Mobile Line Boring & On-Site Machining Service
Blake’s Repair Service brings precision line boring and on‑site machining to heavy equipment across Maryland, Virginia, Washington D.C., and Southern Pennsylvania. Worn, damaged, or oversized bores can affect the fit and function of pins, bushings, and pivoting components. Our mobile line boring service allows us to restore bores directly at your equipment location whenever the application is suitable for on‑site machining.
- On site line boring and machining available.
- Heavy equipment and excavator line boring
- We can repair bore diameters 1½” to 12″, with larger sizes available upon request and longer lead time.
- We can rebuild your Construction, Industrial, Marine, Manufacturing Equipment to O.E. Specs.
What Is Heavy Equipment Line Boring?
Line boring is a precision machining process used to restore worn, damaged or misaligned bores in heavy equipment and machinery.
Over time, repeated movement between pins and bushings can wear the surrounding bore. A bore may become oversized, elongated or out of round, affecting the fit and alignment of the components.
Depending on the condition of the bore, the repair may involve weld buildup followed by precision machining to restore the bore to the required size and specifications.
Excavator Line Boring
Excavators rely on multiple pinned joints and pivot points that experience significant wear during normal operation. When a bore becomes worn, simply replacing a pin or bushing may not correct the underlying problem.
We provide line boring and bore repair for components such as:
- Excavator booms
- Boom-foot bores
- Sticks and dipper arms
- Buckets and bucket ears
- Hydraulic cylinder mounts
- Linkages
- Pivot points
- Attachments and pinned connections
Line Boring for Construction & Heavy Equipment
Our mobile machining services can be used to repair a variety of heavy equipment, including:
- Excavators
- Booms, sticks, buckets, linkages and pivot points
- Wheel Loaders
- Loader arms, bucket connections, linkage and pivot bores.
- Backhoes
- Loader and backhoe linkage, pivot points and attachments.
- Bulldozers
- Blade components, push arms and pivot points.
- Other Heavy Equipment (We can evaluate additional equipment based on the location, bore and repair requirements.)
Bore Welding & Restoration
When a bore has significant wear, machining alone may not leave enough material to restore it to the required dimension. In these cases, the worn area can be rebuilt using weld buildup before being precision machined back to size. This process allows a damaged component to be restored rather than replacing an entire assembly. If your equipment has worn or oversized bores, contact Blake’s Repair Service to schedule on‑site bore welding and line boring service.
Common Line Boring Repairs
When a bore has significant wear then the worn area can be rebuilt using weld buildup before being precision machined back to size. This process allows a damaged component to be restored rather than replacing an entire assembly.
