Hydraulic Pump "Tensioner and Belt " part numbers?

November 28, 2023, 12:09:47 pm

Does anyone have the part numbers for a replacement belt and tensioner on a 99 U270 with the 350hp engine?
I think I have a little too much rapid movement in the tensioner at idle, and the way things are at the moment, I better do all I cal to make sure the pump is not been damaged by bad lateral load forces.
Thanks
David

Got the replacement tensioner and "green" belt on the way. Amazon was really well priced, the tensioner on Amazon has only gone up $2 in 10 years to $101, and the belt has doubled to $54.
Thanks for the advice and the part numbers.
The comments on the heavy duty belt: is well worth  the extra $15.
I figure anything that may extend the pump life is worth the effort!

Rockauto has the best price on the tensioners, BUT unless your ordering some other stuff there at the same time, you do have to pay shipping.

Remember when shopping for parts, be very careful to get OE quality parts.  Way too many of the "replaces ...." , may be cheap, and ARE cheap.

Yes, it is getting harder and harder to tell what is a knockoff part and what is OE quality.  If the prices is "too good to be true", it probably is.
