Light Switch Silencer

Three views showing the shape of the “silencer”. The parts books show that in mid-1930 Ford introduced a small brass bushing, “A-3529 Steering gear lighting switch tube silencer”.  The bushing may have been used earlier (it was certainly needed) and overlooked in the parts lists.  It was formed from .006″ thick brass stock.  Listed as […]

Bulletins were sent to the Ford dealerships on a monthly basis.  Each contained eight to sixteen pages of service procedures, component changes, etc.  The original bulletins were 8-1/2″x 11″ pages.  The front page each month usually contained an image suggesting windows displays or […]

Front End Shimmy

Will a loose ball in the front wishbone at the transmission cause a shimmy?  Yes, this could be one of the issues causing a car to shimmy.  A loose ball in the front wishbone can be one of the causes of front shimmy.  The front end caster (5 degrees) is dependent on the exact position […]

Two-Tooth Steering Column

One day while I was at Snyder’s Antique Auto Parts, a fellow asked me how hard it was to adjust the steering box.  It seems he was rebuilding a two-tooth box.  I told him, “There’s nothing to it.  Just follow the directions in the Model A Ford Mechanics Handbook.”  This brought laughs from those in […]

Enough Grease?

How can you tell if you get enough grease in the universal joint?  Remove one of the speedometer gear bolts and fill until you see grease come out.  Replace the bolt. This article was printed in the September/October 2010 issue of the “A” Quail Call by AJ Pennington.

Brake Adjustment

When walking in parking lots, we look at a lot of A’s.  One thing I notice is the front actuating arms on the brakes.  Too often they are straight up or even leaned back a little.  This means there are no front brakes because the travel is gone. I was taught to have a 15 […]

Proper Muffler Clamp Installation

If like me you have lost points during the judging process on your muffler clamps, here is the proper tail pipe clamp installation.  The tail pipe clamp was painted black, with a hex bolt, castellated nut and cotter key.  Make sure that the tail pipe is correctly clamped to the frame and not over tightened […]

Model “A” Wheels

All Model “A” wheels have the same bolt pattern. All hubs have the matching stud pattern. Unfortunately, it may be disastrous if you install the early 1928 AR wheels on later hubs or the later 21” or 19” wheels on the early AR hubs. Check page 328 of your Model A Service Bulletins. This book […]
