THANKS CHRIS ,FOR ALL THE UP DATES ,WHICH ONE DO YOU THINK NEED TO BE DONE,SOUNDS LIKE IF A PERSON CHANGES FUEL FILTERS EVERY 100 HRS. IT WOULD BE FINE ,YOU THINKS.TIME WILL TELL,STILL LOOKING FOR 1650 FWA IN ANY SHAPE,IF YOU HERE OF ONE PLEASE E-MAIL ME .AGAIN THANKS JOHN. IF I HAD YOUR MAILING ADDRESS I WILL MAIL YOU SOME PICTURE OF MY ELTORO, AND OTHER FWA | ||

Most of the updates were minor, in my opinion. The big one is the fuel filters. With the amount of fuel that engine can drink, the older style of filters would get dirty and rupture internally, letting dirty fuel into the injection pump causing premature failure. If you keep the fuel clean and change the filters often (I would think the 100 hour interval you gave would be fine) you shouldn't have any trouble. The spin on oil filters are supposed to provide better filtration, but the cartridge type will work fine too. I think the biggest advantage is less mess during oil changes. An oil filter base from a 2-135 or 2-155 will interchange, then you would be able to use spin on filters. The oil by-pass problem was worse this time of year. The amount of oil pressure with the thick cold oil would get too high, and the bypass hole was small enough that the oil pressure would still get high enough that it would cause leaks. This can be avoided by letter the tractor idle for a couple of minutes before opening it up. I like to feel the oil filters for warmth before I rev the tractor up in colder weather. It doesn't take long for the oil to warm up in these hercules, since the oil is water cooled. During start-up, that makes the oil water heated. The others are pretty simple, and if the tractor isn't having a problem in those areas after this long, it probably isn't going to. I emailed you my mailing address. Look forward to seeing your pictures. | ||

On tractors equipped with the original fuel injection pump, the supply pump is a positive displacement gear type, that is at the rear of the injection pump and pumps a very large volume of fuel. Look at service bulletin #430 506, be sure that you have the bypass valve shown at the RH side of the photo. Without this bypass valve the gear pump will force fuel through the filter even if the filter is plugged and will force a hole in the filter. Note that there is a possibility that your tractor could have a model 100 pump on it, that pump has a built in bypass valve. | ||

bjstar, are you saying that original pumps did not have bypass value when they was new and needs installed now if not there,thanks john | ||

John: You are correct, the original PSJ pump did not have a bypass valve, thus the fuel had to go somewhere, cold or restricted filter would cause a ruptured filter element, dirt goes into the pump head and that's $$$$$$$$$$$$$$. |
