4. FAQ
Q: Which construction equipment can install the o-ring marked part number 8D-1642?
A: This 8D-1642 o-ring is a sealing component specially matched for the brake valve joint surface of wheel loaders.
Q: What seal category does spare part 8D-1642 fall into?
A: 8D-1642 is categorized as an o-ring, responsible for static sealing of the wheel loader brake valve mating face.
Q: What raw material is used to manufacture this o-ring?
A: It is made of nitrile rubber, which maintains stable elasticity and has fine resistance to brake fluid and hydraulic oil.
Q: What core function does this o-ring realize on the brake valve?
A: It isolates the internal oil passage to avoid fluid leakage and guarantee stable brake control pressure.
Q: Where is this o-ring embedded on the brake valve assembly?
A: It sits in the circular groove on the connection face between the brake valve body and cover.
Q: What factor will shorten the working lifespan of this brake valve o-ring?
A: Frequent brake operations and pressure shocks generated during loading work will accelerate wear.
Q: Can this o-ring keep reliable sealing under repeated brake pressure changes?
A: Yes, its rubber structure is designed to cope with frequent pressure fluctuation of brake circuits.
Q: What abnormal performance will appear once this o-ring loses sealing effect?
A: Brake pressure decline and slow brake response will occur when leakage happens at the valve joint.
Q: What inspection work should be carried out before installing this o-ring?
A: Check the mating surface carefully and wipe off sediment and metal debris in the sealing groove.
