    Posted: 13 hours 59 minutes ago at 12:38pm
1957 Series 1 D17, fairly low serial number. Unknown hours, tach was not functioning when I bought it, shows 3500 hrs but obviously more than that. What has me wondering:   
When the tractor is not moving, tractor in any gear--including reverse, and I shift the power director from neutral to either the high or the low side, it seems to have a growl or hesitate slightly as it starts the tractor into motion. It snaps in fine and stays engaged. It does not slip or lose power.   I've had it about 6 months. Pulled stumps with it, pulled an 8 ft wheel disk with 600 lbs of weights on the disk, no power issues, no slippage any gear 1 to 3, high range and low. Shifts from high range to low range and back while in motion/pulling the disk, plowing snow, or puling logs with no issues, does not do the growl then.

If I use the foot clutch, change from neutral to low or high, and start it in motion with the foot clutch, it doesn't do it.
      I've held the brakes, and also tried starting it from dead stop with a load on and off. No change, same situation. It does not "creep" when it is in gear with the power director in neutral.   
     I'm basing this question on owning a 1967- 170, and a 1974- 175. In comparison, neither of these does that: Both snap in smoothly and no hesitation. Both the 170 and 175 "creep" if the tractor is in a gear and the power director is in neutral with no load on.

Something to be concerned about or don't "borrow trouble" ?
Thanks!

Shooting from the hip here. My gut feeling is you have a bearing dragging farther back maybe in the differential or a final drive. We had a 170 that did the same thing. It turned out to be a axle bearing. One reason i say that is it doesnt creep in neutral. Of course it could be a brake

Just put new brake linings, springs on it this summer. With the rear wheels off the ground they spun freely by hand, didn't seem to have any play or drag. Didn't have any side to side or up/down slop on the rear wheels when I pulled on them by hand. Speculated it might creep when the oil was cold and thick but no difference between 80 deg and 15 deg.
I hadn't thought about jacking the rear end up to see if it had any inclination to rotate the wheels then.   Will try with rear end off the ground tomorrow.

My thinking was that if was further back than the power director it would do it on takeoff with the PD engaged. Since it is smooth and quiet when you let off on the foot clutch with the power director already in high or low it probably has something to do with the clutches in the power director. Do they wear down to the point where they get a little rough, noisy and cease to creep?

It sounds like the Power Director compartment is very low on oil. The dipstick is to the LEFT of the gearshift and takes a wrench to remove. It it has the correct oil level, if it was mine, I'd dump a gallon+ of diesel fuel in that compartment, run it for 10 minutes with the trans in neutral and the P.D. also in neutral and drain it all out and let it drip overnite. Drain plug is just below the clutch pedal and takes 1 1/8" wrench.  Refill with 2 to 2 1/2 gallons of 821 oil and give it a whirl.

Is that recommended for one that has been sitting for a long time? Or just as a service?

Prior to the series 3 D-17 (and any D-14-15), the Power Director/PTO gears compartment was just that....a compartment that never got the oil changed and there was no filter to clean the oil. The clutch dust mud laying in the bottom of the housing can get pretty deep and the diesel fuel will help to flush it away. He never acknowledged if it's even full of oil or not. I suspect very low on oil, or oil so muddy that a flush is needed to solve his clutch engagement noise complaint.

Mines a series 3, that mean the filter takes care of that problem?

Sorry for taking over the thread but it really caught my attention…
Thanks DrAllis!!
