Hi guys, a friend of mine has a D17, and the power director won't stay engaged on the high side. It will stay in low, and will drive fine in high, if you hold your foot on the PD lever to keep it in the forward position. I looked at the quadrant, and I'm not too familiar with the D series. How is the PD supposed to stay engaged in either range? It looks like on the quadrant, the only notch is for the neutral position. The area on the quadrant for "low" and "high" just looks like a smooth flat area. I am attaching a photo from the AGCO Parts Book website of the quadrant. It is part #3.  Any help would be appreciated! He's tried adjusting the position of the quadrant, but that hasn't helped. Thanks!

| Jumping out of high or low range is usually because the ramp plates and rollers are worn out inside the clutch. The quadrant is for neutral only. |

Make sure the lock bolt on bottom is tight. Take away washers on the stop bolts so as to allow the handle to go a bit further forward. Those I think are the "easy ones". |

| Ok. I will relay the information. He said growing up they always left it in high range and rarely shifted to neutral or low. Maybe that's why high is worn more than low. |

The bolt on #4 in your diagram usually has a stack of flat washers. If you remove some of those washers, the hand clutch will hold better. My D14 was famous for jumping out of high 30 years ago. Removed some of those washers and never had a problem since. ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '63 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |
