Sparetrac Private Limited is an ISO 9001:2015 certified supplier and exporter of precision-engineered spare parts for agricultural tractors, heavy equipment and diesel engines. Quality is not a final step for us. It starts with how we select our sources and runs through inspection, packing and dispatch, backed by a robust Quality Management System (QMS).
Every part is inspected and validated for performance, durability and compatibility, so it delivers results comparable to OEM standards. Our experienced quality engineers, with expertise in dimensional inspection and component testing, check every batch against specification, work closely with our supply partners, take corrective action and keep improving reliability.
Quality management system
Six QMS principles every part goes through.
Select a stage to see what happens at each step.
Quality check instruments
What we check before a part is approved.
Every part is checked with calibrated instruments and recorded in batch inspection reports for full traceability. Swipe or use the arrows to see the instruments in our QC lab.
Height gauge
Heights, depths and step positions checked from a surface plate with a height gauge and dial indicator.
- Surface-plate reference
- Calibrated gauges
Micrometer
Precision diameters such as piston skirts, pins and journals measured with calibrated micrometers.
- 0.001 mm resolution
- Calibrated gauges
Bore gauge
Inside diameters of cylinder liners, bushes and housings checked for size, ovality and taper.
- Ovality & taper
- Liners & bushes
Dial gauge
Run-out, bend and flatness on crankshafts, camshafts and axle shafts measured with a dial test indicator.
- Run-out check
- Crankshaft journals
Ring & plug gauges
Threads and bores checked GO / NOT GO with calibrated ring and plug gauges, so every part fits first time.
- GO / NOT GO
- Thread fit check
Spline gauge
Splined hubs, PTO shafts and gearbox shafts checked with spline plug and ring gauges for a correct fit.
- Spline GO / NOT GO
- PTO & gearbox shafts
Gear tooth vernier
Tooth thickness on transmission gears, crown wheels and pinions measured at the pitch line.
- Tooth thickness
- Gears & pinions
Quality assurance
How we keep standards high.
