Loose wheel bolts on JD 4400/help please

[mrcaptainbob]

Would Lock-Tight work? If it's a vibration thing, that should keep them in place.

I was at my dealer today to pick up some parts and the shop manager,stopped by and said hello and asked me about the wheels,and we talked a while,I told him I had fixed the problem or at least I thought I had it fixed,that was not good enough for him...he said they were going to figure out why the wheel bolts were coming loose and he and John Deere were going to fix it right,meaning a John Deere solution.I will wait and see,but I have to give this dealership an A+ for effort,from the recepionist clear through parts/service and sales have always been very cordial and friendly and honest with me and on the same token for all of the problems I have had,I never lost my cool with anyone and the shop manager even brought that to my attention,so.....anyway I still feel good about my tractor and John Deere and my friends at the dealer.Would I by another JD tractor....YES I would,I will keep you posted.

Just took delivery on 4410 with R4's. My rear wheels are bolted on with standard head M14 bolts with washers under the heads. But looking at a 4310 with R3's, the rear wheels were bolted on using tapered head bolts and no washers. And when I looked at my wheels, they have the tapered seats to allow the use of tapered head bolts.

I am wondering if there is any correlation between the type of bolt and the failures folks on TBN are experiencing?

They said they were the right bolts....Same as on the R-4s

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.
