Joey Mack Posted Friday at 09:08 AM Share Posted Friday at 09:08 AM They should be easy to find. P.A.I. makes several. Mack Dealerships are also selling P.A.I.

The Heinz Posted Sunday at 01:41 AM Share Posted Sunday at 01:41 AM We are selling PAI a lot now, they've been extremely helpful when Volvo falls behind on production, which is nearly every week. If Monday will be kind to me, I'll see if I can get a PAI number for you.

The Heinz Posted Sunday at 01:47 AM Share Posted Sunday at 01:47 AM Yeah, it'd be Monday. Their site's offline at the moment so I can't even log in at home.

Joseph Cummings Posted Sunday at 02:02 AM Share Posted Sunday at 02:02 AM Mack used to curse PAI. Called them substandard gray market parts 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74934-looking-for-a-rebuild-kit-for-a-mack-em7-300/#findComment-565446 Share on other sites More sharing options...
Joey Mack Posted Sunday at 02:21 AM Share Posted Sunday at 02:21 AM Yeah well Mack dealers have to suck it up. I have over a dozen Mack engines in a 20 mile radius of me that i built with P.A.I. kits in the last 8 years and i know they are still in service. I see the trucks off and on when Im driving around at work.. and none of the customers have called me to say the engines have failed. I stand by P.A.I. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74934-looking-for-a-rebuild-kit-for-a-mack-em7-300/#findComment-565447 Share on other sites More sharing options...
Joey Mack Posted Sunday at 02:22 AM Share Posted Sunday at 02:22 AM I also have a few transmissions out there with P.A.I. synchros, and no problems.. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74934-looking-for-a-rebuild-kit-for-a-mack-em7-300/#findComment-565448 Share on other sites More sharing options...
Geoff Weeks Posted Sunday at 01:21 PM Share Posted Sunday at 01:21 PM PAI must have got better. I used Interstate McBee, for engine kits, but don't know if they do Mack. I would buy the bayonet mount air gauges from PAI (I guess both IHC and Mack used these) and gut the case (only thing that went bad on mine were the little "ears" that held in the dash) and fit the IHC gauge in the PAI case. The PAI gauge itself wouldn't work with the IHC quick connect even though it was sold as fitting IHC. You had to re-work the case a bit for the IHC gauge to fit, but it was worth it.

Joey Mack Posted Sunday at 01:43 PM Share Posted Sunday at 01:43 PM as far as PAI engine kits goes, when I hold the parts in my hand they look and feel the same as Mack engine parts, I have compared the liners to each other using calipers to check dimensions and they are spot-on. The piston kit is also spot-on. the gaskets are great quality and actual has more gaskets in a PAI kit than the Mack kits. Pai includes head gaskets, unlike the Mack kits. plus the gasket and oring sets for both style oil coolers, and also has the balls for the piston cooling tubes, and the fuel crossover tube for the heads and the cam bushing set come with set screws thrust washer, and the rear cam plug, unlike Mack... I think I made my point..

880joe Posted Sunday at 04:29 PM Share Posted Sunday at 04:29 PM I don't know if this is true but I hear Pai has a better warranty covers parts and labor Quote Link to comment https://www.bigmacktrucks.com/topic/74934-looking-for-a-rebuild-kit-for-a-mack-em7-300/#findComment-565476 Share on other sites More sharing options...

Called them substandard gray market parts It's their and Volvo's fault. Your typical OEM expansion tank costs a cash customer $488.30. For a hunk of plastic that falls apart within the next 6 months it seems. It's no PAI but an Automann cross that has been reliable costs $169.81, you do the math which one people want. 3 1 Quote Link to comment https://www.bigmacktrucks.com/topic/74934-looking-for-a-rebuild-kit-for-a-mack-em7-300/#findComment-565556 Share on other sites More sharing options...
The Heinz Posted 10 hours ago Share Posted 10 hours ago Also, I wasn't able to get anything out of the number you gave me, I would need either the VIN or the actual engine serial (something like 5G4629). The serial's on the intake side near a boss.
