A fleet operator reported operational issues with their construction equipment equipped with VOLVO diesel injector 1742535. The equipment exhibited engine misfires, power surges, excessive vibration. After inspection, the problem was traced to the DAF series injectors, which have cross-reference numbers 1661060 and 1725282 for different VOLVO engine models.
· Primary issue: internal wear and tear affecting fuel delivery and atomization
· Secondary issue: clogged fuel filters
· Secondary issue: low cylinder compression
· install new injectors and rebuild cylinder heads
· Clean fuel tank and fuel lines
