I killed my payloader but good this morning

My 645 has really been one problem after another all fall and winter, and I thought I may have finally gotten the upper hand on it. But it told me different this morning. Was pushing some snow with it to try to find some bare ground to feed the cows on, and she let out a gut wrenching sound, quit moving, and now she has one bad hammering sound going on between the engine and transmission, whenever the engine is running. My guess is something in the torque converter area is in a very bad way. Scrap iron anybody. ...? Darrel

sometimes the worst sounds are the easy fixes .

IF you weren't so far away a 645 could have new owner .. liked the machines when I ran one

Coke, you saying that if I lived out near Minn/St Paul, I would be able to sell this pretty easily. .? Or you saying if I was close to you, you'd buy it. .? Either way, I guess it's kind of irrelevant, because it's not out there, my wife says it's not getting sold (she has a few dollars into it, also), and around here, I don't think I could give it away. If money wasn't an object, it would be in a shop already, getting a rebuilt transmission and engine. Rebuilt transmission is 7,500 bucks. And if Steve Fisher from Sleepy Eye would still have one of them government surplus 3500 engines for sale at 3,500 bucks, then 11 K would buy the two key components. I know there are lots and lots of other stuff that would add up fast, but even if a person got up into the 20 K range, and it lasted another 20 years, that'd only be a thousand bucks a year. Not bad for a good payloader. Darrel

Darrel. i looked a the parts book and its likely the flexible disks that couple the flywheel to the converter. From what i see the hydraulics would drive off the accessory gear on the back of the converter, so if they arnt working it might be as simple as pulling the engine and getting the new drive disks. Converter drive section starts on p. 73 if you dont have a paper copy

Was looking at couple posts on the machine - says the engine was the weak spot . Replacement engines installed and make good machines

I ran one for one summer a friend had bought it on a lease buyout .

Well after 22 months of ownership - he couldn't make last 2 payments and turned it back in - heck for the 2 payments left I could have owned it but he never offered

Hard now in this area to find anyone who even knows AC made construction equipment - only a few of us diehards that know any name other than CAT

Was a scrap yard in St Paul that was running 2 of them in yard - but place is gone now as well as loaders .

Cal, I was looking through my service manual, and I came to the same conclusion as you on the flex plate being the problem. Looks like pulling the engine and fixing it wouldn't be the end of the world. But I sure don't like the idea of pulling an engine and putting it back in when I know full well that the engine should get some attention that I can't afford before it goes back in. And since the engine would be out anyway, the transmission should be replaced at the same time. Darrel

Looks like our weather may be above 0 for at least the next 10 days, so I think I am going to pull the engine right where it died, and see what damage, or fix I can put to it. It would be tough to try to pull the big old gal anywhere due to the nature of the place where it died, and all of the snow around here. 185 should lift the engine right out. Darrel

You go for it Darrel while you have courage and motivation! The longer something like that is left the more will power it takes to get started.

I remember talking to a guy that bought a brand new 645...he was so impressed with it. When he knew I had a 745 he mentioned that there was a somewhat common challenge that used to occur to do with converter/ring gear/transmission drive on some 645's and I suppose the design would be the same on 545, 645 & 745 at the time. I never did find out the specifics but I wish I would have. This guy is dead and gone now but there has to be someone out there that has run into the same problem that could contribute helpful information.

according to my book,there are 3 flex drive disc plates(stacked together)that bolt to the flywheel and are bolted to the center portion of the converter.Probably broke something in there.Maybe after something (bolts)came loose?..or were not tightened by the PO?

Shameless...you got me thinking, couldn't you convert a combine into an awesome snowblower?? Don't know if you get snow where you live but Darrel could blow snow with it where he lives...now that his loader is down...

Good luck Darrel, keep plugging away and you will get it accomplished. Maybe you need to offer your son and his buddies some beverages to entice them to help you

You means like Coke or Mountain Dew, or Pepsi. Stuff like that. .? Darrel

More likely hot chocolate, with something else in it to make it smooth!
