BT 129881 (LIFT CYLINDER KIT)

Frequently Asked Questions

Q: What BT manual pallet jack models does the BT 129881 (LIFT CYLINDER KIT) fit?
A: The BT 129881 lift cylinder kit is a direct OEM replacement for BT L2000, BT L2000-U, BT L2300, BT L2300-U, BT LHM230, and Rolatruc L23 models. Verify your exact model before ordering to confirm compatibility.

Q: What seal materials are used in the BT 129881 lift cylinder kit?
A: This lift cylinder kit contains nitrile (NBR) seals paired with PTFE backup rings designed for piston and gland service. The nitrile compound resists standard hydraulic oils and maintains performance across normal operating temperature ranges.

Q: What is the pressure capacity of the BT 129881 lift cylinder kit?
A: The BT 129881 supports hydraulic working pressures up to 3500 PSI, which matches the original BT manual pallet jack specifications. Operating above this pressure may damage seals and cause system failure.

Q: Can the BT 129881 be used as a direct replacement without modification?
A: Yes, the BT 129881 is engineered as a direct OEM replacement and requires no modification for BT L2000 and L2300 series models. It is designed to fit the existing lift cylinder bore and rod dimensions.

Q: What symptoms indicate that the BT 129881 seals need replacement?
A: Replace the seals when you observe hydraulic leakage around the cylinder rod, slow lift response, or inability to hold load pressure. These are signs that the nitrile and PTFE components have degraded or worn.
