Hi, I have a http://www.epoolshop.com/polaris3900poo ... parts.aspx
My pump is running and putting out pressure. When I look at the 3900 closer part 8 of the above diagram is spinning but nothing happens.
I did notice that part 25 seems to have a 3 pronged "teeth", but I can't tell if this is just leftover plastic or something that is prone to wear out. Part 8 has grooves where these teeth I think would go and would cause the single wheel to turn.
Is it possible that I just need to replace 25 and I am gtg? The chain drive system is engaged on the other side and I can see no other issues.
I love this forum, I just don't post here because you all have every topic covered so well.
