I'm trying to solve problem with a Mitsubishi v-belt tension without using a service manual. I've been told that it should be possible to deflect the belt about 1/4" in the center of its run with finger pressure. But I will try one other trick since they break too often. A service manual for a 1986-1989 Honda Accord says to apply 22 pounds of pressure then:
The 5" span alternator/water pump wide belt should deflect 4-
6 mm new, 6-9 mm old. The 9" span narrow AC belt should deflect 10-12 mm. The 12" span narrow power steering belt should deflect 14-17 mm.If:
5" = 5 mm, wide belt 9" = 11 mm, narrow belt 12" = 15 mm, narrow beltThen:
7 " = what mm, narrow belt?The narrow belt spans 7" on my Mitsubishi's alternator/ water pump compared to my Honda.
Thanks
