2305 governor linkage question

[mercdv]

ALL you really had to do was, pull the side cover..
Those little screws are TIGHT.. so a hand impact driver & a Phillips bit will get you in there..
THATS what the rack is turning, under the side cover.. control segments.. hooked to the pumping plungers..
The p. plungers are stuck from sitting, is my guess & all your doing is trying to break-up the varnished fuel..
Your just going about it from the "other" end..[gov] Lol.
Spraying pen. oil IN the fuel inlet & outlet will break up the varnish the fastest.. Just keep at it..
IF you applied TO MUCH force to the end of the rack, it IS possible to break off the teeth on the segments..
BUT just tapping on it w/ a plastic handle screwdriver wont do it.. so I think your good..

BTW> where are you located in SC?? I'm between Santee & Monks Corner.. IF your close enough I'll come give you a hand.

Ya know, I was wondering about that after I found the parts list last night. I assumed I wasn't supposed to take the side cover off since the screws are basically painted over. The parts list seems to show that the side access was for general maintenance like you are telling me now. I'm kind of intimidated by this pump because of all the warnings in the literature about screwing up timings, injectors, and operations. My specialty is computers not engines, can you tell?...lol. I'll get that cover off and attack it from that end now. Hopefully I didn't break anything already. Guess I'll find out when I remove the side cover.

Thanks for offering to help but you are about 4hrs from me.

Yea, 4 hrs IS abit of a drive, just for a cold beer.. lol.. cuz it would take me about 10 minutes to fix it..
I've done THAT ALOT on those pumps.. on the engine..
One of the most important things to know is> You HAVE TO USE a hand impact driver & hammer to get the screws loose.!!!
THEY WILL round off.. QUICK.. & your stuck chiseling them out.. & nobody got time for dat.. lol
Once your inside, its pretty self explanatory.. above the springs is a "segment".. the segment turns left & right.. inside the segment is the pumping plunger.. THAT is what pumps the fuel to the injectors.. it/they're stuck..
DO NOT loosen any screws on the segment.!!! OR stick your screwdriver between the 2 halves of the segment.. The screw holds the equal delivery to each cylinder.. & the segments are made of light metal.. to much force will snap'm like a twig.. so don't pry between'm.
You can spray you favorite penetrating oil inside the pump to help see.. it'll wash out.
BUMPING the engine to a different cylinders will speed up the process.. spray, move rack/segments/spray.. bump engine/spray/move segments.. bump engine.. & so forth..
REMOVE the lines AT THE INJECTOR.!!! BEFORE starting this process.!!
The LAST THING you want to happen is> the engine starting w/ a stuck rack in the WIDE OPEN position..
Removing the lines AT the injectors will guarantee that NO fuel will get injected into the cylinders & accidently start the motor..
HEED the warnings & follow the directions & your next post will be a happy one..
Good Luck.

Could you hear me cussing all the way on the other side of the state? I read this post after I attempted to remove the cover so needless to say it didn't go as I planned. I made the mistake of using a regular impact driver to try and remove them. Wish I had read this sooner because you weren't kidding when you said they round off quickly. Even on the very lowest setting it still rounded off the last two of them without even breaking them free. Ended up having to use some locking pliers to get them out. It's all good though because I hate phillips head screws. I know they are good for preventing over tightening and damage to the part but I don't like them on machine parts. I went out and got some different types to replace them.

On a positive note, I got the fuel rack moving freely. :applause: With your help, it took me about 30 minutes to get the thing freed up. I can see the score marks put on the pinions and the tappet assemblies at the factory and they are still lined up. Looks like I didn't knock any teeth off or knock them out of alignment. I'm hoping nothing is damaged internally. I'm going to let it sit over night soaking and start putting it back together tomorrow. I have to make a new gasket for the governor so not sure I'll get it all done tomorrow. My plan (if it runs) is to get everything all warmed up then change all the fluids. I'll let ya know if it is running again.

Thanks so much for the help!!!!

Yeah, they sure skimped on the "heat treat": on those screws.. ALL of them are soft.[more on the bottom]
SURE AM GLAD it worked out.. I hate to think my 30 years of inj. pump experience went to waste.. Lol
UNLESS you tore the gasket, reuse it.. its thick.. if it makes u feel better, smear alittle silicone on it.. A LITTLE..
Good Luck & keep us posted.. TPG

It's ALIVE!!! It's ALIVE!!! (Young Frankenstein reference, not the original. :laughing: ) I'm behind a few days because I went to town to buy supplies and completely forgot to buy the lock washers. Also, I decided to change the oil before starting it because the oil was charcoal black. After I got it all put back together, she started right up on first try. I still have to adjust the throttle cable, change out the coolant, change the transmission fluid, and fab a new battery holder (non-standard battery in it now).

I did end up replacing the gasket because the factory gasket had a portion that was hanging inside the governor housing and it got shredded. There was debris from it in the housing when I took it off. Plus, my dad always told me to replace everything that doesn't cost much when tearing something down just to be safe. I know it can be overkill but when pops says something I tend to follow it. He's got 75 years under his belt so I'm assuming his knowledge is way more than mine. He doesn't own a diesel so I wanted to let him rest and not ask him about all this.

Thanks for all the help...I think I'm going to put a fork in this one and call it solved. I GREATLY appreciate all the advice.

That is GREAT NEWS.. Always nice to hear a success story..
Thanks for posting the results & glad I could help.. but a cold beer woulda been nice. Lol
NOW YA KNOW, what not to do..
If your gonna store a diesel for more than a month>> TREAT THE FUEL..
Happy Tractoring.. TPG
