Info on My Johnson 5.5

[fyr259]

I have a old johnson 5.5 hp model cd-13 ser #1371610<br /><br />2 Questions<br /><br />1, What year is it, I'm guessing 55 or 56<br /><br />2, I need to remove the flywheel and it will not come off. I read on another post to use a harmonic balance puller with 1/4-20 grade 8 bolts and pull from the 3 holes near the center nut<br /><br />Any help would be great<br /><br />thanks mike

Welcome to Iboats, mike!<br />Johnson CD-13<br />Year: 1956<br />HP: 5.5<br />WOT RPM: 4000<br />Displacement: 8.84 cubic inches<br />Cylinders: 2<br />Weight: 51 lbs<br />Gear ratio: 15:26<br />Lower unit oil: OMC/BRP HiVis or equivilant 90w outboard gearcase oil.<br />Fuel/Oil mix ratio: 24:1 87 octane gas to TC-W3 rated outboard oil.<br />Spark plugs: Champion J6C gapped at .030"<br />Tom Travis' excellent 5.5hp site<br />Catalog<br />From the Old OMC Site<br /><br />2) Yup, that's how you do yours too. Grade 8 bolts arn't necessary for that smaller flywheel. But where it's a tool, why not get something decent eh?

No trouble! Tom's method of removing the flywheel works too. I just don't like beating on the end of the crankshaft with a hammer.

I just got it off, you need to get 4" long 1/4-20 bolts, I bought 2"s any it too short for the puller.<br /><br />Now I need coils and condensers<br /><br />Thanks again<br /><br />Mike

No trouble! I should have mentioned that about the bolts.<br />Personally, I find the German made aftermarket (18-5181) coils superior to the OEM ones. Good luck with it!
