installed my new 3250 dd, how should i break it in?

[jaybuller]

i just got done installing the new sb 3250 street DD with the 1 3/8 input upgrade. now how do i go about breaking in this clutch? to much money to go out and glaze this thing over...... just easy driving for a while or load it down at first to seat it? thanks

I went straight to a pull when I had a dd clutch and didn't hurt it.

Drive it like you stole it, always worked for me

[Snedge]

Yeah... and if you have trouble you can tell the manufacturer that the guys on the internet said to do it this way.

Hey JB... I'm not trying to be a dick, but call them. It might even say something in the literature provided with the clutch.

I would go empty truck city driving for the first 100 miles. Engage and disengage that thing as often as possible. Then drive it like you stole it.

That's why I posted in the sb section so peter would answer it. He wouldn't answer the phone

Generally a street dual disk or regular single disk is 200 miles of stop and go driving to seat it in correctly. Then you can cut her loose and raise some hell!

I don't think Peter get's on here over the weekends if you still want to talk to them calll first thing Monday morning! Leave a message for Peter or Mansil if either is not available to talk to you at that momemnt. I PROMISE YOU you will get a return phone call before the days over. I call them on a regular basis to shoot the breeze, and price stuff for friends. They get SLAMMED all day on the phones.

I think Peter will tell ya to slip the chit out if it from the get go and have some fun with the ceramic material if you baby it too much you'll do more damage the good.

Just curious, are you sure your not confusing Sintered Iron with Ceramic? I've never heard of slipping a ceramic lined clutch being good for it?!? Ceramic is organic material that is less grabby than Feramic or SI for smoother engagement.

when ordered it, there wasn't a break in period.

He also told me I was being to easy on my 3250 12cb DD. start using 2nd to get going and slip it a little when I visited SBC last summer.

[jaybuller]

well it is nice and smooth, lighter than stock pedal feel. i am gonna drive it easy till i get the word from Southbend. i always do start out in 2nd gear to get rollin anyways but i like how it doesnt have any shudder at all when taking off. I wont tow anything till its broke in, hopefully he will call me back by monday.

[MegaCabRam]

did a couple 3rd and 4th gear burn outs on my #3850 south bend with only 2 miles on it, never slipped once and it had a hard life

[jaybuller]

i prolly wont be doing any 3rd gear burnouts ever, but im glad it worked out for you. i dont believe with all the weight of the flatbed and tool boxes this thing would even do a 3rd gear burnout on dry pavment anyway.

[tarter6bt]

I drove mine around town for a couple days hit every stop light I could then. All hell was broke loose. Pullin trailers racing 2nd gear launching you name I done it. I put it to the test

yea not saying i recommend it, just that not allowing a break in period didn't seem to affect mine, could be a little different with the smaller plate load...

Just checking I have always been told 200 mi on a DD type truck from SBC. Now on my fresh Sintered Iron waiting to go back in I was told to do a burnout, let it cool completely, repeat, load on trailer go to pull!

Hey all. I'm down in Florida this weekend and enjoying the weather. Break in on a street dd is not super necessary like a single disc. Towing is actually a good break in procedure. Remember the street dual disc are not meant for competition and not designed for slipping the heck out of. They are for holding hp and towing heavy. The new slipper sintered dd's and ddd's? Have fun and hold on. Be back in the office on Monday.

Peter

[jaybuller]

thanks, im just driving it like i always do then(always start off in 2nd, slip it out just enough to make it a smooth take off) thanks for a great clutch im fallin in love with it the thing does not make any noise whatso ever with the clutch in or out and is smooth as silk. Also there is no vibration at all in any gear or speed like i have heard off. the only thing i have noticed is it does take a little longer to shift gears. but i dont race or anything so i dont mind at all.
