Johnson TN Stuck, where to start?

[wanderlustjake]

I just picked up a Johnson TN last night. If I try to spin the prop, it has zero movement but I can feel just a hair of movement (like a gnat hair) grasping the flywheel. It was the seller’s Dad’s and he knew nothing about it. Is there anything with the neutral clutch that could lock it up? Just curious if there are any “high flyers” to check out first on these motors?

Thank you.

dropping te GC gets complicated cause you need to disconnect the neutral cable… try popping the fw as a starting point cause you need to inspect the coils anyway (likely all cracked)

you will need an impeller so dropping the GC can come later anyway and… maybe the clutch is broken diagram TN GC1 ..

. and this will tell you if the blockage is above …or below in the GC 🙂

shoot some wd40 in the cylinders just is case but stuck rings would probably stop ANY movement worth a try

next could be the cyl. head to inspect the cyl walls and pistons

after the mechanics are fixed comes the carb …

It wouldn’t take long to remove the prop and cap off the gear case
to see if it’s full of rust instead of grease.

Prepare to be boarded!

It’s a TN25. Thank you, as soon as I have some time I am going to dive in on it.

as a aomci member you would have access to download the 400 or so pages of the johnson repair manul covering oldies… from your TN td and up to late 50s

it is in the MEMBERS ONLY section under INNER SANCTUM…LIBRARY…Garry Spencer’S drop box…. down the file is a RED BOOK…. where the pictures provided come from 🙂
