Thank you for confirming your serial number, which says it is a 1975 C series with a 6405 blade and you have the right manual. I usually ask serial numbers, as over the years many 450s have been mistakenly decaled as 450Cs and sold as such. Many folks only find out they don't have a C series when th...

As Labparamour mentioned. If you use hose on your pump suction line be sure you get/use a hose rated for oil service or you will be back there fixing it again sooner, rather than later. I think you are actually looking at the suction line going to the pump, the return is between the control valve an...

Welcome to the board. First question to me always for a "450C" is: What is the complete serial number to confirm it is truly a C series? There were 450 Cs and then there were 450Cs. Been down the road of trying to diagnose things only to find out it was the wrong C. 450 Cs and most 450Bs had dry clu...

If your blade is hydraulic lift with manual tilt and angle, it is a 6410 blade. The 6410 blade hydraulic lines, valves, and other components related to the blade are in parts catalog PC920. They did not start including the blades in the crawler catalog until the 450C model. If you don't have a copy ...

Your answer is in this post.

Welcome to the Board. Did you purchase a pdf copy of John Deere TM1033 or something else? It has the typical hydraulic system info. The copy of that technical manual I have shows circuits and has a good bit of info on the system and components for loaders and dozers. If you are looking for the manua...

If all the parts for the 440ICD are there why not rebuild it? Is the reverser still with it? That goes between the engine and transmission. You would still have your 440IC running to use while you do that. As noted the ICD used a heavier drive train, so to do it right, and expect it to last, you wou...

Welcome to the Board. Yes, the Web Links Board was the wrong place to post this. It will likely be moved to the Late Models Board when a moderator sees it. I don't know of a separate manual for the 3325 winch. The winch info, for the model winch the factory used on a machine, is usually included in ...

You say you have the engine free. Does that mean you have it so it turns over or does it mean it is running and are trying to turn the rest of the drive line under power. Just looking to clarify what you call free. I agree with Stan it sounds like you might just as well get going on pulling it apart...

I can't see your cylinder but it sounds like you have the type where the gland nut holds the gland (I think you may find this part called the rod guide in some manuals) out against that snap ring to remove any play and to keep the gland from moving into the barrel during operation. That internal sna...

boccop,

Just curious. What is the complete serial number of your 450? I'm just wondering if it is a straight 450 or a different series.

I would say it would be best to reseal them, the system is designed for them to be there. You might be able to cobble something together to bypass them but it could lead to other issues and it would likely steer harder.

Happy New Year to all!
Best wishes,

Welcome. The serial number/product identification number should be on the front panel of the battery box, right where you would see it as you get on the left side of the machine. The machine serial number is key, not the engine serial number (and there is no cross reference between those numbers). T...

Merry Christmas to all. It was looking good here, we had white on the ground yesterday. Today its 55, rain, heavy at times, along with strong gusting winds today. The 6 to 8" of snow, other than a few piles and packed spots, is gone already. Some mild to moderate areas of rivers flooding is expected...
