| Brand | Type / Series / Model |
|---|---|
| JCB | Backhoe Loaders: 3CX, 4CX (P21 cab models only, 2001 and newer) |
The list above is for reference. It is crucial to verify your cab type (P21) and strut dimensions.
When replacing struts, we recommend replacing both (left and right) at the same time for even operation. Also, check the condition of the window hinges and latches.
A failed gas strut poses a serious hazard. Loss of holding force can cause the heavy rear window to slam shut suddenly, risking severe head injury or crushing an operator's hands. Do not attempt to repair or puncture gas struts.
The 331/28215 gas strut is a sealed cylinder containing compressed nitrogen gas and a small amount of oil. Its job is to assist in lifting the rear window and, most importantly, to hold it securely in the open position. The 850N force is precisely calculated to balance the weight of the glass.

850 Newtonów (N) to siła, z jaką siłownik wypycha tłoczysko. Odpowiada to w przybliżeniu udźwigowi ok. 85 kg. Jest to siła niezbędna do zrównoważenia ciężaru tylnej szyby.
Nie. Ten model (331/28215) jest przeznaczony do maszyn wyprodukowanych po 2001 roku (kabina P21). Maszyna z 1995 roku ma starszy typ kabiny i wymaga innego siłownika o innych wymiarach.
