Oil Viscosity

[Kamaking]

I have to disagree about having to use max rpms.
My Kama TS354C that I bought from Chip is my first tractor from China. I have used others for many years.

I believe it is much better to just use an rpm and gear selection that will do the job without lugging . I see no need to run at max or near max rpms unless needed. Running any tractor at max rpms when not needed wont make it last longer.
With the right gear selection there is no need most times for max rpms. With the kama TS354C in low range the power it has really surprised me . 1800 rpm with this tractor in a low gear range will do most jobs. Now if your in a hurry and run in high range it is a different story . I'm aware of where the max hp and torque is at but in my opinion max hp and torque is not needed for most jobs.
Of course we all have to run our equip as we see fit. I have a ford 2n that has been in the family for over 60 years "on DINO oil" and we still use it . Now that little tractor almost always had to be run wide open. This little Kama really has the right gearing and power for what i do. Whether or not it holds up is the only question mark. I believe it will but time will tell. Nice site and let me add to disagree is ok with me. /forums/images/graemlins/grin.gif

1800 is a good speed and while I don't have a torque curve in front of me, I am sure you are getting into the power band here. something like 1200 or less wouldn't be so good. Glad you like your TS354C!

to get back to the subject of oil viscosity, I put 15-40 in as break in oil, but i noticed the tag on the side of the block it states to use 10-30 oil and it is dated 2005 and i am wondering if 15-40 is still ok to use i know it wont harm the engine, but what about the epa ratings. even here in the sticks were starting to see alot of smog in the summer

Did it say actually say "10-30" as you typed, or 10W30? Because "10-30" is in line with what the Chinese manual specifies; 10W or 20W or 30W, depending upon ambient temperature.

10W30 on the other hand, represents a multi-viscosity oil - which historically hasn't been seen in Chinese tractors and implements (or manuals).

Besides that, I don't believe I've ever encountered a conventional 10W30 that was API rated for diesel applications. Regardless of your viscosity of choice, you must use an engine oil with an API rating of CF or better. Most 10W30s I've seen are API SJ or better; gasoline engine rated. And I won't use synthetics at all - at least not for the first 300 hours or so.

sorry to take so long to get back to this, but my manuals say to use 40 weight oil in the summer and 30 weight in the winter doesn't mention 10 weight at all( my manuals were at least updated in 2002 because that is the date on the back of the engine manual for export license approval) .

it does read 10-30 on the block but there would be no way that i would use straight 10 weight in the motor no matter how cold it is /forums/images/graemlins/confused.gif

there are few small kubota's that also recommend 10w30 oil for their desiel engines and the owners are complaning that the only place that they can get it is from kubota

jinmalover, I have seen the tag you are talking about.... I recommend 15w40 ...

heres a link from Shell on the 10w30

I'm told the benefit of the low number in the mulitviscosity oil (such as 15W40) is that it gets the oil circulating faster on start up. If you use the compression release to spin the engine and get the oil pressure up to near normal before you start, a multiviscosity oil probably isn't needed unless you're starting in extreme cold. It takes about 3 to 4 seconds of no load cranking of the engine to bring the oil pressure up to 55 PSI on my tractor, then I release the compression lever and the engine is running.

I've switched from 10W30 to 15W40 Rotella to straight 40 diesel engine oil (Castrol Assuron). I like the Assuron a lot and I plan to stick with it. I see much more consistent oil pressure from start up to full operating temperature with the straight 40 weight oil. With the 15W40, the oil pressure would drop off dramatically when the engine reached full operating temperature.

I was concerned that with the 40W oil, I may not be getting oil to the valve train as needed. When I recently did a valve adjustment, I had the valve cover off and I cranked the engine for a couple seconds but didn't start it. I had lots of oil at the rocker arms and it was flung all over the place, which is a very good sign for a cold engine.

My KAMA 354C is Pre EPA and has no compression release. The engine starts everytime within half a second of hitting starter. Based on your message Multi-Vis is probably the way to go so at leats a bit of "Thin" oil is pumping when first started.
