Need help in installing needles and liners in 1.5 hp johnson outboard

[vito91256]

I have a johnson 1.5 hp outboard and I do not know how to install the needles and liners on the connecting rod. Please help.
I need to install them on both the sides of the connecting rod.

Use assembly grease to hold them in place , and make sure you have all of them. I have a service manual here somewhere. I will see if I can find it...

Vito, Clean those needles in a solvent to take off the wax that those pieces were packed with. As pointed out an installation grease will hold needles in place. I use Vasaline. Others may suggest something else, but you get the idea. Ed

I have them clean but how do you press the liners on to the needles and rod end , since the needles are slightly longer than the liners.

Also how do you center the liner when you have 15 needles on the rod end.

After cleaning all of the needles, lay them out on a clean cloth or white paper towel. There should be 29 of them. I like to lay them out in little piles of five with one pile of four left over. If you don’t have proper needle bearing grease to hold them in place, Vaseline will work and is better than grease as it will get washed out as soon as the motor is started. Grease can linger and plug the oil holes. If it’s hot out, stick the Vaseline in the fridge for a while to stiffen it up.

Coat the rod liner and lay in about half of the needles before snugging it up to the crank. Now the crank journal can be coated and the rest of the needles laid in place on the journal. A set of tweezers comes in handy for doing this. Just make sure the liners are installed so the cap can be installed correctly with the index marks lined up and also make sure all 29 needles are accounted for. Dropping one into the motor and not realising it could be disastrous.

Ouch!! That piston looks like it had a rough day.

That doesn’t do the cylinder wall any good either . . .
I am always amazed by Mumbles "Don’t let this happen to you" illustrations . . . 😆
