[Boonie]

Ok so here we go. Tightened this puller up and gave it two moderate blows with my hammer. Before and after pictures.

Mumbles nailed it! No damage to the crank.
Now I need to find a new flywheel.
RD 10 part # 580-109. If anybody has a lead I would appreciate it.

Here’s one on ebay.

The 3 HP LightTwin flywheel had some changes from year to year in the 1950’s -1960’s. You need the right one or your recoil starter will not match up. Post a wanted ad in the classifieds, and put in the year, model number and equivalent model for a Johnson of the same year. I’ve got a couple parts motors around that might have the one you are looking for, but I can’t get to them in the winter. I have one flywheel I think I can get to. I’ll look tomorrow. If I find it, I’ll take a pic and send you a private message. I can’t check the model number because most of the rest of that motor is on top of my flagpole. I think it’s a 1954 or 1955 Johnson if I remember right. I removed the flywheel to make it lighter.

If you have a photo of it before it broke, that would help.

In your post with the model number RD-10, did you mean to saw JW-10? AN RD is a 25 HP. Also LightTwin is an Evinrude with a different model number format: “JW-(two digit number)”.

Maybe I’m confused here – the post title says LightTwin headgasget – did it somehow switch to a Big Twin?

Yes Dave. I apoligize for the confusion. I’m new to this forum and am working on four different projects at one time.
I’ll try to clean it up.

I thought you must have meant JW but I happened to be looking at an RD-10 motor recently so I got confused myself!

A lot of us have done that as rookies on the forum here. The solution is easy – in the future, start a new message string for each motor and for each different problem with a motor.

Glad to have another active member on the forum!

The motor in the photo of the broken flywheel is an RD. The original JW head gasket question got answered earlier.

Where abouts in Canada are you located? I know I used to have a flywheel here off a ’54 Big Twin Electric but I’m not sure if I still have it.
