How does cam chain tensioner work?
The tensioner ensures the correct and necessary tension of the timing chain that surrounds the crankshaft sprocket and the camshaft sprocket. It exerts full control, making the chain run smoothly, preventing it from rattling and coming off the sprockets.
What happens when the tensioner goes bad?
Many of the engine’s accessories, such as the alternator, water pump, and AC compressor, can be belt driven. A seized or loose drive belt tensioner can cause the belt to snap, which will disables those accessories and can cause problems such as overheating, a dead electrical system and battery, or a disabled AC system.
How long do cam chain tensioners last?
I don’t object to spending the extra money on any of the cam design upgrade options (hydraulic, gear drive, etc), but the truth is, you can leave the existing design in place, replace the tensioners with new ones and expect to get another 40K-50K miles out of them. For most people that’s 5-10 years of service.
How tight should your cam chain be?
For me on as fresh chain it should have no slack but very slight tension. If you lightly tap it it should not flutter but not be rigid. It’s hard really to describe, it’s more of a feel thing. It will stretch a bit once it runs so you don’t really want to start out with it loose.
When should I change my motorcycle cam chain?
There is no reason to change a cam chain unless it is worn out and they wear out very, very rarely. They break even more rarely. Few people put those kinds of miles on their motorcycles.
What happens if timing chain tensioner breaks?
No matter which type of engine you have, a broken timing chain will cause your engine to immediately stop running and turn off. However, if the timing chain breaks, the piston and valve will collide. The result will be a damaged cylinder head, valve, piston, cylinder, and/or camshaft.
