I had the same trouble with my E9 even before I did a power upgrade. I went through 2 new Meritor clutches in just a few weeks. I'm running a Lipe Clutch now. If you look at the pressure plate on the Meritor/Rockwell clutch the pressure springs are loaded on an angle where as the Lipe springs are loaded straight up and down. This makes for a stronger force on the clutch discs. Lipe Clutches a distributed out of Paris Tennessee and I have the distributors business card in my truck if your interested in a Lipe. If not you can contact Kelly Osborne in Riverton Wyoming (Osborne Trucking) he is the Mack service dealer for that area and he has a part # for a Meritor clutch that they run behind their E9's. I think it's rated at 1850 on the torque. I don't know if you have ever run into this, but the center on some clutches are too small and will hit the flywheel bolts. So make sure you get one that is compatible with an E9.

Where's it at in South Carolina? Where do you want it delivered and how much does it weigh? I have an rgn and would be glad to give you a quote on hauling.

I don't know the exact price of the Dale Francise headers but I have heard they are between 3K and 4K.

I met the guy who was doing the Superliner Registry. I can't rember his name but I have his business card in the truck and will get it for you it you want it. He told me that he had not had time to work on it due to other projects but was planning to get back on it. He works at Potomac Mack in Gainesville, Virginia. I was there one day about 6 months ago picking up some trucks for the Mack dealer in Charlotte, NC. My friend Dan was with me driving his CL with an E9. This fellow saw us pull in and he and his wife both came out to talk to us and take pictures of our trucks.

Mike Osborne in Riverton WY put a set of Dale Francis headers on his E9 and likes them. He runs his truck in the high RPM's anyway. He has a 2180 trans. and if it gets down to 1800 he splits a gear and pumps it back up. An E9 is a high rpm engine by nature(big bore, short stroke) and should not be lugged down, that's what breaks head bolts and blows head gaskets. Mike and I have talked about the headers but they are expensive. He recommends that I just try to improve on the manifold. Make something that flows out of the exhaust port rather than something that comes out and hits a brick wall.

10-4. Thanks alot. I've wrote your # down and I'll give you a call when I get up there. If your available we'll try to meet up for a cup of coffee and some good Mack Truck stories.

BOBO Thanks for the info. I'm going to be coming up next week. I guess I'll be crossing over at Niagara, PC Miler and mapquest say that's the quickest way from where I live in SC. I've never been to Canada before so I'm excited, also a litte nervous because I don't know what to expect. It's a good opportunity for me and I hope it will open up some new doors. THANKS!!

Customer wants me to take a load to Guelph Ontario, Canada. Got my passport, got a CVR# so I can get a temporary trip permit. What else do I need and what kind of problem can I expect. Oh yeah, my truck is a 1990 with a mechanical pump. My buddies have checked with their companies, one with Landstar and one with Mercer, and they say I'm exempt from the speed limiter law.

Sounds like you need to talk to JR Collins. He's got a lot of technology tied up in the Buckeye Bulldog, but I think he told me they a running a special cam and lifters but the heads are built with standard parts that you can buy off the Mack shelf and he's turning that thing between 5000 and 6000 rpm's.

Brick Haulers Inc. (BHI) out of Forest City, NC used to had some glider kit KW T800's with Mack rears on Camelback suspensions.

I'm not sure what a H5ca is but I know a Holset 4C is a bad boy. Stay away from the 610(5134) turbo. That thing spooled up real fast. It started making power around 1100 rpm and by 1600 rpm it was played out. I wouldn't recommend it for a pulling application or a over the road truck. I've heard of people blowing that 610 turbo up on hot E7 400's. For a pulling truck you might need a HT80. My engineer friend says a HT 80 is a 4C on steroids!

What's the best gear lube to run in a set of Mack rears. Been running synthetic 85-140 and just lost my rear/rear again after only 14 months of service.

The air ride suspension on my 1990 Superliner has gotten out of whack. We replaced the suspension about 4 year ago with a 2000 Hendrickson/Mack air ride out of a CH. The only problem is that the truck we got the suspenion from was not mine and I don't have the vin # to go by. Does anyone know the proper ride height for a 2000 Hendrickson air ride that's under a 1990 Superliner(double frame) and is it even that critical?
