1982 1100 goldwing Timing belt replacememt woes

Postby hondarookie » Fri Jul 15, 2011 10:53 pm



Ok. I'm worried that I may have ruined my motor on my g-wing. I replaced both head gaskets but in the process somehow lost track of where my marks were at on the gears on both sides. So this is what I did. I pulled the heads off, lined up the T mark, and turned the gears on the heads until they both were close to where they lined up with the marks on the backplates and then bolted them on. Afterwards, I did need to turn each of them slightly to line up the marks on the gears with the marks on the vacillated. I then put both the belts on and cranked the motor by hand to Moe sure I wasn't hitting the valves. The.motor did turn without hitting. When I start it though it sure runs like crap. Like its missing on one side maybe? The right side backfires and there is NO power at all. It doesn't idle at all either. Did I destroy my motor? Can anyone help me please?

If you didn't bent a valve and/or hole a piston you should be Ok to start over..the issue maybe the crank shaft was moved so now it's not where it should be to line up the cam wheels on their marks. You maybe be 180 degrees out of synch. The t1 mark has two positions one that is correct TDC and one that is 180 off for setting the valves, belts timing etc. My guess is your 180 off. Your valves are opening in reverse time..but just my guess...note the crank turns twice as much and the cam wheels..one turn equal two on the. crank.

So should I loosen the belts and rotate the cam one complete turn then tighten the belts? And do I do that to both sides at the same one at a time or do that to just one of them?

take the belts off..rotate the crank shaft to T1, put the cam wheels on their marks and check the valves for loose-ness per the manual to ID TDC for #1 then belts back on and do final adjustment of cam marks..if needed. rotate by hand several times making sure nothing is hitting. Note you can only set the slack/cam tensioner in the 1/3 side after rotating the belts/cam wheels 180..you'll see as you rotate the belt changes it's slack on top and then you can tighten the tensioner the 2/4 can be set before you rotate. This is all assuming you were off 180 to start with..

To check you TDC you want the piston at it highest point and both valves closed on #1

here's another guys take on resetting belts

FIRST, the best thing to do is loosen up ALL the rocker adjusters completely.
This will help avoid bumping a valve because you'll need to rotate the crank to get it in time for the other belt.

Now, rotate the crank past 2 TDC slowly feeling for any resistance.
Since the pistons will now be down in the bores you can safely rotate the cam separately.
Turn the cam so the UP is up and timing mark is set for that cam.
Next rotate the crank to 1TDC and install the belt.

Hand crank to feel for resistance and double check both cams timing.
Adjust the valve and hand crank again feeling for resistance, again verify timing marks are good on both cams.

If you are 180 on one side....is that even possible? After pulling my engine for stator issues, I changed the timing belts also. I had it at T1, both cams "up". The left one was easy. The right one was a pain. I decided to rotate it 180 to relieve the spring battle. The belt slipped a bit. I felt the valve tap the piston, so I pulled the belt off the right, it popped back to a rest position. I then counted teeth and rotated the engine until both pulleys were lined up then put on the right belt without fighting the spring. Now at T1, both ups are either up together or down together. That's correct, isn't it? Anyway, it cranks slowly now, won't start, backfired a bit with starter fluid.

I don't think you messed anything up,,,but keep us posted..You know everything is correct if all the valves and their clearances are good...I would check them all before cranking it next time... :D

I think you are on the right track. I replaced my timing belts once and got the left one off a tooth or maybe 2. It ran but very weak. I can't remember what caused me to be off that far but I believe it was a funky marked timing sprocket on the right side. I remember it looked wrong and when I replaced the belt I put it on the money according to the marks but the timing was off terribly. No damage but ran horribly.
