Aftermarket replacement parts for Case tractors, excavators, skid steer loaders, backhoes, wheel loaders, and compact track loaders, including the Alpha Series SR / SV / TR / TV machines.
Parts Online carries aftermarket replacement parts for Case construction equipment, with the deepest coverage on the Alpha Series skid steer loaders and compact track loaders. Cab glass, door hardware, quick-attach pin kits, and sensors are the highest-volume service items because the Alpha Series shared a common chassis platform across the entire SR / SV / TR / TV lineup, which means body and operator-station parts cross broadly between models of similar size class.
The Alpha Series radial-lift skid steers (SR175, SR200, SR220, SR250) and vertical-lift skid steers (SV185, SV250, SV300) share the chassis, drivetrain, hydraulic main pump, and operator cab with the Alpha Series compact track loaders (TR270, TR320, TV380), which means most cab, door, hood, and quick-attach service parts cross between the wheeled and tracked machines. Wear items still cross from Alpha to B Series, but cab electronics and controls do not.
Aftermarket parts are manufactured by third-party suppliers to match the form, fit, and function of the original Case part. They replace the same OEM part number and are designed to the same dimensions and material specifications. The price difference is meaningful: aftermarket replacements typically cost significantly less than ordering the same part through a Case dealer, and for routine wear items (cab glass, door hardware, quick-attach pins, sensors) the aftermarket replacements perform identically to the OEM original. Parts Online matches every product to its OEM part number so you can cross reference what you need. If your Case dealer quoted you a part number, search that number on our site to find the aftermarket equivalent.
We do not sell parts for proprietary electronic control systems or software-dependent components. Our catalog focuses on mechanical, wear, and maintenance parts where aftermarket alternatives are well established. If you are unsure which part fits your machine, contact our team with your machine model and serial number and we will help verify compatibility before you order.
