Hi to everyone,

first: I've got this clutch (on a Dana 4484 tranny) that I'm trying to adjust... I'm finally able to pull 'up' on the adjustment knob - the one that's located behind the alternator - but it won't turn, or just barely.

I'm still at Howard's place and waiting for him to come back in order to try to turn the arm with a pipe-wrench if he's got one (do you think that's okay?).

Any other thoughts or suggestions?

BTW, We've got the toilet!!! plus the drains for the sink and shower installed. Everything's coming pretty good!! Slowly but good.

To EDNJ: it was nice to meet you too! We had a nice time. Gosh, my first gig since this weird adventure began... glad you all were there!!!

p.s. I miss you guys... haven't taken much time on the computer...

Nellie

- no first hand comments on the clutch adjustment solution other than perhaps apply penitrating oil if possible and give it time to work, or maybe apply some heat from a propane torch (without starting the grease & oil on fire & do not contaminate the clutch material itself ).
...what I really wanted to comment on was how wonderful it is to have a toilet on wheels, with the almost dog like ability to pull over anywhere and have a good crap, with all the decadence and comfort of a human throne. Keep on converting, singing & busing Viv...

p.s. have a funny April 1st everyone

Everyone should be issued a case of PB BLASTER at birth. Nothing in linkage should be frozen that tight. If it is,,, have a pro mechanic take a quick look.

The clutch can't move if you don't hold the pedal to the floor. Sometimes they even bind then and you have to come back off the floor about 1/2 inch.

That is sure nice to know, thanks Larry! I'll give it a try today.

David, I agree with you, that PB Blaster is something that should be part of everyone's life as soon as landing on this planet!!:-)

Hey, Ednj, thanks for the info on the phone today... I called before seeing your post, but probably would have done anyhow (to ask about your "that is not the linkage adjustment" comment.) Soo, exactly what does the adjustment knob actually adjust??

My concerns are 1) that there is no 'free play' in the clutch pedal (pretty tight from top to bottom) and 2) that it hangs up (not always) when I let it out.

As for concern #1, I wasn't aware that 'free play' was important until my friend Ralph explained it: said without free play I'm riding my throwout bearing (whatever THAT is), kinda like driving with my foot resting on the clutch.

Okay, so now that's become a concern.

But my original concern was #2. Are the two malfunctions connected, or are they separate problems?

To clarify, the clutch works smooth enough... doesn't chatter and doesn't slip, and allows non-grind shifting even when going from neutral into first or reverse. But when it sticks, I have to give it a little tug with my toe and then, of course, it 'pops' right out. Not so horrible if I'm up to speed and just changing gears upward, but really awful if I'm at dead rest or downshifting.

A note: The pedal never seems to stick when the engine is off. Go figure?

IF I can get some free play just by adjusting the linkage, will that alleviate Ralph's throw-out bearing concern... or must I also adjust with that adjustment knob (which still won't turn)?

Safe trip, Ednj... I look forward to hearing from you (and Mike) tomorrow.

Ohhh, almost forgot (again): Thanks for the encouragment and good wishes, Clint. And, boy, you're right on about that toilet thing. Nothing like a little decadence here and there!!

Thanks again, everybody. See ya soon...

...perhaps your in need of a little grease at the pedel pivot bushing and all other linkage points that need it, even if there is some binding at well worn parts a little lube often does wonders. Climb in there and have a good look (after a good stucy what the book has to offer as lube points on the charts & diagrams.)

We can always hope & try with the "see ya soon" possilbity; much like the maintaining & converting our buses & every thing else we set our minds too.

Do you have a clutch assist cylinder? When I had the clutch overhauled, the shop didn't fit the operating lever snug against the housing. This allowed the assist cylinder to move sideways and bind on a projection on the housing causing it to "stick". Didn't happen often, but took me a while to find the problem

There is a grease nipple on the adjusting mechanism.

Also, if you do have the assist cylinder and the geometry is not exact, the air pressure may be causing load on the adjusting screw. It probably shouldn't matter if the air is up, but I find it easier to feel when the load starts to come on as the wheel is adjusted if the air is down.

Are you positive you are lifting the wheel enough. If not up enough, it may still be engaged in the locking lugs.

I know at least on big rigs, that the linkage should never be adjusted. All adjustment should be in the clutch. This is because truck clutches have clutch brakes on them, and if you adjust the linkage, the clutch brake will not work properly. I don't know if an older bus clutch has a clutch brake. Good Luck, TomC

Interesting comment, Tom...think I'll go to the manual and check that out on the Crown. (I don't need that adjustment....far as I know)...but who knows when???

Thanx for the tip. :-)

Larry...can't xactly agree with you about holding the pedal to the floor... in fact far from it.... one of us has a,,,"problem"?? Hmmm.
