Re: Cropmaster lift piston rings

Thanks for the replies, it's for a customer as the rings are stuck in the piston and one is broken on his tractor, I will give him David brown parts phone number, I found them on the website db2d posted. Cheers

Re: Hydraulic relief valve

Hi, yes the relief valve is definitely opening with the screaming noise, the feeder only has one top link hole but the top link does sit relatively parallel with the lower links.
