Get that jeffco apart yet?

yes we did friday night and i am going to upload the raw footage to youtube in a few and post it. talked to shawn at jeffco and he said jon is only the third person to snap that shaft.  sounded real when he said it lol but since jon just got this back 1 year ago and only has three trips on it shawn said he wants to verify that and if so he will warranty the parts.

[fabr]

The reason he is only the third person to snap the shaft is because there aren't really that many trans out there.It's not like any of us are putting out shit loads of HP. I mean,realistically,we aren't making but 220,maybe 240 HP and the torque is almost none.    Add to that ,enemy's car is light weight. Wheelies or not,we just aren't making any serious power.Oh well,if jeffco is fixing it on their dime,I guess enemy can get yet  another partial trip out of it.................

[dsrace]

i agree one would think that box capable of a lot more and the only thing i can think of is the pounding they take from the woops or choppy ground otherwise heat maybe? but jon has figured out how to get the heat way down in the box. the weakest link in the box up until this last update was the bearing in the idler gear and his custom gears weren't strong enough then he got with weddle to strengthen up the gears and now they seem to be real clean with no visible signs of wear. nothing will beat what you've designed but it will be interesting to see how the next few trips do with this box. he got 3 trips out of the last tear down lol  but after you see the video you'll know why so soon this time anyway. you are right we are not putting out much of any tq and little enough that a fully weddle built t1 trans is rated for, hell the rate the fully built t1 w/weddle gears to 200 ft lbs tq. which makes me wonder why transworks couldn't get that unit right!!

[dsrace]

fabbr did you stop and take a look at the sand bullet rails with the gear one reverse box's? i installed one for a customer back when they first came out. poor machined parts kept it from running even once before it was shipped back to be fixed but i liked the concept of it. direct couple however that love joy coupler was never strong point imo. i think they could've came up with a stronger way to couple them. had some other snags installing the unit and had to get with sand bullet 5 or 6 times along the way to work with them to figure it out as they hadn't yet either lol i won't bore anyone with those issues but in the end when the box kept popping out of forward and reverse they finally just told my customer who lived 30 mins from them it was because the unit wasn't installed in one of there frames so they weren't going to warranty it!!! had to put a stout lock on the shifter to keep it in gear.

[dsrace]

are the rpm box's straight cut gears?

[fabr]

Didn't look at the trans. RPM are straight cut gears. Straight cut carry a little less load than helical,make noise but with the advantage of no thrust loads to deal with. Easier to design from that standpoint and fewer bearings to fail in the unit.

[dsrace]

gear one made the units but sand bullet assembled them.

[dsrace]

still processing on youtube  so prob a min or two

[fastcorvairs]

what is that big grove in the shaft? E-clip grove?

Will the results of the video gained me one more X on the tow strap.  What is that now three? lol.  But you have to admit it was a nice clean pull this time.

[dsrace]

lol that was an easy pull back and that pic lol

   as best as i can tell the split washer drops into that groove to retain that gear but no snap ring in the other groove. shawn said he made a change to that groove so we'll see as he said if it was indeed last year he rebuilt it that he will warranty the shaft. it really looks like it has been fractured for a while from the discoloration from the oil and i believe this is the 4th time.

[BDKW1]

and the torque is almost none.   

Only 570ish FTLB's in first gear from a stock Busa motor. Should be easy to make that work, shock loading be damned..........

ONLY TWO! But please reserve some space after my last signing, I dont want to have to go searching for a new spot to do some Sharpie work'
And it WAS a very nice pull back to the camp! The fragrance of e85 is quite pleasant when it is not being blasted at the schnoz at 20+psi in the dark

He's doing wheelies in 5-6th gear.

[dsrace]

He's doing wheelies in 5-6th gear.

i was about 1/2 to 3/4 throttle in fifth when he passed me riding a small wheelie in 6th gear....passed me . that was two trips back.

[Enemy]

Fast started it! I was just chasing the smell of corn this time.
Still amazed those China paddles can do that missing a few paddles lol. 9 years old and money well spent!!
