This is the heart of your tool set.  Unlike wrenches or sockets, there is no different tool for each size fastener.  This tool will take the brunt each time you use a socket.  This is no place to pinch pennies.  There are three primary considerations with a ratchet. The first, is how well it fits in the your hand.  Some ratchets use a basic steel handle with a shape designed to feel comfortable in the hand.  Others use a plastic handle so that when working in a cold shop or hot engine, the heat is not transferred to your hand.

Sockets have many things in common with wrenches.  They same ideas of fit apply, and the same ideas of 6 point and 12 point apply.  Sockets also have depth, so you need to consider sockets that are normal depth, shallow (to fit into tight working areas) or deep, to help you reach hidden places like spark plug holes.  It is customary when buying sockets to purchase 4 major sets.  Normal Metric 6 point, normal Metric 12 point, normal SAE 6 point, and normal SAE 12 point.  These sockets will be used for practically every DIY job on your truck and you should purchase qu

The wrench is probably the most basic of all tools.  There are several varieties including open end, box end, combination (having one open end and one box end), flare nut, striking wrenches, etc.  But the primary job of these wrenches is to fit onto a fastener and allow us to tighten or loosen it.  In order to do that, the tool must fit the fastener properly.  It must offer enough leverage for us to loosen or tighten, and it must fit the hand well.  If you examine common fasteners, you will find that most have 6 sides.  On the rare occasion, you may find one wi

Tin is the layman's general term for what the expert wouldcall "metal". There are many different kinds of "tin".
BRASS is a very useful sort of Tin. It is mined in Yorkshire, and is said to occur wherever there is muck. Out of Brass we make Monkeys, Knobs and Money.
NICKEL is the sort of Tin used for making American money.

The Airflow Meter (AFM) in my fuel-injected Triumph TR7 failed due to condensation and corrosion three weeks ago. This note is meant to help others avoid the problems I had in debugging the problem, and possibly even keep them from experiencing it in the first place.
The AFM is a Bosch part of L-Jetronic fuel-injection. A similar part is used in the Triumph TR8s that are fuel-injected.

Bosch L-Jetronic fuel injection was found on 1980 California-only wedges and on all wedges for 1981 and 1982 (except European/UK markets). The system is entirely Bosch (parts are readily available, both mail order and locally) on both the TR7 and TR8 with one very important exception. The TR8 has a Lucas-designed computer control unit (ECU). That's been troublesome and there have been a whole series of articles (both in the TR8 Car Club newsletter and The Vintage Triumph, VTR's magazine) written on how to fix it. Other questions/problems/useful facts about FI are listed below.
