Can't seem to turn crank for timing belt change.

Post by Mikeybob007 » Wed May 30, 2018 6:30 pm



I was given a "basket case" 1980 GL1100 that I'm fixing up, as a novice. The crank does not want to turn so I can see the timing marks. I have put a pretty firm pull on the stator bolt (as per video) without success. The spark plugs are out and I had to work to get the rear wheel to turn in first gear to move anything. I marked and took off each old timing belt and made sure the 2 sides of the engine were not frozen, then returned each to the mark and put on the new belts. I don't know what to try next to get the timing marks to appear in the observation hole in the crank. Do you turn it clockwise facing front, as in pull up on the ratchet? Thanks in advance. M

Well, it looks like the engine is seized. Remove the valve covers and back the adjusters all the way off. Remove the spark plugs and put a generous amount of penetrating oil in the cylinders and let it set overnight.Try turning it from the crankshaft bolt in the front, clockwise. You should have done this before removing the old belts.

You're turning it the correct way (at the back of the bike, looking towards the front, it turns clockwise). It sounds like the engine might be seized? Try pouring some ATF into the cylinders (or a mixture of ATF and kerosene) and let it sit for a day or two, to see if it loosens up. If it doesn't keep trying - move it back and forth a bit, pour some more in, let it sit another day, with luck, it will work its way loose.

ATF is in, let the soaking begin. Thanks for the feedback. I'll post how it goes and probably seek more help. M

This is my first Goldwing engine work, I put timing mark on T1 and both pulleys had UP in the top position. I installed some new Napa belts which turned out to be 0ne tooth too long. I thought they looked loose when installed but turned over engine with wrench on crankshaft bolt. about half way through the belts slipped and the cams spun a little. I got the correct belts and gently turned crank backwards to T1, i had to rock the cam pulley on rh side as it felt like piston was hitting a valve. I have both belts on with the UP mark on cam pulleys at top and crank on T1, I turned engine slowly through two revolutions and nothing hit. Does it sound like it is back in correct order?

Did you line up the marks on the cam pulleys with the marks on the inner cover?

Ok, I looked this morning and it looks like I have them one cog out. When T is lined up on crank, the marks on cam pulleys are about 1/4 inch out. I will relossen them and move the one cog.
