Head Bolts

Postby Donaldj » Tue May 24, 2016 8:32 am

My 49 cub started blowing coolant out the stack when I started it one day. Checked the oil yes milky Managed to get the head bolts out without breaking,very happy. However I am not going to reuse these antiques checked out one of our suppliers and the bolts came to around 100 dollars thats fine. I dont know much about grades of bolts I sure it said grade 8 this morning I see A set of head bolts on ebay for 22 dollars doesnt say grade. What should I look for?

HamiltonBobsCubs is a Forum sponsor. There is a link to their website at the bottom of the page. I'd suggest giving them a call and ask about the grade. Otherwise, you can probably find them at a Fastenal or from McMaster-Carr. I think it's the short ones that are an odd length and you'll need to use a washer or shorten them about 1/8" to keep them from extending into the water jacket.

Those Grade 9 bolts are outstanding. I have had Grade 8 hit the yield point when torquing them and from that point forward I bought the 9's. Trim them as Bob mentioned. A couple of threads rusting in the water jacket will make for a nasty job for the next person. Seal the threads, I use Teflon paste, so coolant does not weep up the bolts in service.

I used grade 8's purchased from Tractor Supply when replacing the head on one of my Cubs. Also used a washer under the head bolt to shorten to the right length. Also as Jim said, used Teflon paste on the bolts. No leaks and she runs just fine now after a year and a half. Cannot remember what I paid for the bolts, but I think around $20 dollars.

A lock washer shouldn't be used when torquing a bolt.

I used grade 8s from.local farm supply store. I put a flat washer under all of em. No problems. Like said above I may have paid 20 dollars but not any more than that. I forgot to put sealer in the threads but I don't have any leaks so I'm not taking them out. Seems like I put some anti cease on the threads but don't remember now. I did put a tap through all of the bolt holes. Make sure the.threads are clean before putting head on.
