Product Overview
A telehandler often works under falling dust, rain, and concrete debris. If the hydraulic cap is missing, cracked, or no longer seals, contamination can enter the reservoir every time the boom cycles and the oil temperature changes.
The cap closes the hydraulic filler neck and provides keyed access. It is not a pressure cap or fuel cap, and the non-vented arrangement must match the machine design.
Confirm 142-8937, reservoir label, thread, seal diameter, lock style, model suffix, and serial number. Similar telehandlers can use different filler caps.
