Welded a nut to the reaming stem of the head bolt that broke off. It came out easily. When it comes to bolts, Would you get them from Kubota or source them locally as long as there in the same grades. What grade is a head bolt, grade 8? Metic goes by class so about 10.9?

Hokie's links are for the gear drive. If you have the HST version, then you want this one:

Get your head bolt from a dealer. Get the "Real McCoy"! Good that it came out easily.

Hokie,

No offense intended, but the links you provided are for the Intertec aftermarket manual. Kind of like a Clymers or Haynes. Part 1 is 18 pages, part 2 is 12 pages, part 3 is 16 pages. A total of 46 pages. The index in part 1 references up to page 100, so something is missing from the set.

The link I provided is the complete Kubota FSM for the HST version. 355 pages, all present. Plus I added bookmarks to each section. That's what I meant when I said "If you have the HST version, then you want this one".

Actually, peaking inside, I see that it actually includes the gear transmission too, and that the gear transmission is actually one of the sections missing from the Intertec manual, so I guess I should recommend it for all versions of the B6100 and B7100. Doesn't cover the B5100 though, so the Intertec manual is still necessary for that model.

Does the OP have any concern the two broken head bolts have compromised the head gasket or reduced it's life?

I can understand installing new bolts in the short run to verify the rest of the tractor is functional and worth further investment in time and equipment.

I have one head bolt broken #4. I have wondered that something had to have happened to break the bolt head off.

The compression test results would argue that the head gasket is intact. But it is an interesting question.

I wonder if it would be worthwhile to replace all the head bolts while you are at it in case whatever broke the first one weakened the others?

Good point - looking at the 3 part series, some great info and some not so great info - I down loaded your version again...only to find I had it already

Send me a PM and I'll send you a set of head bolts, I have an extra set here.
