98898
Linhai Evergrow
65565
In oil and gas drilling operations, the top drive system plays an important role in drilling, tripping, and well-control operations. Because top drives operate under demanding mechanical and hydraulic conditions, reliable spare parts are essential for maintaining equipment performance and reducing unexpected downtime.
· Product: Crank Assembly, IBOP
· OEM Reference: 98898
· Evergrow Part Number: 65565
· Application: TDS-11SA / TDS-9SA top drive systems
· Application Area: IBOP / top drive well-control equipment
· Supplier: Linhai Evergrow Petroleum Equipment Co., Ltd.
The 98898 crank assembly is included in Evergrow's range of replacement parts for NOV Varco TDS top drive systems.
The 98898 Crank Assembly is an IBOP-related mechanical component used within the top drive's well-control and actuation arrangement.
In the compatible top drive configuration, the crank assembly forms part of the mechanical linkage that transfers movement from the actuation system to the IBOP mechanism.
In practical terms, the crank assembly helps convert the movement generated by the actuation mechanism into the required mechanical movement of the IBOP operating components.
This makes the condition of the crank assembly important during routine inspection, maintenance, and overhaul of the top drive.
The TDS-11SA and TDS-9SA are established top drive models used in oil and gas drilling applications.
Evergrow's website lists OEM Ref. 98898 as a Crank Assembly, IBOP for these top drive spare-parts applications.
For customers maintaining these systems, correct identification of the crank assembly is important because the top drive contains many mechanically similar-looking components.
When requesting a quotation, customers should provide the OEM reference number whenever possible.

The IBOP is an important part of the internal well-control arrangement of a top drive.
The crank assembly works as part of the mechanical actuation system. When the IBOP operating mechanism is actuated, movement is transmitted through the associated linkage and crank components.
The basic mechanical sequence can be understood as:
Hydraulic Actuation System → Linkage → Crank Assembly → IBOP Operating Mechanism
The crank assembly therefore acts as an important mechanical connection between the actuation system and the IBOP.
The exact operating sequence and maintenance procedure should always follow the applicable equipment documentation and qualified maintenance procedures.
The IBOP is associated with well-control operations, making the condition of its operating components particularly important.
A crank assembly that has excessive wear, mechanical damage, or other serviceability issues may affect the proper operation of the associated IBOP mechanism.
For this reason, the 98898 Crank Assembly should be included in appropriate inspection and maintenance programs for compatible top drive equipment.
Potential inspection considerations may include:
· Mechanical wear
· Surface damage
· Deformation
· Cracks or abnormal conditions
· Wear at contact points
· Condition of associated pins and bearings
· Condition of the crank and linkage mechanism
· Evidence of abnormal movement
Inspection requirements should be determined by qualified personnel according to the equipment manufacturer's documentation and the drilling contractor's maintenance procedures.
There is no single replacement interval that applies to every drilling operation.
The service condition of a crank assembly can depend on factors such as:
· Operating hours
· Frequency of IBOP operation
· Drilling environment
· Mechanical loading
· Maintenance practices
· Lubrication and inspection
· General condition of the top drive
Replacement may be considered during:
During planned maintenance or inspection, the crank assembly can be checked for wear and damage.
During a major TDS-11SA or TDS-9SA overhaul, IBOP-related components may be inspected and replaced as necessary.
If the IBOP assembly is being repaired or serviced, the associated crank assembly and linkage should also be evaluated.
If inspection identifies excessive wear or damage, replacing the affected component can help restore the equipment to an appropriate service condition.
The crank assembly is only one component of the broader IBOP system.
Evergrow's TDS-11SA spare-parts range includes various related IBOP components, such as:
· IBOP Upper H2S Trim — OEM 110103-502
· IBOP Lower H2S Trim — OEM 114706-502
· IBOP Complete Upper Repair Kit — OEM 114859
· IBOP Complete Upper H2S Repair Kit — OEM 114860-2
· IBOP Complete Lower Repair Kit — OEM 99498-2
· IBOP Lower H2S Repair Kit — OEM 99503-2
· IBOP Actuator Shell — OEM 110042
· Crank, Oper-RH — OEM 110118
· Crank, Oper-LH — OEM 110128
· Seat/Ball Set — OEM 99500
These components appear together in Evergrow's existing IBOP spare-parts information for compatible TDS systems.
This makes the 98898 Crank Assembly a useful component to include when planning an IBOP maintenance or top drive overhaul spare-parts package.
Why Keep 98898 Crank Assembly Spare Parts in Stock?
For drilling contractors, top drive downtime can affect drilling schedules and maintenance costs.
Because the IBOP is an important part of the top drive's well-control equipment, having commonly required replacement components available can help maintenance teams respond more efficiently.
Keeping a 98898 Crank Assembly in stock can be particularly useful for:
· TDS-11SA top drive maintenance
· TDS-9SA top drive maintenance
· IBOP repair
· Preventive maintenance
· Top drive overhaul projects
· Emergency spare-parts requirements
· Onshore drilling rigs
· Offshore drilling equipment
Evergrow's website identifies the 98898 crank assembly among its TDS-11SA/9SA top drive spare parts.
When ordering a replacement crank assembly, correct part identification is important.
We recommend providing the following information:
