Thanks for the replies.
I felt around the relieve valve and there is a little water squeezing out around it. I recall opening that a bit to slow down the revolutions last year. The pressure out of the unit it still excellent, the tail whips, rear jet squirts and still sucks well. I’ll try to tighten that down to see if it helps.
I threw him back in and he’s been cleaning for the past two days and keeping the pool as clean as ever. I just have been running it longer since it seems to stop on simple places it had trucked past before, like a the base of the steps. It is still climbing walls and getting to the water line, so I’m hesitant to pull him apart just to check the parts. I know one I have it in pieces it will be down for the count until the new parts come in.
Do the turbine bearings usually wear at the same rate as the wheel bearings? I’m going to buy new bearings for the remaining wheel and the idler pulley, so I’ll likely just replace the turbine bearings as well. How does the turbine hold up after three years? Does that often need replacing?
Another thing I noticed is the idler pulley does not contact the two wheels very well. The spring loaded lever is all the way engaged and still barley touches the tires. Is that from worn tires of a worn pulley? I may just purchase a new pulley and tires to cover all my bases.
Are there any other high wear parts I should look at as well? My local pool shop changes an arm and a leg for parts, so I’m buying them off the internet, where shipping on multiple purchases is killing me, so I’d like to get everything I can at once, or twice now.
Thanks
