Gunson Click Adjust tappet tool

[Guest]

Just skip dived one of these tools. Seems simple enough to use (once you have worked out number of clicks for a particular engine.) Seem about 50/50 on car forums as to whether they are worthwhile. I plan to try it on my Vetus and wondered if anybody has ever tried one?

Many thanks.

I had one in the 70's. It was fiddly to use so I gave it away. It was quicker and easier to use a feeler guage, ring spanner and screwdriver.

I used one in the sixties on a variety of BMC A & B series engines. It was very effective, mainly because the engines were pretty worn, and it got around the problem of the rocker pads being slightly indented. If I recall correctly, there is a way of working out the number of clicks if you know the thread dimensions of the adjustment screw, and the clearance you are trying to achieve.

I spent years using feeler gauges before eventually buying a click tool but by then OHC engines were becoming the norm and it became redundant, still got it somewhere.

I used something similar for the same reasons. We apprentices had discovered that you get more bangs on the back seat of a banger than the back seat of a BSA. Even if it was a Road Rocket. They compensate for wear on the pads so bad that setting would be imposible with feeler guages. I wish I stll had that £25 Moggie Thou.

Thanks everyone for advice/comments, and Flyboy for the instruction link. Will give it a whirl next time I check the tappets. Always seems a three handed job with feeler gauges, so rather hoping this will make it a little easier.
