Product Description 5422890 is an aftermarket piston seal kit for the hydraulic lock of the rear carriage on MST backhoe loaders. It is used to reseal the piston within the locking mechanism that secures the rear excavator carriage assembly; it is not a standard boom, dipper, bucket or hydraulic control-valve...
Product Description 5442390 is an aftermarket hydraulic seal kit reference for the boom swing, or arm-rotation, cylinder on MST backhoe loaders. It supports the cylinder that pivots the excavator boom laterally, rather than the lift, dipper, or bucket cylinder. Published catalogs list MST M542, M544, M542 Plus, M544 Plus, M642,...
Product Description 5422790 is an aftermarket hydraulic seal kit reference for the excavator-side bucket cylinder on MST M542 and M544 backhoe loaders. It is used when a confirmed bucket cylinder is removed for resealing after leakage, seal wear, or loss of hydraulic holding performance. Parts catalogs associate this number with...
Product Description 5422690 is an aftermarket hydraulic cylinder seal kit for the excavator-side dipper arm cylinder on MST backhoe loaders. It is referenced for MST M542, M544, M542 Plus, and M544 Plus machines, with KK470 also appearing as a market reference. This kit is intended for cylinder resealing during repair...
Product Description 5422590 is an aftermarket hydraulic cylinder seal kit reference for MST backhoe loaders. Trade catalogs identify it as a “kazayak” cylinder repair kit, while published purchasing records describe it broadly as a boom-cylinder repair kit for an MST 544. As these sources do not establish one standardized English...
Product Description 5422490 is an aftermarket hydraulic cylinder seal kit reference for MST M542 and M544 backhoe loaders. Published parts catalogs list this number for both the telescopic dipper cylinder and the stabilizer cylinder, so the installed cylinder group must be confirmed before ordering. It is not a universal boom...
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...
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...
Product Description 87038297 is an aftermarket lift cylinder seal kit reference for Case and New Holland farm loaders. Parts diagrams identify it at the lift cylinder, including versions marked “head with flats” or 35.701.010 on some loaders. This matters because one loader family may have earlier and later cylinder arrangements...
Product Description 335-1414 is an aftermarket control valve seal kit reference for compatible Caterpillar backhoe loaders. A 424B parts manual shows it in a control-valve/control-bank assembly, not a cylinder group. It supports resealing the applicable valve location during control-valve service. The public listing does not identify a universal valve position...
Product Description 487-6170 is an aftermarket hydraulic piston pump seal kit reference for compatible Caterpillar wheel loaders and D7 track-type tractors. It services the hydraulic pump assembly that produces oil flow for the hydraulic circuit; it is not a piston motor, cylinder, or control-valve kit. Official fitment lists models, but...
Product Description 310-5742 is an aftermarket hydraulic relief-valve seal kit reference for compatible Caterpillar wheel loaders. Unlike a solenoid valve kit, it services a pressure-relief valve in the hydraulic circuit rather than an electrically actuated valve. Do not order by loader model alone: hydraulic configurations can vary by serial number...
