Product Description 5422690 is an aftermarket hydraulic cylinder seal kit for the excavator-side dipper arm cylinder on MST backhoe loaders.

Product Description 5422190 is an aftermarket bucket lift cylinder seal kit reference for MST M542 and M544 backhoe loaders. Parts catalogs identify it as a bucket-lift hydraulic cylinder repair kit. It differs from 5422090, referenced for the front boom lift cylinder, so the two kits should not be interchanged. Because...

As these sources do not establish one standardized English...

Product Description 5422090 is an aftermarket front boom lift cylinder seal kit reference for MST backhoe loaders. Catalogues identify it for the loader boom lift hydraulic cylinder on MST M542/M544 families, rather than the rear excavator boom, bucket cylinder, or steering system. This matters because front-loader and rear-backhoe cylinders can...
