Replacing timing belt/alternator

Hello,
I will be replacing both of my belts, timing and alternator..

I was just wondering if there is anything i should keep in mind/look out for when getting this done.. I am taking this to a mechanic by the way... Should i take this to a rx7 specialist or a mazda dealership?

Also should i replace anything else since alot of stuff will be removed ?

Umm... Rotaries don't have cams/valves etc. therefore no timing belt... If a shop is telling you they can change your timing belt I'd suggest going to a different shop. Allthough replacing the accessory belt and alternator should be a really straight farward and easy job for ANY shop. Allthough normally I'd reccomend a specialist for just about anything I think just about any shop just might be able to tackle this as IIRC they won't have to remove much of anything other than the alt itself to do it.

you should probably replace your turnlamp fluid while your timing belt is off

Sorry my mistake..
accessory belt and alternator is correct my terminology was off.
So what is the accesory belt? is that the one that connects to the air pump?

So if there is no timming belt, does this mean no timing is required?
so i could possible do this on my own?

There is no timing.

You can definitely do it by yourself.

Malloy Mazda and Ray Crowe for parts, their number is everywhere.

download the manual for a how to.

seriously, you can do this. it's simple. you should also check the idler pulley and see if you need a new one, they're only $50 and it'll get annoyingly squeaky if it's old enough.

NAPA has very high quality belts. Replacing the alternator/belts in a very simple job. Just be patient and DON'T GO TO A STEALERSHIP.

Top of Third Generation Specific. Sticky called Tech Manual Directory

Call Ray at Malloy Mazda. Use the search button and look up Malloy mazda. You will find the phone number.

Trust us about using Ray. Do not use other dealers. Example: I just bought a water pump from Ray, Dealer list was 111.80, Ray charges 65.00.

These are both accessory belts. One belt for the Alternator, Water Pump, and Air pump. The other is for the Power steering and A/C.

I've purchased after-market belts before. The PS and A/C belt was fine but the Alternator belt never fit properly. I replaced mine three times over two years. I finally bought the dealer belts. Perfect fit. The Alternator belt is expensive though.

Please understand there is NO Timing adjustment.

the cool part about a rotary is this:

take belt off, put new belt on. done. it doesn't matter if anything turns or moves, just make sure you get the belt on at the right tension.


So easy... a cavema... nevermind.

Your idle belt is located right next to the flux capacitor.

There are only two belts. One drives the alternator, waterpump and airpump; the other drives the power steering and A/C. Timing is done by a timing plate on the base of the main pulley which is read by two sensors.

Ok....call Ray at Malloy, download the FSM (factory service manual) from the link that Mahjik posted and do it yourself. Its not hard at all, and there is no need to adjust any sort of timing.

the part #'s on the belts are 5050530 (5PK1345) & 5060410 (6PK1040). the 5050530 is 53in long inside area. the 5060410 is 41in long. the 5pk and 6pk means number of groves in belt and the 1345 and 1040 means length in mm. just what i have found out.

the problem i have is the longer belt for the water, air pump and alternator for some reason is just a little short. only thing i can figure is the bracket that is the adjustment bracket that holds on the air pump is installed a little wrong and for that reason even with both lock nuts loose and adjustment all the way in it still wont fit. i am going to try a 5050540 (54 in long) and see if this works. ill let you all know
