Rock Auto (CPS Synchro - Dorman parts failure)

[bidness]

I ordered a camshaft synchronizer last Friday 01/04.
Got a call late in the day from Rock Auto that the part was on back order, Spoke with them today checking on the status, saying that the order has been cancelled because Rock Auto may not be able to get part anymore. Any ideas as to where to order from besides Ford?
Thanks

advance auto
napa
car quest
bumper to bumper
o'rellys

Stop.
I have a new one coming in the next 5 days with the alignment tool. I just want to take a peek at it and see if there is anything I can do to make them better (cryo treatment or dry film lubricant), then it's yours at cost + S/H.

If you need it now, then see above...

Hello BOSS, My CEL went off a few weeks ago, a friend checked it and it read " Crank position sensor".
I just replaced the synchronizer & sensor back in May. In May no CEL came on, but based on info from threads @ RPS I replaced both. The one I have now has about 25000 miles on it. My friend removed the the synchronizer and did a visual inspection and checked moving parts and told me things looked good. He did go further and checked all connections, erased the code. things are OK for now. I wanted to replace it as a preventive measure.
As of today I have 169000 on the truck, commuting 65 miles a day does that. I change the oil ( Mobil 1)between 3-6k miles, transmission has been changed 3 time since(04) I 've owned the truck, haven't had any problems. What kind of mileage should I be able to get out of this. Should I be on the market for a newer ranger?
I'm interested in the synchro. What's the cost?

Thanks
Don

cryo treatment

What is that?

[bluedevil3758]

What is that?

when they freeze the metal to make it stronger, or something like that, i know they do it to diesel blocks

[radranger]

When I was looking at replacing it, I checked with NAPA and all those places, and none of them had it, seems to be a pretty specific part.

[usmc7579]

The Dorman part number is 689-107 and it comes with the alignment tool. Our AutoValue parts store has one available.
He checked the warehouse and said they have gone national backorder. Their price is $53.99.

[BOSS 3.0]

Not suprized, the rate of failure is pretty high and with many of those CMP equipped engines are now well past the 100,000 mile make, supplies are getting thin. That's why I'm looking for a "cure" now...

[MR 130]

its call a distubutor ha ha ha

What part of the CPS/CMP is going bad. Just checking to see if it is the same part or different parts that are breaking on the CPS. My gear(the part against the cam) was the part that went bad (stripped). Also the washer (spacer) above the gear was gone.(chewed up) The rest of my BAD CPS looked good. Are those the only parts going bad on these CPS. BTW my truck is an '01 with a 3.0L.

[BOSS 3.0]

It is my understanding that the gear that engages the cam is loosing teeth, or shattering. I think it is a end play issue (or lack there of) myself...

[mrmrrck]

here is a picture of my bad Cam Sync. As you can see the gear is stripped and the bushing/ washer just above the gear is missing/ gone. This one is the Dorman. Hope this help.

[BOSS 3.0]

How many miles on that Dorman?

[laser3kw]

That looks a bit better than the stock unit that came out of my deceased 3.0. I checked the end play and radial T.I.R. - neither was very much. I still think it has a lot to do with the torque required to drive the oil pump.

Consider this: You can set up a gear set with a bad miss match and run it all day in oil with no problems. BUT apply a load to that set up and it will eat itself to death in a short order. Another point to consider is, if you look at the TSB's for our motors, you will notice there are ALOT of them concerning oil viscosity. Another point, it is pretty much common knowledge that certain oil filters seem to be to restrictive and can damage the motor. Restriction = harder work for the oil pump.

After I put a motor in my truck, I started out with 10w30 Mobil 1 and a off the shelf filter. I kept seeing the oil pressure gauge flicker, jump and read differnetly (high one day lower the next). I switched to 5w20 Mobile 1 and a motocraft filter and haven't seen anything since.

Just my experiance fwiw

[BOSS 3.0]

...hence the TSB's for 5W20 oil, and quality filters have always been an issue. Makes sense!

But, why is this an issue with just the EEC-V version? This doesn't happen with the Distributor version, or maybe it does - I've never used crap filters or heavy oil, nothing ever more than 10W30, usually 5W20 and Mobil1 filters.

The load issue makes perfect sense; as load increases the pressure on the gears, being a helical gear, this load forces the shaft UP, against the thrust washer. So:

Is the gear thrust washer face too rough and eating the thrust washer?
Is the thrust washer itself not made of a strong enough material?
Is there a new oil pump that has an increased loading on the new engines? (old engines had a "low oil pressure light" TSB issue, but that was due to the "dummy guage" switch).

[laser3kw]

I'll look at the trust washer more closely. I don't recall it's condition. I was just amazed at how bad the gear was!
I kinda wonder, when they switched from distributor to CPS, they thought that they could cheapen the gear up. Maybe they went to a different material or maybe the hardness went down or something. From what I know of Fords in general, the always have had questionable oil systems. They always just seemed "adequate" or "marginal".
I have also seen on the chevy sites that they have had a similar problem. So could it be a V6 harmonic problem? Traveling through the cam shaft and meeting the impulse reaction of the oil pump and causing a ratchet action or a frequency buzz?

Just some thinking out load

[mrmrrck]

Boss, That part had only 25k on it when it went bad. The original CPS washer/bushing was alot thicker than the one on the Dorman if that makes a difference. As a matter of fact it was really, really thin. Is there any way we could put a bearing there instead of a washer? Also I still haven't found out yet,if the gear is the same as the one on the distributors. Another question; is there anyway we can put more oil on the spot where the gear and the camshaft mesh together?

[rileysranger]

Im new here and im not 100% sure if the 3.0 motors are the same, but i have had that gear wear out on a few taurus's at work. They were distributor systems.

[BOSS 3.0]

Yes, the same 3.0L Vulcan Engine (12 valve - not the 24 valve) was used from '86 and up in the Taurus, Tempo, Topaz, Sable, Probe and others. Pretty sure they would have the same issues...

[Artless]

The Dorman part is cheap for a reason.($30-40 on ebay in many cases) It's interesting to me that people(including me) say don't go cheap on this or that, but when it comes to a part that will almost definitely seize an engine when it fails, it is OK to buy cheap. Buy Motorcraft. I bought one of those Dorman parts off ebay and I was not impressed because ford said they would not warranty any aftermarket replacement part they installed, so it was resold.
As for the gear failing because it has to turn the oil pump makes since to me. I'm surprised it is able to take start after start in 0 to nearly -20° weather. My engine is pretty noisy when started at those temps in the morning. Even with Mobil 1 5w30, I don't want to know what regular oil would sound like...

EDIT: Anyone looking for the motorcraft part on rockauto's website it is within the ignition->camshaft position sensor category.F8DZ12A362AA is the part for most applications, and it is a synchronizer, not a CPSensor as listed (same part number on my ford dealer invoice, but for about half the cost at $76.). Make sure it fits yours by selecting your truck and going to the said category. I do not know why they do not list it in the engine->camshaft synchronizer category like the Dorman sync.

[mrmrrck]

Does anyone know if our 4.0l brothers are having this problem?

[Artless]

bidness, I just realized you are the one I sold that part too! Sorry it was crap. Check out this thread which shows just how crappy they are http://www.taurusclub.com/forum/inde...pic=53152&st=0

Other than the motorcraft I linked to in my previous post above I found a NEW Cardone select synchronizer assembly in the ignition-> crank angle sensor category for 68 bucks.(looks like it comes with the new sensor as well when looking at the picture in the "more info" link.) There are also remanufactured ones for less on that page as well but have that core charge.

I would buy the new cardone or the motorcraft. Unsure if the motorcraft comes with the sensor, so the cardone might be a better deal.

[MR 130]

boss would you recomend a even thinner oil than 5W20 or would this be fine?

[BOSS 3.0]

5w20...

[MR 130]

humm its not that thin
my car runs 0w-40

[Zeptoplix]

Hey, I saw that someone linked your thread to the dorman thread on our forum, so I figure maybe you would be interested in reading ours. I haven't really read about gears stripping, but here, you can read for yourself.

PAGE 3 of the above link has side by side pics of Dorman vs Motorcraft. Nice work guys. They even have a Dorman rep involved.

[BOSS 3.0]

It also tells you how to make a claim against Dorman. That's where having a shop install it pays off...
