Re: Don\'t forget to torque those wheels!

More about the Green Machine than I care to read..... can you condense it down to a few words????? If Deere is one of them, then you only have to look for the other 19.... simple math.... 20 - 1 = 19.... LOL

Re: Don\'t forget to torque those wheels!

In the old days, we had 2wd tractors.

Now we have light-weight 4wd tractors.

When you make a corner, a couple wheels are trying to rotate forward faster than the other 2 wheels.

When you turn in the other direction, the pairs of wheels are wanting to push/pull in the other direction. You can see one wheel skid a bit when you turn real short.

What you don't see is the same skidding of the wheel rim inside your lug nuts.....

Repeat that a few 100,000 times on a lightweight rim with minimal lug nuts - and things are going to want to pull apart.

Re: Don\'t forget to torque those wheels!

it had never even occured to me that most of these tractors are 4 wd, that definatly puts alot more stress on the front lugs when turning, especialy with a loaded loader bucket. probably another reason it seems to be most common on compact tractors

Re: Don\'t forget to torque those wheels!

That was a nice waste of webspace Hickory. I found over 300 posts on this site alone regarding loose lugnuts on New Holland, Kubota, a fifth wheel trailer, Yanmar, Chinese tractors, this post started with a post on a JCB. I'm not going to waste the webspace here posting every post. You can go do a similiar search yourself if you don't believe me. Yes it happens with all makes and models.

Re: Don\'t forget to torque those wheels!

I haven't owned a Chyrsler product in years, so I don't know about now days. But many years ago all the left side nuts were backward, from the right. I guess it kept them from coming loose, or they wouldn't have done it. I don't know if they are still that way or not. But it shows it has always been a problem. It sure came as a surprise the first time you had a flat and had to take a left side wheel off. /forums/images/graemlins/smile.gif

Re: Don\'t forget to torque those wheels!

ford did that on a few trucks in the early 80s, i had just bought my 84 F350 and went to change the rear tires, this was about 3 years ago. i got th passenger side off fine, but the drivers side wouldnt budge, impact gun, big lug wrench, and i had just gotten a pipe to put on the lug wrench when i realized the lugs had an L stamped into the end, then a look at the threads confirmed that they were left handed. they came right off that way! i figured someone had put in the wrong lugs at one time, then a while later i purchased a spare rear end for my truck and it too was left hand, and i also found one other guy in town who had done the same as i till he realized they were left hand. pretty weird

WHEEL DISK TO AXLE BOLTS LOOSEN AND BREAK
Compact Utility Tractor
4200C( -426437), 4200H( -421852), 4200E(-429133),
4300C( -435497), 4300S( -437270), 4300H( -432548), 4300E(-439289),
4400S( -446531), 4400H( -441883), 4400E(-449424)
Complaint or Symptom:
Rear wheel disks to axle bolts loosen and
break on the following tire sizes:
11.2-24 4 PR R3 Rear Wheel
14-17.5 6 PR R4 Rear Wheel
11.2-24 4 PR R1 Rear Wheel
15-19.5 6 PR R4 Rear Wheel
12.4-24 6 PR R1 Rear Wheel
Problem:
1. Conical hub bolts loosen during forward
and reverse cycle or hillside operation.
2. Loose hub bolts allow disk holes to
wallow oblong.
3. Current countersunk holes in disk may
not provide adequate hub bolt mating
surface.
NOTE: Symptoms described above are for
the flat disk, not coined disk design.
Solution:
1. Check for stripped threads. Drill and
Helicoil axle tapped holes, if necessary.
2. Replace disk if holes are wallowed.
3. Replace all original hardware with new
bolt and flat washer to provide improved
clamping force.
4. Remove paint from the axle flange and
wheel bolt circle mating surfaces.
5. Replace wheels and tighten wheel to
axle bolts to 154 N • m (114 lb-ft).
6. Wheel bolts should be clean but not
oiled. Oil will decrease friction, allow
more torque and break the bolt.
Parts:
16-LVU12708 Bolt (Wheel to Axle)
16-24M7436 Washer (M14x32x4mm)
2-Wheel (See Parts Catalog)
Additional Information:
Check torque at 10 hour interval for the first
20 hours. Check torque often during the first
100 hours.

surface.

Solution:

As I thought thin metal. Lug nuts cannot grip properly if they don't have enough surface area.

I guess that all tractors that have thin metal wheels will have this problem.

Re: Don\'t forget to torque those wheels!

Therein lies the secret. Most tractor wheels do not have countersunk holes/lugnuts. If they do they are not deep/thick enough to hold properly. Auto/ truck wheels are either heavier or are stamped in a way that provides a deeper gripping surface. If not countersunk there is nothing but friction to keep the wheel snug on the hub.
