Minor clarification. There are two tools... the lock tool, which is $20-$30 or so, but some people claim to have had trouble purchasing it in the USA. Here is a photo: http://www.w124performance.com/images/tools/IP__lock_tool.jpg
The other tool is the proper tool that has two lights. This tool costs $250 or so, but is what the factory service manual specifies for setting pump timing. Here's a photo: http://www.w124performance.com/images/tools/IP__RIV_tool.jpg The lock tool is NOT intended to be used to set/adjust timing, but it can be used to accomplish that - it just takes a little more work, and more care - if you turn the engine with the lock engaged you can bend/break the tab inside the IP and not be able to set timing correctly at all (read: buy a used IP from a salvage yard.) First step is to check the camshaft timing relative to the crankshaft since you rolled in a new chain, if that's at zero like it should be, second step is to set pump timing. I'm told some people can come pretty close with NO tools by using a mirror to look for the little tab through the hole in the IP but I've never attempted this. :-) HTH, Dave M.
