Great engine and a great job bringing it back to it's former glory and then some. I also like your workshop accessory board.

Very well done...!!!

Job well done. Your 55 came out aces. Thanks for the share; glad to hear others have prolonged fights with Jensen sight glass.

Very nicely done ... she's a beauty now for certain and for sure!

Yes, those porthole sightglass nuts can be a real PITA to be sure, but it seems you let logic and patience rule the day and won in the end.

I also love the Jensen 55 for its self starting and smooth even power distribution. Certainly a wonderful engine and one of Jensen's finest IMHO.

Nice save, runs well  8)  and can't believe how crusty the sight glass was  :o


Also like how you raised the lineshaft, I'm assuming for the larger pulley?

Bought this Jensen #55 at the Cabin Fever show a few years ago and thought it was way past time to get it cleaned up and running.  It looked in good shape, except the previous owner must have had some seriously hard water.

I won't bore the knowledgeable people here with the step-by-step account of the process, but the sight glass nut did prove to be a complete pain in the butt to remove.  Eventually after vinegar, CLR, heat (cracked the glass) and a oil soak overnight the nut finally relented and came out without any damage.  After that, everything went well.

The based was stripped as the lacquer or shellac was starting to craze and bubble and of course the firebox needed painted.  I was able to complete the entire project over the Memorial Day weekend with a full day allowed for the paint and polyurethane to dry.

It came out looking nice as they always do.  The engine was a bit sticky at first, but after I got some oil worked into it and ran through a few boilers of steam it was running nicely.  The gimmick of these engines is that with two cylinders they are always self starting and they also run very smoothly at slow speeds.  I really like it!  In the future I will be adding a PM Research #7 to my stash of kits as it is a very similar engine.

Here's a video of the restored #55 running my Wilesco #100 workshop
