    Rebuilding Branson 4720h Kukje A2300. What I have learned so far.

    So I received the cylinder head and pistons from China. They are absolutely identical to what was in the tractor. Even the casting numbers. So for those that are interested the 1700 200p and 2300 are Cummins engines. All of the parts interchange. There's no need to purchase the parts from...

    Rebuilding Branson 4720h Kukje A2300. What I have learned so far.

    I think it was poorly taken care of and people use starting fluid to start it. What kind of smoke does it have on startup? White blue or black?

    Rebuilding Branson 4720h Kukje A2300. What I have learned so far.

Trans, etc are fine and don't leak. 1) 1 bad injector 2) 1 bad glow plug 3) broken compression ring on #2 and bad overall condition of the piston and other rings 4) cracked cylinder head on #2 between the intake and...

    Branson 4720h Engine replacing rings

    I have been communicating back and forth with a seller on Ebay in China. They a very responsive and even went out and mic'd the pistons and pins. Look as seem exactly as the parts removed. I am ordering their rebuild kit. It seems that the A2300 engines are the same except for the piston design...

    Branson 4720h Engine replacing rings

    Well, at $1,200 for a set of rings. Add some pistons and gaskets and may as well buy a rebuilt engine. You read that correct $294/per cylinder, I am going to order the Chinese stuff. Looks identical. Good reviews. We shall see...

    Branson 4720h Engine replacing rings

    I am not removing the engine and I think I will be OK. I was able to just push the piston out of the block with very little resistance. Mic'd the cylinders and am OK there. The second piston I could not get out as I will need a ridge reamer. But this first journal looks perfect. The softer...

    Branson 4720h Engine replacing rings

    Got the piston out of the worst cylinder compression wise. It had 240PSI. The manual says 495. The top ring is broken and the second compression ring has little spring to it.

    Branson 4720h Engine replacing rings

    I would do those things, but I'm doing an "in frame" job. I don't want to pull the engine. I will plastigauge it, though.

    Branson 4720h Engine replacing rings

    Yes. I bought the tractor at a very good price. The dealership was not a Branson but I have purchased used stuff from him before. He sold the tractor as is and I drove it all around for 1/2 hour. Lots of smoke, but everything worked as it should. It actually surprised me as the thing was just...

    Branson 4720h Engine replacing rings

    I have somewhat of an update. I took the head off and it looks as pretty good on first examination. I am going to mic the cylinders today. If good for the hone/ring replacement I will go ahead and pull the pan and the pistons for examination. If not, the engine will need to be removed and bored...

    Branson 4720h Engine replacing rings

    Yes.Cummins designed the engine A2300N2. I am in the process of cross referencing these. I have one supplier that said they may be able to match up the parts once removed. The Cummins A2300 is used in hundreds of applications such as backhoes, skid steers. Each is slightly a different design...

    Branson 4720h Engine replacing rings

    A chinese rebuild kit is in the 500$ range vs well over $2,000 with Branson. $230 for one fuel injector. Unbelieveable. Every where I look at rebuild kits for nearly every other brand the prices are similar vs Chinese. The tractor is great, but this kind of pricing makes owning one long term...

    Branson 4720h Engine replacing rings

    I am looking to replace possibly some pistons and rings in my 4720h. I contacted 2 different dealers and found the price for a set of rings on ONE cylinder at approximately $250. Read that $1,000 for a set of rings for all 4 cylinders. Pistons were about $230 each. I have never heard if these...

    Rebuilding Branson 4720h Kukje A2300. What I have learned so far.

    Sorry for the late reply. The bad injector was in the better cylinder (360psi). Any thoughts on using an engine flush and then changing the oil again? I put 5-30 synthetic in it after the oil change.

    Rebuilding Branson 4720h Kukje A2300. What I have learned so far.

    So, I went back outside and acutally squirted a decent amount of oil in the engine. The compression went up a good 20 PSI. So, it seems clear that the issue must be rings/pistons.

    Rebuilding Branson 4720h Kukje A2300. What I have learned so far.

    Yes. I am not sure as well. I did put in about 12 drops of 3 in 1 oil. Perhaps not enough or too thin?

    Rebuilding Branson 4720h Kukje A2300. What I have learned so far.

    My newly acquired Branson 4720h has been smoking at startup and then just a bit if running at mid to higher rpms. I spoke with the Branson dealer and he thought it might be injectors. So, I tested them and did a compression check. One bad injector, one bad glow plug and the following cylinder...

    front axle 4720h oil

    The manual says to use hydraulic fluid. But, the cap says 80W. I admit I changed mine and put hydraulic fluid in. Kinda thin but I am convinced the old oil is hydraulic fluid. No distinctive smell and thinner. So, what gives?

    Injector pressure of Branson 4720H

    Well, I got my tester today and found out a few things. The injector on cylinder 4 opened at 1900 and then at 2100 and back at 1900 so I don't know what that means. Cylinders 2 and 3 opened right about 2100. But cylinder 1 at first opened and then would not open even at 5,000 psi. I took it...

    Injector pressure of Branson 4720H

    Thanks. I will pick one up. Once the tester arrives I will check out the injectors. I also wonder if the diameter of the cylinders and pistons are the same with and without the sleeved blocks.

    Injector pressure of Branson 4720H

    Hello all. I bought an older Branson 4720H which I believe is a 2007 model. The tractor smokes a lot. Blue smoke but also white. The fellow at the shop I purchased it from (not a Branson dealer) sold it to me as is and thought it might need rings. In going through the tractor, I decided to...

    Branson Red paint Match?

    Is there any more info on the matching Rustoleum paints? Hoping to get some paint to make my 4720 look nice again. Also looking for the grey/black of the rear end. I am political, but even though this thread is 3 months old, lets keep it about PAINT.

    TYM T273 Moves backward but not forward. Help!

    I have a TYM T273 with 700 hours on it. Everything worked fine until I changed the hydro oil. I changed the oil and filter (WIX) and forgot to clean the screen. I used it to cut the grass but noticed that in high it would whine and have pedal resistance. So, I cut the grass in low. So, I tried...

    TYM 233 PTO doesnt work. Oil level very high

    I bought a 2009 TYM 233 and the PTO in not working. When I bought it, the owner had a 5' brush hog on it to show me it worked and it did!. But now at home, it does not work. The button illuminates but the lever that you push to engage is like loose, just can move back and forth real easily like...

    I have an issue that has just started with my tc 33d. When I turn on the headlights, the engine dies. When I immediately turn the ignition on again all lights are off including the headlights. But, the emergency flashers work. If I wait a few minutes, turn the ignition back on sometimes the...

    TYM T233 with T200 loader valve body question No Float

    Hello everyone. Hope someone can help me. I recently bought a TYM 233 with the T200 loader. Loader worked good except no float. I read the thread about removing the cap and cleaning it out. I did that and foolishly reversed them and broke the cap on the outer side. I fixed with JB weld and a...

    Jerking loader, 3 point hitch and weak front wheel assist

    I have a TC33d that I bought used a couple of years ago. I have had the PTO gears replaced as well as the entire front axle gear/bearing/seals. It has the stock New Holland loader on it as well as supersteer. 2100 hard hours, I think. The engine runs strong, no blow by, good power. I have...
