have a D3C sittin for 16 years with the brake on. got the release pulled and it just stayed to the floor. sprayed the upper bat that holds them and the rod going back to the levers to the brake bands. The right one after some time pulling back seemed to move?? the left one was frozen fast took the pin out by the lever and banged on it. got it to move a little. Next the steering pedals you can push all the way to the floor with NO pressure at all on them. Once I do get it started will the hydraulic pressure push the steering pedals up or at least hane pedal pressure on them?
No they are spring returned. Start off taking all of the linkage apart, clean up and lube as you are now doing. In view of the idle time(16 yrs) take all of the pedal pivot shafts and bearings apart, clean and lube them. They have roller bearings that get full of dirt and rust. The springs that return the pedals are connected to the back end of the rods where they connect to the brake levers. Try not to change any rod lengths. Do the steering valve linkage aswell then take off the dog house and lever that goes into the clutch and brake. After that the internal linkage and levers can be worked on. Later Bob
I did forget to mention, the cat has a full enclosed cab. I can only see the linkage with a light. I guess the cab would have to come off.
here is a photo of it after 1 hr of cutting trees so I could get around to it.
Pretty good looking machine. I can't remember on those small machines if there is a floor plate to help with access. Setting for that long, I would want to manually turn the engine a couple of revolutions before using the starter. No telling if a critter got in through the exhaust pipe or rain water. Good luck and keep the pics coming.
Is this the one with the Japanese engine that no one can find?
It looks in amazing shape for sitting outside for 16 years. Why did it sit for so long? It's also odd it doesn't have a precleaner on the intake?
The pre cleaner was there as soon as I touched it it cracked in 10 pieces. Just put the top back on to keep out rain. The guy passed away 16 years ago and still there where he parked it. I check the oils and all fluids oil was 1 qt low. on the floor there are two filling tubes the front one was low 4 gallon. The rear was full. have to check the rear of the machine for Hyd fluid on monday. I did put a new 4d battery in but the starter brushes were all rusted which I posted in another thread. I will know Monday if she will start and move.. down the mountain and on the trailer.
Serial number plate..
16 years. Looks unbelievably clean for sitting outside that long. The hydraulic cylinders have no visible rust, they look like they were cycled yesterday. Not much tree gunk on the cab. Was the machine tarped or covered some way?
One trick I have used in the past on an engine that has been setting a long time is drain the oil & change filter . Head to the farm supply store and buy new pump up garden sprayer . Locate an oil galley plug on the engine block and make up needed fittings to adapt to the hose on the garden sprayer. Then use the garden sprayer to fill the engine with the proper amount of oil . This will help pre lube bearings and prime the oil pump . As mentioned bar engine over by hand first , hopefully it turns and no valves are stuck . Good luck with the D 3 dozer project .
It was covered in a heavy canvas tarp at some point, it was over the roof and hood it was all weather torn and soon at you touched it it ripped. Animals chewed the armrests apart but did not touch the seat at all. The rear sliding glass is smashed. ,Thats the only broken window in it. It would probably cost as much as the dozer to replace it. I did pump the tracks up and they both seem to hold well. Well monday it back up the mountain and install the starter. Talked to the local cat mechanic about it and he said the brakes are more than likely frozen to the drum. He said he seen many frozen from sitting with the brakes engaged. He said once you get it started let it warn up for 30 to 45 minutes. Then put it in 3rd gear and light throttle for 15 seconds, then 3rd reverse for 15 seconds. He said do the for 20 times and see if they com free. If not go to 2nd gear for 10 seconds and 2nd reverse for the same. he said try that for 20 times each way also. He said never more than 1/8 to 1/4 throttle. He said the last recourse is first gear 1/8 throttle only for only 5 seconds top. If the does not work let the transmission cool and start it all over again. He said he never had one that he could not get free. He said it could come free in 10 minutes or 5 hrs. but he said it will come free without and removal of the shoes or drum. He said just dont put it in first and gun it, then you will be replacing a lot of parts. I crossing my fingers he is right.
45V is a Japanese 3204; shouldn,t be anything unusual about that engine
Be sure to drain off any water in the lube compartments or worse if the water is froze don't start it until it is thawed out. Put enough power to the brakes and it will rip the linings off before coming unstuck or break something. Better to go in there and check it out.
Thanks Old Magnet, I would have to pull the cab off to get the inspection plate off. (so says the cat mechanic). Which I think he is right cannot find any panels to remove to get down to the brake plates. But going back monday and will look again, the weather is going to be better almost 50 degrees.
Well we got there Tuesday, Had to make a trip to tractor supply to get a 4 wheel wagon to pull everything we need up the mountain. Installed the starter, went back over all fluids crossed our fingers. with no starting fluid it fired on the second crank. No smoke or no blowby. It is leaking some oil from the front seal. The brakes are locked on will not move. Let it warm up for 1/2 hr. The controls for the transmission were frozen, had to take the front cover off and PB lube them and heat them with a map gas torch. Got the free in about 1 hr. Next was the blade control they too were all frozen, had to do the same. Got them free and went to angle the blade and the hoses blew. At least we had the blade in the air. Tried foward amd reverse no go. Played with it for about 1/2 hr and the left side broke free. Well at least I gould go in circles. Well 3 hrs later the right side did free it self. It was like a kid at christmas. It really felt good to see it move . Loaded everything up and headed down the mountain. I never owner a cat before or ever operated one either. Really cannot believe how easy it is to steer. Just touch either pedal and it goes the way you want. Will post some photos when I get it home..
very nice!
I stumbled on to this thread today. Congrats on the new/old little dozer. Could you even see the hour meter? Just curious how much it was ran. Looks like it could be a very fun project. Have fun and keep us posted..
Cool project I'd love to find something like that. How much did it set you back?
