East Texas shop · Nationwide freight by quote · Visits by appointment
The equipment badge and engine identification answer different questions. Send both, especially if the engine has been changed before. A photo of the installed assembly helps show the mounting and accessory arrangement alongside the numbers.
Include the generator make, model, rated output, operating speed and whether it serves standby or regular duty. Identify the engine work you need and any known problems with the cooling, fuel or controls. Electrical and generator work must be scoped separately.
Tell us the machine model, what it does and whether you are sending a removed engine or a complete machine. Photograph the oil pan, drive end and accessory connections where practical. Confirm receiving and removal arrangements before moving equipment.
Ask which internal components and machining are included and which external components will transfer. The condition of the original engine and the parts needed determine the final rebuild scope. Core exchange, freight, completion timing and warranty belong in the written quote.

Review warranty information →The equipment brand is useful, but we also need the installed engine identification. Tell us about any previous engine replacement or conversion.
Call first with the engine identifiers, diagnosis and location. We confirm build acceptance, the assembly to send, loading and freight arrangements before it leaves your shop.
