Case 1845C

So I bought an 1845C last weekend, 3000 hours and guy claims it has never been used hard, only farm hours, ect ect ect. Took that with kinda a grain of salt, made a deal on the machine which looked clean and ended up bringing it home with me.

Put it in the shop and started maintenance on it and immediately thought to myself that the machine had been neglected. The pan underneath was literally full of rotten debris, several inches. Not that familiar with these but seems to me if it where being maintained that would not be like that.

Anyways changed oil, oil filter, flushed radiator, changed fluid, changed fuel filter and hydraulic filter and flushed and changed the final drive fluid. Greased everything.

Went out to use it today and I have zero hydraulics, most I could get it to do was roll the bucket. Then as I start back to the shop the left side drive seemed to want to hang up, almost like the break or something was on. Got it moving and now that side sounds like I'm running on tracks. Lots of chain noise......

Got it back in the shop, checked chains on that side and they appear okay. So now what....

Any help would be greatly appreciated!

As for the brakes, those machines used a pin system that hits a hole in the hub. Sometimes they don't retract correctly when you lift the lap bar if the springs are not clean and in good shape. You have to be careful with the brakes, if your parked on an incline example you should back up slightly to allow the pins to retract before moving forward. Otherwise the tires will stay locked, and if you push it, you can drive through the brakes which you dont want to do.

Yes definitely check the pin parking brake system. They are notorious for going bad and with a bunch of debris in the pan they may even be frozen. You'll find them under your feet, take that tray up and there's a pulley/cable system attached to the lap bar that pulls the pins in and out of the sprockets.

Also what kind of hydraulic oil did you use? Was everything working okay prior to you servicing the hydraulics? What are the temps like there?

Well I spent most of my Friday evening cleaning and spraying down with pb blaster the area around and those break cables and spools. They appear to be working and I've got the rest of the pine cones, pine needles, rocks, mulch and general crap out of the pan area up front. I am shocked this machine hasn't been on fire, with the amount of stuff I've pulled out of it.

Found grease fitting im sure have never had grease.....

Anyways I think my noise is slack in my chains. Manual says no more then half inch, I've got probably 2 inches on both sides. Going to try in get them tightened up tomorrow.

As for what I put in as far as hydraulic oil, case ih hytran oil from ag dealer ship. Only put in enough to top it off maybe a gallon.

Temps are cold, 20s or so but the loaders been in a heated shop so it shouldn't make that big of a deal I wouldn't think.

Loose chain might rattle a bit.
But if it sounds like you are running tracks, then it's your parking brake pins banging against the holes in the sprocket.
You need to adjust them so they fully retract when the seat bar is down.

And there are three chains in each chain box one for each wheel hub and one for the drive motor.

I'd jack it up and check for bad wheel bearings, just see if there is slop in them by rocking wheels back and forth.

As for they hydraulic problem I'd be checking the level after running for a few seconds. The same oil works the drive motors as the boom and bucket pump and you don't want to run either of those systems low on oil!

If memory serves me and it may not, I believe the hyd system calls for 10-30 and the HTO additive. I am sure that is not your issue, but may want to confirm what hyd fluid is called for.

Well many hours spent today and I have confirmed all my chains where out of adjust, some worse the others.

Bearings all seem good.

Parking brake cables literally had so much debris around them I cant think they were even working at all. Cleaned them all off and went to adjust and get them freed up and found out the one side had already broke in at where the cable bolt fits into the actual pin that locks into the sprocket used for the brake. I cant see anything down into chain case that would be a problem but I figure I better get in there, drain those tanks (again) and try in clean them out to be safe. I dont think anything harmful would have gotten in but 10 quarts of oil are cheaper then taking a chance.

Ordering break cable Monday and praying we can get her all back together and running as it should.

Oh and the hydraulic issue was in the linkage. Was out of adjustment and I guess by us greasing, cleaning ect it was enough to throw it out of whack.

Anyways thanks for the info, all good stuff and it all helped me today.
