It's the dot you marked in red that should be lined up with the mark on the crankcase. When the T1 is showing, the dots on both pulleys (the red) should be lined up with the marks on the crankcase (yellow). As Craig mentioned, the right pulley is attempting to open valves in this position, so it is under some spring pressure - you'll have to hold it in position (I jammed a screwdriver through one of the holes to hold it) while you slip the belt over it. When the belts are on correctly, you should be able to see the T1 mark, and both lines on both pulleys will line up with the lines on the crankcase at the same time. Again, with the spark plugs out, if you can turn the engine over two full revolutions without it stopping or jamming, then you will not be doing damage by running it this way (for short periods at least) - if it's off by a couple teeth it may run badly and make bad noises, but it is not doing physical damage (i.e. pistons hitting valves). That said, I would line the T1 mark up, line up the left pulley marks on the crankcase, then pull the belt off the right pulley, rotate the pulley until its mark lines up, then replace the belt.

A little tip when doing this. Rember to keep the tension side of the belt(the long side opposite the tensioner side) as tight as possible when aligning the teeth. As much as possible, keep all the slack on the dead side, where the tensioner will take it up. I used to hold the right cam pulley with a ratchet and socket on the pully bolt head,--Gives me good control over the pulley.

OK....big problem is that this confirms to my wife that I'm not as smart as I think I am! I'll be lining everything up here shortly. Question: If it runs rough after I get everything lined up, do I have a major problem or is it just a matter of making a few minor adjustments to the ignition timing maybe? I'll post a pic of the finished product before I take the step of cranking the bike up.

Be sure and turn the motor over several revolutions by hand with no spark plugs in and make sure ALL of your marks line up.If they all line up and no binding you should be good.

OK..as you can see in the image below, I have the right pulley lined up with the mark on the crankcase. Left pulley is lined up and I am at T1 on the timing mark. However, there is quite a bit a freeplay in the right pulley. I can turn it by hand clockwise and counterclockwise. I did not need a wrench to line it up with the mark on the crankcase. I'm guessing there is 2-3 inches I can turn it by hand clockwise and a little less than that turning it counterclockwise. By the way, when the marks are lined up, it is about 1/2 way in between the range of freeplay in that pulley.

Hey guys, is it me or does something look out of whack with that pulley? In the second picture Mark posted the line was out but the "up" looked like it was right where it was suppose to be. Is that an optical illusion? Mark, where is the "up" when you have the lines correctly lined up? You can't see it in the last pic you posted. I just did mine last week and that"up" was pointing straight up when the lines matched up.

As it sits right now....the "UP" is at the 1:00 position.

I think it was mentioned but I will remention it... When you are turning the engine over, use the crank bolt. Don't turn it from the cam shafts. By turning it with the crank bolt, it will simulate the correct action of driving the belts. If you turn it by the cam shaft, the marks might not line up correctly because of the belt slack. Don't turn this engine over with the starter until you are sure are right with the belts. Once you have it right by hand and you are sure of it, you can turn it with the starter with the plugs out to be 1000% all is good. Last edited on Wed May 13th, 2009 04:21 pm by ChasW |

When the T1 is showing and the left pulley is lined up, the right pulley should be under spring pressure in order to line its mark up. If you let it go, it should rotate itself (from the valve spring pressure) out of alignment. The "UP" should be facing directly up, not at 1:00. This is from the 1200 manual, and is how they should look:

I suspect the right side moved as the belts were replaced. The pressure of the valve springs make the pulley want to move off the mark. Don't know why, but the left side doesn't twist. I had to jam the pulley as I attached the right side belt, otherwise it twisted.

I just looked at your picture and I think I see the problem - you're lined up with the wrong thing on your right pulley. You need to line up with the dot on the pulley, not the slot. The "UP" should be directly up at 12:00.

I'm not sure what you mean by, "freeplay," but I'm thinking what's happening is you still have that adjuster backed off maybe. Pay particular attention to Hawker22's tip about keeping the long side of the belts taught so that all the slack is on the side with the adjuster. I'm not sure which belt is under which on your 1200. On my 1100 I had to put the left side on first. (Left as you're sitting on the bike, right as you look at it from the front.) After fitting the belt with the long side taught, I backed off the adjuster bolt to allow the tentioner to properly tention the belt, then re-tightened both adjuster bolts. Same on the right (as you sit on the bike) side. That one's a little trickier as I'm sure you know because that's the one that's trying to open valves when it's in the right position. I got the belt on, released the tentioner to tention the belt, tightened up the bolts on the tentioner, then followed Octane's reccomendation of turning the engine over 360º by hand and RE-tentioning the right side. (The cam timing marks will be off by 180º when you do this.) After all this, I again followewd Octane and many other's reccomendation of turning the engine over at least two full revolutions to make sure everything was right, re-checking the timing marks again afterward, which it was, buttoned it up and fired it up. I know this is a pretty wordy post, but I'm trying to paint pictures with words. I only hope it's been helpful. I look forward from hearing from you reguarding how you made out. We're all in this together!  Johnny Last edited on Wed May 13th, 2009 04:52 pm by JohnnyW ____________________ Had lots of 'em. Current rides: '82 GL500I and GL1100A.

Don't know why, but the left side doesn't twist. It's because at the T1 position, the right pulley has partially opened valves (it's connected to the camshaft), and the valve springs are trying to close those valves, so the springs are trying to rotate the pulley a bit so that the valves can close. I had to do the same thing - I jammed the pulley with a screwdriver to hold it in position.

I think the three reference point thould look like this: Timing mark through engine top window - T-1 lined up: Attachment: IMG_0274.JPG (Downloaded 249 times) Last edited on Wed May 13th, 2009 04:57 pm by mdbauer1962 ____________________ Life is too short - Live like today is your last day on earth!!!

mdbauer, keep in mind the 1200's pulleys look different than the 1100 pulleys you show in your pictures. On the 1200, the "UP" should be right at the very top when the pulley is properly aligned.

OK...the "UP" is @ 1200 and the dot is lined up with the mark on the crankcase and held in place by a wrench zip tied in place. (actually it's about 1/4 tooth off). I'll put the belt on, tighten up the tensioner and then turn the motor over by hand.

I just finished installing new timing belts on my '84 Aspy. When the timing mark T-1 aligned with the marks on the crankcase, the UP on both camshaft pulleys pointed straight up and the marks on the gears lined up with the marks on the crankcase/ The RH Belt was a bit of a test to get it on and everything lined up as is should be. I probably had that belt off a half dozen times before I found the right combination of manuvers to get it to line up within a half tooth. It was worth the extra effort and time. All is well, Life is again...Good.
