Installed and locked the cam and balance shaft weights. They are located behind the flywheel. The flywheel is a SAE#1 28 inch diameter The flywheel ring gear has 128 teeth. It is chamfered left and right on each tooth. Get some help installing it. It weighs 220 lbs. With all the weight on the crankshaft it .follows through quite well when i hand crank it.

The engine is not quite ready to fire up yet. As i have never hand cranked a 1-71 before i am not sure how much resistance i should feel. There is a little more with the compression release off. It seems to me there should be more. I would feel better if i removed the cylinder head and did a valve job. Before i do that i would like to find a head gasket. Have done a little searching and come up empty. Any help out there would be appreciated. Aloha AL

Working on the blower. Installed sleeves on the rotor shafts and seals in the end plates. The white plastic is a installation tool to protect the seals when installing the rotors. It pops out the other side when the rotor is installedClick image for larger version

Assemble, and adjust blower clearances. Adjustment done by adding shims between the back of the gears and the thrust double ball bearings. The clearance between the rotors is .008 thousands The other end of the blower has non loading roller bearings.Click image for larger version

Shame about the radiator, any updates on whether or not you found someone to repair it?

Sending it to Honolulu to an old radiator shop. They may be able to help me. The old days of repairing are a thing of the past.

The original oil bath air cleaner was pretty much wasted. Found a very close replacement on EBAY which the seller said was used on 1930"s 1940"s 1950"s Chrysler, Dodge,Plymouth and DeSotos. The oil separator element on my 1-71 air cleaner has mesh in it. The one i got from EBAY had horse hair. They are very similar so i am going to use the metal one from the 1-71. 80 year old horse hair is probably at the end Click image for larger version

Very nice find Al! My 1-71 also has a horsehair filter element. I usually do not ask to see what is going on inside of the air cleaner since so many of these engines are missing their original air filter. I can say that yours is the first I have seen with a steel ribbon element in it. Looks like it will do a fine job. Perhaps one can make a new element out of several 53 series breathers worth of material...The horsehair in my filter is shot. It definitely has a shelf life! I am so glad you found a suitable filter housing for your museum quality engine restoration. Let me know how the radiator shop makes out with your radiator. I may have to send mine to Hawaii for repair

Check out horse hair on line. It`s ready available. It should be easy to pull out the old and replace it. Sent my air cleaner to have it powder coated. There was a remnant of a decal on the top lid. I found the original reproduction from a company in San Diego [ Rubber The Right Way] Part # DA0111. 6 bucks.Click image for larger version

The fresh water pump is pretty simple. Disassembly requires using a bench press pushing the shaft and bearing from the impeller. In the center of the pump housing is a raised boss that acts as a sealing surface for the carbon spring loaded seal. My shaft has some pitting where the seal and shaft make contact. {PLAN 1} Find a new shaft and impeller assembly. {Plan 2} Spray weld shaft and machine to original size. The impeller and seal were made as an assembly. I have seen similar mechanical seals used in other pumps. If i can find a new seal assembly i could fit into my impeller. Does anyone know the shaft size of a 2-71 water pump? It may have the same seal. The bearing is a sealed and i can get it locally.Click image for larger version

Had the 10 amp battery charging generator restored and made operational by Whatcom Electric Co in Bellingham Wa. They are a good source for vintage generator and starter repair. Good work for a fair price. It also didn`t hurt that the owner is my brother in laws brother.Click image for larger version
