rear lug nut torque

[Looking4new]

50 ftlb has gotta be wrong; even for fronts. I go 80 on the front lugs of the BX1500.

I thought 50 was a tad low. My Jeep gets 85lb/ft
I am glad that I got prodded to dig farther into the manual. Now I just have to get a torque multiplyer for my 1/2" torque wrench.

I'm totally confused about the offset plates. What are they?
Have we come to any conclusion on the rear lug torque values?

The "wheel" is not one piece. It consists of a rim and disk. It's the disk that bolts up to the axle studs. The disk (aka offset plate) is offset between the hub and the circumference where it bolts to lugs on the rim. These lugs aren't centered on the rim, either. So by "flipping: the rim and/or the disk, there are four different possible rear tire spacing distances. This could matter if a specific distance is needed between the rear wheels, like for rows of agricultural plantings, to maximize stability, or to fit througha doorway. The bolts that attach the rim and disk are farther from the axle so the stress is less as is the required torque.

Don't you guys take this the wrong way, because I don't mind jumping in here to help someone out...but....For about the same cost as 2.5 gallons of fuel...you can own a repair/service manual. Then you won't have to wait a day or two for the correct answer to your questions to pop up......Hill Billy Bob

Wow! are manuals so cheap (or fuel so expensive) for the Kioti's?
The shop manual for my M4700 now costs $126 (about 30 gallons of fuel), the parts manual costs $33 and the little owners manual costs $25.

But what can be worse is getting the WRONG info from us giving FREE advice. Thousands of $$ for a tractor, no money for how to put it together and take it apart is a false economy.

Or to fit on a trailer 78" wide between the fenders when the wheels are at 80" wide

My rim is one piece.

Have book in hand here Bob, problem being on page 10-14, book says 166.3 lbf-ft on page 50lbf-ft.

Actually you have an owner's manual, not a service manual, which is better than nothing, but, IMHO one ought to spring for a Kioti service manual for more available info and as a resource for their expensive tractor(s). They run +/- $100 - well worth it, in my personal experience.

I thought we all were refering to the owners manual that comes with the tractor.
I torqued the lugs to 50lbs, then upped it them to 65. Seemed pretty tight, I don't want to snap any. I guess maybe I should call Kioti and get an answer on this.

Chuck I can assure you that 65 lbs for the rears are no where near enough. You will "egg" out your wheel holes and ruin them here is snip from the CK35 workshop supplement. It shows a bit more. But common sense tells you that 65 lbs is not enough for those large wheels. After you torque them, check again in a few hours, and at 25 hours for several cycles to insure all the paint is wore in and the lugs have settled in.

Personally I would torque them to 160 lbs. I base this on other tractors I have owned of similar size and the torque specs in their books. It would be good to call Kioti and see what they say. The 200+ sounds excessive to me, but I can assure you 65 is no where near enough.

My rim is one piece.

Your photo from your owners' manual (http://www.tractorbynet.com/forums/kioti-owning-operating/312538-rear-lug-nut-torque.html#post3778017 shows 2-piece wheels for agricultural tires and solid (1-piece) wheels for turf and industrial tires. Apparently, you have the later.

Have you ever heard someone say it is not rocket science? Bolt torque has a few variables like grade of metal, size of bolt, size of nut or threaded material and dry or lubed. Plenty of torque charts out there. My JD owners manual that came with the tractor has a torque chart for bolts not explicitly listed so you know how tight to tighten that fender bolt or the bolt that attaches the cover to the transmission. What is apparent is some tractor manufacturers do not think the owners manual is that important otherwise they would get an experienced engineer fluent in English to proofread the document. Hopefully the service manual is accurate.
