Machine maintenance often requires servicing one or more systems of a mechanical device. This service may include, but is not limited to, repairing, cleaning, or replacing one or more features of these systems to increase the useful life of the machine, improve the efficiency of the machine, and generally enhance an operator's overall experience using the machine while the machine is in use. For example, an automotive vehicle undergoes routine maintenance of its lubrication system to extend the useful life of the vehicle. This maintenance typically involves draining used engine oil from the vehicle, removing a used oil filter, replacing the used oil filter with a new oil filter, refilling the engine with new oil, and appropriately disposing of the used filter and used engine oil. While maintenance is often scheduled for a predetermined interval of use, in other instances such maintenance may be unplanned or even unexpected depending on the operator's use and/or operational state of the vehicle.
When possible, engineers typically design a vehicle this service to be performed by a service technician, such as a mechanic, with relatively standardized tools for a given task. For example, engine fasteners selected from metric sizes may be removed relatively easily with common, complementary metric socket wrenches already available to most service technicians. Moreover, these socket wrenches have a particularly convenient size and shape to easily access and grip the fasteners during service.
In contrast, other service work may benefit from more specialized tools, such as filter wrenches for servicing hard-shell filters, including oil filters. In one example, a universal filter wrench configured to grip oil filters of varying size often has band, formed of flexible metal or fabric, that tightens around the oil filter until sufficient friction is generated between the band and the annular, hard-shell housing of the oil filter to enable the service technician to rotate the filter wrench and, in turn, rotate the oil filter for removal. Unfortunately, limited clearance around an oil filter in conjunction with a slippery, oil coated hard-shell housing often frustrates removal of the oil filter thereby increasing the time and cost of the labor to perform the service. In another example, a filter cap wrench specifically sized and shaped to complementary features on an end of an oil filter may be used to engage the oil filter and apply sufficient torque for removal. While less prone to slippage during removal, each filter cap wrench is specifically configured for use with a relatively limited number of oil filters such that a service technician working with many different vehicles may require many expensive and limited use filter cap wrenches, again increasing the cost to perform the service.
There is thus a need for a tool for removing hard-shell housing components, particularly a hard-shell housing filter, that addresses present challenges and characteristics such as those discussed above.

For clarity of disclosure, the terms “proximal” and “distal” are defined herein relative to a human or robotic operator of the tool assembly with the filter tool extending therefrom. The term “proximal” refers the position of an element closer to the human or robotic operator of the tool assembly and further away from the filter tool of the tool assembly. The term “distal” refers to the position of an element closer to the filter tool of the tool assembly and further away from the human or robotic operator of the tool assembly.
