I recommend rebuilding the master cylinder.  You can do it yourself.  A new (not NOS) master cylinder kit is fairly inexpensive. (Buy from a brake parts specialty company.) 

I would also replace the brake shoe return springs.  Over time they become weak.  If the spring does not pull the brake shoes in, the front shoe will grab (when going forward.)  I bought some new from Roberts for $7 each.

I have stored my 29U car's tools there under the rear seat for years - air pump, jack, wrenches, etc.

General Discussion / Re: Oil Pressure
May 17, 2008, 11:01:44 PM
The pump draws oil from the sump via the long copper pipe that attaches to the top of the pump - this pipe goes thru the engine block just abov ethe oil pand and then to a vertical pipe to the sump filter screen.

The oil pump pushes oil out the smaller forward side U-shaped copper pipe that attaches to an oil galley port in front of the pump. 

Here are a few tips for priming a 1929 Plymouth (I have used them all):

1)  Remove all the spark plugs.
2)  Remove carb.
3)  Remove Oil Pump and put oil in it by either:
     a) Use some 90 weight gear oil that comes in a tube and put oil in the intake port (top of pump), squeezing tube slightly while turning oil pump by hand.  This is messy, but works well, and you can tell right away if the pump works, or,
    b) Remove cover and pour oil in it and replace cover (while cover is removed, check that the vanes and springs are in good shape), or,
    c) Remove cover and pack with vasaline and replace cover.  The theory is that when the oil gets hot, it will wash out all the vasaline.  (This works well, but I was surprised to find vasiline in a "nook and cranny" of the pump when I disassembled it many miles later.)
4)  Using some 90 weight gear oil in a tube, put some oil into the draw tube. (The long upper tube)  Squirt it in under a little pressure.  This way you can also tell if the line is free to the sump.  You may find it helpfull to remove the crankcase vent for easy access.
5) Reinstall pump.
6) Using starter, turn engine over with the spark plugs removed untill you notice oil pressure on the gage.  This may take a few minutes.  If no pressure appears after 60 seconds, stop, let the starter cool a few minutes, and try again.  You should get 10-20 lbs of pressure when it primes.

Now regarding trouble shooting - if no luck on pressure, try:

1) Remove U-shaped copper pipe from front of pump.  With spark plugs removed, one person turn engine over with hand crank while the other watches to see if any oil comes out of the pump.  If oil comes out, pump is OK.

2) Remove oil pressure gage line and check that it is clear (not obstructed). 

3) If the above checks out, and you still cannot get a prime or oil pressure, even with a new gage, then you may need to use a device that will externally pressurize the oil system.  I made one using a new one gallon pressure sprayer from the hardware store.  I removed the spray nozzel and installed a presure gage, shut off valve, a flare fitting.  I put a couple of quarts of oil in the hand pump, then attached the hose to the galley port on the engine (bypassing the engine's oil pump).  I then pressurized the tank (with the attached hand pump).  If the oil galleys are free, oil will flow from the tank through the system and drain into the oil pan.  (It is best to empty the oil from the engine oil pan completely before you start this test.)  Also, this test will tell you if there is an opening to the engine oil gally that is preventing the oil from building up pressure.  If so, you will notice the oil rush out of the tank and quickly fill the engine's oil pan.  If everything is working properly, oil pressure should build up, and the external oil tank should slowing empty into the engine.

If you want, I can take a picture of this test device.

Good luck.

General Discussion / Re: 28 / 29 Interior
May 08, 2008, 09:40:42 PM
When I bought my 29U 4 Door sedan in 1973 it had the original interior.  It was in very bad shape so I replaced it all.  I remember clearly there was a map pocket on the front passenger door and on the rear driver side door.  My Mom was a good seamstress and made me new map pockets, using the originals as paterns.

General Discussion / Re: Leaded or Unleaded?
April 27, 2008, 11:19:52 AM
Yes - just run it on regular. 

Even at that, you will find that if you try to set the timing by the owner's manual, it will run rough, if at all.   Reason is, fuel in 1929 had a much lower octane and so ignitied much faster than today's fuel.  There are no timing marks on the 28Q or 29U.  You will have to adjust the timing by ear, advancing it somewhat.  So, if you try and set it by the manual, and it refuses to run, advance the distributor a little and try again.  The simplest method - once you get her running - is to adjust the distributor at idle to obtain the fastest rpm, then turn it back just a hair.  You can also attached an RPM meter (set for a 4 cylinder).  There are other methods, and I am sure you will hear from others.

Good luck.

The 28Q and 30U did not have hardened valve seats.  There are many diferent opinions on lead substitute additives.  I use Bardahl Instead O' Lead on my 29U.  However, I do not use the octane boost version - these cars ran on much lower octane than we have today, so you do not need an octane boster.

General Discussion / Re: flywheel repair

The clutch throwout bearing has it's own return spring that is separate from the clutch pedal return spring.  On my 29U, it attaches to a small knotch on the bottom of the upper access opening to the clutch (i.e., the access opening that you use when putting grease into the bearing.)  This same spring was used for many years.  I recently obtained a new exact replacement from PowerWagens for just a few dollars. 

Rich Rodgers advertises on ebay and claims to have a good supply of both pilot bearings and throwout bearings for old cars.  I have never done business with him, so I cannot vouch for him.  Here is his email address:

Thanks guys - All is well with the fuel pump!

I took the 29U on several test drives this weekend and the pump is working well, and not overflowing.  I am amazed that the Kingston Vac Pump does not have any check valve to prevent gas from being drawn into the oil pump.  It appears Chet is right - the system is in balance somehow with a well vented gas tank. 

I put new gaskets on the old original gas cap, but ensured that the cap vent was well open.  The gas tank does not appear to be leaking any at the cap or gas gage, so all seems well and good.

George,
   I bought one from Carson's a few years back.  They had two more at that time, however, they were pricy at $60 each.  I could have done better on ebay.  They do not show up often on ebay, but every now and then I see one.  In any case, be sure you get a good description, as some of the old Master Parts lists for Starter switches are not correct.   Carson's, 235 Shawfarm, Holliston, MA 01746, PH: 508-429-2269
   If I were you, I would try and take it apart.  Most likely the contacts are burned. If so, you can sand them clean and reassemble the switch.  You have nothing to lose.  I fixed an old Model T floor switch that way.

Thanks guys.  I drained the vacuum tank completely, cleaned the lower unit out and made sure the upper vacuum tank was empty.  I cleaned the glass bowl and filter screen while I was at it, and put in a new filter bowl gasket.   I then added enough clean fuel to allow the engine to start.  I replaced the "new" gas cap with the original one, but first I checked it and made sure it had a good vent, which it does.  So now I need to test it out.  However, must wait till next weekend to do that.  Will let you know how it goes.

Thanks!

Chet,
Thanks.  I had put a new replacement gas cap on, since my original one leaked a bit.  I'll put the old gas cap back on the gas tank and try that.

The Original Kingston Vacume Fuel Pump has worrked pretty well on my 29 Plymouth for over 30 years.  However, this weekend the tank overflowed, and I believe fuel was being drawn into the oil pump.  I have aways wondered what type of check valve was used to prevent this from happening.  Now I will have to take the tank apart and find out.

If anyone has any experience with this problem, I would appreciate some advice.

General Discussion / Re: Inside door handles.
March 10, 2008, 11:27:26 PM
Years ago I put Ford Model A handles in mine - that was all I could afford at 17.  They look fine and fit perfectly.  Original type repoductions would be great, but pricey.  I still have some of the original handles - but they are unserviceable.  Will look for the original windshield crank.  The only original inside handle I am still using is actually a rear window knob that I moved to the front windshield.

General Discussion / Re: Floor covering
March 10, 2008, 11:21:58 PM
Chet, I do not think the floor rubber was glued down in front.  I used to have an original and it had a brown insulation pad glued to the back.  It did not fit snug around the gear/hand brake or pedals.  Separate rubber pieces with steel reinforcements covered those parts.  I wish I kept them but they were in such bad shape they were thrown out years ago.  The separate pieces can be purchased from Steel, but they are pricey.

General Discussion / Re: 30U rear main oil seal
March 10, 2008, 11:12:22 PM
Regarding the rear main seal - I agree - if it's not leaking much, leave it alone.  I have replaced the "new" type split steel/neoprene rear seal on my 29U without removing the engine.  I removed the Xsmsn and flywheel, then dropped the pan and removed the rear main bearing cap.  Then loosen the center and front bearing cap a little so the crank will drop just enough so you can remove and replace the top half of the rear main seal. Trick is to install both halves before the main cap is replaced.  I also recommend cleaing the surfaces good and putting some Permatex 300 or Aviation gasket seal between the seal and the block/cap.

If you have the original type rope seal, I do not have experience replacing those, but I am told they too can be done without removing the engine.

I would not install the new split type on 28Q, 29U or 30U unless the opening has been enlarged to fit by a machince shop (requires engine removal)- otherwise it will leak.
