Check Egge.  www.egge.com

They list a new set of pistons for $203.  Better call first.

Hastings will provide a new set of rings for about $75

General Discussion / Re: Brake drums
« on: November 03, 2008, 10:56:16 PM »
I agree.

I had my brake drums turned - and did not have to remove the drums from the wood spoke wheels.  The brake shop enjoyed doing the work - they do not see many of those!  They also relined all the shoes and ground them to fit the drums.  Probably more than I needed to do, but I drive my car a lot.  The brakes work great.

Hastings has been making rings since before Plymouths were made.  You can order a brand new set for about $75.

The same brake pressure switch was used on many cars up through the early 1950s.  Should be able to find one at your local NAPA store.

Doug,

The cowl lights and trim on your 29U look great.  Are they original?  Is your car a delux model U?

General Discussion / Re: Where can I find a new pinion seal?
« on: November 03, 2008, 10:36:57 PM »
I also bought one from the Antique auto cellar.  These are new seals.  But be sure and measure the shaft diameter first, as some early 28Q and 29Us had odd sizes, as I found out.  Not a problem for Tom Hannaford though, he can provide them in any of the various sizes.  You may also need to sleeve you old spider shaft (where the seal rides).  Tom can provide those too.

Chet,

I talked with them a few years back and was told at that time that to rebuild one would be $2995! 

I had one many years ago that had a working accelerator pump, but it has since gummed up and have been unsuccessfull in clearing it out.  I will aggree, it does not seem to make any difference in the cars performance with out it!

Some parst are available for the 28-30 Chevrolets that will work on our Carter Carbs.  I obtained a new brass bowl for $36, bowl nut, and a few other parts to get one in running condition.

I agree a rebuilt Tillotson (or Marvel) is probably the way to go, and use a polished non-working Carter brass bowl type for show.  However, I do have a 28Q Carter Carb on my 29U  now that seems to work satisfactory.  New or rebuilt Tillotson or Marvel carbs are available at reasonable prices.

BTW - Some people do the same thing with the original AC spark plugs - they keep a show set that they put on only at a meet.  The original plugs were AC G-12s, but are hard to find and expensive (The Cherolets use them too).  However, AC G-14s were an authorized alternate (a hotter plug, good for stop and go city traffic), and are easier to come by.  Also, you can get reconditioned G-12 or G-14 plugs for much less.  They look just as good as NOS, and if only used for show, who cares if they are reconditioned.

For a good driving plug, I recommend the modern AC 87.  It is a hotter plug (like the original G-14) which reduces fouling and does very well for the kind of driving these cars usually experience today.  Other acceptable modern driving plugs are the AC 86 (no longer made), Autolite 386, Champion D16.

The 28Q Silver Dome used a 7/8-18 thread AC "A" or "AA" Spark Plug.  The higher compression Red Head Plymouth engines used an AC "Y" plug.  These will work on the Silver dome engine too.  I believe the Club judgeing rules accept any of them.  I am told a good modern plug is the Champion C7.

General Discussion / Re: Hand Cranking your Old Car.
« on: July 05, 2008, 06:30:22 PM »
Good luck!

The only time I use the hand crank is when adjusting the valves - it is very helpfull for that.  I would rather push start the car than risk braking an arm hand cranking it.

For a carb, it may take you a long time to find a working original.  In the meanwhile, you could probably use a Carter BB-1 Universal Updraft carb.  This would be easier to obtain.  This carb is a replacement for the 1932 PB Carter types 4A2 and 4A3, but I beleive it will work on the 28.  (Maybe someone else can comment on this to confirm or not?)

Another option would be to get a rebuilt Tillotson from a Ford Model A parts dealor.  I used one on my 29 for a while until I found an original Carter brass bowl type.  Unfortunately, I no longer have the Tillotson carb.

Chet,

It is hard to get a good picture of where the oil gage ine is connected to my engine - because the connection is hidden by the Starter. 

On my engine - the best way to descibe the location - there is an oil galley plug just above the oil relief valve.  If you draw an imaginary line from that plug straight back to the rear of the engine bock, the oil gage port is located there - at least it is on my engine.  It is so close to the starter that the oil line curves around the starter before going up and through the firewall.

PS - Note the brake fluid tank - it is different from any other I have seen, but it matches the description in the manual.  Even has a built in dipstick marked at 1/4, 1/2, 3/4, and full.

Chet,

I doubt you caused any damage to your car by cleaning and adjusting the oil pressure relief spring.  On a cold start at idle, it should read 35-40 lbs.  As it warms up, your idle oil pressure may drop to as low as 12-15 lbs, but should not be of concern. 

Your oil pump should not be mixing air with teh oil.  The previous owner did the  right thing by plugging the vacume port since it is not being used for the fuel pump vacume.  As for the vacume line - it does not draw much air if it is connected properly to a working vacume fuel pump.  It creates a vacume and should hold that vacume.  If air is introduced into the line in any great quantity, the pump will not draw sufficient oil from the sump. 

As for the releif valve, the problem is, you have no way of knowing if someone else had adjusted the relief valve before you obtained the car (as was the case for my engine).

The relief valve spring should be set to let off excess pressure - above 40 lbs.

However, at some point Plymouth changes where they read the pressure.  On my 29U the gage reading was taken down stream from the pressure relief valve. There is no port on mine at the pump.  When I obtained a pump off a 28Q with a port on the pump (as in yours), I was able to take pressure readings at two points - at the pump and downstream, by adding an extra pressure gage. 

I have noticed that the oil pressure at the pump may read 45lbs, while the gage reading from the downstream port measures about 38 or less.  As the engine warms up on an extended drive, the difference gets greater.  At 40 mph, the pressure at the pump still reads about 40 lbs, but my downstream reading is about 30 lbs (probably because my engine has a worn cam bearing).

These engines are pretty hardy.  A worn engine may run fine on 25-30 lbs of oil pressure hot, and 10 lbs at idle, with no detriment.  Idealy we all want our engines to be "like new", and a completely rebuilt engine should be.  But extreme excess oil pressure is not a good thing.

If I were you, I would plug that oil vacume port,a nd adjust the oil pressure releif spring to about 45 lbs when hot and running about 40 mph.  Obviouisly, this is a trial and erro thing, so make adjustments small - half a turn at a time and test drive hot.

You are very fortunate to have such a good set of door handles.  The pot metal they were made of does not stand the test of time well.  I suspect the driver side handles and windshield crank may have been replaced, as these would experience the most wear.

Chris,

Not sure, but I think your carb may be a Tillotson.  I beleive they were sold as replacement carbs for Ford Model As.  When I purchased my 29U in 73 it had a Tillotson carb on it.

I see it looks like you have an original air filter.  Advise you hand onto that, they are harder to come by than the original Carter brass bowl carbs that came with these cars.

By the way, you are very fortunate to have such good interior handles on your car.  All but one on my car had disintegrated.

Head Torque?  Good question.

There are no official guides for the early Plymouth 4s.  I used to use 55-60 ft-lbs, based on a 36-42 Plymouth Service Manual (I do not have a copy, reference is from Plymouth, the First Decade web site.)  Now I use 60-65 ft-lbs, based on a Head Torgue guide produced by Tom Hannaford of the Antique Auto Cellar.

I scaned the guide, but it is too big to post.  I will email it.

Here is the torque procedure I use, based on Tom's guide:

1) Torque to 1/3 (20 ft lbs)
2) Torque to 2/3 (40 ft lbs)
3) Torque to almost full (55 ft lbs)
4) Torque to 60 ft lbs
5) Start engine and warm it up, then retorque
6) After first drive, retorque while still hot

See Attached PowerPoint for sequence.
