Liner Gaskets

I have three sets of gaskets and none of them are flat. They are off by at least a couple of thousands all around. I may try today to work down the copper ones. I may even go get some shim stock and make my own. Off the top of my head I can't think of who it is but someone will make a set to your required thickness. If you do a searce for liner gaskets I'm sure you will find them. You can do a search by looking at the right top side of this page. And welcome to the forum Harry. And I'll ask before anybody else where are the pictures?
As long as the figure eights are made of copper,you are good to go.A lot of kits come with aluminum ,and they dont last as long as you might want them to.In fact they should be refreshed regularly at ten year intervals!!!(due to galvanic corrosion)......

When I rebuilt my engine I knew that my liners were shy of the required protrusion, and I had wondered why.
I "mic'd" the old steel figure 8 gaskets and found them to be materially thinner than the new copper ones I had ordered from Moss.
The other thing that troubled me was the corrosion and rust on my old steel ones. In fact, they were all but destroyed.
Based on those factors, I'd lean toward using the copper ones in any new application.
There are others on this board with more experience rebuilding engines who may have other opinions, and I believe someone said that a "coated steel" variety of the figure eights is also available. I'd still lean in favor of copper figure 8's based on my experience.

I assume this is for your 4A?
I'd just add: It's wise to use the factory manual for guidance. Clean the seats thoroughly if the block hasn't already been cleaned. No specs of dirt can remain.
Get several small brushes ready to use. Those little six inch ones from ACE. Use Wellseal exactly as recommended.
Have a rubber hammer and a small block of wood ready to gently tap the liners into place.
Using the cylinder head bolts, large washers and old gudgeon pins or something similer, secure the liners in place so they don't move as you install the pistons and work with other engine components in the process.

My cylinder and liner kit (Mahle) came with "coated steel" Fo8 gaskets. I also got a set of "coated steel" Fo8s in the engine gasket set I bought. The coating appeared to be some sort of plastic. Both measured the same thickness, and provided the proper protrusion of the liners...on the low side, but steel doesn't compress like copper does. I did thoroughly coat in Wellseal as recommended.

Harry-
Sorry for the delayed response - club won't have a booth at Autorama, but you might bump into a few club members that are heading that way.
Here is the club website: Texas Triumph Register A good way to meet some members is one of the Saturday breakfasts.
I've sent you a private message with my contact info as well as for one of the club guys who rebuilds these engines.

Welcome to the party Harry.
Like Randy says, you can also join the club. It's amazing how many TRnuts there are in the Houston area alone. -but some of them can be wise guys.
"Any subtle tricks in putting the liners in?"
I'd begin by removing everything under the hood, then remove everything in the block. I've got that far, but I'm still in the 'taking apart' stage of the frame-off that I'm not actively working on. If I'm able to remember half the stuff I read on this forum, I'll be twice as far ahead!
I'd like to see you post some pics of your car.
