broken Trigger???

[ryanc]

While removing flywheel I wonder if hammer tap might have broken trigger? Is the trigger of one piece or does it have a break in the middle?? Hard for me to tell, the break seems very even and smoothe? can it be glued?? thanks for your help. rc

Re: broken Trigger???

Removing a flywheel with a hammer instead of the puller is asking for a lot more than a broken trigger. I've heard of crankshafts shattering from the shock wave. <br /><br />Best thing if you don't wanna buy a puller, is to run the powerhead down to your FLMD and slip a guy a $10 to pull it real quick.<br /><br />-W

Re: broken Trigger???

I've seen new triggers that have a split or seam across them.I also don't think using a hammer on the flywheel or flywheel nut would damage a trigger.But please get the corrct puller.If you damage the threads on the crank.......<br /><br />Why were you pulling the flywheel to begin with?<br />DHP

Re: broken Trigger???

Hello, It was this forum who told me to use a hammer on the puller nut. I did not beat the daylights out of the flywheel just as I was directed to. And as for slipping someone a 10.00 bill to remove flywheel they asked for 35.00 for two minutes work. <br /><br /> the trigger has smoothe edges at 12 o clock to the wires on trigger, the split looks like it was made that way, is that possible??? thnaks for replies and comments

Does it appear that it will function as intended with that split? Can you look it up in an online parts guide and get a peek that way?<br /><br />-W

Re: broken Trigger???

hello<br /> what kind and horsepower motor are we chatting about? ya must have gone in the front door cause most techs are like me and accept cash rather readily. mercs are usually the easist flywheels to pull especially if they have the threaded flywheel<br /> good luck and keep posting

Re: broken Trigger???

Below was my exact post to this fellow. If anyone cares to translate that into saying that I was telling him to beat the Sh*t out of his motor, or can find anything in it that says beat on the flywheel, then feel free:<br /><br />"Try soaking the crank/flywheel interface for a few days with Liquid Wrench or other suitable penetrant; then carefully apply heat with a propane torch to the center of the flywheel. Using an impact it should jar that flywheel loose.<br /><br />As a last resort, grab hold of the puller screw; pull upwards with a lot of force and smack the end of the puller smartly with a 2-1/2-to-5 lb. ball-peen hammer. Be sure you have something on the end of the puller screw to protect it from damage. It's also a good idea to run the flywheel nut down a few threads so that when the flywheel does pop off, it won't go flying across the room or into your head or other body parts!<br /><br />You must pull upwards on the puller when you smack it with the hammer, otherwise you put undue stress on the bearings."

Re: broken Trigger???

dude<br /> from Poulsbo? my sister lives in poulsbo she wants me to move there as well. any marinas need a hand out that way?<br />anyway theres a many of 200,225 jonny rudes that have to have a tap to make them pop. had one years ago that I did not leave the flywheel nut on popped and came up about 6 inches and took a bit of hide from my arm. I agree that sometimes you have to pull down tight on the puller bolt then strike a single sharp blow on the flywheel puller bolt center sometimes.<br />even some of the mercs that have the special puller need a small tap to pop them or you just keep pulling at the bolt.<br /> good luck and keep posting

Re: broken Trigger???

Hello guys, I am just a dad trying to help out his son ryan with his first motor. No one beat the flywheel just a tap on the center of the nut as the fellow had said to do and as well it flew off near hit me and also came the trigger.<br /><br />Neither my son nor I are trying to destroy anything but rather our first attempt at tearing down a motor. The ball bearings on the crankshaft were broken and two bearings were missing out of the race.<br /><br />somehow things have gotten out of focus and my focus is not on beating the flywheel to death but rather does or doesn't the trigger come with a break in the upper middle of it, opposite sides of the wires? The book I have (cylmer) shows nothing, not even a breakdown of crankshaft parts for the 1973 merc 200 20 hp, but it does for a couple of others which is of no help. Anyway I have looked on internet and still can't find a decent picture or drawing of this particular trigger.<br /><br /> Also, I found part of my problem in pulling flywheel was that I was useing a tree footed gear puller and should of used a harmonic balancer puller useing the two removed 7/16 screw holes on the hub. But as a newbie i am learnig the hardway.<br /><br />My problem concernig flywheel is that it came off in three pieces, hub, large starter rim then the centerpiece that engages shaft. my question I marked the hub and outer rim to match so as to reassemble but I did not know that the hub screwed into the centerpiece that stayed on shaft. will I be able to get this postioned correctly so that magnets will be in proper position?? thanks for your patience and expertise. I hope that this will prove to be a positive experince for my sons learning. thanks again

Re: broken Trigger???

Plenty of marina's around the Puget Sound area. You might have to go to some of the outlying areas, or closer to Seattle or Tacoma to find a marina big enough to support a livelihood. Winters might be a bit slow, you'd be busy in the summer though.<br /><br />Poulsbo is a nice little town with a good tourist base, having Liberty Bay and all. There is a marina with a fair amount of mooring but you'd have to check it out to find out how much business they have. Nice traffic jams with all the commuters to the Kinston-Edmonds and Seattle ferries. <br /><br />Usually it's not too cold in the winter, or too hot in the summer. Too bad summer isn't much longer up here, but then you wouldn't have the nice, green foliage. As long as you don't rust from the rain, or shake apart from the occasional quake, you should like it fine! <br /><br />Re: the flywheel & trigger; I doubt the trigger would have busted just from the shock of pulling the flywheel off. If I recall the split is supposed to be there.<br /> <br />If the 'break' is clean and straight, odds are that's the way it came from the factory. If it's truly broken, you'll see jagged edges.<br /><br />For the flywheel alignment, first try and see if there is a stationary timing mark on the motor. Hopefully you can find a good pic in your manual. There should be some kind of timing mark on the flywheel (such as a white dot or punch marks) and typically this'll align with the stationary mark when the top (#1)piston is at TDC.<br /><br />My Seloc book shows this year as having its timing adjusted with a dial indicator, rather than timing lite so you may be s-o-l in that respect. Maybe someone can post a pic of a 20HP flywheel, showing the relationship of the center hub's keyway to the body of the flywheel itself.<br /><br />I apologize for the prior rant, but I want to make it clear that I don't advocate destroying things; sometimes you have no other choice than to give it a bit more mechanical 'persuasion'. I've had flywheels 'welded' to the crank so bad that the only way you could get the flywheel off was to cut it off.<br /><br />Obviously you want to start with the correct tools and methods and the other techniques are reserved for the worst-case situations where almost nothing else short of a small thermonuclear device works (well, in the case of Suzuki head bolts on a saltwater-run motor you may as well nuke it! lol)<br /><br />HTH......ed

Re: broken Trigger???

hello<br /> I am not sure on the old 20 but some of the other triggers had a split line on the nylon ring. I have 2 of those old motors maybe 3 I think the tird one ran and just sat about and locked up another ran but leraked water from the water cover. I think the last ran but had a badly destroyed lower. what you describe is the flex plate arrangement. it is repairable. the hub(part that is splined/keyed to the crank) the plate (flexplate) is the flat disc part. the ring is the outer hub that contains the magnents and is called a rotor in some manuals. thats a hard way to learn sometimes. most manuals refer you to the proper tool to use some give an acceptable subsitute but we all learn that way sometimes. I have most of the scars left to prove it. if your interested in an old parts motor maybe we can chat. how far are you from kitty hawk><br /> good luck and keep posting

This in light of the fact that there was a suspected broken trigger. My mind connected the dots and assumed the worst. <br /><br />Worse comes to worse you'll need to talk to someone with an intact flywheel who can describe the relationships of the three parts in detial. <br /><br />If you can't find that here, try on John's Old Mercury board. A lot of peeps there have the little ones. Actually, Chinewalker (who also frequents here) prolly knows this by heart, or has a flywheel handy to look at. I just paged him for ya, he's a cool guy.<br /><br />-W

Re: broken Trigger???

Thanks ed mc, rodbolt and clams for your replies and comments. There is a mark on the flywheel but not on the power head and as you said you can't use a timng light on this one. worse comes to worse I can just rotate the upper flywheel one screw at a time till it fires up again. <br /><br />Having trouble finding gaskets for power head, I noticed when we broke it down there was no gasket where the crankshaft houseing comes together ?, matter of fact the only gaskets were the manifold exhaust and the cover for the plug holes and one for the carb. Isn't that stange?. In the event I can not find proper gaskets, can I cut them out of gasket material as was done in the old days?? or is there now an easier and quicker way to do it??<br /><br /> Rodbolt, I am in charleston s.c., not sure how far that is from you but I can check it out at mapquest.com .My email is remnant333@hotmail.com so as we can maybe discuss the motors you have. <br /><br /> Clams, thanks- that would be great if the fellow you spoke of shows up on the forum or you can relay my email address to him perhaps he can answer the timng thing more easily. thanks again<br /> thanks again for your patience and expertise.

Re: broken Trigger???

Hi Ryan,<br /> There are no gaskets at the crankcase face - just use a good anaerobic sealant (think mine s LocTite 718). There's also no gasket between the upper end cap and the crankcase - although there are usually some brass shims.<br /> I will take a look-see today and check if I've got one of those flywheels. Is it the one with the magnets on the hub and outer rim, or just on the outer rim?<br /> I am fairly certain the trigger is supposed to have a gap on the opposite side of the wires - it's supposed to be somewhat spring loaded to add tension to the guide it rides in...<br />- Scott

Re: broken Trigger???

Chinewalker I do need (i think) a gasket to go on my exhast manifold plate and there was some type of gasket where my spark plugs are. The only gasket i need is the gasket where the powerhead meets the midsection. <br /> Thanks all ryanc

Re: broken Trigger???

The exhaust plates use gaskets. And the water jacket cover (spark plug end) uses a gasket.<br /><br />And yes there is a powerhead base gasket.<br /><br />All these are avialble at your FLMD, just have your serial number when you walk in.<br /><br />-W

Re: broken Trigger???

Thanks chinewalker, clams,<br /><br /> The flywheel actually has four parts, top part(like a crown_ that has 8 7/16 srews that go thru the hub (underneath into the center piece that slips on shft key, the hub has screws also that I guess hold the outer rim (starter teeth) The magnets are located under the hub nearer the center and there is a slash mark line on the outer rim as well as a punch type hole on the outer edge of rim(hole doesn't go completely thru- looking more like someone took a drill then stopped half way. Hope this brings some clarity to flywheel. thanks alot for your time, effort and expertise.<br /><br />Thanks clams for pageing chinewalker and for info on the gaskets. There is only one metal shim (brass) located at upper ball bearing, there was no shim in the crankcase for lower shaft ball bearing. By the way, I took out the reed that rides on shaft journal asnd cleaned it up and checked measurements, but was surprised it didn't have any bearings- just rides the shaft- didn't see any wear or other obvious markings. thought that was wierd. anyway, thanks again.

Re: broken Trigger???

chinewalker--ordered the parts for my local mercury dealer. Gaskets--bearing--brass shim--end cap--ect--. Now they told me that it would be a good idea to replace my piston rod bolts. A tech there said that with the year of the motor, they probably are worn. They said they can't order them. So where do i go for the piston rings and the rod bolts? Thanks in advance Ryan C.

Re: broken Trigger???

If they are the kind of rod bolts that have a nut on the bottom side, they rarely are bad. Use a little locktite red on them and torque them 2-3 pounds under the book value to avoid harming them.<br /><br />The rings can't be ordered?? What's the serial number and HP again??<br /><br />You're gonna have to wait on Scott for the flywheel info though. <br /><br />-W
