Need 550 clutch hub spanner nut.

mechknit · May 29, 2020

I am going to get ugly in removal of my 550 clutch hub spanner nut. Last resort is using the ole air hammer to knock it off. But before I do this last ditch effort, I need to find a source for the nut.

(quoted from post at 08:36:17 05/29/20) I am going to get ugly in removal of my 550 clutch hub spanner nut. Last resort is using the ole air hammer to knock it off. But before I do this last ditch effort, I need to find a source for the nut.

Aren't these nuts staked? Did you drill it out? Or am I thinking of something else?

I drilled the stakes out. Tried tapping with a hammer and punch. Made THE tool. My half-inch breaker bar laughs at me. I have my small pipe wrench around shaft and wedged up underneath the steering gear(I have removed engine to replace it with a very low hour one, about 400 hours)I brought home my 3/4 drive set
and modified my tool to fit a 1 1/2 socket. I am going to give that a shot this weekend. It is a right-hand thread? I saw that somewhere on an Oliver
site. Any other ideas. I do not want to get too ugly for fear of not locating a new nut.

Should be right hand thread if I recall. You may just need a little heat or a 3/4" impact.

As for the nuts I believe Kent (SPMN) has them:

I’m guessing you’re talking about the pto clutch? I made this when I took mine apart. Had to get a helper to hold a big pipe wrench on the pto shaft and used a cheater pipe on the breaker bar but I finally won.

I made a spanner like that one, but after 1/2 drive breaker bar flexed too much, I modified it to handle a 3/4 breaker bar. This morning I am going to heat the nut a bit and try the 3/4.

mechknit · May 30, 2020

Nut came off. Heat and standing on a 3/4 breaker bar. Thank you all for the advice. I think the nut is salvageable. I have time, if I can get one, I will. I have messaged Kent but have not received anything back.

Hello Kent,
I went on instant messenger. I see you are also on an Oliver page of some sort. I did get the nut off eventually. I need to look at it closely to see if I should get another one. Might call you...
