Best E9 clutch

[wrenching4life]

Hey all looking for some imput for a clutch, currently our Superliner has a LIPE clutch but the throw-out bearing let go and now I am looking for a replacement clutch. Im having a hard time locating someone that sells a clutch that will handle the torque our E9 makes. The LIPE supposedly is rated at 2400 ft lbs. so I figure I should shoot for that rating or better. The truck is street driven, and hauls heavy. I dont want it to slip and I need it to hold the power! The part Number on the LIPE is 380 702L0989

Thanks all.

You want a new coaxially dampened ceramic button Spicer.

Mack model number CL7984  (part number 11HB59P120)

(9 spring / 6 paddle 15.5'" discs)

Spicer number 108935-94

Can get a Lipe with higher rating

There's a guy western Pa that will make what ever rating you want Joe Richie is his name can try to get his number if you want

Unless the engine has been modified. stick with the Mack spec Spicer clutch that the truck was engineered with. Don't second guess Mack engineering. A new 108935-94 is exactly what's needed. Mack never installed Lipe......they don't offer a Mack spec clutch.

The Spicer clutch I speak of is not an off-the-shelf clutch from Spicer. It was built by Spicer to Mack engineering's specification, and was never sold to any other OEM.

If you have juiced up the engine above 500 horsepower, buy the 108935-15. But if you haven't, don't buy it.

Yea the motor has been modified, iv done a lot with it, it's well over factory spec. I had no complaints with the LIPE that was in it just wish the throwout bearing didn't decide to pack its bags and head south.

If you want to enjoy that Mack V8 for many more years, then turn it back down to stock spec. That's adequate power. Otherwise you're going to be needing parts that are either NLA or cost a fortune.

I am learning that lesson right now as I rebuild 2 E-9's!

Black in black I would like to give that guy a shout if you have his contact info. Im told what I need is a LIPE 1. What clutch do you run in your truck? I also heard that Dale Francis has a clutch set up he uses that requires the flywheel to have some custom machining done to it, but its supposed to be rated for big power.

[kscarbel2]

Come to your senses, turn the fuel back down to stock, and use the appropriate Mack spec Spicer clutch.

Don't place yourself and Dale Francis above the Mack engineers who created the E9.

Sound experienced advice about E-9 engines and set up is hard to come by,  worth serious consideration, I have been talking to an experienced Mack guy, he has a long history and his advice is same as Kscarbel2 - he also says that E-9's should be run as set up at the factory and cared for properly as well - then you get a long happy use

[wrenching4life]

Thanks for all your input, I appreciate the responses.

I had the Lype behind my daily driven v8 at 740 to the ground. Work very well.

Yet I agree turn it back down some longevity with these engines to day are paramount. Parts and prices.

I am running into this issue now.  My motor was originally 400 hp (now marine injectors and pump cranked all the way) and has the tiny 7 inch ID Flywheel which limits you to 1400 ft lb clutches.  I think i am going to open up the ID and balance the rotating assembly so i can run a big eaton clutch.  Dont turn it down have fun with it.  Treat it right and itll be just fine.

[kscarbel2]

Yet another one who knows more about Mack V8s than.......Mack engineers. Some people just have to learn the hard way.

[Superliner92]

Yep... I don't anticipate my engine to last 1,000,000 miles.  In fact that's why i have a spare and spare heads.  If you want your engine to last forever why not turn they fuel down to 50 hp?  It's all a trade off.

I guess by this logic Mack engineers designed the e9 to spin rod bearings and drop valve seats on factory hp engines for some reason.

Bottom line is everything breaks. If you want 2000hp do it, if you want 3hp do it.

There is NO right or wrong here Guys. The fact is that the E9 was a good engine. It did have problems just like any engine. I recently have been talking to Steve Trevitz about my E9 that he personally spec 1500 hp at the flywheel, I have since turned it down a few hundred HP. Yes I have dropped a valve seat... on a Reman head with 18K miles on it. It is known that the press fit on the seats needs to be on the tight side of spec or more. The biggest issue with the E9 was when increasing HP not everything was modified to do so and with operator error bad things happen. This is directly from the MACK engineers mouth... Steve was the E9 engineer from the start of the E9 to the end of the E9 at MACK.

Steve is a MACK engineer and still works for MACK... oops... VOLVO now. He was the design engineer of the 4 valve head that turned the 866 plus some cubic inches into the E9 and its variants. I have ask him for some photos and information of the creations that MACK was involved with, there are many. Most of these included multiple turbos, bigger injectors and 13mm pumps. Marine, over the road and military were the main uses. Prototype rated at 360hp, production Rated at 400hp@1800rpm to 900hp@2600rpm with reliability and continuos use in mind right from MACK. I may get info on these engines some day but Steve is to sick to even dig that out at this time, 20 years after production stopped in the USA. No not ill but the engine had so much potential and was abandoned by VOLVO (me saying that not Steve) to promote their 16L engine.

With power abound just like the 350 Chevy that started at 170hp and now over 650 hp today from Chevy, well over 1200hp race. If all engineered correctly it is no problem to tune engines up if needed. The fact is that correct information or really any information was not released from MACK to do so. 

Just to put it to rest the engineering and  information was there.... at MACK.

 

On a clutch's, I got a 4400lb LIPE in the Superliner, works great, just a workout to push. I thought it was a beefed up stock clutch with ceramic pads not special. It is cast iron and is NOT a competition unit by todays standards. No cast flywheels or pressure plates in anything but street class pulling now. A multi plate slipper clutch is the way to go for big torque capacity, ask Back in Black, think he has had one for several years now. Dale Frances can get one together with billet flywheel for an E9, $$$

We just installed a clutch supplied by the customer  from paccar  http://www.eaton.com/us/en-us/catalog/clutches-and-brakes/easy-pedal-advantage-clutch.html  available in  Variety of ratings up to 2250 torque Very reasonably priced worth looking into in my mind! Our Mack/Volvo  parts people couldn't come close in pricing!
