Timing Belts

#1

Post by mmrabit »

Hello GoldWing owners, I just bought 78, what I fine machine.
I changed the timing belts.
Followed all the instructions and u tube videos I could find, all seems fine but as I rotate the motor the belts get loose at one point then tighten back up.
Is that normal??
Thanks in advance for any advice

when the crank to cam pulley side is tight, there can be a slight amount of slack on the other side. The idler is spring loaded, and sets the proper tension, when the other side is tight,

I appreciate the replies, I really think I have it right but trying to convince myself a little more.
I cant see how not to have some slack in the non tensioner side for a brief moment while the engine spins over and the cams load an un load from valve spring tension.
Also I understand when things heat up they also tighten up, the drive belt on Harleys I have had tightened up after riding for a while.

i had the same trouble with one of the belts, turning the crank 360, timing mark facing in, did the trick for me on the tension.

Also the cams put tension on the turning of the crank..so it could be that too.
