Keaton 464 #1 Posted May 23, 2024 i was wondering if someone could date this engine for me it is a replacement engine, on my RJ 59 the block is blue and the fan shroud is red the tag says K91 T E020100 and the spec no is 316270 there is a picture also, that tag is in great condition, thanks -Keaton 1 Share this post Link to post Share on other sites
Pullstart 64,911 #2 Posted May 23, 2024 The blue replacement engines had their own shrouds too. My guess is the red shroud came with the tractor. 1 Share this post Link to post Share on other sites
gwest_ca-(File Mod) 11,281 #3 Posted May 23, 2024 E engines were made in 1969. The charts are in the first pages of the Kohler service manuals. The spec may be 31627C https://www.partstree.com/models/k91-31627-kohler-k-series-engine-made-for-merry-mfg-4hp-3kw Share this post Link to post Share on other sites
Keaton 464 #4 Posted May 24, 2024 @Pullstart I thought it was a 1961 but was not Shure, is there anything on the block to date it? or is it just the fan shroud, and I thought that shroud was also the original engine but believe I'm wrong Share this post Link to post Share on other sites

The tin has all the details. Share this post Link to post Share on other sites
