tn28 flywheel removal, what am i doing wrong

[greenygreen]

i cant seem to get the flywheel off. using harmonic balancer with soft hammer tapping while lifting up. How mean do ya have to get with these things?

Having a good deal of pressure applied to the puller's center shaft, and prying upwards on the flywheel so as to eliminate any play..... BELT the top of that center shaft hard with a good size hammer... NOT a gentle tap!

Make sure those ht bolts are in the proper depth.
I do as suggested above.
Sometimes i torque them a bit more then leave it over night, often you will hear a loud pop from the workshop during the night as it comes free

That all looks good, you have to put a great deal of pressure on your bolts, almost to the point of pulling the threads, then WHACK it good with a dead blow hammer, not ***** hit, it will POP.
The amount of torque needed you won't be able to apply by holding that strap, you need a prybar between the center bolt and one of other 3 or a huge cresent on the one square of the puller, then you can pull some torque.

shazamm . i thought somethin broke and took the puller off and she lifted right off. alot more pressure on it than i thought. So now i have an ohm meter so i have to find point of failure. no spark at top cylinder. now im really lost!

Thats a good thing to happen unexpectedly.
Ive bent ht bolts undoing flywheels and they a still stuck.
Has that model two coils?
If so switch the wires over and see if the problem changes cylinder.
Also a bad sparkplug wont spark- quite common no matter what they look like externally

Re: tn28 flywheel removal, what am i doing wrong

yes it has two coils. i was told they were new but i dont think new is right word. they have an M stamped on side. any ways i confirmed the plug was good and there was no spark at end of wire

Re: tn28 flywheel removal, what am i doing wrong

can you swap the leads over and coils and retry?
Do the magnets in the flywheel look ok?

Re: tn28 flywheel removal, what am i doing wrong

idk it all loooks so confusing.. idk where to start. i noticed inside the flywheel was slightly grinding on throttle lever in one place

 

[Bosunsmate]

Re: tn28 flywheel removal, what am i doing wrong

yeah dont change those over.
Is the one on the left burnt on its top arm?

 

[greenygreen]

Re: tn28 flywheel removal, what am i doing wrong

its not near as clean as it looked thru peep hole. got some cleaning to do

 

[Bosunsmate]

Re: tn28 flywheel removal, what am i doing wrong

Rotate the engine slowly
Are those points ok?
not pitted?

 

[greenygreen]

Re: tn28 flywheel removal, what am i doing wrong

it is burnt i think. looks kinda funny. maybe where it was grinding.. throttle wouldnt stay up by itself

Hopefully will give you a visual and help you some.

Sorry the camera and video edit software was not all that great. It is very hard to see the spark when I am checking with the spark checker, but in the end I get both set of spark plugs to fire even though you may not be see them. Anyway, I think you will get a good idea how to work on OMC ignition from 1950 to 1973. I know the videos are a little long, so I had to break each segment into 10 min. I am not that good a videoing or editing.



Cheers, hope y'all have fun working on old outboards!!!

Re: tn28 flywheel removal, what am i doing wrong

Can you get a photo of it?
Something gone on there- certainly isnt new!

 

[greenygreen]

Re: tn28 flywheel removal, what am i doing wrong

i think they look ok. just a little loose junk around

 

[greenygreen]

Re: tn28 flywheel removal, what am i doing wrong

here is a little closer

 

[Bosunsmate]

Re: tn28 flywheel removal, what am i doing wrong

Doesnt look too bad, but im not sure, someone else might know.
Is that the coil to the bad cylinder?

Not burnt?

Re: tn28 flywheel removal, what am i doing wrong

im not sure. maybe cajuncooks video links is gonna help me help myself. im gonna check em out in full and see if i can figure out where to stick this ohm meter lol..
