I created a short video of myself double clutching the bus and would like to hear your comments on it. If it is a good representation of double clutching pass it around to those that may need a visual learning aid in addition to the written instructions out there. Here is the link: http://www.youtube.com/watch?v=p--jE1cfhj0 . | ||

hey austin, cool video, however I believe that I would lower the seat so I could reach the pedals a little better that tip toeing n the accelerator haaha. If you want to know if your are shifting properly put a 3/4 full glass of water on the dash and if you spill it you are not shifting smooth enough. My dad wouldn;t let me drive his rig if I spilled the water. that was embarrising too.. cool | ||

Thanks Marvin, I usually have my foot farther back so it is in full contact with the pedal. I moved it forward up on the pedal to allow view of the clutch pedal action. It may have been a little high. Once I'm on the highway and lock in the "cruse control" throttle lock, I raise the seat for a more comfortable ride. I sometimes forget to lower it back down when I'm back on "surface" streets. The only time I have spilled my coffee is when I hit a bump in the road while turning. So I guess I'm doing OK. | ||

Hey Austin ... just a couple of comments. If you're running a clutch brake, you only want to depress the clutch pedal about half way down, not to the floor. Going to the floor will burn up your clutch brake when shifting. Also you shouldn't rest your foot on the clutch pedal after you've finish running though the gears, this is hard on your throw-out bearing. Good job Austin Ron | ||

Ron, Not sure about "clutch brake" What is it/how do I check to see if my bus has one? The clutch is air assist. When my foot is resting on the pedal I don't think it is depressing it at all. I'll pay more attention next time I'm driving it. Great feedback, keep it coming... | ||

Hi Austin .. clutch brakes stop the tranny from rotating and allows you to put the tranny in gear without grinding when you're sitting at a stop sign or warming the bus up in neutral. If I remember right it’s on the tranny side of the clutch in the bell housing, it’s only about 4 to 5 inch in diameter and the newer ones are split in 2 so you can replace them through the access hole at the bottom of the bell housing without pulling the tranny.

Ron - Austin's coach does not have a clutch brake. GMC added those when they went to the wet-clutch models, and the 4104 uses a dry unit. (Most of the clutch brakes failed quickly, btw - poor design.) Austin - Nice video!! FWIW & HTH. . . | ||

Ron, I don't think I have a clutch brake because the gears do have a tendency to grind when first put into gear after idling. John, I'm not sure that 0-60 in 62 seconds is the true time. I did do some editing of the video. But you bring up a point I've been wondering about. This being my first bus, I don't have anything to compare it to in the way of performance. It seems slow and sluggish. What is the average 0-60+ time? | ||

Austin - "What is the average 0-60 time?" For a 4104 like yours, somewhere in the neighborhood of three to four days. . . LOL!! Seriously, the only 0 - 60 performance figures I've ever seen for a bus were in the April 1969 edition of Road & Track magazine, a copy of which I have in my files. The 8V71-powered, four-speed MC-7 turned in an astonishing time of 87 seconds for 0 - 60. And for you real speed freaks who like drag racing, the 1/4 mile time came in at 32.8 seconds at a blistering 44.5 mph. FWIW & HTH. . . | ||

RJ, I'm sure an MC-8 would be equally as slow. I saw a road test of a bus in a car magazine, but it was sometime WAY after '69. It must have been sometime in the mid- to late '80's. I believe it was Car & Driver. I'm sure I won't find it, but I did keep most of my magazines (like just about everything else). I'd be curious as to the 0-60 times on some of the Series 60's or 8V92's... just out of curiousity. David | ||

im sure every coach, even stock, would be a bit different depending on about a million different variables. i know that my Eagle 10 w/ 24.5" tires, and a 350hp 6v92TA/740 combo is a dog off the line, thanks to the turbo, but once im over about 30mph she picks up speed a bit better(but not much, HA!). if im running down the highway @ 70mph, and i come up behind a truck, when i move over and floor the pedal to pick up speed to pass, it takes me 20-25 seconds to just move past the truck, not including the extra distance i need before i can move back over safely. arent these speed demons fun? lol. kyle in norcal 1980 Eagle 10 #30223 | ||

Let's see you downshifting. Now that would be good for newbies to learn. Talking about what to do, RPM'S, etc.. Paul 1968 Eagle 01 #7443 | ||

Paul, I have to get better at downshifting before I put it to video. Besides I don't have a tachomenter or a working speedometer. . | ||

Marvin, I forget what outfit it was but they would put a bowling pin on the step beside the driver...if it fell over 3 times during training they sent you packing. Try that sometime. Last year while doing a senatorial campaign contract I had a stack of 4 quarters on the dash for two months......didn't move a bit | ||
