L54 grader blade question

Postby Jackman » Sat Oct 07, 2017 8:13 pm

On the plow lift mechanism the threaded rod that goes thru the spring has a large nut that I think preloads the spring , anyone know what size that nut is?
The nut is bigger than anything else on the CubImage

Mine is bigger than 1 and 1/16th , that's my biggest wrench I thinking 1 and 1/8 or 1 and 1/4 , going to Harbor freight hope to buy a single wrench instead of several its rare very rare for me to need big wrenches.

When you asked the size of the nut I gave you the thread size since you did not ask for the wrench size. Had you asked for the wrench size I could have gotten that also while I was in the shop.

Jackman, nuts and bolts are measured and specified by their diameter at the threaded area and not by the size of the wrench required to turn them.

If you don't use a large wrench often I would suggest an adjustable (or crescent style) wrench. If you ever need another large wrench and it's a different size, then it's back to buy another one, or just adjust the jaws on your adjustable wrench you now have in your toolbox.

Tried that, not enough room adjustable wrench on I about 1/16th room to turn, flip adjustable over and won't fit at all, and a pipe wrench not even close , a box end wrench should do the trick , thanks for the reply :D

When it comes to finding wrenches, especially large wrenches, without going broke, flea markets are your friend. With the exception of a couple of unique, oddball wrenches I seldom, if ever, pay more than $1-2 per wrench. Just avoid anything with "China" on it. :wink:

Try the pawn shops in your area. There's usually a good selection of end wrenches at local pawn shops around here.

Why do you HAVE to turn the nut? Ever worked on a Cub fan belt???? If your adjustable wrench will hold the nut, then turn the shaft.

I still don't get what is accomplished by tightening the spring? More down pressure? A bumpier ride? Less static cling? Whiter whites? :?

The nut needs to be tighten cause the spring is so loose that it spins easily , the rod when and if the blade hits an obstruction I believe is suppose to compress the spring and then go thru the hole in lower part of the lift mechanism, on my set up the rod does not go thru the hole when the spring is compressed the rod hits the mechanism without going thru the hole, if you look at the 1st pic I posted the rod is already in the hole , on my lift (the 2nd pic)the rod is at least 3/4 of an inch out of the hole .

BTW yes I've worked on a fan and lots and lots and lots (get the point :wink: ) of other stuff , more than likely if I hold the nut and turn the long shaft the rod will twist and snap off , not about static cling or whiter whites :x its about the wrench size needed to turn the nut :(

Harbor Freight is fine for wrenches that require incidental use. You can either continue to solicit the size here (which seems to be getting you only snarky replies at this point) or go out to your tractor with a tape measure and figure it out for yourself. I have an earlier version of the grader blade that does not have a down-pressure spring, otherwise I'd get the measurement for you.

Mine took a 1 1/4" open end. The bottom of the rod is about flush with the bottom of the bracket it goes through.
