11.3.4 Mono-couplings
The mono-couplings must be replaced if:
- there is external damage,
- the locking does not function,
- hydraulic fluid continues to leak in the coupled/uncoupled state.
WARNING/CAUTION!
Never repair couplings: they must be replaced by genuine HURST parts!
Procedure for coupling to valve block:
1. First empty the hydraulic tank as described in the chapter "Replacing the hydraulic fluid".
2. Remove screwed fittings on the coupling.
3. Remove couplings and underlying seals
4. Position the new coupling, together with the seals, onto the valve block.
5. Re-attach the couplings with the bolts and tighten to a torque of M
A
= 40 Nm.
6. The hydraulic fluid tank must be refilled and the power unit vented.
3. Loosen the union nuts on the hose lines and remove the coupling.
Procedure for coupling to hose pairs:
1. First empty the hydraulic tank as described in the chapter "Replacing the hydraulic fluid".
2. Pull the kink-protection back from the couplings.
