I probably should have said the clutch repair cost me a little over $1000 labor and machine work.  I had the clutch kit for over 5 years, it was about $300 back then..  The mechanic charges me $60/hr for labor in his own shop....  Very reasonable, here the dealerships are $125/hr.  Dealerships also do not like to work on 15yr old tractors.   The dealerships don't have many qualified mechanics as the oil patch is paying too much money for the dealeships to attract good help.

8345 has a new clutch.   The mechanic who repaired the clutch in my MTZ 1220.4 did the repair.  It cost more than the 1220, partly because it was not as clean I am sure, even though I spent 3 hours with the hot water pressure washer.  It really needed cleaning, and my detergent injector was not working.   The guy is very conscientious and I can trust him, so I am happy.  I was not looking forward to splitting that one by myself.   Maybe later when I get my shop cleaned out and my splitting stand loosened up, I still need to put a clutch in the 4010 and the 7030 Allis.  The Case 1270 is also leaking...

He took the flywheel to be resurfaced, I don't usually do that, but he insisted.  He said the machine shop spent about 3 times the normal surface time because the flywheel was so hard.  He said the pressure plate was just about gone, and there was a little wear on the flywheel, but no hot spots.  I replaced the disk with the one with the Ceramettalix buttons.  I have had the clutch kit here for almost 5 years. 

I knew it was getting weak, I had adjusted the clutch before we pushed posts in the last time building fence.  My New Holland with the left hand reverser is better for manuervability, but the loader is not as smooth when pushing down.  When a post hits a hard spot, the pressure will build up and then quickly shove it down sometimes bending a post.  it is a closed center pressure compensated load sensing system.   The 8345 with the open center system just pushes the post in!!!

 I had a David Brown many years ago in a rental service with a loader.  We went through clutches every month until I determined that the machine shop that resurfaced the flywheel had not resurfaced the bosses on the flywheel where the pressure plate mounted.  The perssure plate recessed into the flywheel.   When I put it on the lathe and turned the mounting down, the clutch lasted over a year, being used nearly every day cleaning up around apartments.

Just an update ...I got an email reply from MTZ parts.  They said that the single Belarus clutch does not use a pilot bearing.   Wow!!  After 50 years of working on trucks and tactors this will be my first clutch without a pilot bearing...

Does anyone have the part number or the bearing number for the pilot bearing on the 8345.  I have looked a three part manuals, and canot find the pilot bearing.   Looked in the engine section and the clutch section which is more gearbox than clutch...    The 8345 should be split next week.   Have a mechanic located in Western OK to do the work, I committed to helping a friend/neighbor build a pad and roadway for his new house, and he has offered to help me get my Cat 613 scraper runnign again.  Including mounting 4 new tires!!   So, I will take as many pictuers of the split 8345 and the 1220 he is working on now...

Just after I mounted the grapple on the loader, the clutch on the 8345 is on its last legs.  How did our other forum member fare on the 825 clutch repair.  I have the complete clutch, just lacking a clean concrete floor in the shop and a week of time.  I have splitting stands also, just need to have a week being relatively pain free and a helper.
