When I bought my 841, the 724 loader was on but didn't work because the engine wouldn't rev high enough. I removed the loader to split the tractor and just reinstalled the loader a few weeks ago.
I put five gallons of hyd oil into the loader (less than capacity) and was able to operate the loader, installing the bucket and moving stuff around on my property just fine. I worked with it for about an hour. The engine would bog down more when dropping the bucket than when lifting it, is that normal?
The last time I used it, I parked with the bucket in the air and later dropped it without the engine running. (I don't know if that matters.)
After that, this past weekend when I went to use it again, I could not raise the bucket. It lifted a little once or twice but there was rattling. In trying to figure out what was going on, I realized the drive shaft could move forward and back and kept slipping out of the engine end, and when secured in the engine, it appeared to barely reach the pump, causing the rattling.
I've looked at the loader and tractor parts manuals to see if there are obvious parts that could wear out and shorten the distance. There aren't, but I imagine that excessive wear on the gearing teeth could make the drive shaft more loose than it should be.
One of the things I did before giving up and dropping off the bucket was to fill the hyd oil to 13.5", which took about three gallons to do. Where the dipstick touched old oil, it was frothy. The bubbles tell me that there's still air in the lines, and if the oil was lower than the top of the filter, there's a chance air was being sucked into the system.
The drive shaft parts seem easy to find, but will that solve my problem?
The picture with yellow shows the pump mounted to the bracket and the shaft pulled forward onto the pump gear. The previous owner replaced the pump, I assume it's aftermarket.
The picture with red shows where the shaft meets the fan pulley.
Thank you for your insight!
