This was destroyed a while back, but Im just now opening it up to see exactly what happened.

Was the first blower I put on the famous "Mercedes" tm.
Enjoy.

thats weird. what made it do that?

 

[AshleyMckendree]

I think it was the vibration from the Mercedes diesel engine LOL.

 

[amazingcleansc]

what was the engine from?

 

[AshleyMckendree]

what was the engine from?

It was a rebuilt 4 cyl Diesel engine out of a 1983 Mercedes 240D car.

I may still have pics, as the ones posted here are gone.

how would gears "vibrate" out of time?

You would know what I was talking about if you ever saw the Benz TM in operation... :mrgreen:

That thing looked like it was possessed at lower rpms.

I doubt it was the vibration, but it sure as hell didn't help.

My Big Red Suterbilt 5M broke some teeth just like that. It had a hackish oil drain on the blower when I bought it and not knowing any different, just left it as was. One day the oil drained out. Never ran right after that even after a rebuild. Boy did it clunk the last time I shut it off.

 

[AshleyMckendree]

I just realized I never had to drain any oil out of the back to look at it... must have been what happened.

Ashley, I must admit I don't remember ever seeing your custom-built truckmount, did you ever post pics? I tried a search but couldn't find it.

The pics I posted here are gone for some reason, and I cant find them save on my hard drive.

...it was a monstrosity

I'm still learning, but was there a shaft directly driving the blower or a belt?

Belt driven.

Hi:

If the blower is still turning with the lobes missing each other, it did not "jump timing". Also a Suterbuilt has pinned shafts to hold timing, not lock nuts. I'd guess that one, or both of the lobes locked up.

Thx,

Thanks Dale! Do you know If a bearing distributor would carry those gears?

 

[RodneyBeach]

From what I have been told the problem is that you have to have a special tool and really know what your doing to set the timing or the bells inside will slam together and crack or bust the teeth off the new gears. I really don't know, I was going to rebuild my roots blower but ended up paying to get it done.

Good Luck, I hope it all works out for you.

Hi Ashley:

The gears have to come from a Suterbilt dealer, unless you can find a used blower with a different problem. What size blower is it?

I was given a whole bunch of 4.7's Roots, that need rebuilding from an Interlink
store. Roots won't fit Suterbilt, but it shows that if you can ask a TM dealer if they have any bad blowers...

Thx,
Dale

 

[bob vawter]

those gears are press fit onto the shafts with NO key location to go by...
BTW...On that last blower replace that i did wit the pics....i never got a pic of the INSIDE.....
the shaft was sheared all the way through the impeller... all turnnrt fine..except the lobes........
it HAD oil in it...and had been greased......never see a sutorbilt do that....
i DID replace it wit a Roots!

 

[GeneMiller]

I was told a while back that they are considered disposable blowers at that price range. It costs almost as much to replace just the bearings as buying a new one.
