ULSD in 2007 chinese diesels

[Ranch_Hand_Supp]

Ron, great pics of the pump!! The Bosch pumps are very similar. Do you work on the pumps on your shop? I agree, the engine oil is designed for use in the pumps, it's got all the additives and everything needed to care for the pump. The big diesels have been doing it for many years.

I looked at your website, I'd like to see you sometime in the summer when I get back. I'm looking at a 20 - 30Hp model with a FEL. I assume you have some of these on the lot ready to go....

Thanks GearHead1, I am limited to how far I can get into the injection pump repairs due to the fact I don't have a pump bench. I send them out if needed.

I try to keep the 354LE's and 254LE's on the ground at all times.

You are welcome to come by.

If you are looking for a Jinma that has been truly serviced from one end to the other, a dealer that stocks parts , offers technical assist with pictures and performs in house repairs .... you found it.

Happy New Year

Great diagram! That looks just like a Bosch in-line pump!

I doubt you'll have anything to worry about with those pumps, it's definitely ine in-line. I don't know the differences between the compressor oil and engine oil, but I'd be inclined to believe the engine oil would be better for the pump.

The pumps are direct copies of Bosch pumps used on Buda and Perkins small diesels. The differeces are: Bosch has 3 degees less taper on the input shaft, 5 minute fix on a lathe.The Chinese did a slight mod on the govenor so the rpm range can be adjusted higher, like the 254 - 284 and 30 and 35 HP engine difference in engine rating is rpm. Its a good mod in one way, bad mod for the guy with the golden screw driver.
Sealing parts in the Chinese pump are NOT Vinton material so caution on what you lube the pump with, I use motor oil.
I rebuilt one of there pumps someone told the guy to use trans fluid, ate the seals and seats on the plungers.

Not to reopen a can of worms here. but since the thread was closed, I received an answer from the engine factory we will be using in 2007: The 2007 engines were certified using no.2 diesel, but ULSD will be better. This is for the ZN390 and ZN490 engines we are ordering now for 2007 tractors in our new lineup, but I susupect all engines will be OK. I know I am hopeful my 2005 CUmmins can live a long life on the new fuel, I still have a lot of coupons left in the payment book!

Chip your engine will be fine, you could run kero, jet fuel, even ethanol and not hurt the fuel system on your engine. The Army runs the same engine and pump in their all fuel trucks. Matter of fact a company (Penske Diesel) did a test in Africa for the Peace corp.and ran a come a long (cummins) engine to drive a big generator. The engine ran for 2 years without being shut down except for service ( oil changes and filter) the fuel they used was what they could get there hands on mixed with diesel, bio diesel, gasoline, kero, ethanol, airplane gas (cam 2).
The engine was taken back to Cummins and dismantled, wear was normal for the hours used and it had minor pitting on the valve faces they believe from water being in the crap fuel they fed this engine.
So don't worry yours will outlast that payment book.
Out of all engines tested, Power stroke and Dura max included the Cummins was the only one that made it to the end of the test, the others blew up.

The Army thought they could go to the one fuel concept, and they can but not without repercussions. The idea is to run JP8 in everything, the reality is the rotary pump on the hummer doesn't last as long (big surprise).

Read this: The reality of the single-fuel concept Army Logistician - Find Articles

Just FYI:
Hummer - GM 6.2 NA V8 diesel or GM 6.5 Turbo diesel V8 with a Stanadyne rotary pump

HEMMT / PLS - Detroit 8V92 - detroit fuel system (rack on injectors)

M113/M577 Armored Personell Carrier - Detroit 6V53 (rack on injectors)

5-ton - Old 5 ton - Cummins NTC-855 with Cummins PT pump, New 5-ton Cummins 8.3 C Series with Bosch inline MW pump or P pump.

Stanadyne pumps have always been a problem child, the old 6.2's a spring in the outer housing of the pump would rust and break and leave you stranded. Dead on the road for less than a $1.00 fix.
The Detroits such as the 671's, 8V71's, 6V53's and so on don't have a problem with pumps because they don't have a injector pump as you say they run off of a rack. In some cases to run the on jp8 in other services, other than military they have produce a different height lithe gauge to set injector height taller, I believe if memory serves me right.
Answer for the Military would be to switch to Cummins, after all it must cost a fortune in oil to keep them Detroits running, I believe they are the only engines that leak more oil then a old Harley and they love leaking fuel from the return lines into the engine oil and finally with wet liners they love to crack the block, but it keeps Devcon in business selling that goop to fix the blocks. I often wonder why the Military used those engines, they run forever if you have a fat bank account and like to wrench.
They would be better off with Cummins, Cat or even some of the older Mack designs like the 673 or 711.
Just my thoughts

HAPPY NEW YEAR

Hi Jim, you must have been in the military I assume or have been a diesel mechanic. On a different note, where in Western PA are you from? I'm originally from that area. I ask this as I am curious if you have a Jinma how well it starts up in the winter....

Hi gearhead, well both, was in the military years ago and did vehicle testing at Aberdeen Proving grounds and I have owned a Diesel service (pumps and injectors and engine rebuilds) for over 30 years, now 2 of my sons run it, as long as I am not worm food I still own it he he.
I am in Beaver county, 136 yards from W.VA, I can see the Shippingport power plant smoke stacks from my house.
I own a Jinma 354LE and I have never had a problem starting it in the winter. I use the compression release and turn it over a few seconds until oil pressure gauge moves and let it go and she starts, I have used glow plugs maybe 5 times when it was down around 0 degrees. One of my sons has the same tractor, he lives in Idaho in the mountains and he has had no problems starting his.

Guys I just wanted to quickly add my professional 2-cents worth on this subject. The new ULSD that is now coming on line across the nation is gonna be good for all diesels whether found in automobiles, light trucks, heavy trucks, generators or farm tractors. My heavy duty Cummins diesel and my Detroit Diesel 60-series in fact loves this new fuel recipe however I discovered one thing very quickly (as in within 10-minutes) after a recent fueling at the Pilot Truckstop. Because of the new fuels cleaning properties, all the build-up in the fuel tanks and fuel lines leading to the fuel filters came loose at the same time instantly plugging the fuel filters forcing an immediate engine shutdown.

This was the same effect that ethanol had on gasoline engines when it first came out. After I changed fuel filters, no more problem. Engine runs better than it did on the fuel it just replaced. So my advise to all persons who have diesels of one kind or another, stock up on fuel filters and keep a filter wrench handy whether on the road or in the field because you may need it initially. After you have filled your diesel tanks a couple times with this new ULSD "Ultra Low Sulfur Diesel Fuel" you will have no other problems from it. Your engines whether automotive, heavy truck, generators, or farm tractors will run a couple of degree's warmer because ULSD runs hotter than what we were using previous to January 1, 2007 but your engines will run quieter and smoother. Not everyone has ULSD yet but it's making it's way to your neighborhood very soon. Thats my two-cents worth and I hope you got your two-cents worth.
