Finally got my Hurst shifter for my bday [img]style_emoticons/<#EMO_DIR#>/banana.gif[/img] [img]style_emoticons/<#EMO_DIR#>/banana.gif[/img]

Before I install it, I would like to know.

I read that one guy took part of an inner tube and made a gasket of sorts.

Some mentioned the bolts loosen up after a while?

Any suggestions would be helpful. [img]style_emoticons/<#EMO_DIR#>/worship.gif[/img]

Thanks

Did you put the offset piece to the pass side( old instructions) or the drivers side(new instructions)?
I made the gaskets and still have the vib issue [img]style_emoticons/<#EMO_DIR#>/banghead.gif[/img] , I have mine installed with the offset to the pass side and I am thinking of changing it to the drivers side, I thought I remember reading someone trying this and having all kinds of new issues [img]style_emoticons/<#EMO_DIR#>/dunno.gif[/img] I am also thinking of going back to the stock rear bushing...any thoughts?

OMG, all the threads posted here after March 13 are gone...Oh Well, here is the latest update, and I am sorry for thjose who have not been following, who are not going to understand!

UPDATE:Hi Jim,
My last mail to you:
"Hi Jim, I got the shifter and installed it last night, I wont be able to
test drive it until the weather clears, hopefully tomorrow.
The only mistake in the directions is on the size of the jam nut for the
ball...it is not 9/16, it is 15mm.
What king of grease are you coating the bushings with from the factory, they
have something on them. I used Valvoline synthetic car grease, is this OK?
I put it in exactly as instructed except for the front bushing, I did what
we had talked about, I put the shoulder of the sleeve against the tranny,
and for the other side I used a washer exactly the same O.D.and thickness as
the shoulder of the sleeve from the factory, tightened it down real good,
this should simulate the 2 shoulder flanges that you originally designed
this shifter for.There was a tiny bit of play in the new shifter you sent
me( spherical ball), maybe a 64th, my shifter that I took out had at least
triple of that. That difference maybe what happens as the shifter breaks
in.My vibration problems were not there initially, it came on as time went
by...many others have reported the same thing.
I will let you know my progress, just wanted to let you know where I am at."

So this is how it went:
1st install/ no isolator/ Hurst bushings...still had vibration at 3000 rpm
and at 5000 rpm, but the intensity was cut in 1/2 vs. the old shifter, the
shifting was also improved.
2nd install/ installed the isolator/ Hurst bushings/...much improved,
vibration at 3000 rpm is GONE, and the vibration at 5000-5500 is much less
intense for sure, much more livable for sure, also seems to lesson with
increased heat.
3rd install/ isolator still installed/ Hurst front bushing, stock rear
bushing/... same livable vibration at approx 5000 rpm, shifting is easier
and smoother.

I will leave it in the 3rd configuration for now, but I would say that the
2nd configuration would be just fine also.I would assume that the 2 pieces
of rubber will wear as time goes on and if the stick is removed for any
reason they should be replaced, they deform a lot when tightening down on
them and I am sure the serrations will rip them up considerably and the vibe
will return.I actually think they should be a little denser for durability
sake, also may have taken the vibration away completely, don't know.How can
I get replacements for these when the time comes? I would definitely like
to try out that other mod you were telling me about that you are in the
process of producing.This isolator is a Band-Aid fix at best!
There are a few people watching and waiting to see what happens with this
experiment that we did, they have the same problem as me, what do you want
to do about these people? I told them I would ask you when I was done, I did
not think you wanted to get barraged with calls so I never did post your #
on the forum, people asked me and I told them we would look at the whole
thing after we see my results... so it is your call as to how you want to
handle it.Let me know and I will post it.
It is amazing that some people had no vibration at all.
As for my recommendations, I would include either a special washer or a
replacement 2 piece bushing set with your kit for the front mount, also
change the instructions to read flipping the bushing around if you were to
stay with the 1 metal bushing configuration and supply a special washer for
underneath the bolt head to simulate the flange that is missing.I would also
put torque values on every fastener in the install. Lots of people were
confused on how tight to tighten everything, Put a warning to only put
locktight on sparingly near the plastic sleeves in the offset swivel and to
also put loctight or supply new nuts for the rear 2 nuts since the locking
feature is no good after the first install from the factory. Last but not
least, on the offset swivel nut in the middle, I did not use the factory nut
because it chews up the plastic sleeves, I used a nyloc and a washer( same
dia as the plastic sleeve) and only tightened it up to SNUG!
Jim, I want to thank you for the great customer service by YOU only, I think
the procedure Hurst uses for customer service stinks and it is to bad I had
to write a nasty letter to get the great job you did for me, but you said
you are working at resolving that so I am happy there to, I hope it happens,
there is nothing worse for the customer who is having problems with a
product to have further frustration by not being able to get anywhere with
the retailer, very, very aggravating, and not good for word of mouth
advertising all.
Jim, again thank you for the help, I do appreciate it, if I can be of any
other assistance do not hesitate to contact me. I would also be willing to
test out any new products you may have in development, especially a new
shifter.

Thanks for the update! I'll be installing my Hurst w/chrome stick next weekend. Got any pics of this washer and isolater installed?

So hear is the deal. He wants you to use the tech site as the pathway, also mention his name as part of your email concerning your problem...JIM PUSKAS. I am sure he will supply anybody with the isolator kits if they are having the vibration problems, also, he will supply a new shifter minus the ball and stick to anybody who has a spherical ball problem as I had( play up and down).
Wish you all good luck, it is such a pleasure to drive without that racket, I really never realized how much I hated it till it was gone.
