Oil Level 450C

Hartlyboy · Post by **Hartlyboy** » Thu Apr 17, 2008 3:42 pm

The spec sheet says a 450C engine takes 9 qts of oil with filter. Watching the dipstick on my first oil change I saw it go past what I believe is the full mark after I had added only 4 Qts. I figured the new filter would take up some of it and added a couple more qts. Now after a brief run-in , the oil level still shows well above the line with only 6 qts. Maybe I have a bogus dipstick in the engine. Mine is stamped AR69019 and the low level mark is about 1 1/4 inch from the tip. Next time one of you 450C guys pulls the dipstick, I'd appreciate knowing what numbers are on yours. The only technical help on the ground out here is a ways away and I'm more comfortable with the knowledge base I've seen on this website, anyway.

Thanks

hello, went out and checked my 450C, has the same dipstick number so u have the right one. i always fill my crankcase with a 5gal pail, so i cant tell u how much it takes.

Hi Hartlyboy,
I'm no expert! but two things come to mind 1 is the bottom of the oil pan pushed up? 2 Is the dipstick tube the correct length? Perhaps you could check with 430C and get a distance from the bottom of the block to the top of the tube?

Thanks for the responses. I know I have the right dipstick now and I have another thought to pursue about the length of the tube in the engine block. I think the bottom of the pan is OK since there is a heavy skid plate under there and it doesn't seem to be pushed in or anything. Just want to be sure the old girl has enough oil since it runs pretty good and holds good oil pressure.

If my dad doesnt take my 450C tomorrow i will measure the dipstick tube for ya. has your motor ever been replaced? i think there is a few different oil pans depending on what the engine is used for-tractor, skidder, power unit etc. might be the problem if its not the original.

the dip stick tube can be adj. to some degree 3/4 " wrench and yes they hold 9 qts those dip stick tubes are different lingth on different type machines as some one said--skidder--power plant--backhoe have fun Randy

Thanks for the info. I don't believe the engine has been changed , it has the numbers R550TT on the block , but someone told me that didn't make it a 550 engine. Dunno.

I also discovered some plug holes over the tracks that look to be where you put oil in the steering clutch wells. Amazing what you find when you knock all the mud off. Now all I have to do is take some of the overfill in the tranny out [I thought the tranny cavity was connected to the clutch wells, -apparently not] and put fresh oil in the clutches. Don't know if that will make it steer better but I'm hoping. Hope the old girl realizes all this messing around with her fluids is with her best interests at heart.

I also appreciate the radiator info/cooling system info I've found on this site. Am going to pull the instrument panel as part of the overall 'check it out and fix it up' process and the temp gauges will be prime targets. New rad cap and anti-freeze coming up, too. By the way, what ph should the cooling system be maintained at? The wrench turners around here think I'm being way overprotective, but as i say, you guys seem to know the low-down on these crawlers.

As far as I know - all the engine-blocks in 450B turbos, all 450Cs, and all 450Ds have casting #R122820

Wow, jdemaris, that makes the whole thing more interesting. I looked harder and the numbers are definitely R55011 on the top line and R55034 below it. Maybe that is why the 450c dipstick is giving me a strange reading on the oil. Anyone know if a 550 engine would normally be put into a 450C if re-powering?

I'll look around on the block to see if I can find the R122820 number. This number is on the right side to the rear and down about 2/3 way on the visible block.

I don't have any kind of comprehensive list of casting #s . In fact, I doubt even Deere Co. does. I keep my own records from many machines I've worked on and/or owned going back to the late 60s. With 450Cs - I haven't seen them all - but Deere lists only one block ever used in the series.

The number you cited does NOT seem to be a block number for a 550 crawler either. I do know this. The older 202 cubic inch engine used in early 450Bs has a casting # of 5400 and/or 5500 on it.

I'll also mention one other thing. Deere often has mutiple casting numbers on one engine. Seems that sometimes when a block gets revised, they add new numbers without deleting the older numbers - which is confusing.

One example is my Deere 300B with a 152 diesel. The block has three casting #s - 55100, 5510, and 55120
