Motor Mounts

Unknown

Attachments :

One of the items that needed to be fabricated before installing the new

'26 motor were motor mounts. When we removed the old '29 motor out of the '26

car, a set of what look to be original Hudson motor mounts was recovered. I

believe them to be original because they are very regular in appearance and

made of a tough fiber material. The parts book for the '26 mentions that the

motor mounts were a fiber material.

The originals measured 3/16" thick and are VERY tough and inflexible.

They could have offered little in the way of cushioning or vibration

isolation. It's a good thing that the counterbalanced Super Six engines ran

so smoothly!

The front mounts (the ones with the single holes) were worn down much

more than the rears and even allowed metal to metal contact between the

crankcase mounting ears and the chassis steel mounts. Replacement seemed wise.

Press Kale of K-Gap suggested using his mud flap material for radiator

mounts and that same material was used to make new motor mounts also. The

material is vulcanized hard rubber reinforced by a core of cloth. It is an

1/8" thick. While still pretty stiff, it is much more flexible that the

ancient fiber originals.

To make the new mounts, I held a sheet of material underneath the

mounting ears of a Super Six motor a traced around with a pen. Pencil made a

poor impression. The material was cut by ordinary scissors. After cutting out

a front and a rear master, the new cutouts were used to make three more front

and rear profiles. Contact cement was used to bond two pieces together into a

1/4" thick composite. Now there were two rear and two front motor mounts, but

the looked a little ragged around the edges.

To my surprise, the old bench grinder proved the perfect tool for

smoothing the rough edges. The two fronts were held together and touched to

the wheel which put a fine professional looking edge on the rubber. Both

sides look alike when separated off the wheel. The rears were done the same

way.

All that was left was to drill the holes. My biggest drill is a 1/2", the

exact size of the engine mount bolt. To make the holes, the two front mounts

were held together by hand under one of the fiber originals and the hole

bored through with a drill press. The rears were bored the same way. The

holes are a snug fit on the bolts, but that turned out to be not all bad.

When the engine mount bolts were run up from the bottom, the new rubber

engine mounts held them neatly in place.

The overall result looks pretty nice. With the stock installation, the

mounts were completely invisible. In this one, a bit of rubber shows all

around helping to support the rubber supporting the weight of the motor.

One pic is attached to this post, two have been uploaded to the Files

section in the folder "Super Six Motor Mounts." I'll shoot two more pics of

the mounts installed this coming weekend and post them to the same folder.
