||could anyone tell me how exactly multi power works and how to test to see if it is working properly. is ther a certain place you have to have the multi power lever to be going down hill. also do you start off in low every time you take off and can you change down. all information grateful
||Les I was a Massey Ferguson mechanic for 27 years it is a little hard to explain how the Multipower works but I will try. The Multipower is a shift on the go hydrauliclly shifted two speed built into the front of the transmission. When the shift lever is moved up into the high range position it sends pressure to the clutch pack to close the multi disc in the clutch pack. This causes the high gear on the upper input shaft to turn the high gear on the counter shaft.There is a rachet on the lower shaft that when it is in high range it will run the lower counter shaft faster than the low gear on the counter shaft is turning the racthet will racthet then to prevent it from being in both gears at the same time. When the shift lever is moved down into the low range position the pressure on the clutch pack is released letting the multi disc in the clutch pack spin free the low gear on the upper input shaft then turn the racthet fast than the counter shaft is turning and the teeth on the racthet start to turn the counter shaft. If the rear wheels starts to turn the counter shaft faster than the low gear is truning the ratchet lets the tractor free wheel & you have no engine braking. When it is in high and the clutch pack is closed the transmission is lock together with the input shaft & you have engine braking. If for any reason there is no pressure goin to the clutch when it is shifted into high it will automaticlly be in low range. Email at email@example.com if you have have further questions.
||The multipower in my 165 doesn't work. Is there an inexpensive way of getting it into high range and permanently locking it there to achieve engine braking?
