Finally got my MX255 back friday afternoon. A couple people have asked me a few questions about the pump conversion from the old CAPS system to a bosch P series pump so I figured I'd give a little detail. The kit is made by Area Diesel Solutions (ADS) out of Carlinville IL. I can't quote the exact cost right now since I havn't gotten the bill and it's wrapped up with an engine swap and other work as well. If I remember right the kit was around $13,500. Pretty expensive for a pump but since we plan on keeping this 1250 hour tractor a long time we figured it was best to go ahead and convert it now. The kit includes the pump, new injector lines, a brain box, a new throttle actuator, and misc hardware for installation. The kit also came with very detailed instructions with pictures of every step. Since I didn't install the pump myself I can't verify the instructions were spot on or not. The pump is a mechanical bosch P series pump but is run by an electronic actuator so there is no need for a throttle cable or any other mechanical connections. The ADS website claims the kit will keep the "same in-cab operation" as the original system. I seem to have two issues that I'd like to resolve if possible. #1 is the "constant engine speed" control doesn't work anymore. I'm not sure if it should or not, but I was under the impression that it would still work since the throttle is electronic and hooked into the original system. #2 is that my "end of row" function doesn't work either. I believe that is a problem with the programming at the moment because it won't go into record mode at all and when I hit the "step" button it just shifts up a gear. This tractor had all it's computers re-flashed while in the shop and I'm guessing it thinks the tractor has the automatic shift button rather than the end of row button. Still not sure if that is resolved if the end of row will control engine speed. Given the current status of problem #1 I would guess not. My Case IH dealer had to leave a bunch of sensors hooked up but hanging loose on the side of the block so the tractor wouldn't throw error codes all the time. Right now I can start it up and recieve no error messages or any other stored codes other than the problems from the original CAPS failure. (found caps pump was bad after reflashing computer....dealer obviously didn't clear codes while it was in the shop) Bottom line is that the tractor starts and runs properly (as far as I can tell right now) It still seems to have a little delay from the point of moving the throttle lever to the point of the engine changing RPM. It seems to be better than with the CAPS pump but it's still a slight annoyance that I'll get used to again. All in all you could say I'm a happy customer with the conversion kit. At least I don't have to worry about the CAPS pump failing again in the future. I'll post any updates I can if I find any answers to my small problems mentioned above. |
