What type of oil

mhfd112 on Tue April 03, 2007 8:19 PM User is offline

Year: 98
Make: International

I will be recharging this truck at work soon. I was planning on adding a little oil to it. A tag on the compressor said to use Lubrizol ester 2916. If I can't get that will ester 100 work?

The BVA Auto 100 uses Lubrizol as its base oil.

Hey Hog,
The Old International uses a CCI (Box/lawnmower engine) compressor that have a felt doughnut in front of the shaft seal to absorb some of the slinging oil. To answer your question, I've been using Ester 100 to mix with the CCI Lubrizol. Leaks need to be fixed before recharging.
CCI's reason for nearly being out of business is that:
1) The belt load applied directly to the shaft bearing and the high compressor and diesel engine vibration increases the clearance in the front shaft bearing
2) The old style mechanical 2 piece shaft face seal leaks when the worn front bearing lets the shaft move off center
3) Oil and refrigerant leaks profusely
4) Recharges become a waste of time without fixing/replacing the root cause of excessive bearing clearance. Even a new shaft seal is ineffective.

For the International 4000 series trucks (engines Detroit 466 and 466E) I worked on a knock-off replacement kit using a cast steel machined adapter bracket and Sanden compressor that keeps the same OEM hose fitting locations. No changes to the hoses are required. Sanden's # is 4467-9740 from AMA via Big O.
Andy and Gary from Big O visit AMA. Guess Paul predates us all in this A/C business (1955). I'd like to hear all the old A/C history from AMA for my history book.
When I installed the first hand made prototype CCI replacement, the discharge hose was old and brittle and had frozen to the CCI, therefore I had to rebuild the hose assembly using the old fittings and new collars and barrier hose material. International is too proud of their new hoses. If you follow suit, be sure to mark the relative respective orientation angle of each end fitting before recrimping. International also distributes 8,000/year of the knock-off kits with good success.
Cordially,
ICE

Don't think I have meet Gary yet, he is in thier truckj divison correct? Andy and I are friends and I take money from him every time the Suns play Dallas. HEHE Andy and Tommy have been out here a couple times. Would like to get back to Texas to visit our friends and even come by Sanden if the offer is still available. Just not sure when I going to be able to make it out there.

Tim,
Gary is one of the tech/international/ old timers from Frigiking days. We'd like to see you out here, but summertime is not good for a Texas vacation.

I think the leak on this truck is where the hoses connect to the evaporator. AC wasn't working last year. I noticed a lot of oil and grime where the hoses connect. I pressure washed the area. After it was clean I could see that the hose assembly didn't mate up squarely to the evaporator connection. We took a chance with new o-rings. I know, taking chances in ac repair don't work.

Thanks for your help and we will look closer at the compressor.

Ice-in-tropics,

If I send you a picture of our setup can you tell me if it is like the leaky style you speak of?

Hey Hog,
Sorry for the slow response/delay, took a break to E Texas, working on fences, cutting down cedars to promote pines and deer food plots.
Sure, relay picture to me via Tim, but sounds like CCI compressor may not be the problem at this time.
Cordially,
ICE

The bearing is growling on this compressor now. Doesn't matter if the ac is on or off. Makes the noise all the time. Last time I looked at the compressor it had a lot of dirt collecting on it. I suspect this is due to leaks in the compressor.

I think I know the answer, but is the bearing worth replacing on this unit?

ice-n-tropics on Mon November 26, 2007 2:38 PM User is offline

On the York/CCI 2-banger the double row pulley bearing is doesn't rotate when the clutch is engaged because the pulley speed is the same as the shaft speed due to the inferior bearing mounting design. This pulley bearing would not be noisy during engagement. Look elsewhere for the noise source.

The belt is off the compressor. When I spin the pulley it is rough and there is a noise. When the belt was on you could hear and almost feel the growl in the cab. It didn't matter if the ac was on or off.

I did take a couple of pictures of the compressor if you need to verify that we are talking about the same type compressor.

I don't think I understand all I know about this. ;-)

Hog,
Sorry for the delay. I've been working up in Yankee land and then out this weekend getting a 8 point and a sow.
There is always a knocking/pumping noise and vibration when the York (CCI) compressor is engaged. Loss of oil will increase this noise.
The CCI clutch is mounted only to the shaft and the shaft bears all the belt load. Most other compressors mount the clutch bearing to the compressor front housing and consequently the bearing has relative rotating motion whenever the engine turns. So, perhaps your bearing (which has no relative rotation between the inner and outer race when the clutch is engaged) could be bad and the oil slinging compressor has noisy guts also, as well as a noisy external clutch bearing.
All this to say:
1st prize is the Sanden replacement kit discussed earlier (from AMA). his kit is sold by International but at a higher price than AMA will probably provide.
2nd prize is the Bergstrom replacement cast iron compressor from International but high price and troublesome.
Last resort- CCI and new clutch.
Best regards,
Old IV guy

As Tex has already pointed out, the Yory/CCI compressor is an old design with it's own quirks.

Since this is a class 8 truck, compressors are consumables. Replace the compressor, or remove the belt until you can because a failure could take the truck off of the road.

The simple repair is a new CCI compressor. Excessive belt tension kills the bearing assembly in that design, and diesel mechanics tend to tension the crap out of things like that. Use only enough belt tension to get the job done, and don't try to stop the belt from oscillating by overtightening it - the compressor has a crankshaft & two pistons, so the torque load is not smooth. I have seen a york type compressor destroyed in a week after a mechanic tightened the belt so that it "did not flop".

The aftermarket bracket to fit an axial piston compresor sounds good, but you may find the CCI lasts long enough on it's own if treated properly. How many miles do you have on the bad compressor currently mounted?

I think it is in the 40,000 mile range. Give or take a few thousand.

The belt has been removed.
