Jeff Kinnett 01-22-2013 13:33:10 66.87.7.48 Report to Moderator	purchased a WD 45 with a temporary plate over the PTO gearbox need to know if I take that temporary plate off will oil spill out everywhere ready to restore PTO gearbox, is there a fill plug to add oil for the PTO gearbox or does it get it somewhere else. my AC shop manual and owners manual does not explain [Reply]   [No Email]

In the diagram of the engine clutch shaft, the PTO gear drives the PTO intermediate gear. The Rear Oil Seal should keep the lightwieght oil in the Hydraulic/belt pulley reservoir from mixing with the heavy oil in the wet clutch/PTO chamber. Of course, seals tend to leak after 55+ years. The diagram of the torque housing shows that an original PTO cover would have had an oil plug in it. So, if yours is home made, make sure that your PTO drive gear and intermediate gear have their teeth. [Reply]  [No Email]

The PTO box does go where it is indicated in you diagram. If you go to page 55, you will see another PTO cover shown on the bottom of the trans/diff housing. Don't have a clue why a PTO would be located there as it would defeat the purpose of the hand clutch. Maybe some unusual version of the tractor (industrial or road grader) may have used a special purpose PTO here? Probably will never know! [Reply]  [No Email]

May be easier than pulling the belt pulley plug. Leonard PS: don't know why I didn't think of this before. [Reply]  [No Email]

Since you have the service manual, you will be aware that you need to check for condition of the intermediate gear and that the thickness/ number of gaskets between PTO box and the torque tube determine the backlash between intermediate & idler gears, which is specified at 0.004". If one gasket allows you to engage the PTO without difficulty, I'd stick with that. But, if it is really difficult, you might add another gasket. [Reply]  [No Email]

I just finished changing the clutch in my WD45, and opened up the belt pulley chamber. I tried to use an oil sucker to remove the oil in the chamber, and couldn't make any headway. as fast as I would empty my sucker gun, the oil would refill the chamber. I had to drain the hydraulic, tranny oil, to get the belt pulley chamber empty. [Reply]  [No Email]

The belt pulley gear train runs in the hyd oil, completely seperate from PTO/Tran/diff. Jeff Hint- easiest way to get those square headed filler plugs out is to use a 12 point socket that is 1/8 in larger than the square. Eg: 3/4 sq use 7/8 12point. 1/2 sq use 5/8 12point. Then with an extension you can get ratchet above frame rail & be able to turn it easily. Beats the heck out of skinning your knuckles down inside the frame rail. Probable the least messy to drain would be start with the trans drain. Some oil will remain in diff & PTO sections. Then go to PTO, remove 2 bolts at one end of plate, then just loosen, do not remove, the other 2 bolts, let the plate droop & guide oil into catch bucket. HTH, Willie [Reply]  [No Email]

Now speakinging with several tractor owners and the seller of my tractor I have not gotten a clear answer for me if the PTO uses its own oil or shares tranmission oil, and how to fill it. Pto has drain plug Thank you for tip on the belt pulley I will look at that next chance I get it doesn't have a belt pulley but I know I saw a plug on it any help from you would be greatly appreciated [Reply]  [No Email]

That is the belt pulley plug. It is a part of the hydrolic (sp) resivour (sp) that is integral to transmission/pto/rear end. The only thing is if you fill the pto/hydrolic resievour up it will drain into the rear end through the roller bearing for the splined shaft. If you have a AC service manual not an I&T it will show a lot better what I am talking about. Leonard PS. Wish I had my service manual here at the house and I would scan the pic's in and show you but they are at the house at the farm. [Reply]  [No Email]

The fill holes are located inside the frame on left hand, carb side, of the tractor. The plugs in the holes have a square head on them. One is large and the other small with the larger one being closer to the rear of the tractor. [Reply]  [No Email]

By the clutch pedal inside the frame rail there are two square headed plugs they both need to be filled with oil to fill all the areas.the pto is the lowest point of that oil cavity. I think the belt pulley plug is different. [Reply]  [No Email]

If that plate does not have a plug screwed into it (apparently it does not) you can drain some of the oil from the other two drain plugs and finish by loosening the plate and putting a 5 gal pail under it as someone has already suggested. It will be a little messy; don't you just hate the smell of gear oil when you get it all over yourself? LOL As stated, check the condition of that intermediate gear in the bottom of the tranny to assure it has no teeth missing. It can, however, be replaced without splitting the tractor.
