Crown RR5700:
Swapping load wheel

Any advice would be much appreciated I am having a difficult time figuring out how to swap out load wheels. Which would be the two small front wheels in front of the forklifts not the back wheels. I see that there is a pin on the outer trigger ends.

Unplug the battery
Get it inside (if not done already)
Pull the top cover off
Get a hair dryer and get busy drying out the electronics, control handle and anything else that got wet.
And hopefully it will come back without any issues

Good luck

if your speaking of the outrigger loadwheels they are fairly easy to change.
One important note about replacing load wheels, they have to be replaced in pairs if there is much wear on them. This has to do with level and stablility of the lift so it is a good practice to do.
Replacing just one side or just a front or back wheel will cause uneven travel or uneven pressure on the loadwheel assy and only one wheel in the pair will touch the ground.

Most of the time i just replace them all so there will be no problems.

Removing the Wheels
- you will need to get a forklift jack that will fit underneath the outrigger or the side of the lift so you can jack up that side of the lift to get the wheels off the floor.
- Have some blocks ready and set the outrigger down on top of the blocks to stablize the lift.
- Once you have the lift wheels raised off the floor and stablized then you can drive out the roll pin.
- This pin is usually a roll pin recessed inside a groove on the side of the outrigger leg where the axle pin is. Make sure you use the same size roll pin driver tool so you will not damage the hole in the axle.
- Once you get the roll pin removed use a brass punch or rod to drive the axle out.
- Once the axle is removed the wheels should drop down, you can then pull them out of the outrigger.
- Pay attention to each side of the wheel because they usually have washers or shims or both so make sure you keep track of them and how they are placed inside each side.

- Clean the parts up.

- You can drive the bearings out of the wheels and try to reuse them but if they have excessive play or the seals are damaged you should probably replace the bearings, check the washers or shims also and replace if they are worn any.

- Driving the bearings back into the new wheels, make sure you press them in using a press or if you want to do it the old school way and drive them in using a hammer and a flat steel plate just make sure they go in straight not damaging the inside of the wheel. a press usually works best

Reinstalling the Wheels
- After you get the bearings in then reassemble in the reverse of how you took the wheels out.
- You may want to replace the roll pin with a new one, old ones do not stay in very well because they are already been compressed.

- Both sides should come apart and go back together the same way.
- Once you complete replacing the wheels jack the truck up, remove the chock block and lower the lift back to the floor.

Then use a grease gun and grease them, although you should pack the bearings before installing them you still need to put more grease in after installing to fill the cavity inside the axle area. Just be aware how much you put in and do not let it come squirting out past the seals, this will cause the bearing seals to pop out and at that point they do not serve their purpose of keeping grease in and dirt out.

If you have any other questions feel free to post them.
