Re: Mile-o-matic servo piston seal question

My guess is that they are selling a kit that is one size fits all or at least the end user hopes it will be. Square cross section o-rings are not common like round cross section types are. Hopefully...

Re: Purpose of dual points?

The points cam & breaker gap is what sets the opening and closing of the breaker points. How far open the cam lobe lifts the breaker points off the seat has a lot to do with the dwell time. Lobe...

Re: Hard turning with new pistons

The center main tends to wear faster than the others. If it had a good bit of wear then de-shimming can set up a pressure on the center main that is trying to pull the crankshaft off center a bit....

Re: Skip's rebuilt coils

With most folks, it matters very little on what his procedure or materials are. The bottom line is how well they work and how long they last. All other factors are immaterial. I'm sure most folks...

Re: Electric short somewhere

The old resin and cloth covered wire that was used in the early Ford days can crumble to dust after so much time. It's not unusual to have opens or broken wires, shorts to ground, and cross shorting...

Re: Wandering

The caster on the model A vehicles was fixed from the factory but is can change with heavy use and lots of bumpy roads over the years. Accidents can bend the axle and as was mentioned, the radius rod...

Re: Purpose of dual points?

In a dual point system with only one coil, one set of points opens or breaks the circuit and the other set closes the circuit with a very marginal amount of overlap. The Ford/Mallory V8 distributor...

Re: Front Fenders Hit the Shocks?

Ford used Who-Die shocks for many years so there could be different shocks on the vehicle. Many of the later shocks after 1932 have different mounting hole configurations. There were also aftermarket...

Re: Headliner question #2

They are referred to as listings. Some are looped for a wire to go through and some are just a strip of fabric to tack or staple to a wood bow or tack strip. Sometimes they are all looped to make...

Re: Front Fenders Hit the Shocks?

I don't think the shock itself lends itself to problematic assembly procedures but a person needs to observe right and left insallations in correct placement on the frame. There should not be any...

Re: 10 spline pinion 34 v 35 difference?

They used the same center section for a long time but there were variations with the axle bells and the bearings for the differential carrier bearings in the earlier units. All this stuff can make...

Re: Dual Condensers?

The model A ignition system pretty well shows that Ford Motors was still on the low side of the technological ladder at the time. Their use of the breaker side of the circuit for the ignition switch...

Re: Help! - 1955 Thunderbird 6V (ground-neg.) generator not charging

Re: Skip's rebuilt coils

When a person is rewinding a coil whether it's for ignition, a horn, or a relay, they generally count the number of turns when they disassemble so they can replicate the number of turns with the...

Re: 10 spline pinion 34 v 35 difference?

Most 1935 to 1948 gear sets that are available these days are 6-spline. This is what necessitates the adapters for cars that still had 10-spline. Those early ones that came out for use with the V8...

Re: Stock 57 Fairlane 500

1957 was a good year for the small Y-blocks. Ford improved the engine a lot by just replacing the old Load-O-Matic carburetor and ignition set up. There were other improvements as well but the engine...

Re: Anyone use these drill/tap all in one?

A lot of the bores I need to tap have a bottom. Sometimes I even need a bottoming tap. I'm not a big fan of the two flute design taps either but they would work for some applications. I like to go...

Re: Assembling 68C Belt Rail and Package Tray

Re: counter weights are they needed?

The heavier flywheel allows for lower rpm in operation. Low rpm engines have less problems with higher harmonics. Counterweights allow for a wider rpm band and reduce the need for a heavy flywheel....

Re: Follow up to the "counter weight" thread.

If they were planning for obsolescence, they didn't do a very good job of it. There are still a lot of roadworthy model As out there.

The model A engine as developed for automobile production was...

Re: Loud Noise when car decellerates while i n first and second gears

Decelerating is generally when the power train is unloaded and starts to push back the other way due to engine braking. Any thrust loading in the transmission changes from thrusting some aft to...

Re: Car jumps out of gear

The model A transmission is about as simple as they get. The gears are all straight cut so they don't thrust as much as the later Ford transmissions when the unit changes from load to engine braking...
