I have not yet changed chain tensioners ....so I don't know too much about the job...just my 2cents

I would think the value of Heiko's tool(s) are:

1. They would allow you to avoid having to fill new chain tensioner's with oil and get them "pumped up" (that's for all of you in CA!).....exactly right....guess you have to compress, dunk them, release, and drown them. Then stick them in quickly for the setup. With the tool you don't have to worry about whether you pumped them fully for an exact setup. I would imagine oil pressure after first use would fill them to the proper extent.

2. We are changing tensioners because they are lazy dirty and may be jammed up so it maybe unwise to rely on old tensioners for the set-up as they may not be extended fully. You may end up having to clean them and then pump them up as you would new ones to ensure proper setting
