Retorquing wheels

[BillyP]

Yeah - was a couple years back I think.

Thanks! I was almost certain I had seen them before

That's a good question...my wheels are welded which are which is what I've seen used with R-4 Industrial Tires
I'd guess your tires are Ag (R-1's) which have the built up wheels.
So, I don't know if you need to, but it sure can't help if you do. Maybe someone with Ag tire experience will chime in...

Update: I was looking at the pic of your new 790...
Anyway, if those nuts and bolts loosen, you'll see the paint chipping or loosening too, so, IMHO torquing the rim/center section fasteners probably isn't necessary. However, suggest you go by your manual.

Yup, I might see some paint moving on the bolt head side (outside). Side note - shows to go you what a great neighbor/mentor I have - I noticed, when we reconfig'ed the wheels, that since they were painted after the outer rim and dish were assembled, that the areas around the bolt heads, previously covered by the flanges of the dishes, were only primered. And with the reconfig, they were now exposed. I just made a side joke about it, and what did Danny do? Went over to his bench and grabbed a can of yellow spray paint, and painted 'em to match! But alas, since that's how we did the reconfig, the nut/thread side has disturbed paint anyway. Maybe I shoulda painted them when I had the chance.

Hm, the owner's manual mentions the torque of the lug bolts, but not the carriage bolts/nuts. Well, I'm supposed to be getting the service manual on CD this weekend, so I'll consult that.

but I put a witness mark[u/quote]

OK, but can't you lose some torqueness due to bolt stretch ?
Thus no moving marks ?

I'd say that would be negligible for most torquing we tractor owners would be exposed to.
It was never a subject in the aerospace applications I'm familar with.

However, the point of the witness marks is if the bolt or nut does loosen, those marks won't be aligned.

That CD is a great purchase!

Someone asked about 1/2 drive socket sets. You can get them pretty commonly up to 1-1/4 inch and if you know where to look you can get them up to 1-1/2. After that, going 3/4 is required. My set is 1/2 up to 1 1/4 then 3/4 for the 1 1/4 to 1-15/16. Tractors dictate some larger tools. And things like a smoke wrench for the really tough ones.

There is a Chinese import set sold under various names. Harbor Freight is one source. IT is 3/4 inch drive ratchet wrench and breaker bar and a set of sockets. I have had one for over 5 years and never a problem. I don't use them every week so if they aren't perfect quality like a daily use pro needs, so what.

I paid $39.95 at a FLAPS in San Diego but they are commonly available for about $50 and are worth it if you use them even once a year. I also have a 3/4 to 1/2 adaptor and vice versa.

I have a HF torque wrench (clicker type) that goes up to 600 lb-ft. I use it to torque my lug nuts which are specked at 450 lb-ft because most tire shops don't have a suitable torque wrench if they have one at all and some shops couldn't even take off my lugs that were at 450 lb-ft.

Just checked out the HarborFreight website... they look awesome. Great prices. I don't think that they will ship to Canada unfortunately but I will ask.

I don't know how far from the border you are but HF is a national chain (in the US) and might have a store near your POE. I have never researched international shipping BUT I recall the Tom Hanks movie that showed UPS to be global. Not sure about customs, duty, or the like but the quick glance I took at the UPS info on the net assures me you could get a UPS delivery arranged without too much hassle.

If the problem is that HF won't cooperate that is a larger issue.

Since we are talking about torquing can someone answer a dumb question. I was looking up a nut on my MMM in the manual to tell how much to torque it. It is the nut on top of the deck that surrounds the grease fitting. I measured the nut diameter (from outside edge to outside edge) and it was about 25-26mm. The largest one they list in their torque chart is 19-22mm. Am I measuring right? Am I supposed to be measuring the inside diameter? I'm a little lost here. I can't seem to match this nut up with one on the chart. Not only that but it seems to be bigger than the biggest one they list on the chart, but it is not the biggest nut on the deck by far.

You measure the diameter of the stud, not the nut.
