Flip top jack

Post by Humblej » Mon Feb 18, 2019 6:51 pm

Was at the Benson Ford Research Center today, found the jack drawings. The pressed steel jack changed to the flip top design in drawing dated August 1925. The part number remained the same. Applicability: "all T chassis".

Thanks Jeff ! Do you remember if the flip part had a hole, or no hole on the side?

Thanks , I just stole this from the model A site. They say the “no hole” is model T. It’s nice to know the date now !

With the suspension being lowered on the 26-27, the date, more or less speaks for itself. The non-flip type is a mystery to me. They look too short for use on a 25 and bit too tall for use on a 26-27.

Here are all that I know of. It would be nice to have aprox dates with them. The model A historians have pinned their jacks down to the month.

Info researched by Trent Boggess

On 9/10/24 the pressed steel jack design was adopted.
The car jack is 8-5/8” tall and the base is 4-1/2” across.
The handle was made a separate part and carried the
factory symbol number T-3391-B.


...the old style screw jacks were declared
obsolete on 9/13/24. It appears that the pressed steel
design were the standard issue jacks on the 1925 models.
About a year later on 8/4/25 the design of the jacks was
revised. On both the car and truck jacks a two-inch
extension was added to the top of the jack.

And that flip top jack is well suited as the 'universal jack' as it can be used with the 'flip' folded over if the front tire is flat on the ground, either style of T's early or late. With the flip over......that jack is the lowest version to fit under the T front axle ;)

The date for the hole addition in the flip top is probably buried somewhere the Walker Jack Co. files.
It doesn't seem to serve any Ford purpose so it's doubtful they made it a requirement.

While I learned some time ago that the hole was in the Model A jack, I have never been able to find a reason for that hole.

Never been able to find the reason they're (MAFCA) so sure the hole was never there prior to the 28 model year either.

Bill C., the lower suspension on the later cars would have nothing to do with the jacks. Tire size would though. JMHO Dave
1925 mostly original coupe.

So could raising the front spindles without changing the tire diameter.

From the encyclopedia:

"The “improved” Fords were lower in height than the previous models. This height reduction was accomplished by not only reducing the height of the bodies themselves (except for the Fordor) but also by lowering the frame by a redesign of the front spindles, and a reduction of the crown in the front spring."
