When tightening the B+ or primary wire to the alternator, the proper torque
would be approximately 25 in/lbs. (not foot pounds). Without a torque wrench,
if you are using a 6" long wrench, I would say it should feel like you are
exerting about 5 lbs of force (weight of a bag of flour) on the end of the
wrench while tightening.
One last word of caution, when you do this, resist the temptation to
over-tension the drive belt for the alternator. Too much tension and you will
destroy the bearings in the alternator in very short order.
Do you know how to properly tension the belt?
Thank you for your reply.
No, I asked around and was told 'no idea, mainly by the mechanics sense'
which doesn't sound very repeatable. Knowing German design, there must be
some way to do it properly. I just assumed about 1 inch deflection out in
the middle somewhere would be ok. There are THREE belts between that
alternator belt and the outside world! and the tension on one of them is
so strong you could bounce a quarter into the next county off it.
Belt tension is one of those universal things. 1 inch deflection in all the
belts would be desirable.
If things start squealing, you can make them tighter. I would take the
opportunity to inspect and possibly replace your belts. Buy the more expensive,
higher quality Goodyear brand belts if you can. There is a big difference
Also, use a plastic scrubbing pad to clean your pulley surfaces if possible.
Just be sure you get all the residue out of the pulley after cleaning.
When are you going to do this deed?
Sunday I spent two hours just removing the pulley to replace with, you
guessed it, one completely different! sigh.
Since alternator is shot, didn't even bother to replace the 'fan' section
[have a stack of left over parts], just bolted back together capturing the
belt which by now is very disdended [even small sections thinned by wear -
After that experience, and having all my auto tools in storage with NO
access, so won't buy more, don't feel real confident to take on the task.
Tested the pulley and belt combination with short drive. This is te first
time ever the belt stayed on for that long a time. AND didn't flip over!
kept its V-notch toward the inside! So armed with confidence I can drive
to the nearby garage that I've been talking with, will let the pro do it.
...I couldn't even find where/how to remove the other THREE belts to even
get at that bottom belt!
I guess I've verified the adage relating the ability to drive nails or be
an automechanic. I can drive a nail very well, three hits and its in, so I
guess I'm a rotten mechanic. As verified by the two hours JUST to replace
Are you at Rule in Boston? just to taunt you, it's 71 here.
Thanks again for the URL with pics. That gave me the confidence to go
replace the pulley to make it to the garage. Oddly, downtown Phoenix has a
myriad of 'mobile' mechanics, but rural has none. Seems backwards.
We set our thermostat at 82 ! with this cold wave, we're freezing, the
house got down below 80. And don't even run the cooler til the house gets
above 92. think about delta temp, with outside usually less than 20-30
degrees different than inside, we're prety energy efficient. Now compare
to your area, probably 10 versus 68? that's a difference of 50+ degrees
!!! correlary here would be either 20F outside [very rare, if ever] or
140+ outside [hope that NEVER happens!]
But on the plus side, you won't get burnt by your car when you touch it.
...only the occasional tongue frozen to a flagpole.
ARRRGGG!!! a bit jealous! beautiful area
We used to go to Europe about twice a year and to relax from those
'vacations' we used to go down to the Del Coronado and stay a week in
'our' room. - little known room in the old section on the fifth floor with
NO rooms beside or over you, overlooking the ocean. With the sash windows
open you can hear the ocean, smell the breeze. There's an old fashioned
popcorn machine at the nearby liquor store the type that pours it out as
it pops. We'd sit in the room in bathrobes with our feet on the window
ledge, drink champagne, eat popcorn, look/listen to the view, and just
yep, a bit jealous.
