226-4755 2264755 Crankshaft seal of MD5150C MD5125

Q: Which construction machine can part number 226-4755 o-ring be installed on?
A: The 226-4755 o-ring is a sealing component specially made for skid steer loader hydraulic manifold assemblies.

Q: What spare part category does the seal marked 226-4755 belong to?
A: 226-4755 is classified as an o-ring, used for static sealing of manifold joints on skid steer loaders.

Q: What core sealing task does this o-ring perform during equipment operation?
A: It prevents hydraulic oil leaking from manifold joints and stops external dirt from entering the internal oil circuit.

Q: Where is this o-ring generally mounted on the skid steer loader hydraulic manifold?
A: It sits in the sealing groove of the manifold port and gets clamped between the manifold and connector surface.

Q: What performance advantages does nitrile rubber bring for this o-ring?
A: It offers good elastic recovery and maintains stable sealing performance under frequent pressure fluctuations.

Q: What installation error will easily damage this o-ring?
A: Over-stretching the ring too much during assembly will cause permanent deformation and early leakage.

Q: What working condition will shorten its service life obviously?
A: Continuous high hydraulic pressure impact and oil with impurities will accelerate rubber wear and aging.

Q: How do maintenance staff judge this o-ring has failed?
A: Oil seepage at the manifold port and weakening of hydraulic power are common signs of seal damage.

Q: What small detail should we pay attention to during installation?
A: Keep the o-ring flat inside the groove and avoid twisting it before tightening the connecting fittings.
