Difference between CH and CL series

Recommended Posts

I've been trying to figure out for the longest time what the difference between a Mack CH and CL is, e.g. a CH613 vs. a CL613. I know the CL series was offered with Cummins and CAT power in the CL733 and 53, but can't see any other differences

HI, a CH was built on it's own frame wheras a CL is basically a CH cab and a long CH hood mounted on a RW(Superliner 2) chassis. That is why the CL could accomidate Cats,Cummins, and of course the Mack E9 as did the RW. Hope this is helpful. Steve

Ch was more the road tractor and not really a severe service truck. Such as not having the heavy Axles for off road. Where the Cl is a severe service unit. Bigger axles and and configurations

When the CL came out it was offered as a "600" version for over the road applications. I do not think the lighter "600" versions were available towards the end of production.

In addition to what's already been stated, the CL had a 10" longer hood to accomidate the E9 and vendor engines, and it offered higher rated front and rear axles.

I always assumed the CL models had heavier axles and frames, but I'm glad that is confirmed.

Any idea where I could find literature on CL models? As a child of the '90s I want to restore a CL some day with a 454 Mack as a farm equipment hauler but I'm not aware of all the axles and transmissions that Mack had to offer, say between 1994-1996.

Not to change the subject but, Nick that's one sweet looking Dodge truck you have. There are a lot of CL's in northern Vt. Logging and grain haulers and low boys.

I like the dodge too. One just about like it in Diesel Power magazine. The colors are just reversed. Had to take another look because I thought it might be the same one.

There was a very similar truck in Diesel Power a few issues back, but with a lot of performance upgrades done to it and a pinstripe delete on the paint. I believe I remember reading the owner also lives in Ohio.

As far as my truck goes, I got lucky finding this one. I had been wanting an older diesel pickup since high school since the newer trucks are so outrageously priced. I'm not crazy about Dodge trucks but on the other hand, I like the pre-'94 models and the Cummins 12-valve appealed to me more than the Navistar 7.3. After searching Craigslist for months, I found my truck and learned it was only about an hour away from where I live, so I snatched it up. Came with the custom side-pipe exhaust that you can see in the pic, but otherwise unmolested as I wanted it. With the new paint it definitely turns heads cruising around in the summertime. My only regret is that the truck has a 4 speed slushbox, but otherwise I'm very happy with it.

Now if only Mack would make a light duty truck again, all my problems would be solved, but that'll be a cold day in hell.

Anyway, thanks again for all the kind words and information everyone

Out of curiousity whats so special about the pre 94 12 valve? I have the 98 12 valve. Probably one of the last ones built. I know they went to the 24 in 98

Well your '98 is considered by most Dodge Cummins guys to be the best of the 12 valves, since it comes with the P7100 injector pump and the upgraded interior that Dodge introduced that year.The pre '94s aren't powerhouses since they came with Bosch VE rotary injector pumps, which can only handle about 300hp safely. But there are a few advantages to the 89-93 "first gen" trucks.

First, those early engines allegedly are no different than the ones put into tractors, excavators, etc. so the internals are a bit stronger than later 12 valves put into Dodge trucks. In addition, the 89-93 trucks with the Cummins have a lot more room underneath the hood to work with; all the valves and injectors can be easily reached for adjustments which is a little tougher to do on later Dodge models.

Also, the 89-93 models came with the Chrysler 727 Torqueflite, which Mopar guys tell me dates all the way back to the 1950s. They're really stout transmissions that had no problem handling the torque of the Cummins, having been used in most Mopar muscle cars of the '60s and '70s. In '91 Dodge offered the A518, which is just a Torqueflite with an overdrive gear. It's the automatic transmissions that Dodge used in the following years that were so notorious for problems, so the '89-'93 trucks seemed to be the best choice as a work truck, at least for me.

Lastly, I've just noticed from my own experience that the earlier trucks don't seem to rust as quickly as the newer ones, but there's any number of reasons why that could be and it might very well have to do with how the owner maintains their vehicles rather than the build quality.

What I look forward to is the next (5th) generation of Dodge diesel trucks. Mopar has really stepped up their game with build quality since Fiat took over management, especially with their interiors, which in the past have been "tombs of hard plastic". Pair that with a new 8 speed auto and I think they might have a Ford beater.

Only thing I really want to do now with mine well a few things are put a more stought trans in mine. Like a 2 stick 6 but want something with a few more gears. My dad us going to be pulling a trailer and the 5 speed sucks. Hell put any kind of weight in there and take off going over an overpass and you really got to wind it out and it lugs down alot more before getting back into the power curve. Mine really starts building power at about 1900 or so. But being a 4x4 single cab I figure i need something longer to set it up how I want. Also I would like to get a banks system or go to cummins. Hell any high power diesel place which in South Fl we got a ton of. Looking to get better fuel mileage along with dragging the trailer with more ease.

yeah, if I ever need a tow rig I'll go with a Ram 4500 or 5500. It might be overkill but those medium-duty trucks offer a lot more in terms of gear ratios and transmissions, not to mention better mileage since the medium-duty "Ram" Cummins trucks use DEF. The 4500 and 5500 Rams come with 4.88 rear axles and Aisin transmissions which are a lot more stout than the autos found in a 3/4 or 1 ton. Still, I'd prefer a manual tranny with over 6 gears but that would take some ingenuity to get done.

What kind of loads does your dad haul? Sounds like he might want to upgrade to a medium duty truck at some point. Definitely pricier but better resale value, longer service intervals, and just about any transmission and gearing combo he could think of. I would just avoid getting a Freightliner; they don't seem to hold up too well.

He just bought an enclosed 20' trailer. Since I got the only thing capable to drag it around It gets to get a work out. Which is good since it sits for 3 or 4 months at a time and gets driven 1 to 2 weeks when home

Will a CH grille fit a CL 700?

Absolutely.
