Parts Compatibility for John Deere Excavators

John Deere excavators span two main platforms. The D-Series includes 120D, 160D, 200D, 240D, 270D, 300D, and 350D machines produced through the mid-2010s. The G-Series follows with 130G, 160G, 180G, 200G, 210G, 250G, 290G, 350G, and 380G covering Tier 4 Final emissions and updated cab ergonomics. Compact excavators like 27D, 50D, 26G, 30G, 35G, and 50G share a different parts catalog from full-size machines.

Cab glass shows significant variation across the lineup. Front Lower Glass 4664383 fits the D-Series excavator cab, while Front Center Glass T344818 covers late E-Series and G-Series machines. Cab Door Glass 4684428 is specific to the 85D and 85G-Series compact excavators.

Excavator mirrors like 4675257 Model G Excavator Mirror and 4420724 cover most of the lineup with appropriate mounting arms for excavator cab profiles. Always verify fitment by serial number, especially across the D to G generation transition.

Common Replacement Parts for John Deere Excavators

The most frequently ordered John Deere excavator parts include cab door glass, windshield panels, mirrors, engine air filters, hydraulic filters, and cab door hardware. Front Lower Glass 4664383 and Front Center Glass T344818 are top-selling glass items. Excavator Mirror 4675257 is the common G-Series replacement.

Compact excavator parts for the 27D, 50D, and G-Series smaller machines typically have their own specific part numbers that do not cross to full-size excavators. Kit-based replacements like cab glass kits with pre-attached gaskets simplify installation for operators working without a full service kit on hand.

Filter cross-references for excavators include the common Spin-On Hydraulic Filter AT38431 which fits many full-size machines, plus specific part numbers for the Tier 4 Final G-Series platform.
