My portable diesel generator, which powers a small construction site, has stopped cranking completely and the paired water pump now sits idle beside it. I need a seasoned mechanic who can move beyond basic maintenance and carry out a full repair and service cycle: • Run engine-side diagnostics to pinpoint the “won’t start” fault—fuel, air, electrical, and compression checks. • Strip, clean, and replace any worn or damaged parts (filters, injectors, hoses, belts, seals, starter components—whatever the inspection shows). • Flush and service the connected water pump so both units are ready to work together again. • Reassemble, re-tune, and perform load and performance testing to confirm reliable output under typical construction-site demand. You’ll bring your own diagnostic kit (OBD tools, multimeter, compression tester, leak-down gauge) and any specialty hand tools. I’ll cover parts once we agree on a list generated after inspection. A concise service report that details findings, replaced items, and final test results will be the final deliverable.

Hello, Having worked extensively as a senior mechanical engineer, I have developed an unrivaled expertise in various aspects of mechanical systems and maintenance. I specialize in precise diagnostics and repair, traits that prove crucial when dealing with the complexity of diesel generators and water pumps. Throughout my career, I have consistently demonstrated the ability to identify and rectify faults effectively, ensuring optimal performance from the repaired units. My proficiencies in using OBD tools, multimeters, compression testers and leak-down gauges mean that I am fully equipped to run comprehensive diagnostics on your generator. This will involve fuel, air, electrical, and compression checks to guarantee that no stone is left unturned in pinpointing the "won't start" fault. Additionally, my familiarity with mechanical design, 3D modeling and CAD enables me to strip down and rebuild components efficiently - an imperative process in repairing damaged parts as revealed by the inspection. In line with your needs for a reliable generator on your construction site, load carrying capability and output testing are not areas I will overlook or rush through. For me, operation under typical environmental conditions should be non-negotiable. Once the service is completed, I'll provide you with a detailed report on my findings and all replacement items. It’s clear from your description that you appreciate professionalism alongside e Thanks!

You need a mechanic to fix your portable diesel generator that won't crank and its water pump. I will travel to your site with my own diagnostic kit to perform the full repair and service cycle. I will start with engine-side diagnostics, checking fuel, air, electrical systems, and compression to find why it won’t start, then strip, clean, and replace any worn parts like filters, injectors, hoses, belts, and starter components as the inspection shows. The water pump will also be flushed and serviced so both units work together again. After reassembly, I will retune the generator and perform load testing to confirm reliable output for construction-site demand. I would assume the generator and pump use standard diesel engine and centrifugal pump components respectively until you tell me otherwise. My Freelancer review history shows 10 reviews at 5.0, with everything delivered on time and on the agreed price so far. Is the generator model readily available, or will it require disassembly to identify it? A short call on Freelancer to settle the scope would cover confirming the site location and the expected turnaround time.
