Belts? 300 cdi L6 4.9

kristopherdb
I have an 85 300 L6, I am not a motor-head or mechanic but I have this beast to learn on. There are two belts missing and I need to pass emissions.

1 belt goes from the air pump (Thermactor Pump??) to the alternator and another from the A/C to the water pump and crank.

I cannot find the belt numbers or what to get for the life of me.  Also when hooking these back up after 20 years should I do anything first, such as oil the condenser?

Kristopher - Welcome to the Bullnose Forum.  Frequently I have the documentation needed somewhere in the rest of the website.  And when I don't I usually put it on a page quickly.  But, in this case I don't have it on the site nor have the time to do it completely at the moment so will post it here to get you some info, and then put up a page later.

Here's what Ford's master parts catalog shows for a 1985 w/a 300 six.  Pick out your belt and you should be able to find it by Googling the number like JB-430-LB.  But, you can usually find the info by going to the website of one of the parts houses, like O'Reilly's, and entering your truck's info.

I will start with the air pump. I think the pump is seized up and will not turn, at least that is what happened to me when I removed the air pump belt for a long period of time. I was able to take it apart and get it to free up and turn by hand again. The air pump was rusted bad inside.

No problem.  And, just 'cause you asked and I didn't have it, there's a web page out there for Drive Belts.  (You can also get to it by hovering over Engines to the left and clicking on Drive Belts.  That's the beauty of a forum integrated with a website for documentation.  )

Quantity is certainly supposed to tell you how many you need. However, if you look at the illustrations I have of a 300 six (go to Engines/300 Six in the navigation menu) you'll see that they show only one belt to the alternator. But, those are "typical" illustrations, meaning yours may be different.

So, how many positions for belts does your alternator' pulley have?  If two, are they exactly the same width - there was frequently a smaller one running the air pump on some engines.

As for the r/b, that means "replaced by". So originally Ford used one part number, but later came out with another and noted that in the catalog.

Let me see what I can find on belt routing in the catalog.....

I probably have the 1986 routing. From looking at your photo, you should have, on the crank and water pump, from back to front; alternator, water pump and crank; power steering pump, water pump and crank; A/C compressor, water pump and crank; then you have an alternator to thermactor pump which if it was like the 460s is a 1/4" wide belt.

Hope this helps some, the problem I run into at most parts stores, the kid on the computer is younger than your truck and if the computer doesn't show it they have no idea how to look in a print catalog even if they have one.

Thank you. I literally called the local ford dealership parts department in Portland yesterday. The kid on the phone was like I don’t know how to look these up it’s so old. I was like 85 is old? Crap

I'm sure glad Bill responded as the master parts catalog has nothing on belt routing.  But, it it is still an issue my 1985 owner's manual probably does have it.

I would use the Canada belt listed for the alternator since yours only has one belt groove usable, then go from there on the rest. If you go to some of the parts store websites and plug in the sales number (not the Ford PN) you may be able to cross reference them that way.

The routing is different between AC and non AC. Looks like yours has AC, so according to this thread on FTE it should be routed as shown:

Thank you Gary,

Back when I had a 1980 straight six transplanted into my '66 F100, I went through a bunch of trouble to find a replacement alternator with a double belt pulley... then I went through a bunch of trouble trying to find two equal length belts so I could fill both V's (even two new belts off the same shelf at the parts house wouldn't tension right). So now I know what that extra notch was for 🙄. I was young and took things a bit literally at the time!
