Motor and hose to walk in order to prevent corrosion, reduce walking motor hose damage probability, reducing waste of hydraulic oil, improve the efficiency of maintenance, we decided to walk and hose hole area to the motor protection plate for containment, avoid mineral mud walking into the motor protection case, to achieve the purpose of protect walking motor and hose. Specific plan is as follows:

 

First of all, the guard pull down on the walking motor protection case, to guard appearance as a template, with 8 mm thick steel plate cutting out the guard ring.

 

Secondly, the retaining ring welding in walking motor protection case frame edge, clean with polishing machine grinding weld after welding slag, weld formation is bright and clean, again, using waste car tyre inner tubes, made two layers according to the outline of retaining ring gasket, adhesive and liner on the retaining ring.

 

Then, in the walking motor hose hole on foam sealant, the hose to the hole with all the space around the hole is sealed.

 

In the end, will walk clean inside the motor protection box, to show metal part besmear to brush paint, then walking motor protection baffle refitted.

 

Retaining ring and liner can walk well sealed motor protection box plate edge cracks. When pressure changes, due to the hose produces higher shrinkage and vibration, this should not take rigid seal. And plastic foam has certain elasticity, using it to block does not damage the hose. Aperture, around the foam rubber into rubber hose can have good sealing effect, at the same time provides convenience for maintenance work. Even if the hose aging need to change, remove the foam rubber is also very easy.
