Locking Caster With Insert 70360

The instructions say to block up the grill. However being I had everything removed from the grill ( propane tank, grate, tray, etc.) for a thorough cleaning, I just had my wife tilt the grill so that I could have access to the legs so as to replace the casters. With a rubber mallet gently hammered in the plastic inserts and then pushed in the casters by hand pressure.

The easiest way is to lay your grill on its back, then you can easily access the caster wheels. First disconnect the propane tank and remove it from the grill. Then remove the grilles, dripping pan, and everything that might fall off when you lay it on its back.
Once it's laying down remove the old caster wheels by simply wiggling it while pulling out steady. you don't need any tools. They will slowly but surely come off one by one. Then just push the new caster wheels in until they snap in place. And that's all :).

Removed old casters and replaced them with the new ones.

First one was most difficult. Once I figured best method for removal( tap screwdriver into collar seam with hammer), the other three went quickly. Installing new ones very easy.

Elevated one side of the grill at a time and knocked the old wheels off and replaced them with the new ones.

Put one end of the grill on a wooden block between the wheels. Grab the wheel from the underside so the wheel sticks out from the grill and hit it downwards with the rubber mallet to remove the old insert and wheel. Place the new insert in the frame and tap it into place. Insert the wheel and push till it clicks in place. Repeat for all wheels to be replaced.

Remove old insert, install the new insert , then press caster in the insert.

Everything went together just right.

Followed your video

Removed the grates, drip pans, and trap. Removed the old flavorizer bars and dials. Removed the two manifold cover screws, removed the cover. Removed the manifold bolt, and pulled the manifold away. Removed the old burner tubes. Cleaned the drip areas, installed new burner tubes, reinstalled manifold, manifold cover, dials, installed new flavorizer bars, reinstalled grates.
Tested burners. Worked like new.
Placed one side of grill on milk crate, pulled old casters, reinstalled new, and repeated process for other side.

1. Removed all movable parts, grills, grease pan, heat deflectors, gas tank, etc. from the grill so that grill could be put on its side, without parts falling our or moving - and to reduce the weight of the grill. Recommend that the top of the grill also be removed to make the grill lighter and easier to tilt the grill over on its side. (Top is easily removed by using pliers to remove to cotter pins and then pull the two pins.)

2. Tilt the grill 90 degrees onto its side so that wheels to be replaced are exposed.

3. Use a hammer/mallot and flat bladed screw driver to (gently) push out the wheel inserts.

4. Push in the new wheel insert and seat the insert with ballot. Then - insert the new
wheels. Lock the wheels so that grill will not roll as it is uprighted.

5. Upright the grill and re-install all moveable parts. 15 minutes total repair time at most.
