Will it FINALLY start!? Case 450B Dozer abandoned 15 years!

[@dieseJL]

Does anyone know why the left side track wouldn’t move!?!?

[@ianwille5780]

Seized track?

[@simonmusicka5552]

The track was seized as you could see the drive wheel was trying to turn the track I’ve seen it before the track was stuck she just needs a good run

[@ripstephenhawking8787]

Seized pins and rollers. No big issue. If you ever do another dozer that's sat awhile, a trick my pap used to use was a good doucheing of the track pins and rollers with used motor oil before even trying to start... by the time it busts off it had soaked in plenty. Kinda polluting though if you're not careful. Also....next time just crack all 4 injectors....lol

Right behind your left heel is a valve with the knob off of it with a round rod guard around it below thee seat. THAT valve is a declutch valve that you can move so that the particular track you're mashing the brake pedal will release so you can pedal steer the machine but will stay disengaged until you let up on the pedal. I always ran the 450's with that turned off so when I went to stop the track clutch would stay engaged and would stop the machine if both hi/lo levers were in high or low. You can turn the machine with one in high and the other in low 0r just put one in neutral and maybe use a brake. You need to know more just let me know. I ran one just like that, an 850 and an 1150. A Case is a Case and some are 4-letter words, just like Mack!

[@bigchuckyinkentucky6267]

The lever down on the inside of your left foot is high and low range. On mine you can only get it in gear with the engine off. Forward is low. Back is high and just for grading very loose, dry material on flat ground. As in no power. At least on mine. Which is a 450. No letter designation. The breaks on mine are dry disc and notorious for wearing out. I have actually removed the pedals to make room for my big feet. The dozer holds itself back on hills as long as the engine is running. If you keep the blade pointed down hill, which will also put gravity on your side for pushing, and the engine dies just drop the blade and it will dig in and stop you. If you are pointing up hill and the engine dies, the blade will slide on top of the ground and you are along for the ride. In seven years my breaks have never worked and I have only taken a few little roller coaster rides but I always have it in the back of my mind that someday I might have to just jump and stand there and wave goodbye.

[@dieseJL]

Forward is low? I thought forward was high?

[@bigchuckyinkentucky6267]

@@dieseJL As I said, mine is a straight 450 with no letter. It might have changed on latter models. And I can't swear that I haven't been running mine in the wrong gear for years. But mine didn't seem to have any power at all in the rear location.

[@thomaspetroff9117]

Nice job there fella's! The lower lever on the floor is Hi/Lo range back for low, forward for Hi. The L/R tower levers are Hi/Lo track drive Forward= Hi Back= Low Left brake was stuck because it turned loose in Rev. , Classic symptom for that brake system. When peddle is depressed it release the clutch for that side and applies the brake. That's the click you hear in the Trans. when applying the brake. The brakes are for piviot steering the track HI/Lo levers make gradual power turns. TGP

[@trajonduclos7931]

Good point about clutch release. I had forgotten!

[@ripstephenhawking8787]

Exactly right. 💯

[@dieseJL]

Ok so back is low? I see mixed reviews. To be honest for the 10 minutes I ran it I couldn’t really tell.

[@thomaspetroff9117]

@@dieseJL Correct 2 speed lever back for low range Means tower track levers in low = first gear. tower levers in high =3rd gear Shift two speed forward for High range, means tower levers now will be Low=2nd gear and High =4th gear. Never shift two speed lever moving, always stopped, and best to shut off engine, so it doesn't grind. TGP

So happy to see this thing moving! Well done! Just run it wide open and use the clutch to turn!

Think that is pretty awesome you are not afraid to throw down a challenge with that injection pump. I did the same thing with an automatic transmission and it feels good in the end that you didn't give up. Pretty cool too that you are out there to help the other guy that is struggling to figure something out.

[@dieseJL]

Thanks! It's too expensive to pay people to work on this stuff...

[@trajonduclos7931]

Great work guys! I have spent many hours operating a 450C. The controls were the same. Personally I love the two speed track. You will learn to steer with that system very quickly. Don't ever use the brakes. First of all they are useless, second they fail very quickly, third they provide very little advantage over a change in direction. Did I mention they're useless? Anyhow, enjoy your Case as I did. Also I believe your chain was rusted/ seized into a flat line on the bottom. Finally got some pins and bushings to wake up with force. Good luck.

[@dieseJL]

Yeah the power steer is verryyyyy nice

[@In2investing]

These old diesels are notoriously hard to prime if air gets in system. I've seen guys use a new style lift pump to the feed line just to prime for first start and it really helps. Once it's primed and runs they remove the lift pump, and yes crack all 4

[@michaelanthony3816]

All diesel systems are closed.put ALL lines on tight .just Crack the injected lines on top of pump till you see fuel dripping. Close lines when you have a good flow Crack ythe injector lines AT the injector 1 at a time until you have good flow this system is a Totally sealed system runs only when no air gets in.good luck

[@swotteh]

Fabulous! You guys ROCK & Roll!

[@danielboughton3624]

As others have noted you turn slowly with one track in neutral and fast with one in high and one in low. You also do not turn while pushing dirt since it is hard on the tractor and you don't have nearly the power when only one track is doing the pushing. The brakes on these are problematic and most guys disconnect them before they have to tear half the machine apart to deal with hassles. Mine were disabled when I got the tractor and I've left them that way. That said where I live it is flat as a pancake. You couldn't find something to roll down if you tried and the main issue would be running into a tree because you weren't paying attention.

The button on the side panel you said is hooked to the brakes is correct. It is a brake lock . It locks both brakes together , so doesn't matter which brake pedal you use it applies brakes to both tracks at same time. We had a 455C case crawler loader that had it .

[@ripstephenhawking8787]

In the future remember that every one of the screw on fuel filters before the injection pump has an air bleed screw as well.... and as I'm sure you can imagine, a filter full of air is one MASSIVE airlock! And will take FOREVER to prime without being bled.

I believe the brakes are out of adjustment your bull gears were trying but something stopped them when brakes act like after sprockets etc that is what it usually. Tracks are tightened by grease gat a manual, parts and assembly it would really help you Best of luck an d keep at it

[@DennisLDavis]

I have had a Case 450B for about 10 yrs-just like yours-Hi/Lo should be on decal on top of dash(I saw decal on yours - decal may not show on yours for hi/lo)lever forward is hi -lever back is low-most of the time I have to stop and kill engine and shift into hi or lo-on the fly sometimes will not engage(gears are not syc have to catch it just right). NO BIG DEAL. Always work or push in Lo with the two levers (between your legs) in back position or low-once you get some speed and load is lighter or moving backwards with blade up move two levers(together/at same time) forward to go faster. TURNING BRAKE PEDALS-AAhhh-they lock up rear brakes constantly!!! BAD design I think. Some people REMOVE the pedals altogether(if someone besides the owner is operating the unit and not aware of lock up) and steer with the two levers between your legs and forward/reverse lever. I never steer with tuning brake pedals. Raise the blade and try it in an open area, but always let off the gas pedal and let rpm come down(if you snap the trans main shaft lots of $$$$ will fly away) when you shift the levers-you will get the hang of it quickly. 3 functions of pedals(pushing both at same time and equal pressure) all way up-go - half way down -neutral(not moving forward or backwards) - all the way down - stop. Need to stop-drop the blade.LOL. One last thing(this is getting long) if you move the tall levers just slightly and not all the way to stop position while moving at a faster speed dozer will gradually turn in that direction(left lever drifts to the left rt lever to the rt) pretty cool!! About left track not moving - brake master cylinder stuck. If you want some more info and 1st hand experience - shoot me an [e-mail]. Have fun with that great little toy.

You could check fuel right into your bloodstream, holding your finger over the hole of the high-pressure pump good idea

[@landrelarose745]

How many years was that left track sized? It required quite an amount about playing with those levers to allow it to become freed. Congratulations on that. The save for allowing that engine to finally start. I'm so glad it did.

[@tedanderson463]

way back when I ran a TD 25 and it had a planetary drive associated with each steering clutch lever and you pull it back one notch and it would drop the gear ratio down 10 or 15% so that you push a full load of dirt in a circle and not have to keep starting and stopping and clutching and disengaging to get it to steer that's the theory full power to the track and make a right turn with no clutch slippage it's all done mechanically with gear ratios one track is going faster than the other... Another bit of information that might be useful to you is don't ever let a fuel tank get below one quarter full because it'll agitate the silt in the bottom of the tank and plug your filters up if you want to plug your filters up run that machine down so there's about two or three gallons left in the tank every time that fuel sloshes back and forth it's going to lift that silt and dirt and water and slosh it around and get it mixed in with the fuel but if it's a quarter or a half full it can't agitate like I said now if you want to get some of that silt and water out of there Park the machine so that it's leaning back a little bit and a little bit to the right and stick that siphon hose down inside there and maybe some of the silt will all go into one corner of the tank and suck it out into a glass jar one gallon pickle jar so you can take a look what's going on inside that tank there's usually rust particles paint chips dirt organic material water..

[@dieseJL]

That’s wild about the planetary. We have a TD8 that we redid the steering clutches in recently and I know what you’re talking about with the clutches but I don’t think it has the reduced speed option.

[@kevinroberts9394]

The brakes use hydraulic fluid not brake fluid. You do not need brakes to turn just run the side you want to turn to in low and the other in high. Our 450 had no brakes at all and the mechanic at ais said someone had put brake fluid in them. I believe if they do work they actually disable the drive as well as applying the brakes. I also think there is separate oil for torque converter but I may be thinking of the 580. It's been 20 years

[@dieseJL]

That’s interesting, I read dot3

[@davidpabis5428]

Only put a Case TCH equivalent oil in the brake master cylinders.

[@dansimpson6247]

sounds like its running better with more time on it, I think it may have had one or two cylinders with low compression but will recover with more run time. I think you may wish to look into adding more fuel if possible, it sounds a little poppy and hollow and isn't smoking at all under load? Maybe a slight timing adjustment with the pump may help as well although I think the timing is really close. Good job on the rebuild man it makes a lot of mechanically inclined people weary of messing with them and you took the challenge head on.

[@dieseJL]

Thanks! I think a few of the fuel lines still had some air in them too. I’m sure the more we run it the better it will get.
