Front rims/lug bolts on 4115

We look forward to seeing the new rims too. Not fun to have the old ones split out like that.

I agree that the bolts were allowed to get loose too often and that you will be fine if you keep them tight. It is a poor design, not having studs and tapered holes. You want studs because it is common to remove the tire/rim and then put it back on but if you have bolts then you will eventually have problems with the threads in the hubs. With studs you just replace the studs and you're good to go.

the rims are supposed to be hubcentric(the center pilot hole fits tightly on the hub to carry the weight) and just use the lugs for rotational force and to retain the wheel. the tapered seat lugs are for lug centric (the lugs carry the weight) you might have difficulty using tapered seat lugs with the hubcentric wheels. if the holes in the rims aren't almost perfectly concentric with the pilot hole the tapered lugs could bind up and fail. there is also the possibility that the flange that the lugs thread into could fail due to the additional loading on them from the tapered lugs.

Well the wheels came in yesterday and I swapped the tires off and on today and got the wheels back on.

First 2 pics are of the the new left wheel with the original lug bolts and the original wheel that was on the left side:

Last two pics are the new wheel and tapered head 9/6-18x1-1/8 fine thread lug bolts with lock nuts on rear and original right wheel.

The new wheels are a different design than the ones I took off, they are stamped with more of a recess for the axle and of course don't have the taper a car wheel has, but like scrappy said,

"the rims are supposed to be hubcentric(the center pilot hole fits tightly on the hub to carry the weight) and just use the lugs for rotational force and to retain the wheel. the tapered seat lugs are for lug centric (the lugs carry the weight) you might have difficulty using tapered seat lugs with the hubcentric wheels. if the holes in the rims aren't almost perfectly concentric with the pilot hole the tapered lugs could bind up and fail. there is also the possibility that the flange that the lugs thread into could fail due to the additional loading on them from the tapered lugs."

The JD dealer explained it the same way and said the problem is due to not keeping the lug bolts tight. I have a lug wrench right next to where I park the unit to make sure we do not have a repeat problem.

I did put on the 242 loctite and used the crimp type lock nuts on the back side of the bolts. The tapered head on the lug bolts probably are not contributing much, so I am anxious to see if the lock nuts help. If these come loose I will be surprised, but we will see.

Last pics are of the newest addition, a Tilman 6x12 low profile dump with the 4115 inside. Chain locations are not optimum but will work until I install D-rings.

I am happy the 4115 fits inside the trailer. I went to the dealer with a Deckover dump in mind, but could not pass up on the deal he gave me on this trailer. I would have to buy an equipment trailer as well as the dump. Not optimum for hauling the 4115, but I really only haul it maybe once or twice a year. I have been borrowing a friends dump truck 5-10 times a year, so the dump trailer will be nice.

Those just look much better.
One way I keep track of lug bolts or stud nuts loosening is to put a small felt tip pen mark on the head and rim. That way just a glance will let you know if they have moved any.
Looks like you are good to go.
