Description
Yanmar 4TNV98 Engine Parts Manual covering naturally aspirated and turbocharged engines installed in specified Mustang and Gehl skid-steer and compact track loaders. This factory parts publication provides illustrated component identification, reference numbers, part numbers, descriptions and quantities for the applicable engine assemblies.
Produced for accurate engine-parts identification, the manual is suitable for parts departments, engine workshops, plant engineers and machinery owners maintaining the listed applications. Coverage distinguishes between the 4TNV98-ZNMS, 4TNV98T-ZNMS, 4TNV98-ZNTBL and 4TNV98T-ZNTBL engine versions where components differ.
The publication also identifies six engine part-number applications. Users should confirm the engine model, serial number and applicable engine part number before ordering components. Items illustrated without a part number are included for reference only.
