1975 to 1987 4-cylinder cog Honda timing belts are a really common automotive type that ought to and can last safely to 45,000 miles, provided they’re utilized in a car with close ratio automatic shifting and fairly medium to high freeway to highway use. BUT, put them during a early Honda Gold Wing motorcycle (GL1000, GL1100 or GL1200) with its manual shift and wider gear change steps creates another situation. Bang, clunk, up and down, over and over – lashing and stressing the belts harshly, fixing stress and shear points round the belt.
You can’t tell a thing by watching them as they NEVER show wear, stretch or cracking. The belt construction, a bias fiberglass rubber laminate, doesn’t leave it because valve timing must not ever alter.
Hundreds of discussions with customers who have broken belts puts the danger range at 22,000 to 28,000 miles or 5 years, no matter mileage.Push them further is like playing Russian roulette together with your engine valves and your safety. Preventive maintenance is that the key. If you do not know when the belts were last changed, you’re in danger .
On the opposite hand, the 1988 to 2000 6-cylinder curvilinear cog Honda timing belts used on the GL1500 aren’t so risky and infrequently break but those darn radiussed cogs just start to wear during timing fluctuates. tons of times the bike just stops running thanks to sensor shut-downs when the valve timing span becomes too distorted or irregular. It’s no fun sitting on the highway once you can’t find out what’s NOT happening while all systems appear to start out and run.
