Repair/Overhaul

The Ellison Throttle Body Injector has proven to be a reliable unit and should provide you with many years of trouble-free service however, as with most things mechanical, there comes a point when a unit should be disassembled, inspected, and critical components replaced.  While there are no set time limits for this service some guidelines include:  When the engine has reached it's rate TBO (Time Before Overhaul), after five calendar years of use, and/or if the unit exhibits non-standard operation. 

If you experience symptoms in the operation of your Ellison Throttle Body Injector that are not normal, or if you even have a question, please contact the factory for guidance on what to do.  Based on service repairs and customer support calls, we have identified some common symptoms of non-standard operating characteristics the Throttle Body can exhibit, which would indicate need for an inspection and overhaul.  these may include: 

*Excessively rich mixture

*Lean mixture

*Continuous and excessive fuel leakage after shut down (Contact factory for more details)

*Loose throttle or mixture connections

*In and Out end play of the metering tube assembly, with respect the throttle body housing

*Contamination of the fuel system

*Change in operating behavior of the unit

*Physical damage to the unit

If an Ellison Throttle Body has been sitting for an extended period of time with fuel in the system it may result in lean operation, in which case the unit will need to be returned to the factory.  Refer to the manual or contact the factory for proper purging instructions to remove all fuel from unit for storage.  Also, we do not recommend the use of auto fuel in the Ellison Throttle Body - A symptom of using auto fuel may be lean operation, especially at higher power settings. 

A typical overhaul starts with a visual inspection of the unit when it arrives at our repair facility.  We then determine what components and repairs are needed, perform the necessary work, and reassemble the unit.  The unit is then recalibrated to new specifications.  Typically the overhaul runs between 2 and 5 hours of shop labor, plus parts, however the cost can be higher if unusual damage is found on the unit.  To ensure a top quality repair we only provide service work on the Ellison Throttle Body Injectors at our factory, and we do not make parts available for customer repairs.  The typical lead time for a repair is 2 weeks, however this can vary depending on the number of units in house for service, please contact the factory for more information.
