GMpartsdirect Equivalent

Re: GMpartsdirect Equivalent

To Duke and all the other non believers.

The man is here and here are your details you can believe it or not, but it is done every day.

The TRW I work at makes steering gears for Chrysler. Other TRW factories make over 10,00 other components.

For example we make a hydrolic valve in which every one is tested to classify what group they go in. Which is A B or C then scrap. Class A are used in the steering gears that go to Chrysler, B goes to the service replacement to Chrysler like for warranty work and repair. C goes to all the rest of the aftermaket suppliers. Scrap goes to recycling bin.

As the line goes on after the valves are classified A B C or scrap, every steering gear is inspected for any flaws, even if it is just a date tag peeled up, if any flaws are found they are tore down and started over. but keep in mind the gears have already been determined where they are going.

So there is all the time you don't believe is spent, and that is the only way to get quality. There a seconds in everything on the market.

All I was trying to do was help find a good valve. I don't think a Corvette engine should have a $ 7 seconds or thirds valve in it.

One last good story for you on aftermarket parts.

My other brother with the ASE certified garage and is a for at the moment a NAPA (but not for much longer) distributor put 4 fuel pumps in his pickup in less than 3 years. One was 6 hours away and had to have another mechanic put it in. He said that was the last straw an put a GM pump in it and has run for years with no humming noise like the Napa ones either.

So there you go, this is my last post on this subject. If you don't believe me that is your denial and I will stick to my original parts.

Good luck with your motor, I really hope it works for you. I did check on the GM valves for you if you are interested let me know.

Re: GMpartsdirect Equivalent

Same company makes the fuel pumps for Delco and NAPA and has done so since Delphi spun that division off. Also makes the pumps for Carquest. They all have the AC part number stamped on the housing

...And now we see why Toyota is kicking our can. Instead of inspecting the quality into the product, how about learning to control the manufacturing process so that there is no such thing as A,B,C and "sCrap" quality? The Japanese learned this from Edward Deming 40 years ago.

Apologies, but I couldn't resist after reading today's headlines...

I could see where the described parts "grading" system could be used for some parts. Very rarely are the OEM specifications for a particular part set at an exact, specific number. Usually, there is a numerical range specified.

For example, let's take the case of a hypothetical power steering pump. Let's say the OEM specification for a NEW pump calls for an output pressure of 450-500 PSI. This range is set by the design engineers because the allowable specification range for the various components that make up the pump could result in a pump with components which meet all specifications producing pressures within the 450-500 psi range. In addition, the design engineers would also have determined that any output pressure within this range would provide for satisfactory operation of the power steering system of which the pump was designed as a part of.

Generally, of course, for a part like this it would be desirable to have a pump which produces pressure at the upper part of this range. However, any pump which operates WITHIN the range meets OEM specifications.

As the pumps are manufactured and tested, any pump which falls within the output pressure range would be deemed acceptable. Those deemed acceptable could be shipped randomly, as they come off the manufacturing line, to whatever customers the manufacturing source supplies. However, the manufacturer really would not be under any OBLIGATION to use such a random system. As an alternative, the manufacturer could set up a "grading" system in which pumps which generate, say 485-500 psi are graded "A", pumps which generate 470-485 psi are graded "B", pumps which generate 450-470 psi are graded "C", and pumps which generate less than 450 psi (i.e. below the OEM specifications) are considered scrap. The manufacturer would be free to distribute the graded pumps as it sees fit or in accordance with contractural obligations.

Keep in mind here that NONE of the pumps which meet the 450-500 psi output pressure range are junk----they all meet manufacturers specifications for a NEW, OEM pump.

David, I agree with what you're saying 100%,even the "best" tires go on new cars while the ones that didn't meet spec end up in tire stores. Bob

Re: GMpartsdirect Equivalent

Hey guys,

I just went online to order a set of valves from GMpartsdirect. They informed me that they no longer carry them. At least not the ones I want
.I learned of GMpartsdirect from this forum and have saved a fortune , so thanks !

So now my my question is where else might I aquire a set of 1966 GM valves at a less then GM price? $20-$23 apiece, That is the price Sckogins -Dickey is quoting. Do I even need to go GM on valves ,As nowadays they are most likely made in china anyway ?

The valves in question are: Intake Valve #3849814
Exhaust valve #3849818

Thanks ,

Jim,

An excellent source for finding old parts in dealer's inventories, is via www.partsvoice.com. You'll need to register to perform the search, but it's free. BTW: I ran your requested part numbers on that site and did receive some hits.

The Japanese were the first to embrace Deming in the fifties, but by the mid to late seventies Americans began listening because the Japanese clearly had better manufacturing control. The gap has been closed for about the last 15-20 years.

Keep in mind that the foreign transplants buy a lot of North American sourced parts from the big American-based parts suppliers that also supply GM, Ford, and Chrysler, and GM casts and machines the base Camry four-cylinder engine block!

The big difference is still vehicle assembly labor costs with the Big Three having an average $2000 disadvantage relative to the foreign transplants, and we've recently discussed the reasons for that gap.

Bob -

These days, OEM tire selection by vehicle manufacturers is a pretty exotic process, and tire manufacturer advance submissions for evaluation must meet a TPC (Tire Performance Criteria) specification, which focuses primarily on rolling resistance (for fuel economy); most retail (tire store) tires don't meet the TPC specs, and have slightly different materials and construction than OEM tires.

Jim,

I received your PM, but couldn't respond as it looks like your preferences don't allow PMs.

If you are still having difficulty with the partsvoice results, let me know. Keep in mind that you will need to search the General Motors category and do not limit your search to your local area.

Re: GMpartsdirect Equivalent

James,

Sorry about that. I didn't know I didn't allow PMs ?

Both suggestions are good ones and I will try them before I ask you for more help.

Well Jim started a wonderful thread, although I live outside USA I am all ears and my eyes are one meter diameter...

Thanks for the comments. Any conclussion regarding parts quality?

Re: NAPAonline cross reference?

In the end maybe eveyone will realize what I've found over the years. You can not go wrong with genuine GM parts, even though they are a little higher in price. Why is this so difficult for us to understand? The GM engineers designed them in the first place! (I know, it's too late now.)
