I am looking at overhaul kits and I need to know if its standard compression or high compression. how do you know this? is a turbo charged high and a non turbo charged standard? any help with figuring this out would be appreciated. Thanks for all the advice so far.

Jim and bruce, thanks for the advice. I agree having the dozer is invaluable so I guess that answers my question.

So the mechanic removed the block and pulled the pistons. The sleeves were all ate up and pitted on one of the pistons. He then inspected the inside of the block and it had wear and pitting on the inside of the block on one of the cylinder walls. Yes,the coolant was leaking from sleeves/internally. ...

For some reason that link didn't work. what did you search and I will search it. thanks!

Hello all, I need some advice. I took my john deere 450c dozer over to my mechanic for a coolant in the oil issue and the final drives were filling up with fluid. he started with the engine.....the entire block needs replaced its ate up. Also, he measured the track wear and its at 120% worn. I need ...

Thanks Bruce. No i'm not sure its positive pressure. all I hear is air it is probably negative then. So does the vent tube come out after the screen is removed or is it apart of the screen? also, if you take the screen out could it be possible not to get it back in correctly? Also, i'm not able to d...

Hey all. I have a 450 C. some days it starts just fine and some times it won't start and just crank and crank and crank. when It won't start I bleed the fuel line at the injector. I loosen the nut and crank it until fuel starts spewing out and it starts. Then I tighten it back down and on I go..... ...

alright thanks for all the info. My next question is. if I split the track and dig into the final drive, what else should I go ahead and look at/replace? also, would you do both sides? Thanks!

alright so I am checking the right location. How big a deal in terms of stop everything and tear it down or do I have some operating time on it left? I guess what I am asking is can I operate it as is until fall or winter? thoughts?.... its just used on the farm I am currently using it to level a kn...

77 Ford- I am so thankful I upgraded the SALT tracks on my 450C to the two piece master links, b/c of situations like this and your comments, Bruce

- where did you go about getting you new tracks?

So I am checking the fill plug on the side of the final drive (back of the dozer) where the gear is. not on top of the track but behind the dozer. that's the final drive fill level correct? I could be wrong on this one.

Hey guys, I checked my final drive fluid and noticed it was above the fill plug on the left side. I drained it down to below the fill plug and went on about my business operating as normal. I did a cursory check the other day and found that the fluid was above the fill plug again. Where would this e...

Hey all - just wanted to thank everyone and let everyone know the outcome.

I had the radiator rebuilt and put it back in place. I ran the dozer for about 3 straight hours with no issues (normally by 15 minutes the coolant would spew out). I believe the issue has been solved. thanks again.

Should I flush the engine in any way? I used the little valve on the side of the engine to drain the coolant from the engine. should I push water through and let it drain? would that be beneficial at all?

Thanks for your thoughts.

my latest finding.... I removed the radiator tonight no problem. I decided I would replace the thermostat as well and removed the thermostat housing. when I removed the housing I found no thermostat. I know that's not a big deal. however the next thing I noticed was the line going from the thermosta...
