131902020057A001 Idler wheel bracket Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

Short Description:

131902020057A001 Idler Wheel Bracket is important load‑bearing structural part of undercarriage for Sany SY1350C1C3KH large excavator. It is used for mounting idler wheel assembly, cooperates with tension cylinder to adjust track tension, bears impact load from track and restrict movement track of idler wheel to ensure smooth track operation and prevent derailment. Timely replacement shall be carried out when body crack, mounting‑base deformation, bolt‑hole tear and wear at idler‑mounting position occur, so as to avoid undercarriage travelling failure.

advantages

Integrally cast steel with quenching & tempering treatment, excellent impact‑resistance and compression‑resistance against repeated mine impact and resist fracture & deformation
Mounting holes and tension‑cylinder connecting holes strictly follow OEM dimension with good interchangeability, no on‑site cutting or grinding modification
Optimized force‑bearing structure disperses track impact load, reduces local stress concentration and delays bracket fatigue damage
High‑precision mounting reference surface ensures good coaxiality after idler‑wheel installation and mitigate uneven track wear.

FAQ

Q: Can slightly deformed bracket be reused after straightening and welding?
A: Straightening and welding will leave residual internal stress. Re‑crack risk is high under continuous mine impact and vibration, brand‑new bracket replacement is recommended.
Q: What should be checked firstly for track deviation after new bracket installation?
A: Inspect uncleaned foreign matters on mounting face, uneven bolt torque and assembly deviation of idler wheel & tension cylinder first, readjust track tension after troubleshooting.
