This is the power director clutch on the right side.

Most, if not all "shuttle clutches" were on the left side of the tractor. A shuttle clutch gives you forward or reverse, without shifting gears.
The "power director" is on the right side, and gives you 2 forward speeds in the same gear. |

TDC is Top Dead Center no matter what stroke it's on. A 4 stroke engine has TDC on the compression stroke, AND TDC of the exhaust stoke. Cylinder one and cylinder four are both at TDC at the same time, BUT, one is on compression and the other is on exhaust. |

Don't use 80/90 in the Power Director clutch. Use Universal hydraulic/transmission oil and even at that, until the oil temp is up to 150 degrees or more there will be some creeping in neutral. It will creep the most in LOW gear. It will creep the least in 4th gear. This is normal for an oil bathed clutch.

Not sure if you mean the power director or if its an actual shuttle but if its PD then when the oil is cold, it will creep. Once warmed up it shouldn't do it at all. That is if the transmission is in gear.

Use 80-90. If you ever find straight 80 then consider yourself lucky.

That’s what it was DR got it going . Thanks now to the shuttle clutch. It creeps when it’s in the neutral position. But it will work in the high and low positions.

Will try that thanks.
Also I am changing the oil in the transmission. The manual calls for 6 gallons of 80w oil. Is there a substitute or should I find 80w. Thanks |

The D-17 has adjustment on each pressure plate finger !! All the clutch pedal rod does is position the pedal either farther back or forward when released. I have tools made to be able to adjust finger height when the tractor is assembled. Assuming there's nothing mechanically wrong with your clutch repair, I'll bet the fingers are too far away from the throwout bearing. So they need to be moved closer. You still want as much freeplay as possible, but the clutch should release when the pedal is pushed clear down. Always test your clutch adjustment as soon as the engine is rolled up tight and two bolts installed. Place the PTO lever in gear. Clamp a 10 inch Vise-Grips on the PTO shaft at the rear of the tractor. Transmission in neutral. Hand clutch in neutral. Someone in the seat holding the clutch pedal 100% fully DOWN. You should be able to turn the PTO shaft with little effort.

The d-17 has no adjustment other than the pedal and that’s just for leg length. Gotta split it to be sure all is correct. Thanks

First check clutch adjustment. Depending on how hard it slid back together you could've bent the disk. Or put the disk in backwards.

[QUOTE=CE Mississippi] Double checked wires . All good . Timing ok . Now checking valve adjustment. A little confused. On page 18 of shop manual it shows what to adjust valve tapper gap to with number 1 cylinder at TDC . And also what to adjust remaining valves to with number 4 cylinder at TDC. On the D-17 number 1 and 4 are TDC at same ]
They are both up on TOP center but not TDC and the camshaft turns half speed of crank so the valve lash is adjustable on different valves in different positions. Not confusing when you understand how it works. |

Clutch free play is adjusted at the clutch pedal. The clutch pedal should have a set amount of distance while the pedal is back until it is pushed forward as it touches the throw out bearing. That distance is in your owners manual. I do not have a D17 manual so I would have to look it up to be sure. That adjustment if it is like our D15 is adjusted by detaching the clutch rod from the clutch pedal and turning it in or out depending which direction you need to adjust the free play.

I had to put a rear seal in the engine and the plate had never been changed so I replaced it while I had it apart. I don’t see any way to adjust it . Thinking I should’ve put a new pressure plate in as well. Live and learn.

Glad you got it fixed, running with exhaust valve not seated can (will) lead to damage, especially under working loads. As for the clutch I don't know. Ordinary dry disk single clutches they always tell you to adjust the clutch pedal free play per the manual. Too much free play may mean you effectively cannot push in the pedal far enough to disengage the clutch, could give a dragging effect. Could you have put the disc in backwards? Why did you change it, did the old one have the same issue? Wait for the guys who know to give clutch advice. |

They were all tight . Had to loosen all up and set to the right spacing. Not sure how to do the clutch pressure test .

I would still do a compression test. For our knowledge, how out of adjustment were the valves, would you say some were not even closing?

Also do a compression test and report on the readings. If there are wacky readings, it could be valve lash.

Got valves adjusted. Runs like a top thanks fellas. Now I have to work on clutch. When you push in clutch it doesn’t stop the tractor. I put a new plate in . You think it’s the pressure plate ??

I'm sure if you put new electronic ING. on, it needs timing checked and adjusted. MACK

Pull one plug wire off. Do it on every cylinder. If you pull one off and no change then you know something is wrong with that one. Just because they are new don't make them good.

First would be timing and firing order. Next would be carb adjustment
