loosen ALT. bolts
remove stock fan with 10MM wrench (can be hard at times)
if i remember correctly the the belts (power steering and A/C) may be in the way
loosen the nuts for these on the pulleys and remove them also.

RoTa7

remove fan shroud

remove the ac, ps, and air pump belts (by loosing the the adjuster bolt so u can just slide them off

loosen the alt adjuster bolt, slip off the alt belt over the fan (about 2-3 blades at a time)

put everthing back in reverse

Loosen both alternator mounting nuts. One of the nuts is attached to an adjustment bar, the other is affixed to a mounting point bolt. Rotate the alternator down to the lowest point, slip the belt over the alternator pulley and the "crank" pulley. Using a lever, rotate the alternator up to a point where the belt is snug with a little play at midpoint between the pulleys. Then as you hold the alternator at that point with the lever, tighten the adjustment nut and then the other nut. Recheck the tightness of the belt--not too tight, not to loose.

Both the FSM and Haynes manusl have instructions, and should've been read before posting.

Totally unnecessary.

lost my haynes, not removing the shroud.

soulja77

just finished doing it!

Ok, for future reference:

Replacing Alternator belt for the fc

- You do not need to remove the fan nor fan shroud. Belt will slip right over the fan.
- loosen the adjustable pulleys, and loosen the other belts.
- loosen the alternator. Make a mark on the bracket so you know where to adjust it to later.
- slip the belt over the fan and onto the alternator pulleys
- adjust alternator accordingly, and work your way backwords

you will need a 24mm, 16, 14, 12, 10mm sockets.

Labor: took me 1hr more or less.

Cheers.

Forget the lever use one of these!

You don't need to do that, and probably shouldn't since the new belt won't be stretched like the old one. You just tighten the belt to the factory specs.

Wondering Where the 24 mm and the 16mm Come into play when Replacing the alternator Belt.I can see the 14,the 12 and the 10mm,they are all common sizes.I have never Used a 16mm on my Engine,so I am wondering Where you Used it.

soulja77

it's tricky if you have never done it before... and i am sure there are many rx7 owners who wondered if there was or wasnt a shortcut to doing it...

the bolt:
24mm, not sure what its called, but its another adjustable pulley... possibly the power steering?


10's for the strut bar

There is no 24mm bolt or nut anywhere. I've adjusted/removed the alternator many times and I don't even own anything that big.

RoTa7

i removed my fan shroud for easier access for everything also easier to get the to air pump bolt to loosen it. wow 4 10mm bolts max ( i had 2 10mm) on a fan shroud lots of work.

soulja77

i used the 24mm on the pulley close to the battery... the one thats adjustable.

You people make it sounds so complicated. I can change my belt in literaly 2 or 3 minutes from removing the old one to having the new one on and running again. Loosen the 12mm bolt on the adjustment "thing" for lack of better word at the moment. Loosen the larger 14mm bolt on the pivot. Take the belt off the pulley. Slide it around the fan, blade by blade till its off. Reverse for reinstallation...

There are no 24mm bolts or nuts anywhere on the alternator. Near the battery? You sure you werent messing with the a/c pump or something? Even then I dont know if there is a 24mm bolt or nut.

You have not lived until you've done this at the side of the road, stuck on Yonge St. in downtown Toronto, on a Sunday afternoon, in a rainstorm, with nothing but a set of Vice Grips....

Long story short there is no real need to remove the fan. Simply loosen all other belts to the point where you can slide the alternator belt under them, and then wiggle the belt over the fan, alternately moving it from side to side until it clears one of the blades. Then slip it off the remaining blade. No need to remove the fan or anything else.

This won't apply to installing the new belt, but if you are going to get rid of the old, worn and stretch belt, just cut the damn thing! Nice and quick!

What pulley needs a 24mm socket to adjust? My pulleys (power steering and A/C) have a long bolt that goes through them that I just turn to adjust. Makes them go up and down. Those bolts are 10 mm or something thereabouts.

So was the stock system not to your liking or is this some sort of necessary mod to the engine that I would have no clue about?

TRRAPLN

Correct, the stock system was not to my liking. I no longer need to use a pry bar, marr the engine paint, risk breaking the alternator, slip and bust nuckles and I get a positive adjustment with ease.

It is simply an innovation in the "hot rodding" spirit. Perhaps you could make one too.

Can you share how you made it?

Well in that case good job I guess.

I just use my 1/2" socket wrench and jam it under there and lift up.

If you can't look at the picture and see exactly how it was made then you probably can't make one.
The only thing not immediately obvious (but completely intuitive and common for this type of adjuster) is that the center hex is tapped with RH threads on one end and LH on the other. This makes it possible for the total length to expand/contract as the center is rotated.
