Lenco burnout procedures

I have a cs1 3 speed that has been eating clutch packs . I think we have solved that problem but was wondering if shifting the Trans from 2nd to 3rd in the burnout is wearing on the plates a little more . Seems like starting the burnout in high gear makes more sense .... Any of you guys doing that or have done it ?

 

I'm always in high gear for burn out. Rev the motor to 3500 or so a dump the clutch. 7500 to the 60fy mark. What is your clearance in the pack. .080 tightest- .100 loosest. Air shifted or levers? Air pod should be backed out 1 turn. You ever pull the towers with the lever and fish tape?

 

I've done this for 7 years with Lenco and clutch. Never once burned a clutch pack up.

 

Packs are at .087 & .090 ..fish scale pull is 45 & 50 . One turn out on pod .
Thanks for the help ,

 

Is the puller backed 2 turns out then pulled? Are you running any kind of air restrictor in the pods?

 

Yes , 2 turns with no restrictor in pod .

 

Might be a stupid question but what oil do you have in the CS1?

 

What shifts the trans, Clipper buttons or ACD controller or? Always high gear burnout. The old recommended shift in the burnout was for low horsepower, normally aspirated engines that had less power.

 

Same here, start in high gear. Some of the low hp cars I have seen start in first and then pull right into high gear, passing over 2nd.

Clipper buttons , I'm sure I've been hurting the packs some by shifting mid stride ... We did a burnout the other day on a fresh pack & didn't get to make the pass , I repulled my fish scale before the next pass & it was off quite a bit ... That's what's got me looking .

 

Honestly I don't think your setting it up right. To burn up between the burnout and staging means it's killing itself quickly. Is anyone around you who could give a second set of eyes ? When you measure the pack are you pulling the spring out and pressing down with both thumbs, having someone read the calipers , then subtracting for the snap ring?

 

John, put a pressure guage at the shifter pod. Watch it while someone pushes the shifter button. If it takes over one second to reach full pressure at the pod, you have a restriction (regulator, line, button). Also, on the Hypermaxx car, I run the shifter pressure higher (due to the car weight vs. tourque), between 190 and 195 psi. Tranny lives good in a car that weighs 1000 pounds more than yours. Call me if you need anything.

That's exactly what we did & that was the problem ... The guage would go half way up & had a quick pause on the way to 200 .. The lines we had hooked to the shift buttons were a coil style / soft flexible hose ... The hose was expanding & dropping psi for a nanosecond . We had ran these hoses for years in the Funnycar but I guess the extra distance back to the trans made the difference ... I like learning stuff the hard way

 

Yes sir we do that , I measure from the top of the ring & deduct .060

 

Jay maybe explain subtracting the snap ring for him. Its hard to read sometimes.
