Wheeleez modification

I have found that the 10" wheels on my kayak dolly don't work very well on cobble and places like the put-in at Bullhead Flat -- China Beach. I replaced the 10" wheels with 13" ones from Harbor Freight. The axle required modification to 5/8". That can be done by using a 1/2"x7.5" bolt with a piece of 5/8" copper tube as the axle contact. The bolt slides into the existing tubular aluminum axle. The result is a much easier tow. Total cost = $32. See picture for tire size comparison. Contact me if you want details about the implementation.

Could you post part numbers

That’s a nice upgrade and I applaud the ingenuity. But sooner or later, you’d want to fish the salt and realize these wheels are ineffective on sand. There’s a reason people around here highly recommend Wheeleze or any dolly with balloon wheels, it’s a one and done deal. Might be pricey upfront, but it’s the last wheels you’ll ever use.

Correction....
Wheel Eez are not the only solution for salt anglers, but the best for long transport over soft sand. 
Case in point, I now fish exclusively salt, but rarely ever use my Wheel Eez as they are not necessary where I am.
Also,
It should be noted that Wheel Eez use a bushing instead of an actual bearing which will wear out quickly if pulled above walking speed. And the balloon wheels tend to hop when traveling over 5mph.
I AGREE that they are one of the best if not THE BEST option for soft sand, but don't confuse that with saltwater use.

Well, saltwater and sand kinda go hand in hand. There won’t always be a paved road that leads to the water everywhere you go. You will be challenged by different terrains the more places you explore, so why limit yourself? As far as towing, we’ve towed friends up the cove without a problem. But how often do we really do that and why push the capacity to the extreme?

I have needed the Wheeleez when fishing alone. In my uses it's always dirt, rocks and cobble.

For anyone who might be interested, here are the particulars:

Harbor Freight 13" pneumatic tires, 5/8" axle. $13.99. Item #67467
The rest of the components can be purchased at most hardware stores:
2 - 7 1/2"  x 1/2" galvanized or SS bolts with a long untreated shank
12" of 1/2" ID copper tube
4 large 1/2" washers

Remove existing wheels
Unbolt and remove the axle component from the Wheeleez
Remove and set aside the 2 black plastic  couplers
Trim the Wheeleez 3/4" aluminum axle ends by 2"
Cut off the bolt heads if you want easy tire removal in the future
Cut 2 pieces of the copper tube the width of the new tire bearing
Drill a cotter pin hole in each bolt end; Use the spring tension pins you took off the cart
Put together the bolt with cotter pin, 1 washer, the copper tube acting as another bearing, and a second washer
Slide the bolt with the components on it into the 9/16" hole in the exiting aluminum axle
If desired, rotate the bolt so the cutter pin is upright
Mark the new bolt axle through the existing vertical joint hole on the aluminum axle component; use a punch pin tool or a sharpie
Pull the new bolt axle and put a 1/4" hole at the mark
Reassemble the new axle/wheel components
Slide the plastic couplers back onto the Wheeleez shaft
Align the holes in the coupling, aluminum axle piece and the new bolt axle
Slide the fixed bolt which emerges from the bottom of the vertical Wheeleez part through the aligned holes and tighten down the nut
There is a small amount of play between the 9/16" ID of the aluminum axle shaft and the 1/2" bolt running into it
To eliminate the play, cut a 3" piece of unbraided 14-16 gauge wire, strip all bu the center 3/8", fold the wire at the middle of the remaining insulation leaving a gap of ~1/4", remove the tire and washers, depress the bolt axle to the bottom of the 9/16" hole, and press the U-shaped wire element into the gap. Tap the insulation into the gap. Reassemble the washer, copper sleeve, wheel, the 2nd washer and the cotter pin
I used heavy grease on all components to limit rusting.

Off road kayak cart! That thing will go over rocks with ease.

I used Wheelez on a gorilla cart bought from HD.  The front wheels also are mounted on casters, and the handle has a quick disconnect pin.  I can pull the cart with the handle or remove the handle and cart sides to transport a kayak or paddle board.  I then just steer from the front of the kayak without needing a handle because the front wheels caster.

Very clever work. Randy

Cool ATC (all terrain cart).

How prone are those tires to puncture?  They look like a thorn or sharp rock might be the end of them but I haven't had any experience with em.

Great ideas!
I've been wanting to figure a way to use my wheelers kayak carrier as a dollie for when at the beach with the kids.  Preferably a simple add / mod. to the stock yak kart.  Any one have any experiance or ideas?

Says the only guy on here that uses his atv to wheel his kayak to the sand/saltwater

I've used wheelez for over 20 years and never had any fail.  Pavement, rocks, and sand...no problems.  There is a way to repair a leak, but I've not had to do that.  They are actually much tougher than they look in a picture.

Curious ... was Wheeleez even around 20 years ago?

Also note, for a couple years, Wheeleez switched to different wheels, one with more tread.  They eventually recalled those due to excessive failure rates.  Although I never traded mine in, nor have I even had issues with them.
