Removing the tappets and guides

There are a few tools that make pulling Listeroids down fun, one of these tools is Golightly Tappet Jack from utterpower.com.  This tool allows you to pull the tappet out of its bore without damaging the indexing surface. This is a critical surface that can cause the tappet face and cam to meet at the wrong angle when damaged.

Always keep in mind that the tappet is sitting on the cam; don’t beat on it.  If you’re going to try and remove them by other means, avoid using a chisel point between the deck and index surface; it usually makes a mess out of things.

The key to extracting these parts is to get the paint off the tops of the tappets so the guides can be pulled over them without the tappet sticking in the guide bore. The right way to pull guides is by their tops, borrow or buy a Go-Lightly Tappet guide jack. Once you get all this paint out of the way, you can establish a decent fit between the tappet guide and the deck, and assure that it will be easier next time.

If you didn’t listen to my warning, and you have the tappet stuck in the guide due to the paint you didn’t remove,  put blocks under the jacking bolts of the Golightly tappet jack, and use the jack to force it over the paint. What ever you do, remember there’s a cam lobe down the hole, and do not hammer on the guide when the tappet is stuck. This could cause damage to the tappet face or cam lobe.

The tappet jack (sold out), you can make your own. This tool was discontinued because the jack pulls the tappet guide from an outside OD that has no tolerance in India! It appears they turn this OD to whatever the machinist feels like cranking out that day! Example of how it works  is on the CD.
