jerico 3-4 shift arm lever issue

[JHeath]

Brad Zaskowski has broken 3rd in his Jerico 5 times, he reported on his Facebook page, after he lost in the 5th round at Joliet, due to a broken third gear ( he has an in-car video of it breaking) Charlie Westcott told him not to burnout in 3rd, it is the least supported area of a Jerico 4-speed. Oh, and Charlie said to do burnouts in 4th gear.

I suspect those that have excessive base and / or counterweight are prone to breakage at any point on the track, even on the burnout. Of corse "excessive" is a matter of opinion, but the more pressures that are applied, the harder it is on everything.

The only thing I've ever broke in a jerico is 3rd gear also. Must be the weak link on them. I also do a 3rd gear burnout. Its one hell of trans though, the torture we put them through lol.

If anyone has ever seen Charlie do his burnout, he shifts 1-4 in the box. check out any of his in car vids.

You can do that with a clutchless.

He's also using the Jerico Hybrid 4 Speed... not the standard DR4/CL4 trans

just an update on the ecentric breakage:: we had the trans apart to the point to change out the broken ecentric ,,after the second breakage total tear down was induced and the third gear bushing was destroyed dean cook found ,replaced third gear and three four shift syncros,,going down the track at this point gmonde

One year later in valdosta we had the same thing happen, this time when we looked closer it looked like a casting problem. It snapped the arm off smooth with the side of the trans. The shifting linkage was dragging on the ground. We replaced the arm and have gone on with things. That has been several years and many runs ago. We to have a long shifter on it. I hope it was just a freak thing that happened to you. Good luck.

This is exactly what happened to me yesterday, do you believe it was a casting problem?

Bobby, when you nave it apart, make sure that the shift fork didn't bend. It is something the happens mainly with the billet 3-4 fork. Also, on tnat fork, look at the machined groove that the arm goes in. If it has a dent in in, you will have an impossible time getting the shifter adjusted properly. Scott at Jerico says these can be repaired by welding it up and re machining the groove.
I had a couple that had done this after many years of service. It was impossible to get the correct gear engagement. It would be too deep in one dog and barely catching the other.

Bobby, in our case yes it was a casting problem. You could see the impurity in the casting at point of failure. We called Jerico and told them what we saw. They were curious and we sent them the parts back for them to see. They said at the time they believed that it was a "batch" that could have been bad. We run a three speed (265ci). So we do our burnout in 2nd gear so to break the 3/4 arm was do to stress during the run not during our burn out. There is a definate problem in this area. We use the 1-2-4 gears. We also had the clutch very soft no counterweights. I am sure that a clutchless trans would be different, due to the design of the sliders. I think what Joe said is correct but in ours it had so little runs it was different.
