dannyredfan Posted March 26, 2022 Share Posted March 26, 2022 I have a 2656 diesel. It has all ways ran good but the other day it would only rev up to half throttle. I changed both filters the first one was nasty, the second pretty clean. But didn’t help. I flushed the lines, then wound up draining / flushing the tank. It Was pretty bad. ( I don’t know the history of this tractor) I also took the screen out of the pump it was clean. Then replaced the rubber hose from filter to pump. I have good flow of fuel to the pump. It will rev. All the way now but only runs a few seconds then slows till it dies. It sound good while running. I also took the fuel cap off the tank iam at a loss about the only thing left is the pump.

Reichow7120 Posted March 26, 2022 Share Posted March 26, 2022 Look at the return line fitting off of injection pump and see if its plugged. You could have a E ring going South and coming apart and blocking the return fuel line off of the pump. If you pull the check valve and its full of crud, this is you're problem. 3 Quote Link to comment Share on other sites More sharing options...
CIHTECH Posted March 26, 2022 Share Posted March 26, 2022 Governor flex ring is out to lunch, loosen the side window while its running and let it fast drip to relieve case pressure. Bet it will run fine. 4 Quote Link to comment Share on other sites More sharing options...
dannyredfan Posted March 26, 2022 Author Share Posted March 26, 2022 Sure enough. I thought about the return line took it off and no fuel came out, line goes in the bottom of tank. Got it cleaned and it ran great for minute or so then died quick. Checked my phone. Went back and loosen the inspection cover. Runs fine, tighten it back up started to die. Loosen it runs fine. looks like it’s going to be leaking now. 😡 just kidding I will fix it. 4 Quote Link to comment Share on other sites More sharing options...
dannyredfan Posted May 7, 2022 Author Share Posted May 7, 2022 Well decided to repair it myself. Thinks went OK at best lol. But putting the final peaces together I messed up a little rubber plug that didn't come in the kit. It goes in the bottom of the end cap. Anybody know where to get one?

Diesel Doctor Posted May 8, 2022 Share Posted May 8, 2022 If you are talking about the plug that goes into the "OUT" lower port, that is a common pipe plug. You can screw a gauge into that port to check the transfer pump pressure. Quote Link to comment Share on other sites More sharing options...
dannyredfan Posted May 8, 2022 Author Share Posted May 8, 2022 I have the plug, but there is a rubber piece that has a hole though it that sits on that plug. the problem iam having now it its not pumping fuel the pump has fuel to it. I didn't take the head assembly apart Quote Link to comment Share on other sites More sharing options...
Diesel Doctor Posted May 9, 2022 Share Posted May 9, 2022 A Roosa Master rebuild kit is great at furnishing all needed parts for a pump rebuild. If not in the kit, you will need to go see a pump shop. If not pumping fuel, have you cleaned out the return line? You need to be able to blow air from the return line on top of the pump and hear it return to the tank. (Remove the cap first) Best is to remove the return line at the tank and blow backwards without the pump hooked up. A plugged return will shut off a Roosa Master. If return is open, then you could have stuck pumping plungers. Work on the return issue first if not already done so. 1 1 Quote Link to comment Share on other sites More sharing options...
dannyredfan Posted May 11, 2022 Author Share Posted May 11, 2022 Well return line is clear. I just pulled the pump it’s going to a shop. Quote Link to comment Share on other sites More sharing options...
CIHTECH Posted May 11, 2022 Share Posted May 11, 2022 Do / did you have IH GSS 1010 manual? It breaks them down pretty good. Quote Link to comment Share on other sites More sharing options...
dannyredfan Posted May 11, 2022 Author Share Posted May 11, 2022 It seems the little rubber plug was replaced by a steel bushing. I put that in no change. Quote Link to comment Share on other sites More sharing options...
dannyredfan Posted May 11, 2022 Author Share Posted May 11, 2022 No I had the D manual. The wrong one. The guy iam taking it to does it on the side. Hopefully me and him can do it together so I can see what went wrong Quote Link to comment Share on other sites More sharing options...
Diesel Doctor Posted May 12, 2022 Share Posted May 12, 2022 Could be as simple as the cam ring or transfer pump cam ring in backwards. There is "C" marking for clockwise or "CC" for counter clockwise rotation. It has to be right. Quote Link to comment Share on other sites More sharing options...
dannyredfan Posted May 12, 2022 Author Share Posted May 12, 2022 Yea. That’s one of my thoughts Iam 98% sure I put it back just like it came out. Is it c or cc. Quote Link to comment Share on other sites More sharing options...

dannyredfan Posted May 19, 2022 Author Share Posted May 19, 2022 Well got it back from that guy. Still won't pump fuel. Is there a special way to bleed them. Had all the lines loose at the pump. I was told to bypass the filter. But I have a good flow though the filter pump is full. Idk what to do. Quote Link to comment Share on other sites More sharing options...
wendyoakscubs Posted May 19, 2022 Share Posted May 19, 2022 Not trying to be a smart a$$ but take it to a real pump shop who works on them every day. Depending on how busy they were it would have been running in a week's time. Maybe you don't have one local, but even an hour drive and back is still worth the peace of mind. My .02.

1958560 Posted May 19, 2022 Share Posted May 19, 2022 Dads 656 is hard to start if it runs out of fuel, even after bleeding air from filters and have a clear stream.at pump. We pull start it, sometimes takes a fair distance, but much better than grinding on the starter. My planter pump has a hard time displacing air in the system after winter, this may be no different Quote Link to comment Share on other sites More sharing options...
snoshoe Posted May 19, 2022 Share Posted May 19, 2022 Is the original problem cured? Did you try leaving side cover loose? Have you checked for transfer pump pressure? Did either of you inspect the delivery valve? Quote Link to comment Share on other sites More sharing options...
dannyredfan Posted May 19, 2022 Author Share Posted May 19, 2022 The guy I took it to used to rebuild them every day. But was in a wreck and is disabled now. I trust he knows what he is doing. But peace of mind is worth a lot. Yes the flex ring is replaced. I tried the inspection cover no luck. I haven’t ran it out of fuel yet lol. So maybe it is always this way. Plus it’s a hydro so I can’t pull start it 😔 Quote Link to comment Share on other sites More sharing options...
snoshoe Posted May 19, 2022 Share Posted May 19, 2022 Well are you going to give up? Are you going to check transfer pressure? You might ask him if he pulled delivery valve. Any fuel at lines at all? Quote Link to comment Share on other sites More sharing options...
dannyredfan Posted May 19, 2022 Author Share Posted May 19, 2022 Na I ain’t given up. I plan on checking transfer psi this evening. Injection lines are very loose on pump. No fuel there. We have not been in the delivery valves Quote Link to comment Share on other sites More sharing options...
dannyredfan Posted May 20, 2022 Author Share Posted May 20, 2022 Well it made a believer out of me! he told me to bypass the filter, make something to feed clean fuel straight to the pump ( what difference does it make where it comes from ) lol. but after trying it tonight, it worked. Best I can figure is if your tank is empty it actually lets the bypass through the return lines easier. so it primed faster disclaimer : my 656 doesn’t have a check valve on top of pump ( it’s supposed to ) That kept the tank fuel from back feeding the pump and air locking it. More or less. My best guess Quote Link to comment Share on other sites More sharing options...
