Case 646 Poor Condition, Whats it Worth

[oliver244]

I can't give very accurate information on the spot, but I can tell you the the K321 and K341 blocks are entirely different, the K341 has a much higher crankshaft height for example. Not sure how it compares to the CCKA. Nothing is impossible, given enough time and effort. I would suggest that the pto side of the K341 will not accept the standard pump mount as used on the GT's and 644. that bracket would have to be fabricated and the frame modified to get the crankshaft height correct. Also, the Kohlers used on the Case/Ingersoll models all were narrow blocks with the modified oil pan as designated by the "A" after the K321 etc. K341's were never offered that way so all have the 2 quart pan which gives you an even higher crankshaft position before even considering the taller block.

Bob I'm not familiar with the 18hp K361 and wonder if your thinking about it.
I have a k321 wide base block and a k341 narrow base block which is off my sons Wheel Horse C161. The WH C161 uses the narrow base block in a rubber bushing mounted cradle. Both blocks have the same crankshaft height and both were made in narrow and wide flange blocks.

The gray block is the K341 and the blackish block is the K321.

While were talking about blocks, does the Case hydraulic pump need the raised machined boss on the Output shaft side of the block?

This k321 block off a Power King uses the raised boss to locate the clutch housing. Regrettable its scrap as came to me with a thrown rod that took out the camshaft mounting tube part of the block

I am no expert on this , but here is what I have surmised . The raised boss is not actually raised , but rather the outer material is removed concentric with the crankshaft bearing bore to centre the pump bracket for alignment purposes. I have a couple of low hour generator blocks I am going to have machined . One for a Case and one for a old IH cub cadet . The Case block needs the boss and bolt holes for the small oil pan done . The Cub cadet just need the small oil pan bolts.

I am jumping in here. Sorry, I have not been around in a while.

I have a 646 that I got when I was just buried in other people's tractors. I drove it on the trailer, drove it off the trailer, and parked it about 5-7 years ago. What I remember the most about it is that the thing spun so freely by the starter. It would start, but it just did not seem to have any confidence. It was a deal where there was buying back a tractor that I had fixed up, and it was just a good running tractor, and it just came with a blower. The guy decided he had to go bigger because he lives in the snow belt in northern MI.

He offered me the tractor I fixed up for close to what I charged him and wanted me to also take the 646 he had that he was thinking about having me fix up until he decided to go bigger. I got both for $1,300. That was his price. I pretty much was driving the car to the trailer at that point. So, I quickly listed the tractor with the caster for $1,300, and a guy who also lived up in the snow belt bought it the day I listed it. So, the buyer picked up the tractor from the seller, to me, and paid him the $1,300. So, I looked at the guy who asked me to buy back his tractor and buy his loader with him, knowing that I was getting the loader for free, and I had to ask him if want some extra money now. He took $100 and was happy that the horse trading happened in one day. That was his goal when he called me.

He told me that the loader was tired. It seemed that way when I drove it a little.

But wait, there's more. The 646 does have a rusted bucket at the back where You left it outside and allowed water to fill the bucket. I was just thinking I would add some flat stock and burn some rods to build it back up. Shortly after this, another guy who knew me called and said he was switching his Case loader over to all quick-attach. I mean buckets and everything else. All he had was the original bucket. He said it was in great shape, and he would drop it off for $200. I said it sounds great.

At this time, I had a 644 that I rebuilt. I bought it for $500, and I worked very hard. I swapped the older 14hp Kohler to the newer one that had been rebuilt, and then I cannot remember what happened to that tractor, but it was expensive. I got that for $200, took the motor, and sold the rest for $200. After swapping the engines, I had the older-style one to get rid of, and I sold that for $200. I often wanted more power. I will soon see if the 648 I have will dig harder.

I still have a bucket that has some rust but is otherwise in great shape. I will get at least $400 for it. Just a front blade is more than $200.

During all this, I learned that some brand new CCK short blocks were being sold for $599 shipped. I called Boomer to help me pick the best one for the 646 and bought it. This means I should be close to having a 646 with a new short block with no money in it. I just do not know if I will be able to get all the gaskets and such from Boomer. He has told some that he is retired. We talked. He has some adjusting to do.

So, now I have a 648 with not too many hours on it. But it has some age and use issues that will be a separate thread. It is on jack stands right now.

I forgot the relevant close, so I got lucky a couple of times. The prices I got are not the normal prices, but I posted them so you can see what things can go for. I did pay $4,000 for the 648, and it has the 3-point, weight box, and rear PTO, the special valve that prevents the drop of the bucket or forks, and the forks attachment.

I am going to sell the stock fork attachment. I used the plans from the forum to build my own, and I have the sliding forks with the spring pin that I have 1" plus the pin size adjustability. That, too, is another story.

I sold the 644 for $3,500, but that was knowing that I had replaced all the worn items. The 644 was completely taken apart when I bought it. I had to fix it and put it back together. You know now that when I say that you can set a completely disassembled Case in front of me, I will fix it and put it back together from just a pile of parts. I had never even seen a loader in person at this point. So, If I tell you to download the parts manual, that is what I used to put a whole loader back together. I still do it that way today. I do a quick Google search, print what I need, and use them. Then, once I am done, the paper gets recycled.

I got kicked out of the Facebook groups because I told them to search for and print the parts manuals. I was told that was not helping. I did not give them the parts manual and explain how to do it. I have people paying me for that. I also may have made some people upset when they did absolutely nothing before posting for the first time in the Case group, wanting free instructions on how to fix their stuff. It actually was a blessing. These tractors are my puzzles. I learn about them. I find the why, before I fix the what is wrong. I was already giving more than I had the time for.
