I have the 249 belt - sure seems tight...Soooo...
What is the diameter of the tall block tensioner??
I did some shopping at the junk yard and found some promising steel units:
Mopar 3.5L V6 idler: 2.25"
Mopar 2.4L "head" idler: just a wee bit smaller than the 3.5 unit.
Mazda 4 cylinder idler: 2.00"
So I mounted the Mazda unit at the lower motor mount/PS bracket hole, used
a longer bolt - Perfect!!! :thumb:
Backspacing is exactly what is needed, and belt tension is just right on the front side of the belt.
There is no adjustment, but from what you peeps say the tall block unit is too tight to adjust any way...
I would like more "wrap" from the belt around the crank, as the belt goes straight up from the crank to the idler above, but this also gives a good angle from the exhaust sprocket to the idler around the PS bracket... :clap:
Pics to come....
