Anyone have a shift finger for Jerico?
 

If anyone is headed to Hagerstown tomorrow and has one I'd be very grateful. Thanks.

Re: Anyone have a shift finger for Jerico?
 

Can you be a little more specific? I'm not familiar with 'finger'.

The piece going through the case that the shift linkage bolts to. I sheared the 3-4.

Re: Anyone have a shift finger for Jerico?
 

Ok, I personally do not have that piece. I do have a friend who may. I will check in the morning. I don't remember ever having broken one of those pieces.

Ok thanks for trying Andy. Much appreciated.

Re: Anyone have a shift finger for Jerico?
 

I broke the same 3-4 shift finger again yesterday during second round. After this happened at the end of last year we ordered a couple and replaced them, this one only lasted 30 runs this year. Anyone else having this problem?

Re: Anyone have a shift finger for Jerico?
 

I have not broken that, but have had a few friends that have. I wonder. Maybe check with Scott at Jerico and see if the heat treat or a engineering change ever took place.
They have a bunch of stress on them, especially those that use the taller shift handle and a lot of clutch.

Re: Anyone have a shift finger for Jerico?
 

Only racers I've ever seen break them were using shifters without stops or the stops not correctly set. Have a freind with 4 speed jerico with hundreds of runs never broke it.

Re: Anyone have a shift finger for Jerico?
 

I seem to remember a thread some months ago about a batch that were more prone to breakage. Scott at Jerico is the one to talk with. Also be sure that the shifter stops are carefully adjusted to lessen force on the finger and the fork.

Re: Anyone have a shift finger for Jerico?
 

Bobby I'll look in my spare parts. I've never broken one. Do you have a v gate shifter?

Re: Anyone have a shift finger for Jerico?
 

Bobby I have one call me 512-517-8235. Ed

Re: Anyone have a shift finger for Jerico?
 

I have 2 Jerico DR4s with Long V Gate shifters, and neither shifter has any stops.I`ve had 1 trans 12 years, the other about 5 years, never broke that piece.

Re: Anyone have a shift finger for Jerico?
 

I run stops and I checked them today, they never moved and we set them up on the bench to make sure they were perfect. This piece seems to break coming out of third and going into fourth so I don't think the stop has anything to do with it. I would think there is more stress coming out of gear then going into the next gear.

Re: Anyone have a shift finger for Jerico?
 

Hey Bobby, When you asked me about the shift finger at Maple Grove on Sunday and I said I never had that happen, I must have jinxed myself. In the semi's I had no 4th gear(went red anyway) but it seemed to stay in 3rd. Is that what happens when that thing fails? It tried it on the return road and it went into 4th. Sound familiar? Thanks, Bill.

Re: Anyone have a shift finger for Jerico?
 

Hi Bill, sorry to hear. No that is not what happens with mine, it shears the piece that the shift arm is bolted to so the actual shift rod falls down and drags on the ground, the shifter then just floats back and forth in the 3-4 gate and nothing can happen because the rod is no longer attached to the trans anymore. Your issue sounds like the clutch could be getting hot in the late rounds causing it to be tougher to shift out of third. Or the rod was bound under heavy load, that used to happen with my old trans and on the return road would be fine. It would happen in later rounds when the clutch was gripping hard.

Re: Anyone have a shift finger for Jerico?
 

Bobby, Thanks for your response. I didn't realize that part (I would call it the 3-4 shift fork) was breaking completely off. I assumed that it was doing something stupid inside like cracking which could be intermittant. I guess I'll have to pull it apart and look. Nothing worse than something that's only half broke. Can't really see how the clutch could cause this problem but anything is possible. Anybody got any ideas? When I find the problem I'll let you know. Bill Taylor Stk 1005.

Re: Anyone have a shift finger for Jerico?
 

Jerico doesn't ship again until Monday so if anyone has these fingers they would like to sell please let me know.

Re: Anyone have a shift finger for Jerico?
 

Bobby, I assume you saw Ed Carpenters post!? I have your shop number. When is a good time to call? Thanks, Bill.

Re: Anyone have a shift finger for Jerico?
 

Yes thanks Bill, Ed shipped me one so big thanks to Ed.

Re: Anyone have a shift finger for Jerico?
 

Mondays a holiday so Jericho don't ship til Tuesday. Just in the interest of accuracy

Re: Anyone have a shift finger for Jerico?
 

I've taken all the shift fingers I currently have, as well as the brand new one I just received from Jerico, and my machinist and I did two dye penetrant tests on them and they ALL have cracks, even the brand new one. Evidence of cracks at the bottom base and 1mm up in the flat (where mine keep breaking). These pieces are not being made right from the factory. My machinist believes the heat treat process is not being performed correctly. I am going to have some made out of 4340 steel rather than 8620 and they will hopefully never break again.

Re: Anyone have a shift finger for Jerico?
 

Bobby, when my father bought his Jerico 3speed (for a 265 chevy) several years ago. He broke the 3-4 arm off the trans with about 15 runs on it. We thought it was a freak think, this happened at a points race. He bought 2 more arms so he had a spare. Broke it again with about another 10 runs, at a points race again. So we replaced it and went on. I looked at both broken arms and you could see the imperfection in the castings at the point of failure. We spoke with Jerico and at the time he was unaware of it but he wanted to see them. So we sent them back to him. That was that. We thought we were the only ones to have this problem? Guess not. Sorry it is happening to you. Hang in there.

Re: Anyone have a shift finger for Jerico?
 

Damn I broke this 3-4 shift finger for the third time in a year. 30 runs on the last one and now this one was on the 17th run.

Re: Anyone have a shift finger for Jerico?
 

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.

Re: Anyone have a shift finger for Jerico?
 

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.

Re: Anyone have a shift finger for Jerico?
 

what is this bronze bushing nonsense?

Re: Anyone have a shift finger for Jerico?
 

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.

Re: Anyone have a shift finger for Jerico?
 

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).

Jerico finger update needed
 

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.

Re: Anyone have a shift finger for Jerico?
 

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.

Re: Anyone have a shift finger for Jerico?
 

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.

Re: Anyone have a shift finger for Jerico?
 

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

Re: Anyone have a shift finger for Jerico?
 

Has anyone tried to get a billet shift lever for a toploader trans? Years ago Libertys used to make billet shift levers for the toploader trans and unless Jerico has changed the design, that toploader forks and shift levers would work. Years ago, Jerry used to build a Toploader cased Jerico before the Stock Guys could use an Aluminum or Mag cased Jerico. I pushed the Cluster shaft into my early narrow toothed Jerico and sent the case to Jerico to get a steel bushing installed , in the meantime I purchased a cast iron Toploader case from Jerico, to use, while they had my other case. I split the first cast iron case and modified a toploader case by reaming out the cluster shaft hole and adding the extra detent at the back of the case. The cast iron case also needed a spacer between the throwout bearing collar and the case. I ran the modified toploader cases for 3 or 4 years while I waited to get my original case back. The original toploader shift levers had an o-ring groove that was the weak point. Before billet shift levers were available, the o-ring groove was welded up and ground smooth. All the internals of the narrow tooth Jerico fit into the modified toploader case so there is a good chance someone may make a billet shift lever for a toploader that will work.

Re: Anyone have a shift finger for Jerico?
 

I finally found a machinist to make these out of Billet steel with a proper heat treat.

Re: Anyone have a shift finger for Jerico?
 

I will check in the morning.http://www.bettecets.com/4.jpg

Re: Anyone have a shift finger for Jerico?
 

I just ran across this post. I have broken 3 shift fingers
in the past year, all 3-4.

If someone is making better quality pieces I would like to get a name/address/phone number.

Thanks in advance,
Gerry

Re: Anyone have a shift finger for Jerico?
 

Why is it that Jerico cannot make parts for they're transmissions anymore?
I'm seeing quite a few Jerico's for sale?
Whats UP?
What happened to the Quality?
Craftsmanship?
Material?

Re: Anyone have a shift finger for Jerico?
 

I have broken the 3-4 finger twice now this year,i believe the first one was original,the second one lasted 6 passes.I have had a DR4 for 5 seasons,always use the clutch,also has a LONG verticle shifter no stops.The first one was a clean break,looked like it was sheared off clean and straight,the second is fractured,very jagged! I talked to Jerico last Wednesday[July 16 2014],their responce was they had no idea of an issue as nobody has reported an issue?!!! I have read through all four pages and it looks like they will break with or without clutch use and with or without shifter stops.Has anyone come up with a reason or a solution? I just drove to a N/SS race 1500 miles away only to break Sunday morning,SUCKS!! ROY.

Re: Anyone have a shift finger for Jerico?
 

I am sorry to hear this Roy, I and many others share your frustration. I have had them break in the middle of money rounds where my opponent was broken and we both had to limp to the stripe (he won)!

But the good news is I finally found a machinist to make these for us out of 4150 chrome moly billet and I just got two of them yesterday to test for fit. They are mighty pretty pieces.. Will keep everyone updated.
