Another Palmer comes back to New England for a while anyway
Here are some before pics of a Palmer PNR1 that I am going to restore for Dick Day.
This should be a real nice engine when done as the cylinder is NOS and the head appears to have never been in salt water.
However it did create quite a fuss in Cos Cob tryng to get out of the car. I finally yelled back at it "there isn't anything left you want to see" not unless you like condos and other funny looking modern stuff.

What beauty Ernie.
Looking at the complicated castings and designs of these engines I really wonder about the cost of manufacture vs. the sale prices. |

Richard,
You asked for pics of the restoration. Here are a couple just to perk your curiosity. I have a bunch that I will post as I have time. It is green because the NOS cylinder was green not blue-gray

Richard, Not many PNR engines were sold. The PNR did not have a counter balanced crankshaft and its bore was 5" with the ZR 5-1/2". The PNR was intended to use up a large in house stock of NR parts which had been in production since Dec 1912.
Many of the 1962 ZR parts such as the oil pump, bronze camshaft bearings, valve push rod guides, push rods lube oil sight glass etc. date back to 1912.
The ZR-1 with its counter balanced crankshaft cost $35.00 more than the PNR and not many PNR were sold.
I have records of 63 known ZR-1. There are 9 known PNR-1. The PNR-1 and ZR-1 for all practical purposes look the same. Even with the counterbalance crankshaft the ZR-1 was typically run not much more than 600 RPM by the working watermen as it stressed the hull badly to the point the planked hull lasted about ten years before being replaced. |

Ernie, Thanks for the rebuilt photos and any others that you post!
Dick, Thanks for your always welcomed info on these great old Palmer Engines.
These are photos of an NL1 that i've had for several yrs, it came with the new or recasted cylinder ? the paint is original and is quite greenish rather than gray ? on the cylinder flange you can see the paint color that I had electronically duplicate the the original? would like to find the magneto gear and a support bracket for a magneto, will try to get this one redone soon.
---------
This is a ZR1 that I rebuilt recently.
----------
An old Sponge Diving museum had closed for lack of funds recently here in florida that had a 1941
ZR1 in its inventory that had been taken all apart and it came into my hands, a project I look forward to rebuilding. these are photos of the tags, will post others as rebuild gets underway !

More Pics
Cam Bearing on mandrel to true up mounting flange so it is 90 deg to the actual bearing
I will paint the head and flywheel as soon as the humidity goes away. It had to be 100 percent plus here today.

Nice looking work Ernie and Richard.
Richard has comes up with a new serial number which is filling in a small gap. I have a listing for a ZR-1 2908037. Richards ZR-1 2983041 is 750 engines up. I have a ZR-1 3325846 which is 3428 engines up from 1941. This particular tag is also marked 3-1-46 The only tag so marked in over 400 serial number tags. This engine happens to be in the wood shop at Calvert Marine Museum. Now Palmer made about 3000 lifeboat engines based on the LLH for the Maritime commission during WWII. In addition they made 200 engines based on the GW-6 for the US.Navy to be used for torpedo recovery vehicles. In effect it seems to me these serial numbers track with what is current knowledge from documents published by The Palmer Engine Co. |

I forgot to add Palmer made 200 of the SK-75 model for the Russian’s under the WWII Lend lease program. This engine was approx. 75 HSP at 1000-1400 RPM, 22” dia. 3 Blade prop, weighed 1900 lbs. This engine was one of the series of engines Julius Ulrich chief Engineer 1919-1957/58 designed. The YT-1 1921 was his first and the YT-2 Came along in 1924. He designed a number of big block engines which never sold as well in the 1930s as the truck and automotive conversions like the Ford V-8. His engines were not popular in the depression years due to their high cost.
The SK-75 was basically a 6 cylinder gasoline engine which Palmer at the request of the Russians modified the carburetor manifold to accommodate a connection to a gas producer which burned wood chips. In that regard Palmer supplied a clutch and flat belt drive pulley centered on the flywheel housing. The function this provided for was driving the cord wood saw to cut up the wood which was burned in the gas producer. Start on gasoline and switch to producer gas once it was producing fuel for the engine. Palmer never heard if the engine ever reached Russia much less how well did they perform. Palmer did not supply the gas producer.
Note adding this 200 engines brings the total 1941 to 1946 to 3400. I wonder what the remaining 28 engines were. |
