Steve S. 2 Posted Monday at 05:06 PM My recently purchased TD9 was located at a sawmill. At the back of the property is sitting an International gas start diesel powerplant. I assume that it once powered the sawmill. No one knows anything about it. I think they would like to see it leave the property. It is a six cylinder with a Bosch fuel pump. It appears to be complete. It is located near Tunkhannock PA. If anyone has interest, I can find out more. Quote Share this post Link to post Share on other sites
Redwood 2 Posted Monday at 06:26 PM Appears to be a UD18 stationary engine. Could you please post a photo of the back side of the engine? Gene Quote Share this post Link to post Share on other sites

hardtail 279 Posted Tuesday at 12:42 AM It is a UD18, looks like an earlier version with the filter arrangement, only one visible exhaust stack kind of odd? Quote Share this post Link to post Share on other sites
PA Shovel 0 Posted Wednesday at 12:03 AM What are the differences between the UD-18, and UD-16 ? Quote Share this post Link to post Share on other sites
hardtail 279 Posted Wednesday at 12:08 AM UD18 691 probably came out 1939, only of only gas starts that has injection pump driven by shaft and coupling UD16 554 came out around and I’m guessing 1958, you see a very similar looking engine in early graders and other but likely UD 525 HP wise almost the same as last 18’s, hp numbers climbed over the years, exhaust manifold differences between the 2, dull stacker as CC would say Quote Share this post Link to post Share on other sites
PA Shovel 0 Posted Thursday at 10:13 PM Hardtail: Thanks, that was helpful. I have/had a UD-16 in my Koehring shovel, although the engine is sitting my shop as it got some water into a few of the cylinders and I'm not having much luck finding internal parts. Was not sure if the 18 might be a parts unit for my 16. The other interesting part of your information is that indicate that the UD-16 came out in 1958 ish. My shovel was built in 1953, and just recently I purchased a Koehring parts manual. After some reading, I learned that the Koehring 304 was offered with either CAT power or a UD-14 when manufactured new. This seems to confirm that my shovel was re-powered at some point with the larger UD-16. Quote Share this post Link to post Share on other sites
Redwood 2 Posted Thursday at 10:30 PM PA, Keep in mind that the UD-16 is the 6 cylinder version of the UD/TD-9 engine so they share a lot of common parts. Gene Quote Share this post Link to post Share on other sites
