1971 Plymouth Valiant fly wheel

does anybody know what the other fly wheelsa can be used on an 1971
plymouth Valiant with an 225ci(3.71L) engine with an 904G trans? Mine is
bare and needs to be replaced.

any thoughts welcomed.

 

Any slant 6 flexplate from 1968 through 1988 except those used with the 727
and 12" torque converter.

Your flexplate is bare?

If it has a 904 transmission, it wouldn't have a flywheel.

The torque convertor contains the ring gear for the starter, it
mates to the crankshaft via the flexplate.

 

Bare in spots or is that teeth in spots.. It looked kinda iffy when i put
the starter in about 1.5 years ago. it is our back up car. my primary car is
an 1991 plymouth acclaim and it is down right now also(near dead engine).

 

Does that mean that I need to replace the torque converter?

 

Neil,
By "bare", do you mean it is missing teeth for the starter to engage? If
so, that gear *can* be replaced but it's often not done because the process
is a bit tedious, and a replacement converter can be had relatively
inexpensively. If you wish to replace the converter, I recommend you steer
clear of used converters -- I recommend going with a rebuilt unit.

As others have pointed out, your Valiant with automatic transmission
hasn't got a flywheel, per se. It's got a torque converter, and if the
ring gear teeth are worn or broken, you will need either a replacement
ring gear or a replacement torque converter. I agree with the poster who
suggested a rebuilt torque converter. Be advised that while *most* '71
Slant-6 automatic cars got the regular Chrysler gear reduction starter, a
few of them got the direct-drive starter instead. These two starters use
different ring gears (perhaps a cause of your currently-chewed ring
gear?), and many catalogues do not list the torque converter for the
direct-drive starter. The fix here would be to talk with the converter
rebuilder -- these are usually done locally. The ring gear needed for use
with the direct-drive starter is that specified for use on all 1960-1961
slant-6/auto applications.

I'm not the original poster...

 

Most likely.
The starter ring gear is usually welded on, so replacement would
involve cutting the welds and then welding a new ring gear on (if
you can even find one) and then hoping it runs true.

Manual transmission flywheels had/have field replaceable ring
gears although replacement involves "sweating" the new gear onto
the flywheel, IOWs, you'd need a method to uniformly heat the
entire ringe gear.

 

All of the other posters are correct, mostly. The cheap, easy fix is to go
to the junkyard and grab another convertor for $10-$20... slant sixes where
a dime a dozen once upon a time. (go to the little out-of-the way junk
yards... their easier to deal with). Look around and out in the farmers
feilds on your way, you might just get a complete, running 'parts' car for
free just for towing it away. Don't be shy, walk right up and knock on the
door...smile, be polite, and be respectful.... watch out for the dog).

ooh yea.... look for valiants, darts, dusters, ect... a dime-a-dozen engine,
a good one too.... I'm probably the only guy on the planet who was ever able
to 'beat' one to death. A two-barrel carbs will fit on the one-barrel intake
too....)

 

Interchange is '68 to '77 passenger car with slant-6 or 318 V8 engine and
904 (standard duty) automatic transmission.

Won't, at least not without one of those dumb 2bbl-to-1bbl "adaptors".
2bbl intakes for the \6 are readily available, however.

 

Oops!

 

Yes it will....turn the 2 barrel sideway.

 

Ooh...I forgot to add that you can also swap in a 318/340 for a slant six
by turning the right slant six motor mount around. The engine will sit
slightly tilted but it works. The proper way it to use a V-8 K-Frame but if
you don't have one laying around.... turn the mount. My junkyard owning
friend did that with a 340/Dart combo..... daily driver raced at the local
1/8 strip every weekend for 2 years.... great little ride.

 

*Won't*. The 2bbl has a 4-bolt, rectangular mount. The 1bbl has a 2-bolt,
oval mount.

You're on glue.

 

This is one of the major reasons it's so hard to find good used old cars
-- idiots like "Pax" have hacked them.

 

yeash i saw guy do that once with a log chain as a motor mount. engines and
trans sitting at a 30 degree angle. wondered why he kept breaking trans
mounts........

 

Not as bad as the old Fenner 2X4s....

 

never saw those........i'll have to ask him next time im in vegas!!

the guy i was thinking about was a loser down at frank dunns salvage
