Timing belt replacement

Post by RodL »



I have read alot of the articles here on the replacement and it dowesn't sound like a hard task. My question is whether you can do it with the engine still on the bike? I talked to the local shop here and the mechanic said that it has been a real long time since he has done one, and wanted ~ 4 hours labor minimum. He was saying that you have to remove the crash bar to do it. I know the radiator will have to come off, but does the crash bar also have to come off?

My bother is an auto mechanic and between him and me being the gopher/beer fetcher, I think we can do it!

The engine stays in the bike. It's a good idea to remove the radiator, to save your knuckles. I never did a '83. Crash Bars are different on each specific model. Just take a look under there.... does the crash bar interfere with removal of the front belt covers... maybe they do on an '83 ??

Crash bars do not need to be removed but they do need to be loose so you can get the cover out.
Engine does not need to be removed. Put the date and mileage on the inside of the cover so one knows when the belts were changed.

Go to the "How To Articles" section of this site. There is a few articles there on belt replacement. They are great. I just did mine last summer, and I can tell you THIS.....although it states that you have to keep the timing pulleys from moving.......you WILL have to turn one of them anywhere from 1/8-1/4 of an inch (approx. 1 tooth worth) to get that belt ON. All the timing marks will still line up, but if you don't let one side move "JUST A PINCH"......a brand new belt won't want to go over the pulley, and you will use words in the "mechanics vocabulary" incessantly..!! Just make ABSOLUTELY SURE that the marks line up before you tighten everything up again. That's me $0.02..!! And after you're done.......say 2 Hail Mary's and 2 Our Father's......(cuz of the cussin')
It's not WHAT you ride......it's THAT you ride.

For the right side belt, since the cam wants to turn about two cogs CCW from the timing mark, I simply turn the crank a corresponding two cogs CCW, that way you don't have to fight the valve spring while getting that belt on. After the belt is on, you can turn the crank back to TDC and confirm the timing mark on the cam gear lines up correctly.

That is an excellent suggestion!!!

I have changed the belts on 3 Wings, and it isn't a hard task. I always just stayed focused and followed the How To articles. If it takes a bit longer than expected, that's how it goes sometimes. Better to take the time to get it right. Even off just one tooth can cause problems you don't want. :o

I would also save the beer run until after a job well done. :)

Yep, my brother and I follow the same rule on the beer run!!

All the information is very good and I thank you all. I will sit down with him and let him go through the how to's to get a feel for everything.

Exactly why I do it that way! Easy to be off a cog fighting the spring (ask me how I know). Bike will run "OK" with the right belt one cog off, but it doesn't run "right". :lol:
