Must be a stark white Mack on a stark white background? Maybe I's be blind? Rob

Maybe that is referred to as a "Love/Hate relationship. Rob

You can and they are expensive. Last I checked it was pushing $300.00 for a piston rebuild kit. They are a size "20" chamber. Rob

Just think: a company capable of putting out a product like this and instead puts out the likes of Peterbilt. Where is the pride? Rob

I'll see if one of the copy shops in Peoria will do the job. I could but it would certainly take a while. I may just scan it in and make it available soft copy in .pdf format. Rob

Find a dirt pile out of a dump truck. Mash it a few times easily with the front tires, then ease into it. Rob

I have a TS-442 from the very late B, and very early R series trucks I could copy for you sometime. Rob

Heat will help but not the concentrated flame front provided by a cutting torch. I would use a "rosebud" type tip to be more even. Don't heat the drum much past a very dull red and keep the flame moving. When the complete drum is too warm to touch, tap around the inside perimeter on the outside of the drum to allow the frequency of vibration break the sucker loose. If you have a large three jaw puller this would make it easy. The hub and drum are an assembly until you have it on the floor. Then you can separate the pair. Rob

Glad that worked for you. I use them a lot for harnesses and such. Their catalog is about as thick as a dictionary. Rob

There is an R700 in NV I could use brought home.Rob

I forgot to mention gravel or dirt!! Not asphalt or concrete as you don't want to break anything. If you lift one axle only that axle will spin. The power divider actually bias the driveline torque trying to keep both axles together yet allows differential action between the two for turning the truck. On gravel or dirt, the truck should try to keep both rear axles trying to pull the truck and being unable to move, should spin both sets of drive tires, (on set on each axle). If it won't hold the axles together during a pull, it is shot. Another trick I like to use requires a sharp incline. I attempt to drive up an incline to see how far I can progress till the front axle starts to spin. By design, (I'm told) the Mack power divider should be able to make a single axle hold approximately 70% of what both axles can take. Typically in a good setup, I can almost get the front axle to start lifting from the ground before it starts to spin free. This is true in either forward, or reverse. If the torque bias isn't correct and working, nothing else about it works right either. Wear can cause loss of traction and certainly a driveline vibration as this thing is always working in series with the driveline torque, both on, and off power. Rob

I like to butt the truck up against something solid, or chain it down to check for torque bias. Basically make sure the axles want to pull together and spin tires together. If that passes alright, pull it apart and look at the peanuts and drum for scoring, or wear in the "gullets" meaning the high and low transitions of drum and the cam housing for deformation. These are wear items but if it is not smooth in operation, (meaning binding) you can get a shake or bounce originating in this unit that is difficult to track down. Rob

Try mouser electronics, www.mouser.com first. They have a bunch of oddball stuff. I'll get you a few more vendors tomorrow when I'm at work but that one probably has what you need. Rob

I've seen a lot of drums new, and out of the box be off in balance. Some as much as six ounces depending on size. As they age and wear, it is a definate possibilty of being off. However, the circumference in which the unbalanced condition occurs is much less of a problem near the hub, as opposed to the outer surface of a tire where the actual speed or surface feet per minute is much greater. I've had drums sandblasted, then turned true, and then balaced on my tire machine and acheived satisfactory results. I can only go to about 1/8th ounce accuracy using this method but it's close enough for who it's for....... Have you looked into the power divider yet? Rob

Don't mean to be a smart ass but it's only worth it's weight across the scales unless you can prove it to be a good unit. I would hesitate to advertise it without knowing it's true condition. Rob

Slurpy!!! Rob

I hear "motorboat" sounds in the background. What have you been teaching that gorilla? Rob

Battery technology has radically changed in the last 20 years or so. Although similar in size and function, a battery built today has much greater capacity and reserve than something produced years ago. Back in the 1970's a 750CCA storage battery for an automobile was available but rare, and needed routine service to yield a decent lifespan. Today's batteries with "sponge lead" technology used, absorb and hold a much deeper saturation level in the plates, and can be sealed not requiring routine service, (within reason). Shock absorbtion is another arena with significant improvement. Vibration is the second most destructive factor in a storage battery and todays units accept it much more readily than the formers. Heat is the greatest enemy of batteries. I run two 1100CCA batteries in everything diesel with the exception of the Cat powered RL, this one will still have three as the engine uses glow plugs for starting. Of course the analogy of "You get what you pay for" still applies. I've seen group 30, and 31 series batteries sale priced at $65.00, and double that. There is usually a reason behind the disparity.

Smart woman. I'd keep her. Rob

I'm certain with another bottle of Other Dog's special sauce, he could be convinced. Rob

IN RESPONSE TO THE E-MAILS CONCERNING MY DOG... Please be advised I am sick and tired of receiving questions about my dog who has mauled six illegal immigrants, four thieving politicians, two muslim clerics, nine teenagers with pants hanging down past their cracks, eight customer service desk people speaking in broken English, three flag burners, three ‘travellers’ calling at the door with lucky heather and wanting to ‘tarmac yer droive’, and a Pakistani taxi driver ! FOR THE LAST TIME... THE DOG IS NOT FOR SALE ! Rob

Naw, he has an acute infatuation with "African Termite Mounds".

No need for concern. It would handle it. Rob

My thoughts exactly. Rob

Phone is always on and I'll expect his call(s). Bout the third time he calls for roadside assistance I'll give him the contact information of a guy in Peoria that specializes in fixing those things so they stay fixxed. I get a pretty good "kickback" on the proceeds for my services so please do pass my number along. No worries about the stacks, boxes, or storage closets full of receipts and invoices for past repairs. As soon as I know the vin of the truck, "Momma" can recreate the paperwork for any repairs paid for by a Caterpillar affiliate and I can work with him to get the best scrap pricing available. All in the name of helping an unsuspecting, or duped guy out, you know. I just turned the ringer up really loud cause I'd hate to miss the call. Rob
