Beck TD, Part 46: The Grand Re-wiring!

O Lord, the MG faithful are going to throw me out over this one! Oh, wait... they already did, because Beck TD is Volvo-powered. At the end of Part 45, which was a detailed, involved exploration of  converting from generator to alternator power, I posted this photo:

Beck TD, Part 45: Alternator Conversions

I'd like to introduce you to Jake Roulstone, my co-author for this post! Jake is a deeply knowledgeable guy I met via the Volvo Engined MG group. He also has a Volvo-powered TD, and his day job as a maintenance supervisor for an asphalt paving company has given him a deep respect and concern for reliability. Just imagine a broken truck, with the full load of asphalt hardening in the truck, and you'll get the idea...

Jake and I agreed to jointly write a procedure to convert from the ancient generator technology to a modern alternator, specific to the world of MG cars with Volvo engines. This is one of those collaborations that has only become possible with the Internet, because Jake lives in sight of the Pacific Ocean, and I live a couple of hours from the Atlantic! There's a lot to consider, and much of it is pretty technical. So.... my first caution is, don't start until you understand every step and implication of the process! Here's a photo collage of both conversions, Jake's to the left, and mine to the right:


While they look similar, they are actually rather different in ways that will be explored below. Let's start with all the decisions you need to make:

Beck TD, Part 44: Trimming the Ram's Horns

The Ram's Horn is an engine part in early Volvos - it vents oil fumes to the atmosphere, in those pre-emissions-controls times. I don't feel guilty for running one - it makes Beck TD look more "vintage," and I've only driven the car about 200 miles in almost two years. As the accountants say, that mileage is "not material" in terms of cleaning up the air. I think the official name of the part is "Road Tube" but Ram's Horn is a common name among enthusiasts due to its shape.

Beck TD, Part 43: Joe's Amazing Tool

Everyone who has anything to do with old Volvos knows who Joe Lazenby is. He owns Susquehanna Spares, and he has a big collection of vintage Volvo parts and complete cars. It was from Joe that I recently bought a replacement B18 engine and M40 transmission for Beck TD. In the course of three recent visits, Joe asked me to create a special tool for him. It's a special sleeve that aligns the rear main seal housing perfectly concentric to the rear of the crankshaft. He sent this picture of one owned by a friend:


Being kind of dumb and optimistic about my abilities, I said, "Sure, I can make that." Of course, I didn't consider that my hobby-grade machine tools were not even capable of doing the job, nor were my skills up to snuff. Fortunately, I know Phil Oles...
