ENGINE OVERHAULS AND REPAIRS

We remanufacture 567, 645, and 710 engines and test them in our onsite test cell. We will build to your specification, help you develop one, or supply one that will meet your needs.

Our process:

Teardown the engine completely
Clean the crankcase, pan, and components to bare metal
Identify all important parts with our tagging system, which ensures your parts are accounted for
Undertake a thorough inspection by experienced, trained PSI technical staff
Conduct non-destructive (NDT) magnetic particle testing of critical parts
Check and measure all critical areas on engine
Make repairs as required to OEM standards
Check all threaded holes and repair
Rebuild all components (process addressed in component section)
Rebuild case and pan (process addressed in case and pan section)
Using state of the art cleaning equipment, CNC mill, certified tools, and welders, we repair the various parts to OEM standards
The engine is assembled, again to OEM standards using all new gaskets and bearings
After complete assembly, your engine is load tested to your requirements
After load test engine is inspected, re-torqued and painted
All build sheets and load test data are collected then supplied to you for your records

CASE AND PAN

When you want the highest quality, look to PSI for rebuilding or repair.

To ensure that your assembly meets OEM specifications, we:

Clean the crankcase, pan and components to bare metal
Undertake a thorough inspection by experienced, trained PSI technical staff
Conduct non-destructive (NDT) magnetic particle testing of welds and high stress areas
Check crankcase line bore with precision gauges, and retain all measurements for future reference and quick accessibility
Check all threaded holes

As needed, we then:

Repair cylinder pot cracks
Repair test cock tube cracks
Correct crankcase line bore
Repair A-frame cracks
Repair any structural damage
Repair main bearing serrations
Restore mounting pad surfaces
Repair hand hole window
Repair threaded holes
Restore cylinder pot surface
Resurface the exhaust deck
Remachine the end sheets

Following the comprehensive rebuild or repair, the reconditioned unit is shipped to you for equipping and installation. If you’d prefer, PSI will handle the refitting.

All PSI rebuilt case and pan assemblies meet OEM specifications and are backed by a PSI 1-year warranty.

To keep your equipment running, contact PSI for rebuilt engines.

CUSTOM ENGINE REPAIR

Years ago, when an engine suffered a major failure such as a broken crank, it was typical to send it for a complete overhaul. This was particularly frustrating if the engine had been overhauled relatively recently. Many components would be replaced long before the end of their useful life at considerable cost.

Peaker Services, Inc. developed its custom engine repair service to address this problem. The repair is completely custom in work scope to a particular customer’s needs and the nature of the failure. The following is a common example:

A power assembly failure results in destruction of a crank main journal and damage to a pan rail and hand hole opening. Front and rear ends of the engine are torn down, case and pan are split and the crankshaft is removed. Power assemblies that are undamaged are left in the engine and the top end remains in place. The A-frames are all magna-fluxed and it is determined that some of the serrations are cracked. These are ground, built back up with weld and serrations are re-machined on our 4-axis CNC mill (see picture). The line-bore is then measured and brought back to a re-manufactured specification. The pan rail and hand-hole openings are repaired. All this work is performed with the engine protected, but partially assembled. The engine is then reassembled and load tested at substantial savings from a complete engine overhaul.

We rotate employees over time through all areas of the shop and provide the broadest workshop possible that’s practical. As a result, our employees are extremely capable and able to work to very high standards with variable work scope. They also have the broad perspective and experience to identify issues related and unrelated to the failure so you don’t just get a partial fix.

COMPONENT ASSEMBLY

You need reliability and performance, which is what you get with PSI quality rebuilt components and assemblies.

Power Assemblies

PSI rebuilds power assemblies, either turbocharged or naturally aspirated, for locomotives, power generation, marine applications and general industrial use. As required, PSI will also build power assemblies to meet specific customer needs.

As part of our rebuilding process, we:

Undertake a thorough inspection by experienced, trained PSI technical staff
Conduct non-destructive (NDT) magnetic particle testing of cylinder heads and connecting rods
Check all dimensions, with precision bore gauges, and retain all measurements for future reference and quick accessibility
Install new valve guides
Check for valve leakage with sensitive vacuum testing
Torque each assembly to OEM standards

Note: Power assembly models 567BC, C, D, 645E, 645F, and 710G are available for unit exchange.
