One call, start to finish
You talk to someone who has spent thirty years in this trade, not a dispatcher. Every job runs the same six steps, and you get the paperwork at the end.
- STEP 01
Call the line
Day, night, or weekend. Describe the failure and the machine, and we scope the job on the phone.
- STEP 02
Placed with the right shop
Matched to the facility that has actually rebuilt your make and model before — not whoever is closest.
- STEP 03
Teardown and inspection
Documented findings and photos. You approve the quote before any work begins.
- STEP 04
OEM-equivalent rebuild
Precision grinding, bearing packs, rewinds, and machining to original print specification.
- STEP 05
Test and balance
Dynamic balancing, closed-loop run-off, surge and hi-pot — proven before it ships back.
- STEP 06
Return and report
Delivered on schedule with a full inspection and test report for your maintenance file.
Why plants call DDP
- OEM-equivalent rebuilds
- Rebuilt to original print specification, not "good enough to run."
- Fast turnaround, 24-7 emergency
- Emergency service around the clock, because a down line does not wait for business hours.
- Detailed inspection reports
- Findings, photos, and test data on every job — evidence for your maintenance records.
- Cost savings vs. replacement
- A rebuilt spindle or screw is a fraction of a new unit, with none of the lead-time gamble.
- Asset inspection programs
- Programs that catch early signs of failure, so you schedule the repair instead of the breakdown scheduling it for you.
