§1What this business is
Nozzles of diesel engines choke with carbon, so trucks, buses, tractors, cars and generator sets need this job often. The fuel pump is taken off the vehicle and run on a test bench; the nozzle is then tested and, if needed, ground and reconditioned on a machine, and the pump is refitted. The work is pure job work with no raw material except a little diesel and kerosene. The profile sets yearly capacity at 3,600 pump tests, 3,600 nozzle tests and 3,600 nozzle grindings, worth ₹7,02,000.
Capacity: Single shift, 300 days: 3,600 pump tests (₹5,04,000), 3,600 nozzle tests (₹72,000) and 3,600 nozzle grindings (₹1,26,000) a year.
§2Is it right for you?
Who it is for
A diesel mechanic trained on fuel-injection pumps, based near a transport nagar or tractor market.
Who it is not for
Someone with no hands-on diesel engine experience.
Advantages
- Diesel vehicles, tractors and generator sets need the job again and again
- Job work — almost no raw material to buy
- One test bench is the main machine
Drawbacks
- Newer common-rail engines need costlier test equipment than this bench
- Wrong calibration can damage a customer's engine
- Depends on garages nearby sending work
Skills you need
- Fuel-pump calibration on a test bench
- Nozzle testing, lapping and reconditioning
- Reading pump data charts
Why difficulty 3/5: Low cost, but it needs a specialist diesel-pump skill.
§3Market
Who buys
- Truck, bus and minibus owners
- Tractor owners
- Owners of diesel generator sets
- Garages that do not own a test bench
How it sells
- Walk-in vehicles at the workshop
- Job work sent by nearby garages
Good to know
- The profile's projected profit table does not match its own capacity figures, so no break-even is quoted here.

§7Money
How the investment is worked out: Plant and machinery ₹1,42,550 (fuel-pump test bench ₹95,000, nozzle grinding machine ₹30,000, nozzle tester ₹7,000, tools ₹10,550) + electrification, water and furniture ₹27,000 + contingencies ₹10,000 + pre-operative ₹20,700 = ₹2,00,250 fixed; plus working capital for 3 months ₹1,98,450 = ₹3,98,700. Shed is rented.
Working capital: Monthly working capital ₹66,150; the project carries 3 months, ₹1,98,450.
