In order to replace the broken generator built on my IH300U, the water pump belt has to be removed. The set screw and pulley collar were both not only rusted in place but painted over. That meant either busting knuckles or a complete front end tear down to get it loose. And a least one full days work.
IH wanted $16 for a new belt, $5 at the hardware, either way was a lot of work.
Harbor Freight had the adjustable link built for $24 and with my 25% coupon it was $18.
I got the link belt home, took it apart a few times so I knew how to do it and it ten minutes I had it on the tractor. The belt ran smooth with less wabble than the rubber belt.
This tractor is my forklift and I used it the rest of the day moving some old concrete pieces from the barn back to the creek and the belt gave no problems what so ever.
I read a post from a guy who has had one of these belts on a Farmall A for 5 years.
There are two mfg. of the belts, one is green and one is red, they are both good belts.
Connecting the two ends of the belt while its on the tractor is the only difference from this instructional video. https://www.youtube.com/watch?v=QLkHa257vmw
If you can't stand the thought of having some "new fangled" gadget on your tractor then pass it up.
If you want to replace your gen belt in ten minutes then give it a try.
