Issues with the poly tranny mounts?

On a side note, did you buy the poly boots off me?

on a few that i have installed the stud is not seated in the poly very well, so when you apply moderate pressure to install the mount to the transmission cross member, the stud rotates inside the polyurethane. if i were building them i would weld the stud onto a rod the length of the poly.

Yes

This is the kind of thing you can ask in an e-mail… I doubt anyone but me would know anyway…

When the version number on any part I make gets incremented, it means it went through a revision of some kind (big or small) and needed some sort of differentiation from the previous parts (mostly so I can keep track of them better).

As far as failures, I have had 4 total out of some 90+ sold. Those failed were all from the very first batch. Some of the other very early versions had manufacturing issues leading to a less than ideal bond to the embedded bolts. Some also had incorrect bolt lengths, the list goes on. I have and will continue to replace those few if they fail. As I changed the spec for the newer version (adding a larger washer welded to the bolt, as well as specifying the depth of the bolt head and washer in order to keep the urethane under compression (which was called out on the original drawing but never verified until recently), the most recent batch was actually the 3rd "remake" of the batch until they could build them 100% to my new spec, hence the post about it on the website. The QC issues I speak of there are new… they were very apparent when I received the orders CLEARLY not built to spec. In the future these problems won't happen.

In the future I would like to have a page on each product linking to the instructions, revision history, and common failure modes. Like all production parts, revisions will be made as time goes on; generally in the past I have simply kept them to myself.

Um, :-? . Who is supposed to be getting or sending a PM? If it was from 1artworkz, I haven't got one yet.


As for my first post, I was just curious. I didn't mean to sound like I was bashing your product. I was just wanting to know if I should be aware of something or be on the lookout for a particular problem with my or any poly trans mount.

I will continue to buy your products as they come out. 8)

My bad. I PM'd a suggestion to Jason about the studs. I do not make the trans. mount.

Ball Joint Dust Boots are being replaced, no charge.
Jason gave me a list including email address of all those that purchased them for him.
Using the email list I sent out a notice that I was replacing them with a newer version
that has a metal ring in the seat that prevents the boot from lifting off and exposing the
ball joint.

For those that ordered red ones and have responded to my email message, I sent your
replacements out today via 2 day Priority.

Those that ordered Black will receive theres the end of next week.

This is a list (Whitlow, Jenkins, Coleman, Gardner, Poll) of people that have not replied to
my email. They will be getting a the replacement notice by US Postal Service.

I'm digging this up again because this issue almost delayed the release of my car on the first test drive after my build was complete. The gear stick was slopping around all over the place between shifts; got it back on the hoist and saw this.



The car hadn't even been driven. This mount was just installed and sat there for about 3 years. What's the story on these now? Is this a dead and gone part or what? I'd love my free one! lol My engineer buddy seems to think because there are no crush tube inserts for the bolts is why this happened and perhaps inferior polyurethane.

Responsetype makes a trans mount. better than the one you have pictured.

Wow, a vendor who gets his customers to do his R&D.

I'm just glad we found it driving around the block on the test drive and not launching hard at 6,000rpm! lol
