can you setup the timing without the engine running on a 115hp

[comet424]

hi i havent gotten my block back from the machine shop so i just asking questions ahead of time
i read online you test the timing when engine is running but if its out of wack it might damage things.. and i having new pistons put in so dont want that

now on my 115 chrysler engine i set the timing of the engine with the engine off and throttle forward and you pressed on the belt and the cdi box when you pressed on the belt causes it to spark the coil (but didnt have it hooked up just to a mulit meter so id get 12 volts on my multimeter and it was set like 32 degrees or something it lined up with the sticker on the fly wheel... but how do you guys do it with this engine... is there any good videos also to watch so i can get a grasp on it before i get it back and set it up

so i wanted to know if you can do the same like with the chrysler engine with this engine too something similar. like turning the flywheell a little

What motor?

 

[comet424]

my bad forgot to post. it be on a 1984 evinrude i been going over the selco book and i just getting a bit confused so figured id ask here for better explanation and different way of timing also tells me to refer to the tune up charts for the idle speed i cant find it in this selco book lol.... but its nto ready to run yet... i just wanna make sure i know how to set it up before i tackle it

 

[comet424]

finally found the tune up spec page idling at 6-700 but WOT only up to 5500rpm figure id scream louder then that

Look in the Top Secret Files at the beginning of this forum for setting timing without motor running. Article by Joe Reeves.

ok reading it a few times and the book says the maximum advance BTDC is 2 with a cricle around it so i guessing that 2 degree and is that at -2 degree mark on the fly wheel?? since it be 2-4 = -2 mark.. or are you minusing it from the 12 degree mark

and is a spark tester a spark plug tester it doesnt say how its wired up though how you do that?


so also reading the selco book talks about you turn the engine clockwise by hand and use a dial turn it to just as it touchs the dial and that should be 12 degress but is that right or should it be when it hits TDC and that be 0.... as it says once it hits the crown of the head the dial. which would be just touching it slightly.... you turn the flywheel backwards till it touches again but that can be alot as it be going back down.....

can you detail it a bit better?? so i know then that the pointer mark arrow is set in the right position...and then i can go with this 12 degree mark etc

Not to be insulting, but I think you should throw that seloc book away and get an OMC Factory Service Manual. I had one of those seloc manuals once and threw it away.

where do i get one of those books the marina could only get me a selco book and here is what its written this is how i getting confused

1. a special tool or dial indicator is required to accuratley make this adjustment. remove all spark plugs from the block. Install the special tool or dial indicator into No 1 (top starboard bank) spark plug opening.

2. Rotate the flywheel clockwise untill the piston crown makes contact with the dial indicator or the special tool at 12 TDc. Lock the tool or dial indicator. at that point scribe a mark on the flywheel in line with the pointer . Slowly roate the flywheel counterclockwise until the piston again makes contact with the dial or special tool.

3.scribe another mark on the flywheel in line with the pointer measure the distace between the 2 marks just scribbed on the flywheel. the midway point between the 2 marks is top dead center. loose then screw and adjust the pointer to align with the midway point between the 2 marks


now how i confused is you turn the flywheel till it just barley touchs the dial and that is your 12 degree mark and then you turn it backwards till it touchs again.. but that could be 2 feet right as now your turn it back down not forward so thats a hard way to divide by 2 be a foot say from the 12 degree mark....

as it does have a 12 degree mark on the flywheel but i wanna make it precise though so i confused from this damn manual

Nothing sets at 12 degrees on your motor, use the Seloc as toilet paper or fire starting material.

 

[comet424]

ok so what do i do step by step then or a link or a video that shows what to do? so once i get the other half of t he block back from the machine shop i can make sure that this engine is set right as when i bought it it neve ran right at first so i wanna make sure it runs right out of the get go

 

[racerone]

??????-Get a factory manual and read tune-up section 4 times before trying to adjust anything at all.-------So far it appears that it is all over your head just like the ocean.------Only adjust maximum timing.---Nothing is set at 12 degrees on that motor .-Sorry for being blunt and to the point here.

 

[comet424]

alright ill try to find a omc manual ill try a couple other marinas... and well i just following what the selco book says about setting it to 12 degrees which wasnt making sense as i wanna know if the pointer is in the right spot as well since this engine has been worked on in the past so i just wanting to make sure its lined up correctly... but ill try to find the omc company for a manual

 

[emdsapmgr]

Get an original factory manual from the guys that print the manuals for all Johnson, Evinrudes: Ken Cook co. See this website: outboardbooks.com

Can you turn these things anticlockwise without upsetting the impeller, I've heard conflicting stories and also notice my OMC manual goes 'out of its way' to ensure you only turn it clockwise?

Anyway you're only marking a spot X degrees before & after top dead centre then measuring & marking the point between the first 2 marks to give you TDC.
Needless to say at 12 degrees before & after TDC you would measure the shortest distance between the marks not all the way around the other side, maybe that's what is confusing you.
Then align your 'new' TDC mark with the pointer.
Then align the pointer with the original TDC mark.
After that the pointer will be pointing at the original TDC mark on the flywheel..

Coment424, very first thing you need to do is like stated above, close the Seloc manual and buy a manufacture motor, year and Horse Power specific original factory shop manual and all that crap will make a lot more sense and save you time, money and possibly your engine too. If you can't find one on EBay, look for one as listed above in the comments. You went through all this machining and such, don't scrimp on the instruction manual now. Everything will be step by step in the proper shop manual with pictures, schematics, how to's and diagrams as well. You surely won't be sorry for that purchase!

Comet is mixing up his tasks here. He wants to know how to set the timing, but then goes off on the tangent of how to set the pointer for TDC.
That's his problem, a basic understnding of what he wants to do.

Comet....read and re-read, look at the motor linkage, study it vs. the manual.....don't do a thing til you understand.

By the way, Seloc manuals are the last resort, if you have nothing else to refer to.

 

[comet424]

ok what i want is first. i waiting for the machine shop to order all 4 pistons and bore it out so i can put the new crankshaft in assemble it
and engine never ran right when we got it

so then i wanna do the intial TDC but i figure ill do it without the heads on it as to bolt the engine down the 2 Heads are in the way so no point in bolting the head to the block till after the engine is bolted inthe motor leg.

but i wanna then make sure that the TDC mark is exactly at TDC so that the pointer is in the right spot... and then i wanna make sure the full throttle timing is in the full position.... but i just found a page that stuck together in the selco.. the 2 in circle didtn mean 2 degrees. says check the decal on the engine for the timing of the WOT... but of course i dont have this decal on the engine so i dont even know where to set it with the timing light

and i was reading the selco book in hopes it would start off with the TDC making sure the pointer is in the right spot... but talks about a 12 degrees and then well you seen above...

then i wasnt sure about TDC as like on my tractor and crhysler.. there is like 1/2" or so of play that can be TDC as when you move it doesnt instantly bring it down so thats why i had questions....

so now i dont know what the proper advance degree should be.. and i thought it be After top dead center when you set the degree but i see in the book only shows before top dead center.... but wont be for a couple weeks till i get the block back from the machine shop anyways ... so ill just re read stuff

 

[comet424]

ok so is that 12 degree mark that you mentioned how i got confused is the way the book says it you turn till it just touches the gauge so you be say the right of TDC and then tells your to turn all the way backwards thats how i get confused,,, but you dont need to know that when the degrees are on the flywheel right? and here is a link from that outboard site is that a good one? and got told marine engine site sells them too but i not sure if they the omc ones... also you wouldnt know any manual places in canada?? my marina only can get selco... and why is selco so bad several people said that?

 

[comet424]

and marine engine sells this book cheaper 60 dollars compared to 125 us bucks is it the same book? or are they different?

 

[comet424]

well damn it wont let me post the real link ugh
