I"m hoping some of you with experience can answer a question about my DBG Roosa-Master. Yesterday I started my '65 4020 and it revved up to about 1500 when the throttle lever was set at idle. I gave the foot pedal a tap and the engine settled down and I used it for a couple hours on the hay rake with no problems. When I was done raking I shut it down and restarted it and it did the same revving up thing. So, I presume the flex ring is going to pieces. My question is this, is it possible to replace the flex ring with the pump on the tractor. I internd to take the pump off this winter (when the tractor is getting a valve job)and completely re-seal it and whatever else it needs but I really need the tractor for the round baler in the next few days as my 730D struggles in that application. I can get the flex ring in a couple of days and I have Deere manual #2045 enroute (which I suppose will answer my question) but wanted to see what those of you who have been in these pumps have to say. I want to put the solid weight retainer in and eliminate the flex ring but will do that when the tractor is down for the valve job. Thanks for any info/advice.
