Connecting Rod Boring
Connecting rod boring addresses the dimensions of a rod bore. Tell us which end needs work and the pin or bearing fit required for your build.
What this service addresses
A connecting rod interfaces with both the crankshaft and the piston pin. A request for boring must identify the bore involved and the intended components. Copper State Machine Shop offers connecting rod boring for engine builds and standalone parts work. Discuss the individual application and rod condition before planning work or buying related parts.
Before deciding on the work
- The end of the rod involved and the intended mating component determine the request.
- Existing dimensions, damage and previous machining affect whether the proposed bore work makes sense.
- Matching caps and the identity of individual rods matter when keeping parts together during a build.
What to bring or include
- The rods and matching caps, kept identified; specify the bore or end involved.
- Engine identification and information on intended pins, bearings or other mating components.
- Notes on damage, prior rod work and any measurements or component drawings you have.
Planning the job
- 01
Clarify which rod bore you want addressed and how the rod will be used.
- 02
Discuss existing condition and the dimensions required by the mating component.
- 03
Confirm which bores need machining and how the finished rods will fit the components in your build.
Connecting Rod Boring: common questions
What information helps define a rod boring job?
Tell us which rods need work, the bore involved and any wear or damage you have found. Include pin or bearing information so we can discuss the scope for your application.
Which end of the rod can I ask about?
Identify the end and intended component in the quote. The application and condition will determine the discussion.
Should I keep caps matched?
Yes. Keep each cap with its original rod and identify parts rather than mixing them during transport.
Do I need to bring piston-pin information?
For a pin-end request, include the pin or its component information. For other requests, identify the relevant mating parts.
