348 cambelt mass

I'm calibrating my sonic tension meter to check my newly-installed belts. Does anybody know the mass measurements (g/m) for 348 belts? Thanks in advance.

Thanks - I thought someone had done this before and might share the numbers.

 

Okay - I measured it to be 145.4 g/m

 

Dave - If you could send me your frequency readings that would actually be extremely helpful. I'm using a Gates 505C frequency meter.



Ernie - yup, I know...I'm out of control... but I want to make sure. You're exactly right about the spring setting the tension automatically. I want to measure the tension on the set cambelt knowing what it "should" be and see if my measurements match the accepted tension value. I'm trying to make sure my measurement technique is correct so I know the alternator and A/C belts are done correctly too as they are not automatically set.

Thanks,
Shan

 

Peppi - thanks very much for posting the belt tension values. What I was actually looking for was the belt material density number to plug into my tensiometer (sonic frequency meter as opposed to Staeger deflection gauge) to verify the tension and my measuring technique.

I wish you success with your Mondial Cab. Take your time and have fun with it. Best wishes,

Shan

 

I thought I'd post this for my comrades (current and future) who choose to use the sonic method:

The correct mass number for the cam belt (using Gates 505C tables) should be around 4.5g/m, not 145 as I previously stated. I think what the number refers to is just the density of the belt backing without the teeth, so it is probably not as simple as weighing the entire belt and dividing by its length. I plugged this number into the meter and measured the new belt tension and got 158 Nm - exactly within specs. Now I know how to measure my accessory belts with confidence as they are not automatically set as the cambelt is.

 

Thanks Lawrence - I'll keep that in mind although there's nothing wrong with finding out what has already been done.
