A Guide to Changing Loader Tires Quickly

Front tires on loaders are often challenged by blowouts when working on rough construction sites, such as rocky surfaces. The risk of a blowout increases significantly as the front tire carries the load, steers and drives, and is the first to come into contact with foreign objects on the ground. In addition, the heavy weight of loader tires and the limitations of the operating environment and tools make replacing front tires a time-consuming and labor-intensive task. Especially for the unit that has many loaders and frequently works in the open air environment, this problem is especially prominent. After years of practical exploration, we have summarized a set of simple and fast front tire replacement method for loaders, the specific steps are as follows:

· Start the machine and prepare the space: first start the loader and find a relatively flat and open space. Raise the front wheels off the ground by operating the boom, then use a brace near the side of the blowout to firmly support the loader and ensure that the rear wheelhouse is properly wedged in (this process requires close cooperation with the driver to ensure safety).

· Removing the tire assembly: using a tool such as a pry bar, carefully remove the collar and locking ring and check the attachment of the tire liner to the rim. If the tire has been in use for a long time, the liner and rim edge may become sticky. To ensure safety, the machine may be moved slowly over short distances to help separate the liner from the rim, but turns or high speeds are strictly prohibited to prevent damage to the inner tube. Afterwards, re-support the front wheel to keep it stable.

· Inspect and clean the tire: mark the position of the inner tube relative to the outer tube, remove foreign objects from the tire and make any necessary repairs.
Remove the tire: using a tool such as a pry bar, gently remove the tire from the rim, taking care to protect the tire and surrounding components from damage.

· Evaluate the condition of the outer tire: if the outer tire is punctured by a thin foreign object such as a nail, but the surface wound is not obvious or small, the tire can still be used under low-speed operation of the loader (because it is a low-pressure tire). If the wound is large, it must be repaired to prevent increased damage to the inner tube during long-term operation.

· Prepare a new inner tube (if required): If replacing the inner tube with a new one, make sure that the bolts at the bottom of the valve are tightened to prevent air leakage. Remove any foreign matter from the inner lumen of the outer tube and sprinkle an appropriate amount of talcum powder evenly. After mounting the inner tube, properly inflate and insert the gasket to ensure a tight connection between the inner tube and outer tube.

· Mounting the tire: Re-mount the tire onto the rim and install the locking and retaining rings, taking care to protect the valve from damage during the process.

· Inflate: inflate the tire to the proper pressure using the on-board air compressor.

· Wrap-up: Press down on the arm lift lever and remove the bracket to complete the replacement. The whole process takes about 50 minutes.

For the rear tire replacement, another loader or other lifting equipment is needed to support the rear tire, and the rest of the procedure is the same as for the front tire replacement. Through this method, we can complete the replacement of loader tires efficiently and safely, effectively improving the operational efficiency.
