RITO Travel Gearbox Shaft 720802 EX60 EX60-2 EX60-3 EX60-5 720802 Counter Shaft Secondary Shaft Excavator Secondary Shaft

Is an underperforming track drive transmission group cutting into your excavator's climbing torque or forcing your machine to drift constantly off-course? Worn counter gears and twisted gear teeth inside your reduction hub multiply internal friction, causing extreme heat generation and rapid bearing failure that can completely seize your final drive. Re-establish reliable undercarriage tractive power by swapping out lagging parts with the heavy-duty RITO 720802 travel gearbox shaft.

FAQ


Q: What mechanical warning signs point to immediate tooth wear or a bent structure along this final drive counter shaft?
A: Common indicators include tracking alignment drift when travelling straight, loud clicking or popping noises coming from the lower hub area, and heavy metal shards accumulating in the planetary gear oil drains.
 
Q: What installation checks are critical when sliding this secondary shaft assembly back into a compact final drive gear case?
A: Rebuild mechanics must carefully inspect the surrounding needle roller bearings, install fresh dynamic floating face seals, and ensure the shaft splines slide into the gear carrier hub smoothly without requiring forced hammer blows.
 
Q: Can parts distributors supply this 720802 counter shaft as a direct cross-match across different generations of the same excavator class?
A: Yes, this shaft matches the standard factory manufacturing blueprints for the EX60 model series from early dash-2 variants to later dash-5 versions, providing parts vendors with highly flexible stocking options.
 
Q: How does this transmission gear shaft avoid tooth fractures when the machine tracks over rough, uneven sand and gravel quarries?
A: The alloy steel shaft undergoes advanced deep case-hardening heat treatments, giving it a tough, shock-absorbing internal core with a hardened outer shell that resists snapping under sudden undercarriage impact feedback.
 

Q:  What quality options are available?

A: We provide original, OEM, and high-quality aftermarket versions with stable supply capability.
