Related Parts and Hardware

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.

⚠️ Safety Warning

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.

Part Role in the Machine and Failure Diagnostics

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.

  • › Rear window falls shut or will not stay open.
  • › Requires significant effort to open (lift) the rear window.
  • › Window lowers slowly, especially in cold weather (loss of gas).
  • › Visible oil leaks from the strut's piston rod seal.
  • › Damaged or broken end fittings (sockets).

🔧 Expert Guide: Key Installation Tips

  1. Replace in Pairs: Always replace gas struts in pairs (left and right). Replacing only one will cause uneven lifting and overload the new strut.
  2. Support the Window: Before removing the old struts, ensure the rear window is securely propped open or held by a second person.
  3. Correct Orientation: Install gas struts with the piston rod (thin part) pointing down and the cylinder (thick part) pointing up. This ensures the seals remain lubricated.
  4. Check Mounts: Ensure the ball studs on the frame and window are not damaged or worn.

Najczęściej Zadawane Pytania (FAQ)

Co oznacza siła 850N?

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.

Mam 3CX z 1995 roku. Czy ten siłownik będzie pasował?

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.
