Anyone have a shift finger for Jerico?

tony5022 · 11-03-2013, 08:43 PM

Hey Bobby,
I broke two in 6 runs at Kearney a couple weeks ago. Scott from Jerico told me that I had to have a bronze bushing or a bushing machined to hold the finger tight again or will keep breaking. I wont be able to test until next year but that is the plan for me right now.

What parts are you guys braking? Shift fork? Shift finger that actuates the fork? Just curious maybe I should get one of these for the trailer for a spare.

what is this bronze bushing nonsense?

I also have had problems with Jerico shift fingers. Just has you experienced the crack starts at flat area and metal has a real grainy look(casting). I still have one of their early units and I never broke one in that tranny but have broken two in new unit even with a stop on shifter. Several other jerico users have experienced same problem. There is a quality control isssue.

The shift finger, it is what the shift arm straddles on the outside of the case. It is threaded on the outside and it goes from the outside of the case, through the case, and activates the shift fork. I seem to break the 3-4 finger alot. This finger has the most force on it because of the length of the shifter multiplied by the length of the lever (3-4 lever being the longest) must be the most torque on it. They never suggested a bronze bushing to me, they just said to use the clutch to shift.. sure thing buddy.. I miss my nash (three years of trying to break that thing and I couldn't).

My son (David) broke one 3-4 going to 4th in the semi's at the Door Slammers. After looking at our fatiqued finger, seems to me it needs a fillet at the base of the thread where Jerico milled it nice and square (no fillet). Everyone knows that a square cut creates a stress riser. I never broke one but I used the clutch pedal, my son does not.
Jerico, probably not change their process, but maybe the next guy can suggest it being looked into. Of course the shift lever will have to be chamfered to accommodate the fillet. As far as the bronze bushing, my case it real tight almost can't turn the new one once it's installed.

Bobby, If you make your own, you may want to consider this also. You may have customers.

Bobby are you going to make billet ones? Are you making any extra? Knock on wood that is the part I haven't broke in the trans yet. Been a rough year on my Jericos. I broke the face plated dogs in both of my trans this year. Which took out nearly every gear in the trans. Then Jerico tells me oh buy the way you should put a shifter stop on them and you won't have that problem anymore.

I have the part to three different machinists who are taking very long to get back to me. Now my original who does most of my work who said he would do it but would take him a while, I am going back to him. I think he told me 4340 steel was the way to go. I have been running shifter stops this whole time and it hasn't fixed my problem. I am going to have spares made for emergencies so contact me if you want me to make extras.

I think that their might be a market for some made out of good quality steel?
