I need to replace my small v-belt to the hydro pump. I see I will need to take the drive belts from the engine to the jack shaft off to do this. How do you do that first of all? Second I believe I then remove the three bolts you loosen to adjust belt tension and then the hydro pump will come off. This should allow me to put the new one on? Any help or tips would be great. Thanks!

I would suspect a problem with the alignment or tension on the hydraulic drive belt. I don't think I have ever changed that belt on my machine, and we bought that in 1995.
1. Make a careful note of the exact position that the engine is mounted in.
2. Loosen the engine mount bolts until you can slide the engine forward far enough to allow the hydraulic drive belt to be slipped into the inner position on the crankshaft. All you need is enough room under the big belts to slide the little belt under them into position. Lifting the big belts over the electric clutch will be a challenge, if not impossible.
3. Loosen the mounting bolts for the hydraulic pump.
4. Install belt, adjusting tension and alignment properly.
5. Restore engine to its original position, using the belt tension adjusting screw on the grind wheel side of the engine. Your owner's manual should have specifications for the correct tension on the belt. If you don't have that, call Rayco; they have a technical support area that will advise you. 1800-392-2686 Rayco
It is imperative that you do not move or adjust the jack shaft that drives the grind wheel. The positioning of the bearings is critical to proper adjustment of the cog belt that provides final drive to the wheel. Change that adjustment, and you have set yourself up for a very expensive belt replacement.

I did the change a couple days ago and it was very simple. Slide the motor forward, take off electric clutch, take off two drive v-belts, loosen hydro pump and remove belt. Have ground 8 stumps since then and it works perfect. The belt was very worn and tensioned to the max so it had to be changed. Thanks for the reply!
You didn't really have to take off the clutch. Since you did it without any complications, all is well.
Glad to have helped.
