Thread Repair

[Stan's Cub]

I need to repair the threads in one of the holes that hold the draw bar in the forward position. one of these holes:
I noticed there are helicoil kits available but I don't know which one to get. here's a site with kits

thanks

The threads are 5/8-11. One of my tractors had bad threads at all the drawbar mounting holes. I measured carefully the layout of the 3 hole pattern and made a drill jig with "bushings" on each side of the jig so that it could be used at all 4 of the hole pattern locations on the final drives. Since it would be used only a few times, I used shaft collars for the bushings rather than coughing up big money for the hardened drill bushings. I carefully cleaned the bolt holes completely to the blind end of the holes and found enough good thread to use two bolts to hold the jig in place while I drilled the third. Then tap and install the insert. On to the next hole again using the jig bolted to the other two holes. It all turned out well.

thanks Bus Driver!

turns out my old boss at the trucking company has multiple helicoil kits including the one I need. just had to purchase the 21/32 drill bit for $26. Cub's in the garage waiting for me, just have to get a cup of coffee in me. a word of caution, please avoid walking into your moldboard plow, that piece that rolls the sod over is just about mid-shin height. looks like I have two knees on one leg!

OUCH!

I do feel your pain! Scotty is permantly my plowing Cub, and except for when he's working he wears a marker. This picture was taken last winter.

Ouch! That had to smart!

Excellent idea

We all take shortcuts thinking we will remember all the stuff that we need to remember including the dangerous stuff sticking out of our toolboxes, in the drawers, out of the trunk of the car and on the Cub. It is very painful to be reminded how much stuff we forget when all the rest of what we have to remember gets stuck into the mix.

This is brought home to me every time my shin makes contact with the hitch on the rear of my Grand Caravan. Talk about smart.... and I don't mean intelligence either... it hurts big time... and being a diabetic.. I don't heal so well, so I have these reminders on top of reminders for a long time.

I see that you have your trusty shop crane with the weight installation rig setup.... it amazes me the creativity that is in you..... I have to try to keep this in mind as we construct my new tractor house

I'm famous for bashing my shin on the tow-ball sticking out the back of my truck, so I bought one of those "Hitch-Halo"s they have at Harbor Freight, and it's saved my shins countless times.

Plus, I have the fun of making up really funny responses to the dozen people who ask me "what's that thing on your pickup hitch?" every month.

[Stan's Cub]

I don't dare leave the hitch in the receiver on the pickup just for that reason. I knew "exactly" where the plow was on the Cub, but didn't realize just how far that piece stuck out and I wasn't looking down 'cause I thought I was behind it, quickly learned I wasn't. no big deal, only banged it slightly today just when it wasn't bothering me, only hurts when I breathe. I did manage to get the helicoils in those implement bolt holes today. only was gonna do one but found two more that weren't 100% and figured I might as well since I had plenty of inserts. wasn't really difficult, just drilled in as far as possible without getting into final drive case and the inserts were just about the right length. hardest part was getting rid of that tang thingy. didn't have a punch or rod the right size so I had to grind down the smooth section of a 5/8 bolt until it was the right diameter to fit snuggly in helicoil. worked on one, the others didn't have enough space behind tang to snap it off so I resorted to a screwdriver. now all holes are in great shape. thanks for the help.

The old hitch ball in the shin trick... I ended up replacing the whole hitch to get mine out. Pulled a bunch of stumps with the pin out and it didnt budge. Rust is a powerful thing! The hitch was a deal (10,000 #) but had to drill new 5/8" holes in the frame.... that was a nasty job. Now I can put whatever I want in the hitch.... including an extension, a pintel, and the cool rack I got with the camper.

Don't leave it in there, after 10 years it will stick.

I can see where the plow would be too easy to run into!

Guess I am lucky that the holes in the finals and on the tractor seem to be in good shape. I did buy a 5/8" tap to chase the holes once I get done painting. Then again, they were well lubed and most were in use!
