ABSTRACT:
An assembling device receiving a valve-actuating subassembly intended for installation about a valve stem in an internal-combustion engine. The subassembly includes a valve spring having opposite first and second ends and a valve spring retainer abutting the valve spring at the first end thereof. The assembling device includes a holder abutting the valve spring retainer; and an axial extension surrounding the holder and being axially displaceable relative thereto. The axial extension includes a stop at a first end of the axial extension for preventing the holder from separating from the axial extension and a hold-back arrangement at a second end of the axial extension for releasably engaging the valve spring at the second end thereof, whereby the stop and the hold-back arrangement together releasably secure the subassembly to the assembling device.
