Wooldridge Family

I am always looking for any information or parts for 1914 Apperson Jackrabbit.

Apperson Engine and Parts Pictures

These are a few pictures of the Apperson engine removal and tear down. Also pictures of the parts I either had to repair or have made.

The Apperson engine was in worst shape than I though so it is good I am rebuilding it now. If I had waited the next failure could have ruined the engine beyond repair.

I am updating all seals from felt to modern type so I should not have as many leaks as before.

Engine Removal Engine coming out of the Apperson.
Engine Going In Cart Engine being put in cart for transport.
Ready To Go Engine loaded and ready to Go to St. Pete.
At engine Shop Removed from cart at St Pete.
Number One Main Bearing Number one main was cracked in half only held together by babbitt.
Wore Out Engine Camshafts were in bad shape.
Number One Main Number one main cap removed.
Camshaft The camshaft lobes had depressions wore in them.
Rear Main The rear main bearing cap. They told me that the Apperson engine had over 6 pounds of babbitt enough to do 10 normal engine such as model "T's" and "A's" engines.
Internal Parts Look at the 100 years of gunk.
Rod I guess light showing through is not good ;-) ;-)
Valves One of the valves. Note that they are flat seal no tapers like on modern valves. They are going to install new tapered valves.
One of The Jugs The valve seat will be tapered to take the new tapered vales.
Cracked Jug At least to of the jugs were cracked. They will be repaired.
Parts Glad I do not have to remember where it all goes,
More Parts Hugh pistons 4 ½ X 5 bore and stroke.
The Block The block is aluminum.
Crank The crank was pitted as was the camshafts.
Line Boring All set up for line boring.
Number one Cap This block of aluminum will be the new number one main bearing cap.
Jug One of the jugs need to be sleeved. The sleeve is in the white paper.
Rear Pinion Shaft See the repair of center punching the shaft.
Pinion Shaft Interesting repair, but as with any car even now you do what you have to do to keep it running. I am having the shaft built up and turned down to the original specs.
Rear Pinion Bearing It hard to see but the inter race is wore and enlarged, which is why the repair in the last picture was done.
Pinion Seal Retainer There was no seal in the seal retainer when I got it out. As you can see it came out in pieces.
Seal Retainer The original seal was felt. I am replacing all seal with modern seals.
New Seal Retainer I had to have a new seal retainer made.
New Seal Retainer New modern seal will be installed in the new retainer.
Damaged Rear Torsion Bar Parts The lower nut on the shaft that held the torsion bar to the rear end was sheared off at some point in the Apperson's history. In doing so it also bent the front holder and the torsion bar which had to be straightened.
New Shaft This is the new shaft I had machined.
Transmission Transmission cleaned and flush out and ready to go. As with the rest of the seals on the Apperson the front and rear bearing seals were missing. I have installed modern seals so I hope to not have as many leaks as before.
