Hello everyone. I've got a 1977 2640 with shuttle shift forward reverser. I've changed the hydraulic filter and sump screen but upon start up, I loose power steering temporarily until the main pump catches up. Also, the 3 point and loader chatter when raising up. As the tractor warms up the chatter somewhat goes away but not completely... I read that on non-reverser tractors that there is a check valve in the main pump line that prevents oil from returning to the transmission pump when the tractor is off. That allows the main pump to have a supply of oil on demand. Since my tractor has a reverser, I don't think that the main line running into the reverser control valve has this check valve? I pulled both of the oil lines off of the reverser and neither one of them had a check valve in the line like the non-reverser tractors have. So, for reverser tractors, what keeps the oil from draining back into the transmission and cavitating the main pump upon startup? Also, any advice on how to stop the chatter would be great! I know that I have a main pump charge issue... just not sure what the deal is.

Today's Featured Article - 12-Volt Conversions for 4-Cylinder Ford 2000 & 4000 Tractors - by Tommy Duvall. After two summers of having to park my old 1964 model 4000 gas 4 cyl. on a hill just in case the 6 volt system, for whatever reason, would not crank her, I decided to try the 12 volt conversion. After some research of convert or not, I decided to go ahead, the main reason being that this tractor was a working tractor, not a show tractor (yet). I did keep everything I replaced for the day I do want to restore her to showroom condition.
