818 winch pto assistance needed - Steel Soldiers::Military Vehicles Supersite

I'd like some input into a problem that I'm experiencing with the winch pto on the 818. I've had to remove the pto shaft, as the pto wont shift into neutral, regardless of it clicking into either of the neutral positions.

I can shift through all 5 positions, but the pto shaft will either turn clockwise or counter clockwise (depending on position of the lever) and won't go into neutral, thus always turning. So there are really a couple problems:

1) pto neutral problem
2) Driving the 818 with rpm above 1800. There is a warning sticker indicating that the engine shouldn't rev above 1800 with the winch drive engaged.

I did put the shaft back on the winch and pto to test the functionality of the winch itself...by using the truck clutch and sometimes it would engage and function and then sometimes it wouldn't (pulled the Kubota with brakes on...back a bit). I'm quite certain that the winch has a problem as well and an overhaul of some sort is required.

Could I get some suggestions on the best method of troubleshooting the pto issue to begin with. I'll tackle the winch issue with the TM later, but want to ensure that the pto is operational before I take the truck on the road and rev past 1800 rpm.

Appreciated,

Andy

Andy, it sounds like you need to remove and inspect your pto. It is very easy to do. Just drain the transmission oil. Be careful of your gaskets, reuse or measure the total thickness of them and replace them with the equivalent thickness( check for proper backlash before removal). Once you remove and clean your pto, your problem should be easy to determine.

Shall do then...appreciated.

any new news on your pto problems andy????

I've honestly not dug into it yet. I've been busy with chores around the farm while I'm home with the new baby. I'll dig into it, but not sure when. I'll def letcha know what I find.

Here's the update. This may seem lame, but I'll share it anyway as it will prove to be some learning for others that haven't experienced this before as well.

As I had mentioned above, the pto would turn (with the shaft off it) no matter what position the pto lever was in. This included both neutrals. I checked it again this morning and the same issue was happening. Ok...so I turned off the truck and went underneath, while Jon operated the pto lever. We put it through all positions and when in both neutrals, I could spin the pto with my hand (still no shaft connecting to winch).

This led me to believe that it was spinning in both neutrals...but wouldn't with the shaft added (slight drag). I wasn't about to try and use my hand down there. I know this is a given, but in this day and age, it's really not. We connected the shaft and sure enough, with a slight load (just the shaft connected to the winch), the pto wouldn't turn while in both neutrals. We took the truck back to the north 40 and connected to a tree and operated the winch in accordance with the TM and dogheads excellent input from the other day on the phone. As a note, (I'd suggest getting good input about winch operations (asking lots of questions), even after reading the TM...just to make sure all points covered in the TM are understood correctly. Perhaps some don't need this, but I felt that I did.

The winch operated perfectly.

Basically, I shouldn't have assumed that the pto wouldn't turn while in neutral. We had turned the truck off and put the pto in neutral and fired her up, but it would still turn when we fired the truck up(weird to me). Anyway, this was something that I learned and decided to share it with the group.

must be the oil flowing around the gears i have heard of this before ususally with front end shafts turning on a ford 4wheel deive while xcase is not engaged. and expecially when oil is cold. the fluid flowing around would turn it just enought to see movemnent but not as much as the engaged rear shaft Tim

Makes total sense. Thanks for the input Tim

Andy, this is common. nothing to get worried about. the lower the temp is, the more this will happen as stated above.
