Machining Repair & Component Rework
Restore worn or damaged parts to OEM—or better—precision.

Overview
Whether performed in-house or through our trusted Canadian partners, Pearson Manufacturing delivers high-quality machining repair and component restoration. Our hybrid fulfillment model lets us match the process to the part—so you get the right sequencing, documentation, and turnaround every time.
⚠️ Hybrid fulfillment: not all repairs are performed on-site—routing is chosen for capability, speed, and compliance under Pearson QA.
Quick Specs
| Service | Best For | Speed | Notes |
|---|---|---|---|
| Polish/Grind & Size | Light wear, minor scoring | Fast | Restore surface & diameter; verify fit/runout |
| Sleeve/Bush & Machine | Worn bores/shafts needing new bearing surfaces | Medium | Install sleeve/bush; machine to spec; adhesive/thermal fit as spec’d |
| Weld Build-Up + Machine | Deep wear, chips, cracks at edges | Medium | Qualified weld, stress-relieve as needed, re-machine to print |
| Recreate/Reverse Engineer | Obsolete or broken beyond repair | Varies | Measure sample, model, and machine a new part to OEM or improved spec |
Access Machining Repair For
- Worn or scored shafts, pins, and journals (re-size, polish, grind)
- Bent or damaged rods (straighten by review, or replace and fit)
- Out-of-tolerance bores, faces, and keyways (bore/line-bore, sleeve, re-cut)
- Cracked/chipped flanges and mounting faces (weld build-up + machine)
- Reverse engineering for obsolete or hard-to-source components
- Fit restoration for bearing seats, seal lands, and press fits
Techniques We Provide
Work may be executed by our in-house team or through qualified local suppliers, depending on complexity and lead time.
- Turning, milling & precision grinding for re-machining critical features
- Weld build-up (process by material) with stress relief and finish machining
- Sleeving/bushing of bores or shafts; thermal/adhesive fits as specified
- Line-boring and on-center restoration of multi-bore features
- Reverse engineering from samples; drawing/model creation for approval
- Surface restoration, polishing, and deburr to functional finishes
DFM & Repair Prep
- Provide target fits (e.g., H7/g6 or class of press/clearance) and thread/feature standards for verification.
- Note any heat-treat or coating history; repairs may require stress-relief or post-process finishing.
- Flag only CTQ dimensions for tight tolerances—broader bands reduce cost and lead time.
- When sleeving, specify preferred sleeve alloy and wall allowance; confirm adhesive/thermal spec.
- Share mating part information (bearing, seal, coupling) and desired surface finish on contact areas.
- For cracked areas, include photos showing extent and direction; we’ll define a repair procedure.
We’ll confirm method, sequencing, and documentation before kickoff.
Why Choose Repair Over Replacement?
- Cost-effective alternative to full replacement
- Fast turnaround minimizes equipment downtime
- Rebuilt to OEM specs—or better—where practical
- Sustainable reuse of worn or obsolete parts
- Hybrid routing expands capacity and specialty processes under one QA umbrella

Repair FAQs
What parts can you repair?
Shafts, pins, rods, bores, flanges, faces, housings, and similar metallic components. Send photos and key dimensions for a fast feasibility check.
How long does a typical repair take?
Many jobs complete in 3–5 business days depending on process (weld/heat-treat steps may extend). Expedite options are often available.
Do you inspect parts before quoting?
Yes—visual and dimensional review is performed before quote. For reverse engineering, we measure a sample and confirm CTQs before kickoff.
Is this work performed in-house?
Some work is done at our Ontario shop; specialized steps (e.g., large line-boring, certain coatings) may be routed to trusted Canadian partners under Pearson QA. Request a repair quote — include material, damage photos, CTQs, and your timeline.
Can you improve on OEM?
Often—common upgrades include harder sleeve materials, improved seal finishes, or revised fit classes. We’ll propose options during DFM.
