Belt tension adjustment question on LT

[rvparkownr]

I was checking the belt tension adjustments on my new LT2000-50 and following the books specs but something does not seem right. The book calls for a 2" measurement for the spring compression on the pump drive belt. After 17 hours the spring was measuring 3 1/2" . I don't know what the delivered measurement was but if I would try to compress it down to 2" now the spring would be completely compressed together with no space between the coils. This doesn't seem right. Is there a typo in the book or maybe a change in production. The SN on this machine is 5044339

The new measurement should be 2 1/4 sorry I did not get back to you sooner :)

I'm sorry to question this, but that still seems to be compressing that spring past what seems right. I want to do it right so to be sure we are both talking about the right spring. This is the one located under the left rear of the LT200050D near the left rear tire with the bolt that goes thru the frame and it tensions the pump drive belt?

As long as there is tension on the belt and it does not slip,it should be ok.Too much tension will cause too much load on your pump input shafts,and they may fail.Why don't you ask your dealer to look at it to be sure. ;)

Thanks for the imput. I had ask my dealer and he thought the 3 inch looked about right. I had tightened it down a little to about 2 3/4 but today with about 21 hours the belt failed. I know it had been slipping because when I picked the broken belt off the ground it was so hot I couldn't hold it.

The reason I was concerned about this was that my old Snapper Z1805 broke a pump shaft when the belt was over tensioned. Now I'm pretty confident with your 2 1/4 number. Sorry I questioned it, I'll never doubt you again:).

Not that this is the cause of the belt failure, but out-of-line pullies will also cause extrodinairly high belt temperatures.
