Oil & Fuel 3510i runaway engine

[marchanna]

First of all, 6 liters of oil on that engine is way more than it needs. Not sure where you got the 6.1 L number. This engine will take 4.3 L according to the manual. I'm looking at the manual for my tractor which is a F36R ( same as 3515 over in the US) but the engine is the same as yours.

I would get the proper oil quantity and rotate the engine by hand for a couple of turns to check if it is not seized. I believe you can get a wrench on the front pulley nut.

EDIT: For some reason, it says 6.1L on the TractorData website. However it seems awful lot for a 1700cc engine.

Here is a screenshot of the manual for my tractor.

My Kioti is a 2L and it takes 8L of oil. So, 6.1L doesn't seem unreasonable to me. The OP did say that he checked the oil level.

I would still investigate further. I'd hate to make an assumption and it turn out wrong and result in an accident.

I've just referred that since the engine seems to be the same for the 3510 and my tractor. Although I can't find anywhere what engine fits the 3510 or any info of the tractor for that matter. I know mine is a A1700T3 which has a somewhat shallow oil pan. In fact, the dealer did the first service last month and I was there watching and he just put about 3.5L of oil in the engine.

Anyway, the best option is to fill the engine till it gets the correct level at the dipstick. Obviously I don't want to turn the OP wrong and causing bigger problems after that. I've already said to check the level in my last post.

I wasn’t suggesting you were steering the OP wrong. One thing I would caution, is not going over on your oil change intervals. That’s a small oil volume and it won’t hold a lot of particulate before it sludges.

To be honest, this engine seems to run really clean for some reason. On the 50 hours service, the oil was still very clean and clear. It was just starting to get a little bit darker, not much though. This tractor doesn't have DPF which probably helps a bit. I'm at 58 hours now, I will see how it goes on the next service.

EGR is the big thing that causes oil fouling but the extra backpressure from a DPF will do it also.

Clean oil is good though. Hopefully it keeps up. Full syn, every 100 hours or one year whichever comes first will keep that engine running optimally for many many years.

According to this, 6.1 liters/6.4 quarts.

 

[ptsg]

Yes, I saw that also. However it says the same for the 2810 with an even smaller engine. 10 series info is really hard to find.

Branson Bob, how much oil do you use on your 3520?

If your Branson is like mine, the dipstick is confusing. It doesn't have a "low" and/or "Full" mark. It just as a series of 6 or so evenly spaced marks. The manual says keep it below the lower and upper limit, and shows a illegible picture of the dipstick the leaves you clueless as to where those limits are. Mine calls for some 6.4 liters of oil, which takes it to the next to top mark. The whole thing could be explained a lot clearer.
Is it concluded that Op's runaway problem was caused by an overfull crankcase? When I got my tractor, it was full of oil past the top mark up to where oil could almost run out the dipstick hole (!!!!). I ran it that way for 10 or so hours before I noticed and drained about 2 quarts out. Never had a runaway problem.

I suspect that the OP's runaway issue was not a result of overfilling. I'm not sure it was truly a runaway condition either, it may have just been a stuck throttle or something.

Additional note: I don't know a lot about the specs of this engine. Is it a Tier IV emissions? Could it have entered into a regen cycle?

 

[ptsg]

Yes the dipstick on mine is exactly like you described. I just leave the oil level to the top mark since I do a lot of work on steep hills and I don't want the engine to starve with the lack of oil.
