Subtropical Gulf Coast climate.
For heavy equipment machining, the service area covers roughly 200 miles from central Sinton. Urgent requests can be submitted any time; response time depends on the local provider.
Common reasons to call
- Worn pin and bore on a track loader, dozer, or excavator
- Hydraulic cylinder rod, gland, or barrel rebuild
- Line boring a worn pivot or bucket attachment
- Crankshaft, journal, or rod work on a large diesel
- Resurface a cracked or warped exhaust manifold or head
- Bushing replacement and machine fit on a port crane or yard truck
- Custom shaft, key, or coupling for a downed machine
- Reverse-engineer a discontinued part
- Heat shrink or press fit on a large gear or bearing
- Field machining in place when teardown is not practical
Typical work
- Portable line boring of pins and bushings in place
- Cylinder honing, rod polishing, and chrome work for hydraulics
- Large lathe turning of shafts up to multiple feet long
- Mill work for housings, brackets, and adapter plates
- Crankshaft grinding and connecting rod resize
- Press operations for bearings, bushings, and gears
- Welding plus machining to restore worn surfaces to spec

Common questions
What is line boring and when do I need it?
Line boring is the in-place machining of a worn pivot bore back to a true round and concentric size, then installing a new bushing. It is used when the bore is too worn or oval for a standard bushing to fit cleanly.
Can you come to my equipment, or does it have to come to the shop?
Both. Portable line boring and field machining bring the tooling to the job. Larger turning, milling, and crankshaft work happens at the shop where the bigger machines live.
What size shafts can you turn?
Shop capacity varies. Common heavy machine shops handle shafts up to multiple feet long with significant swing. Confirm length, diameter, and weight when scheduling.
Do you rebuild hydraulic cylinders?
Yes. Service includes rod polish or replacement, gland and seal kit, barrel inspection, and pressure test. Chrome work is subcontracted to a plating partner when required.
Can you reverse-engineer a discontinued part?
Yes. With the original part in hand, calibrated measurement and CMM verification recreate the dimensions. A drawing package can be delivered along with the new part.
What customers do you serve?
Construction fleets, port and terminal operators, oilfield, marine, agricultural, municipal, and ready-mix concrete are common customers in the Coastal Bend market.
Do you weld repair worn surfaces?
Yes, where the OEM allows it. Worn surfaces can be built up with the correct filler and procedure, then machined back to spec. Some assemblies require qualified procedures and certified welders.
Can you certify the dimensions?
Yes. CMM inspection and a written dimensional report are available for parts that require it. ISO 9001 customers and aerospace-grade customers usually require it.
Coastal Bend seasons
Spring (March - May)
Construction and dredging season ramp brings cylinder rebuilds and line boring work on idle equipment.
Summer (June - August)
Peak heat and operating hours expose bushing wear and crank fatigue. Field machining call volume rises.
Fall (September - November)
Budget cycles drive planned refurbishment on yard equipment before year end.
Winter (December - February)
Slower field season is the window for crankshaft, gearbox, and one-off custom work.
