help need a flywheel

[roadking]

Herd a funny knocking noise, found it ,were can i get a new one?

Most auto parts should have it available. I believe it's DORMAN Part # 04606, Pioneer automotive part #FRA533, if you want to go with a stock replacement.

Upfront, I know almost nothing about A/T's and such, BUT that center hub crack to me needs a little bit more info. Any history of ANY trans R&R on this truck? In the clutch world, this is an alignment problem. It caused flexing and flexed the flex plate until failure. Condition of torque converter pump hub and front seal, OK or torn up?



Good luck.

Not that un common with the autos and heavy towing or high miles. Of course the aftermarket has some heavy duty replacements-Billet,laminated etc.

Strange... I ran that number and it came up on Orielly's website, and on Rockauto.com..... Personally, I wouldn't replace it with a stock one, anyway, as it will eventually do the same thing, again. Blumenthal's offers a billet one I've used before, but my experience is limited. TDR member Cerebrusiam would be a good person to PM, if he's not too busy. I believe these are the same bolt pattern 91 and up. If you can find a good one from a donor truck, any year of the 12v should work.....



GCroyle, I know only a little bit more than you about the auto trannies, but that is a common failure, especially on the P-pumped 12v. The flexplate flexes, and it eventually just gives it up. The torque hammer is horrible on these things, especially in the later trucks with lockup TQConvertors. I would call it a design flaw... . You are certainly correct when saying the torque convertor, pump seal, and casing all need to be inspected before re-installing.



DTT makes a resonably priced billet flexplate, as does several other manufacturers, such as BD, TST, and Gorend.



A quick internet search shows many options, but these guys appear to have a stock replacement that looks just like the factory... . http://www.seauto.com/Flex_Plates-CUMMINS_FLEXPLATE_FITS_87-2007_5.9L_CUMMINS.html

HH and Bob,



Thanks for the info on occourences.



M/T's with separate bell housings, like the NV4500 its real easy to inspect and correct bellhousing run-out, can't do it on A/T's obviously the same way. And I second my lack of exposure to A/T's but inspecting the dowel sleeves and matching dowel sleeve holes couldn't hurt. One time I saw a Front Wheel Drive A/T core at my local parts store, one of the dowel sleeves was still stuck in the case. And I personally ALMOST pinched a wire on a Tacoma R&R, caught it just as trans came into position, but it was ready to get pinched and cause a problem. Either of these scenarios could tear stuff up bigtime.



My head, back and hands still ache a bit, just did an installation marathon on 3 vehicles for training videos, head still spinning.



To the OP, good luck.

are all auto flex plates the same for our trucks,89-2012 everything says 89-93 94-02 03-12 a freind said that 94 up had the lock converter,cause all the sites i've been check'en don't go back to 92,they all start at 94 and up?

 

[roadking]

my engine & transmission are out of a 92.

 

[Simplysmn]

see here it says they are all the same 89-2007. 5 ?

 

[cerberusiam]

They should all be the same. PATC has the 4 mil plates at a decent price also. Gives a little more beef on the flywheel.

Geee, I think I know them...

The old Mopar/ Direct Connection "speed bibles" told you how to check for alignment. The manual is done just as Gary said. But the automatic is similar too. The snag is that you have to gut the case so you can work "through" it.
Yhea Walt, rest up for the install, gotta make sure everything lines up right, the dowels are there... Years ago I could have helped ya... .

 

[roadking]

yup ... ... ... .

I just went and searched to see what PATC stood for... . I've heard of these guys, but had no idea they had that many parts... . I'll be on that site for a while... ... :--) OH, and thanks... .

 

[mysteryman]

You are correct. It normally is an alignment problem. . But not always. The way you check an auto's alignment is to

remove the trans. Gut the case of all its parts. Bolt case back on engine. Attach a dial indicator to the crank . Run the plunger on the front pump bore. Rotate the crank and watch the indicator needle. The amount it moves is how far off center the trans is from the center line of the crank. Look up my other posts on how to correct the alignment

of a manual transmissions bell housing to correct the problem. This info can also be found in any factory Dodge repair manual in the clutch section. As for a used flywheel... . I should have a stock used one if you want it. give me a call if interested... ///MM
