Hydralic pump drive belt problems.

[Groo]

I have a Timberking 2000 sawmill that is eating drive-belts way to quickly. The factory belt was an absolute joke and rated for way less power than it was asked to transmit. The better belts I have been picking up locally aren't lasting the greatest either. I am thinking something has to change.

I am thinking either just getting larger pullies (and a corresponding longer belt) or since I'd have to change over everything anyways, possibly converting it to a cogged or micro-rib belt.

Another idea I had would be to add a spring loaded belt tensioner to keep a more consistent belt tension. Think that would make a significant difference in belt life?

Its a full hydro machine. The stock pullies are about 4.5" diameter and the stock belt is 31"

Could you go double pulleys?

I am sure the belts are HP limited.

Spring tension would probably help.

Try some Aramid belts. Heavy Duty Aramid Belts

Above a certain HP, it seems they go to cogged belts or serpentine belts.

Double pulley makes a huge difference . I had to do it when I repowered my tractor from a Cummins to a Cat the pump drove off back of engine in the Cummins app ,the Cat 3208 I had to build a belt drive system and like your system one belt wasn't enough.

oops, I think I typed in in wrong. There are two belts, the blade belt is a double belt, and it is doing fine. The hydro belt is the one that is giving me troubles. sorry if that was unclear.

After a little more research; It looks like the replacement belts I have been getting are light duty belts too. I guess the next step is to move up to a Kelvlar belt.
