This may have already been answered. But What Belt could I use if I remove the air pump on my fd. I heard that there was a GM belt that would fit.
If anyone knows please let me in.
I have searched the boards and cannot find this info.
Thanks,
Ben

you need more than a belt, you need a larger waterpump pulley because your new belt path will barely touch it. several co.s seel them, I just put a greddy kit on mine. comes with an underdrive pulley for the waterpump, alternator and new belt

GtRx7

After I installed my midpipe, I got rid of my air pump. I used a belt labeled 295K4. From what I can remember the 295 was the size of the belt, and the 4 referred to the number of ribs on the belt. I've heard some people use a larger belt , which was labeled 300K4. The 295 is a little tight to get on, but once it's on, you can adjust it. The 300, slides on easier, but you need to increase your adjustment on the alternator bracket. The correct belt would be either a 295K5 or the 300K5. The reason being is that there are 5 ribs on the pulleys. Unfortunately, most of the stores I went to, only had the 4 rib belt. Someone on the forum from way way back posted a site that sells the 295K5 belt. "Do a search" on 295K4 or 300K4.
I've been running this belt for about 8-9 months.(always check your belts, and carry extras in the car). Temperature, and voltage seem consistent with the old air pump/belt setup.

Gt is correct. You can use a number of belts between 28.5 and 30.5 inches.




My question: how long a belt to go on the other side of the water pump pulley? I am using a 29 incher on the inside, but I want to now go on the other side.

I know people do this, how long is the belt?

How about running a piece of string around the pulleys till it meets and measure the length of string...ingenious!

The water pump is a centrifuge pump. It's designed to spin in one direction. Do not put the belt on the other side of the pulley.

Get the 300k4 belt. Chances are that you aren't going to find a 5-rib, and 30.0 inches the perfect length for installing and adjusting the belt.

Why do that, when someone else has already taken the time to find this info out? Then you can call advanced auto parts, give them a part number, and find out they have the exact belt you need (just like I did, moments ago).

Why don't you go chisel out a set of "Stones that roll" and call them "wheels"?

By the way, thanks to all of you who posted helpful information. This is going to all be on my "ultimate non sequential mod" diagram/writeup.

The main problem is people shouldn't "solely" depend on this forum for help, as it's just a forum. Just because it's here doesn't mean they'll get a response or a correct answer to their questions. Sometimes people need to at least try and help themselves and in this case 2 things would have gotten him a quicker answer than the 3 hours it took for someone to respond:

1. Searching... I'm pretty sure this isn't the first time someone wanted to remove the air pump

2. Finding a solution on his own by using a string to measure the distance

While this forum can be quite helpful, it shouldn't be depended on so heavily for every single answer.

K2RD carried a 5 rib belt that fits perfect with the Greddy pullies and no air pump.. they want $24 for it though.

That makes perfect sense Jonski, thanks.

But I have seen belts run like this.
I have also SEEN a stock RX7 with a 200 mph speedo, but that is a different mystery all together.

This months SuperStreet actually has the FD running the pulley the other way, but I have seen a handfull more.

You are right, however, for something like this, where there is just a measurement involved. I would rather ask and learn. Then compile my data, find out what the majority rules, and make my decision. I might have measured 30.5" for my belt, and purchased one that way, only to have to modify the adjustment of my alternator.
Or I can come on here, and talk to a few guys that have done something different (say a 29" belt in this case) and it will work out great with no modifications.

P.S. got my 29" 5 ribber from Advanced (Part #5050290) for 7 bucks, and fits perfect (a little tight, but it fit).

I have done plenty of searches on this topic. I just like the most up to date information as possible.

Do you read encyclopedias for current events?

Another thing, Why is there always someone like you that will spend your time telling everyone to "SEARCH" in a smart *** way, rather than using that time to help them with some knowledge you have aquired?

I bet you are one of those guys that won't pop your hood for fear of having someone "copy" the mods you have. Like no one else has seen a CAI and DP

Go home if you aren't going to help, no one likes a pie hole!

See you work backwards, you will take you car apart, and then try to figure something out.
Whereas I figure it out, and then take my car apart.
Don't you get it??? You are fighting a losing battle. Anyone in the right mind would tell you to "READ UP" on something before you attempt it. With your method, I would be removing parts, and creating downtime for my car.
I don't know if you own an FD, but I have to enjoy every second I get out of that car. Because lately they have been few and far between.

What in the heck are you talking about? You don't need to remove anything just to measure what size belt you "would" need if you bypassed the airpump.

You completely missed the point of my post. My point is, people need to at least may an attempt to figure things out for themselves. Why? What happens if these servers go down for a few days (and they have in the past). Are they just going to sit there and wait for the forums to come back up instead of trying to research their problem on their own? I hope not. You can't expect people to help you out all the time. Sometimes you need to man-up and get it done yourself.

Nope, I don't own one, I just hang out here for fun....

Up to date info? The car hasn't changed since '93, why would the belt size change?

That's like wondering if the stock '93 rim size has changed since '93.

What you don't understand is that I'm attempting people to "help themselves". Showing them how to use this forum in a way that can benefit them more than "just posting messages and waiting for days for responses". This forum has years of information just waiting for people to research and read. However, they'll never find it without searching and putting forth a little effort.

If I'm not going to help? You need to spend some more time around here.....

fc1jz

I was just trying to make a point. You wrote an entire paragraph on why to search and that I should take the time to do this myself. When you could have just said 29 inches.

Your right the car has not changed since 93, but people have had different experiences between 93 and now. I want to know these experiences.

That is how I make decisions on mods. Based on experiences that other people have had. Not going out and taking a measurement.

I may be new on this forum, but I am not new to this car. And since I know how often, and difficult work on this car can be, I decided to come on here and give people help. And in turn receive help.
Now I could go around telling people how stupid they are for not doing something themselves, or I can help them.

Lets just say, I feel sorry for those you have "helped"

Stupid? Who did I say was stupid for not searching?

I simply answered the question as to why people shouldn't depend on this forum for their ONLY source for working on their cars. It seems it's you that has developed the complex about misreading my post.
