I am working or replacing the pro clutch discs and seals of a 550. I have split the tractor and remove all the pto parts down to the spider hub and dreaded spanner nut. This is where I am having my problem. How do I get the spanner nut off?
I have tried the following: beating the nut with a hammer and wedge; using a pipe wrench on a spanner wrench made out of 2" pipe with 4 tabs welded to the end; added a impact socket to the end of my spanner wrench to use a impact gun; and generally just heating, beating, cursing and repeating. All to no avail. Any other suggestions?
A couple of things I have noticed. To keep the hub from turning, I have been using a scratch awl to put in a hole on the outside of the hub. At least until I sheared off the awl will trying to turn the my spanner wrench with the pipe wrench. How should I keep the spider hub from turning while trying to remove the nut? Second I have been using a propane torch to heat the nut, so far it is not helping. I read where one guy used MAP gas. What are your feelings on using MAP gas? Finally, if I destroy the spanner nut, can I get a replacement?
Thanks
