki, Stanadyne, Cummins, Cat, Detroit, Mack, et al. to eliminate the fuel pressure regulating valve from their fuel systems. There are an awful lot of people besides myself that think and know they are completely necessary.

                      PS: I thought you were going to read up on diesel fuel systems? Guess you didn't yet, otherwise we wouldn't be having this discussion.

                       

                      Addendum: My wholehearted apologies Ronald on some of the personal comments I made, even though they may be taken out of context. I believe I was still a little miffed over your trolling me in on the pressure gauge issue. Now that I look back, I have to laugh at myself for getting suckered in like that.

                      I think that one of these days I'll go back and get my high school diploma, or take a GED test or something…

                        Good choice Ben. hailking

                        When you get your new pump make sure to check the rotation arrows. Since your PTO shaft turns clockwise, the suction side will be on the left. Good luck.

                         

                        Yes, it will fit on your shaft. wink
