bgambino Posted October 14, 2003 Share Posted October 14, 2003 I love the screw adjusters for tightening the "fan" belts on the 95 Legacy I recently bought.....after 23 years driving subarus, it's a nice addition But, it seems one could easily overtighten them...anyoner have a feel for it?

mtsmiths Posted October 14, 2003 Share Posted October 14, 2003 I was taught that you should be able to deflect the fan belt 1/2" - 3/4" using one finger ... then it was right. 'Course back then Fuji Heavy Industries was still digging out from the rubble left by B-29s, so who knows now! Quote Link to comment Share on other sites More sharing options...
frag Posted October 14, 2003 Share Posted October 14, 2003 The previous advice is good (says who?...) But put more than a little pressure on the finger... Quote Link to comment Share on other sites More sharing options...
Strakes Posted October 15, 2003 Share Posted October 15, 2003 Apply 22 pounds of pressure to the following point: Midway between the alternator and crank pulley on the power-steering belt. New Belt deflection: .27-.35 inches Old/Used Belt Deflection: .35-.43 inches For the other belt--Apply 22 pounds of pressure to the following point: Midway between the Airconditioning and the crank pulley on the airconditioning belt. New Belt deflection: .29-.33 inches Old/Used Belt Deflection: .33-.39 inches Source: Alldata Automotive Repair Manual on CD-Rom How do you apply exactly 22 pounds? I don't know.

frag Posted October 15, 2003 Share Posted October 15, 2003 I asked myself the same question when I read those in the manual. Maybe put the car on its side and put a lead weight on the belt... Quote Link to comment Share on other sites More sharing options...
cookie Posted October 15, 2003 Share Posted October 15, 2003 very precise or we would all have dents on one side. Quote Link to comment Share on other sites More sharing options...
mtsmiths Posted October 15, 2003 Share Posted October 15, 2003 One finger, 1/2" - 3/4" deflection. Them ol' pepper tree mechanics wuz smart. Quote Link to comment Share on other sites More sharing options...
frag Posted October 15, 2003 Share Posted October 15, 2003 Them ol' pepper tree mechanics wuz smart I've heard of shade tree mechanics (and consider myself to be one) but never of «pepper tree» mechanics. From where does that expression originates? Quote Link to comment Share on other sites More sharing options...
mtsmiths Posted October 15, 2003 Share Posted October 15, 2003 Most of the available shade trees with a low horizontal branch strong enough for a pully were pepper trees. The best pepper tree machanics were always the old Mexicans. Quote Link to comment Share on other sites More sharing options...
cookie Posted October 15, 2003 Share Posted October 15, 2003 trained with they showed a tension scale that looked sort of like a scale you use to weigh fish. I never used one myself and never knew anyone who did. What I have seen with belts that is more of a problem is universal types that are just a bit thinner than stock that don't run correctly in the pulleys. Now of course we have serpentine blts that cause tensioner problems and cost more to rectify than some of my first cars. I just push down on the belt for deflection and if it squeaks I tighten a bit more. Quote Link to comment Share on other sites More sharing options...
