Triumph TR6 restoration: disassembling the engine

Well, everything looked as expected for an engine that probably hasn’t been freshened up since it was manufactured nearly fifty years ago. The cylinders looked fine to me, as did the pistons, but my machine shop of choice HDS/Carquest in San Marcos thought otherwise. Casey, the owner, knows what he’s doing. I absolutely trust him. Before getting the block and head over to him for the serious business, I decided to clean up the combustion chambers, ports, and connecting rods myself, as shown in subsequent posts.

Triumph TR6 restoration: Engine stand installation

The other engines I’ve rebuilt were always mounted onto the stand at the rear of the block. After reading what other TR6 owners had done, I chose the side mount. This worked out very well, and the 12″x6″ quarter inch thick plate was plenty strong… no flexing or movement at all.

Triumph TR6 restoration: Removing the engine

The engine removal was straightforward. I left transmission and cylinder head attached, but removed manifolds and alternator, disconnected driveshaft, wires, and hoses. The head was stuck on the block so we used the hoist to separate it from the block, making sure it was pulled up evenly. Because the hoist was fully extended to the 1/4 ton hole, I added a reinforcing square tube all the way to the hook, which required drilling a hole for the 1/4 ton pin.

1973 Triumph TR6 rescue and restoration

Here are a few pictures depicting the state of the Triumph after sitting outside under a fabric car cover for twenty years… thank goodness it resided in Southern California. But it was truly a rodent hotel.

Clearly we are looking at new floor pans in the passenger area, as well as the trunk. And pretty much everything else!

One word of advice for you when cleaning out an old car that has been host to rodents… MASK! The trunk, for example was at least four or five inches deep in droppings and twigs and nut shells and dirt. Gross.

I was somewhat careful about wearing a mask as we filled a garbage can with rodent droppings and shells and whatever the heck all that other stuff was, but not as careful as I should have been. My lungs have literally never been the same since that original cleanup. This is serious advice, heed it, please! Best practice would have been a good painter’s mask with dual filters, reasonably priced at Harbor Freight. I did utilize one, but there were occasions when I just wore a paper or cloth mask… that is not sufficient.

British invasion, The ’73 Triumph

After declining to rebuild my neighbor Wendy’s Triumph TR6 for a few years because I was too busy building these old trucks, she finally approached me with an offer I couldn’t refuse. “Give me $250 and send another $250 to my favorite charity, and it’s yours.” Thus began a two year rebuild… not at the Barn but in my garage at home.

My plan for this narrative is just to post pictures of the process, with captions. I’m sure that there will be posts dedicated to specific problems and solutions, but this build story will be heavy on photos.

Here is the current state of the TR6 as of Fall 2021…
