For lack of experience, I can't tell what to do before you try to start it other than drain the old gas and put in fresh leaded gas. The motor holds 6 quarts of a 20 weight non- detergent motor oil. The transmission and differential holds 17 quarts of 80 Ep transmission fluid. (The full level is the two check plugs on the left side of the tractor.) The final drives hold 1 3/4 quarts ( I guess 80 EP). They too are full when filled to the check plugs. I dont know the certain amount the hydraulic system holds but use a 20 weight non- detergent motor oil. There is a hydr. oil dipstick on the left side of the tractor. The cooling system holds 3 1/2 gallons. Check the breather's oil. Fill to the level mark with a clean 20 weight motor oil. Recommended spark plug sizes are: Champion- J8, AC- Delco- 45,and Auto- Lite AN7. After you have it running grease all the fittings(steering joints, brake & clutch pedals etc.)To get desired performance out of the lift system the Traction Booster pump MUST be correctly adjusted and the various links set right. We had the same problem. There is a diagram on the side of the battery box or you will need an operator's manual. If I've helped you out any write me and let me know. Glad to help.: I need your help. I have a WD-45 (gas) with a narrow front end, PTO and 3-pt hitch which has been in storage for approx 4 years and has not been started during this time. What should I do to get it started with minimal engine damage? What fluids should be changed? Should I try to inject some lubricant into the cylinders? What are the fluid capacities for oil and transmission/hydralic? What oil type is recomended? What might cause the 3 pt hitch to rise and fall on its own during operation with a bush hog? Is it possible to convert to a wide front end? I know this is a lot of questions, but I need serious help.
