I also read the other post you suggested. Since my PTO and back wheels BOTH lose power at the same time, I don't think it's the PTO override. Also, when the engines cold and the PTO level is disengaged, the tractor still takes a long time to get moving. It's a strange sensation sitting there in gear with the clutch out not moving.
The transmission clutch adjustment is straight forward - Mechanical on the outside.
I have an operators manual, but I'll pick up a service manual. Is that the book I need? I also see shop and parts manuals available on line. Service manuals are available for < $200, so that sounds like a good investment.
Thanks for the sage advice. I'll update! |
Hey KG,
The fact that tractor is sluggish to start with or without
PTO engaged is almost proof positive that your clutch is slipping and is worn out. The only remedy for it disk replacement. Transmission clutch is friction based, and so called
PTO ORC is a one way ratchet only, grabs one way and slip the other way. One of the guys has done an overhaul plus a clutch replacement. With permission
I'll post it below.
The first picture is the clutch for 1700. It might be a bit different in shape with 1715 but function is identical. You see the big flywheel, and a pressure plate with 3 brown color fingers. The clutch disk is sandwiched between the two.
In this picture you see transmission input shaft and a mechanism to push on pressure plate fingers. it includes a hub (cast) and a bearing that sits on top. You push the clutch pedal and bearing touches and pushes the fingers in causing the disk to be separated from the flywheel. All the external adjustment you do is only going to cause surface of bearing to get closer or further from the fingers and that's all. The only way adjustment can help you is if the bearing was constantly pushing the fingers at all times (way out of adjustment). in a fix like that you'll loose grabbing force (friction).
This is picture of my 1700 where you see how close the release bearing is to pressure plate fingers but not touching it.
The picture of clutch housing from top with steering column removed.
are you able with tractor off and clutch pedal out get a flat head screwdriver and move the clutch disk up or down? That is also a sign of major slippage.
I have IT manual that I bought for less than $20, it is okay for the price but not as good as service manual.. it is anemically adequate. I'll post the adjustment below for now till you get a manual. I still think replacement of clutch disk is easier job that replacing
pto internal ORC.
Good luck
JC,
