An oil change cap and system are described. A removable oil cap kit includes a removable oil cap and an oil retention bag. The removable oil cap incudes a sidewall and an interior surface, the interior surface has an opening extending therethrough. The sidewall includes an inner portion and an outer portion. The outer portion of the sidewall includes a channel formed therein for retaining an oil retention bag. The inner portion of the sidewall includes one or more protrusions to couple the removable oil cap with the oil receptacle of a motor.

A service tool is designed for releasable coupling to a service port receiver connected to a service port associated with a gearbox. The service tool includes a coupling arrangement for releasably coupling to the service port receiver. The coupling arrangement is configured for rotational movement about the said receiver between a released position and an engaged position. A locking actuator is operatively coupled to the coupling arrangement and arranged for axial movement between a locked position and an unlocked position relative to the service port receiver. A plunger actuator is adapted for connection to the fluid conduit, which plunger actuator is slidably coupled to the coupling arrangement for movement between open and closed positions. In the open position, with the coupling arrangement in the engaged position and the locking actuator in the locked position, the plunger actuator is adapted to contact a check valve of the service port receiver and open it to permit fluid flow between the gearbox and the fluid conduit via a fluid pathway formed at least in part by the plunger actuator.

An engine assembly includes a small air-cooled engine and a dry sump lubrication system including an external oil reservoir, wherein the dry sump lubrication system has an overall oil capacity that provides at least five hundred hours of engine oil life.

The application relates to a venting cap for oil tanks of machines and machinery, including: a cup fitted with a flange along its outer surface, with this flange bearing coupling elements underneath it with complementary elements provided on the access sleeve of the tanks and at the top of shaped engagement tabs, a lid for closing the cup that is snap-fitted onto the cup, fitted with a flange, wherein: the flanged partition houses on its lower surface an insert with a substantially cylindrical profile, the cup body is associated with a spiral labyrinth on top of which is fitted the means for engaging the cup; and above the flange of the cup there is a collar fitted with an external toroidal groove that engages with a raised toroidal thread along the inner surface of an upper closing lid of the cup.

An engine assembly includes a small air-cooled engine and a dry sump lubrication system including an external oil reservoir, wherein the dry sump lubrication system has an overall oil capacity that provides at least five hundred hours of engine oil life.

An oil filling device is provided, including: a main body, configured to cover an open end portion of an oil pot, including at least one first sliding portion and a channel; a control member, rotatably disposed on the main body; two clamping members, at least one of the two clamping members including a second sliding portion slidably mounted to the at least one first sliding portion; at least one guiding unit, each of the at least one guiding unit including a guiding groove and an assembly portion; at least one positioning member, connected to the assembly portion and slidably disposed within the guiding groove, wherein rotation of the control member operates to control at least one of the two clamping members to move relative to the main body so that the two clamping members relatively approach to or distance away from each other.

Apparatuses are disclosed including an apparatus for machine fluid monitoring or sampling comprising a transparent sight glass attachable to a machine such that machine fluid is transferable to the sight glass. The sight glass is at least partially constructed of one or more materials that is transparent to light in a visible region. The sight glass has an open first end, a closed second end, an inside surface and an outside surface extending from the open first end to the closed second end and across the closed second end, the sight glass at least partially surrounds a cavity within the sight glass, the inside surface and the outside surface of the closed second end being parallel. The closed second end is constructed of the one or more materials that are transparent to light in the visible region to allow inspection of machine fluid through the closed second end.

A lubricant filler for a lubricant tank of an aircraft engine comprises a filler tube having an upper portion to be disposed outside the volume of the tank and a lower portion to be disposed inside the volume. First and second openings are respectively provided in the upper and lower portions. An oil volume sensor is received in the filler tube through the first opening. A valve is connected to the filler tube and movable between an open position in which the valve provides a fluid connection into the lower portion via the second opening, and a closed position in which the valve blocks the fluid connection into the lower portion via the second opening. A third opening, smaller than both the first and second openings, defined one of: a) through a sidewall of the lower portion of the filler tube to provide a fluid connection between the volume and the lower portion when the lubricant filler assembly is attached to the lubricant tank, and b) through the valve to provide the fluid connection when the lubricant filler assembly is attached to the lubricant tank.

A method of monitoring the usage of an internal combustion engine comprises performing an engine monitoring routine using a local monitoring device attached to an internal combustion engine. The engine monitoring routine includes generating data representative of a plurality of vibrations of an internal combustion engine using a vibration sensor of the local monitoring device, processing the generated data to determine a first value representative of a firing frequency of the internal combustion engine, generating an aggregated summary based on the first value and transmitting the aggregated summary and identification data for the local monitoring device to a remote application. The remote application processes the transmitted aggregated summary based on the identification data to determine engine speed usage data.

An engine oil tiller cap for monitoring an internal combustion engine comprises: a processor; and a sensor module comprising a pressure sensor configured to sense crankcase pressure of the internal combustion engine and to output data representative of the sensed crankcase pressure to the processor. The engine oil filler cap is configured to provide a housing for the processor. The processor is configured to determine a value representative of the firing frequency of the internal combustion engine based on the output data.
