And here is a short video of someone replacing a key switch on a Jinma tractor that thinks they have an ignition system – which they don’t. Be sure to check all your fuses first because the key switch may not be the problem.

I also would like to mention, we try to keep the terminology consistent with the terms used by the manufacturer to reduce errors cause by language barriers, this is why it is labeled as an ignition switch and you will notice the rest of the industry follows suite.

Bob can you tell me reasoning that we should not use the ISO fluid?

I will try, but it should be noted that any oil is better than no oil at all. One could apply the old axiom “When in Rome do as the Romans do”. My skid steer with a Yanmar diesel, My excavator with a Mitsubishi diesel, and my Ford F-350 with an International diesel, all have fuel injection pumps lubricated from the engine’s oiling system. Attached is an official Foton FT404 oil chart, which has an independent oil sump for the injection pump. I believe the compressor oil suggestion started way back when in the Chinese Tractor Forum on TBN. I know it goes back to when I joined the forum in 2007, where it was discussed at length in many threads. It was assumed by some that the fuel injection pump was similar to an air compressor in function. Nothing could be further from the truth, as liquids, for all practical purposes, are incompressible. Here is one example: http://www.tractorbynet.com/forums/chinese-tractors/169700-injector-oil-question.html?highlight=compressor+oil Some compressor oils are formulated for use in rotary screw, rotary vane, and reciprocating air compressors, others for refrigeration compressors, and others for natural gas compressors. These oils use a diester or polyester base stock with various proprietary additive packages to suit the application. One of the main additives allows for rapid dispersal of moisture. They are available in ISO grades of 32, 68, 100, 150, and 220. None of them have an Anti-Wear (AW) or AGM rating. Next is the viscosity index, empirical unitless number indicating the effect of temperature change on the kinematic viscosity of oil (liquids change viscosity with temperature, becoming less viscous when heated; the higher viscosity index number of an oil the lower its tendency to change viscosity with temperature. So as an example, a 15w/40 CF rated engine oil will have a viscosity index of around 142, whereas an ISO 100 compressor oil will have a viscosity index of around 84, hence one advantage of using a multi grade engine oil. There are many other factors to consider to consider such as shear strength, etc., but I don’t want you to suffer from my oral dysentery any longer.

Bob, that is very useful information i thank you for that. From this point on we will be leaving the choice to our customers on which fluid they use but will offer both recommendations. The new Jinmas with the Perkins engines have injection pumps that pull oil straight out of the sump so this will only effect customers with older tractors.

This may help you.

Bob you peaked my curiosity on this one. I’m relatively new in the parts department here at Keno Tractors so I decided to look into this further. Anybody may use the oil they see fit, but this is what we recommend based on our experience gathered from thousands of transactions over an extensive time span. I looked up the numbers and we have sold 3,000+ Jinma tractors since we have been open, and actually we just stopped counting at 3,000. In the last year alone, we have sold 47 injection pumps of which only 5 of those were tractors purchased through Keno Tractors. All of which were recommended the ISO fluid which we use with every single brand new Jinma purchased here. Out of those 47 sold, 88% were new customers that were using an unknown oil. That tells me that the ISO must be increasing the longevity of the pumps lifespan. According to these statistics injection pumps seem to be performing significantly better on our tractors and the only thing we are doing different to the pumps themselves is just putting in the ISO fluid. I don’t understand your dislike of this fluid because all it is a high grade 30w oil that is easily attainable at any Walmart or Napa. Here at Keno Tractors we like to rely on hard statistical evidence which seems to favor our practices and save our customers money in the long run. Also, Trevor has not been in our parts department for a couple of years now.

Our mechanics use brake clean to clean the intank filter as it evaporates quickly and removes all tarnish. We also find that the hydraulic systems seem to work best when using HW46 hyd fluid or AW46.
