John deere 455 Questions

[dconrad246]

it has 1232 hrs. i bought it used from some guy in Missouri last year used. the problems have been showing up just as i tear into this thing to get it up to par. Rebuilt the whole deck last year then replaced a lot of the bearings to tighten up the aws. There seems to be no maintenance done on this thig from the previous owner once i noticed that after mowing once and noticing a lack of power compared to the 455 we owned 15 years ago i started digging. Changed ALL the fluids twice just to be sure (including filters) and that didn't seem to help with the slow seeming deck so i started looking into solutions and ended up starting this thread to try to figure it out.

When i did the valves i followed mmrbeefs vid on YouTube and haven't had any funny noises, fires or explosions, so i think i did it right. Also replaced the air filter when i changed the fluids the first time ( just got the home maint. kit.)

Based on what you said i am guessing its that idle screw, nothing else has helped so i am guessing its that. my only other concern is that the governor being turned all the way out isn't causing it to belch black smoke. Should it be? just doesn't seem right to me. Thanks for the help so far.

Sounds like great info.. thanks for contributing. Helps to add to this thread for others to know about along with the OP

After I get this problem figured out does anyone know how to find a cab for this thing? Have a few for sale around here but they are for a 400 tractor. Do they fit? Can they be made to fit? Got to figure out the engine issues first but that will be the next one to tackle.

Thanks beenthere.

Although I'm no expert, I would not expect the gov. adjustment to cause black smoke. Smoke is a symptom of unburned fuel, as you get when you load a diesel at wide open throttle, or if the intake is restricted. Your problem seems to be a lack of fuel, thus no smoke. Adjust the high idle screw and see if it addresses your problem.

I came here to answer your question, then saw the pics. What the heck is that???

This is what I was expecting...

Will do. I am going to have to turn that governor down if it works just so I can get the nut back on.

 

[dconrad246]

That fixed it. the pto is at 2010 rpm and the engine is at 3300. Thanks a million. Now to figure out a cab and heat.

 

[Dirtdobber1]

I'm glad that got you fixed. Good luck on the cab and heat.

 

[dconrad246]

any recommendations on a cab? i can get a cab for a 400 pretty cheap but I cant find a definite answer on weather it will fit or not.

 

[Dirtdobber1]

No recommendation from me. I simply don't know the answer.

 

[Kish318420]

If you're 455 has deck fender pan handle grips or the in fender tool box, I would say NO, those will interfere. The 400 cab has a very straight line for fit on the sides and back, the 455 has a slight curve, so if you try it, you may have to work on the lower edge sealing against the seat pan and the foot rest.

Oh forgot about the location of the fuel inlet also is in different spot.

 

[dconrad246]

Drats. will have to keep looking.

Here is a picture of my 430 with the cab on it.

See that looks like it would fit the 455. but anyway, another issue i have been having now that it is getting cold is it doesnt want to start. it will crank for days and puffs white/gray smoke till it fires then the usuall plume of black smoke. runs fine after that and antifreeze isnt low. Any ideas? have seafoam in it to clean the injectors but havent run it all through yet if thats it.

Do you know if the glow plugs are working?

 

[BravoXray]

I agree, you need to check the glow plugs. Either they aren't getting power, or they are bad. Had to change the ones in my 430 10-15 years ago. Still starts up as soon as the glow plug light on the dash goes out. If it's been getting progressively worse, my bet is on the glow plugs. BTDT.

Put new plugs in when I was adjusting the rpms. They were brand new ngks so I assume they are good. Wires are tight. I got into the habit of firing them twice when its below 30 out but still have the same problem.

 

[dconrad246]

How do I check if they are getting power. Guessing volt meter from the wire to ground. But just want to be sure.

 

[Kish318420]

Yes a Volt meter set to DC volts, you're looking for 12 Volts on each GP.

 

[Dirtdobber1]

Also check the ground straps from the engine to the frame. Probably good since the starter works fine but you never know.
