Hi Paul,

I divide these old tractors into two categories to keep 'em straight in my head because they are built completely different.

The small frame tractors (656, 666 and 686) have square rear axle housings, have a mechanically controlled T/A incorporating a planetary set and they normally will "over-run" while in T/A because of the way in which they are designed.

The large frame guys (six-sided rear axle housings) have a hydraulic controlled T/A as you know, and they should not over run.

You should feel a definite "shift-to-low" when you pull that stick back. If not, there is something squirrely going on with that low-side clutch pack or the hydraulic feed to it. Did the steering/brakes/drive train act okay when you shifted the stick? Did you feel any kind of a “jerk” or “hesitation” in the power steering when you shifted? If so, perhaps he should have replaced that front hydraulic pump also?

I wouldn’t give the blow-by a second glance unless it reminded you of a mosquito fogger. Would be more concerned whether or not there is any ant-freeze present in the oil.

A normal low-volumed rear end whine is completely normal. You’ve been on enough tractors and you’ll know when there is something abnormal about the gearing.

I’d go back and drive ‘er again. The second inspection always seems to give better insight. :>)

Again, this is just my opinion,

Allan
