VEHICLES WITH ENGINES 104, 111, 112, 113, 119, 120, 601-606 UNIVERSAL TOOL FOR REMOVING AND INSTALLING VALVE SPRINGS
This comprehensive tool kit is available for removing and installing valve springs. With this tool kit, the anchoring of the lever arm (Circle, Figure 1) is achieved using the existing threaded holes in the cylinder head. On engines with hydraulic lifters, the valve keepers can be removed and installed by pressing down on the valve spring with the mounting element. The mounting element will also work with angled valves, as in V8 and V12 engines, and in the confined space of the engine compartment. This permits the valve springs to be easily removed and installed in order to change valve stem seals, for example, with the engine still installed in the vehicle. The tool kit comes with a German instruction sheet. Included in this Service Information is an English version of the Operating Instructions.
Please ensure that a copy of the English Operating Instructions is placed inside the tool kit upon purchase to facilitate proper use of this special tool.
Special Tools
Engines without hydraulic lifters, or engines where the camshaft must be removed to mount the tool (engines: 604-606).
The valve keepers are removed and installed with a magnetic pen (part no. 210 589 00 40 00) or a magnetic finger (part no. 116 589 06 63 00), after pressing down on the valve spring with the spring compressor (7, Figure 2).
The adjustable anchor (18, Figure 2) is attached to the appropriate foot (12-15, Figure 2) which is screwed into the existing threaded holes in the cylinder head (Figure 3). A selection of anchor feet (12 - 15, Figure 2) is available for the various engines.
Engines 111, 119, 601, 602 with hydraulic lifters (except diesel engines 604 - 606).
The valve keepers are removed and installed using a mounting element (8, Figure 4), which is guided into the hydraulic lifter bore through a guide sleeve (10, Figure 4). Use the same anchors and feet as previously mentioned (12 - 15, Figure 2) to anchor the lever arm in the existing threaded holes located in the cylinder head itself (Figure 3).
Valve keeper removal
Insert guide sleeve (10, Figure 4) into the hydraulic lifter bore. Insert mounting element. Mount lever arm and turn adjustment screw (8a, Figure 4) until the inner alignment shaft noticeably engages between the valve keepers. Press down lever arm (valve keepers are released). Release tension and remove valve keepers from mounting element.
Valve keeper installation
Insert valve keepers into mounting element, observing proper positioning. Press down mounting element and lift inner alignment shaft, via the adjustment screw (8a, Figure 4). Release tension (valve keepers are installed).
