Just tried to replace the 3 nylon bushings on the '96 headlight motor and found them too big. I called ZIP and fellow acknowledged problem and said the correct sizes just came in last week. Doesn't really do any good at this time but maybe next week I can get the car put back together.

 

Yes there was a issue, you must have got some that were shipped out at least a month ago. I have not been shipping any since I found the problem. The issue was with a new batch that came in and they were .002" over sized. Well when just one is like that it is not a big deal but trying to install 3 of them like this is not going to be easy. With that said the new ones are in and they have been shipping. I can't do anything about what you have now except to replace them and the ones we have now are fine. I have already installed a set. With that being said they are not supposed to fall in place and for some reason it is believed that is how they go in. If they fell in place then your headlight would vibrated as your drive down the road. The bushings are supposed to a slight press fit to them. If he did not send new ones to replace what you had, please call us tomorrow and we will replace them for you. However there is no need to worry about what we have now, all the wrong size bushings were disposed of.

I am glad you quit shipping them. I just wish you had given those of us that had possibly gotten the bad ones a heads up on the problem. Actually, there may be others that haven't gotten around to putting them in yet and perhaps you might get in touch with them, too.

 

Wrong, the factory bushings are not press fit.

 

Sir, you are mistaken on that. I have a set of original ones that are in perfect condition that I used to make mine off of. If the bushings did not have a press fit, then the headlight would shake as you are going down the road. Now when I say press fit, you do not need to use a press to install them, you should be able to lightly tap the aluminum drive into the plastic gear.

As soon as I found out about it we stopped shipping them. Some headlight motors they went in just fine with a little bit more force, the aluminum drive also has some tolerance to it and this could make them easier or impossible depending on what end that tolerance was at. I did have a customer send me his motor and the problem with his motor was the aluminum drive was corroded, so once it was cleaned up the old bushing fit. Bottom line is they were too big by .002 thousandths. and now they are were they are supposed to be. What I found out was that the Swiss screw machine that normally makes these for us was down and another machine was used, that machine allowed the rod that was too big as it was shipped from the manufacture to be run. The rods are now custom ground for us so they are exact to the original GM bushing, the difference is the delrin will not break apart like the original ones did.

Wrong again. Sounds like you don't even know the difference between headlight bushings and the plastic gear.

 

hmm, i had ordered my bushings about 4 or 5 months ago, and just got them 4 or 5 weeks ago, question is if i got the good ones or the bad ones.

 

I would think it's just best to make a point and get on with life. I also would think that it's never a good idea to get into an argument with a paying sponsor and try to demean him. Mistakes do happen......all the time. It's so much a part of our daily lives that everyone should be used to it.

I'm certain that Zip's intent was NOT to sell a bunch of bad parts and hurt their good reputation. It was simply an error on the part of the machinist and they're making good on it. I don't see that as a problem.

 

You have a set that I bought to hold us over from another vendor until the ones I make were done. The ones you have are fine, but if you would rather have ours, then I can send you a set and N/C. Just give me a call my ext is 256.

Don't even know how to respond to this. I make the bushing, do you really think I don't know the difference between the gear and the bushing, seriously.

I bought from zip, a slight press ft, work perfect, gunny says it best, this being the 'tech' section, not the whine or trash section, there's to much of this peanut gallery b.s. in tech. its not off topic or even general . tech should be only tech, not personal opinion or scratch and whine. BTW the original poster with his 'beware' after zip fixed the issue with him was lame also, as long as we're not posting tech, it would be nice if you 'gurly men' would 'MAN UP'
