1594269 Cab Door Gas Spring Fits Caterpillar Industrial 420E 450E

What This Part Is

This is a gas-charged lift and hold strut for the operator cab door on Caterpillar backhoe loaders. It replaces Caterpillar OEM number 1594269 (written in Caterpillar's dashed format as 159-4269). The strut does two jobs at once: it holds the door open so it does not swing or drop on the operator, and it cushions the door as it closes so it does not slam. You receive one strut per order.

Fitment

This strut fits the cab DOOR on Caterpillar E and F series backhoe loaders: 416E, 420E, 428E, 428F, and 450E. On these machines the cab door uses this single strut. The rear cab window on the same models uses a different gas spring (Caterpillar 1641328), so if your window strut is the one that is weak, order that number instead. Caterpillar backhoe loaders use several similar-looking struts around the cab, so match your old part by its Caterpillar number before ordering.

Specifications

The strut is a sealed, nitrogen-charged, maintenance-free unit with low-friction internal valving for smooth, consistent operation across its stroke. Both ends use ball-socket fittings that snap onto the factory ball studs and rotate for easy alignment, which lets the strut install in the original mounting positions with no modification. Exact published length and force figures are not listed in Caterpillar's public catalog for this reference, so match the physical strut and its ball-socket ends to your original.

What Is Included

One cab door gas strut. Mounting ball studs and hardware are reused from your machine and are not included.

Cross Reference and Ordering Guidance

Replaces Caterpillar 1594269 / 159-4269 (DOOR GP-CAB). The companion cab window spring for these same models is Caterpillar 1641328 and is a separate part. Confirm you are replacing the cab door strut, not the window strut or an engine-hood strut, and confirm your machine is a 416E, 420E, 428E, 428F, or 450E before ordering.
