Ted,
Please don't put Firestones on them, Mr. Chrysler would not like that, being Ford Model A tires!  The original were Goodyear diamond tread, but impossible to get.  Go with any good blackwall, but not Firestone!

Try calling A & W Bearing Supply Co. in Texas at

800-442-7773

If they do not have them, ask them to check the Timkin interchange guide.

RIV 063513 will interchange with Timkin 09074.

You should be able to order the bearings thru any Bearing supply store.  These are still used on other applications and are readily available last I checked.  Don't wast your time at an auto parts store.  Look up "Bearings" in the yellow pages and find an industrial bearing supply store.  Or, you can order them on line.  If you rather have NOS, call Tom Hannaford at Then and Now Auto Parts.

Front Outer Cone (roller bearing) is # 09074  (Number 09074 was used on 28-48 Plymouth and 28-48 Ford cars)
Front Outer Cup is # 09194
Front Inner Cone (roller bearing) is #14132 (14130 and 14131 will also fit.)
Front Outer Cup is # 14274
 
The grease seals are available at the auto parts stores, but use the part number:
National    473450
Car Quest, ABD    473450
Chicago Rawhide (C/R) 18242

The copper brake line is 1/4 inch OD.  You can readily get modern 90-10 copper nickle that is approved for brake lines.  Do not use hardware store stuff on brakes.

General Discussion / Re: Oil Pumps and Oil Pressure - A survey question
« on: February 13, 2011, 05:52:58 AM »
Thanks again Chet!

After rebuilding  my engine and cam shaft, I adjusted my 29U pressure relief valve and now get the following:

Cold:  45 psi at pump, 40 psi downstream

Hot:   40 psi at pump, 35 psi downstream

Hot idle:  20 psi at both locations

I think this should be fine now.   My 29 Manual states the pressure should be 35-40 psi at normal operating speed, and my factory gagae was set up to read from the downstream port, so it seems to be right on target.

After ths experience, I am convinced that he main bearing wear that most effecs oil pressure is the center cam bearing.

PS - If anyone has a 28Q manual, I would be interested to know what it states the normal oil presure should be, since those engines took the reading from the pump.

On my 29U the flywheel will only go on one way. 

When I had my engine balanced, the machine shop did not use the clutch, only the flywheel, crankshaft and pully.  It runs smooth.

I do not think one slightly oversize hole and bolt would make that much difference.  That is only a few grams, not enough to matter.

Thanks Chet - that helps!

As for the location of the oil port behind the starter, it is a screw plug where the oli port was drilled to connect the mail galley to the rear main and rear cam bearings.

If you look on the front left side of the engine, there is a plug with a square drive where the main oil gallery was drilled from front to the rear of the engine.  If you look just above the oil pressure relief valve, there is a slotted screw plug.  This plugs the hole where the oil port was drilled to the center cam bearing and center main bearing.  If you go forward and aft from this oil plug, you will find two smaller slotted oil plugs, one at the front (behind the water pipe), and one at the rear (underneath the starter).  You may be able to feel the one under the starter with you hand.  This oil port plug is where my oil pressure gage line is connected.

Some of my 29 Plymouth rims have the same lever, but not all of them.  I do not know which are original.

General Discussion / Oil Pumps and Oil Pressure - A survey question
« on: January 17, 2011, 06:15:15 AM »
 :P   I am rebuilding my 29 Plymouth engine (SN U50105).  My car was manufactured approximately May 15, 1929. On this engine, the line to the oil pressure gage comes off an oil galley port on the left rear of the engine under the starter, near the rear main bearing.  I obtained a 1929 parts engine (SN U29287) that was manufactured earlier than my engine.  On this earlier engine the oil line to the oil pressure gage comes directly off the oil pump. I am using oil pump from the parts engine on my rebuilt engine.  This has allowed me to place a second after-market oil pressure gage in my car, with the "new gage" showing the pressure at the pump, and the original gage showing the pressure at the other end of the oil gallery.  When I run the engine, the difference in oil pressure between the two is 5-10 lbs when running at operating speeds (30-40 mph).  At warm idle the two register about the same (~20 psi).  Also, the gage measuring the oil pressure at the pump fluctuates quite a lot, while the oil pressure measured downstream on the original gage is much more steady.  
    Now - I am trying to set the engine oil pressure.  The "May 1929" manual states the oil pressure should be 35-40 psi at normal operating temperature.   I have set it so the oil pressure at the original downstream gage is 32 psi when warm, and the pressure at the gage is about 38 psi. When the engine is cold and run at 30-40 mph, the pressure at the pump is about 45 psi - until the engine warms up.  I hope this is OK?
 ???    My survey question is:
1) What year is your car?
2) Where is the oil pressure line connected - to the oil pump or to the oil gallery under the starter?
3) What is the max oil pressure when run at operating speeds - cold and hot?

John

General Discussion / Re: Distributor slop
« on: January 17, 2011, 05:48:21 AM »
Not sure exactly what you are describing, but it you are talking about the slot at the end of the cam shaft where the distributor connects, I would not be concerned about it.  The slot is off set slightly so that there is only one way to connect the distributor to the camshaft - so you do not get the timing off by 180 degrees!  
If you are talking about that you can turn the distributor shaft where the points are, there is movement there due to the springs in the semi-auto advance system - which is how it is designed.
I suspect your distributor is just fine.  Be very careful pulling the distributor off.  The housing is pot metal and can break.  You can get a new housing in brass, but they are expensive.

I noticed one is a flat pan head with no slot.  These might be a friction pin.  You may be able to get one from a Ford Model A parts supplier.

There was a "Red Dome" head, but don't know much about it.

I do not think mine are original.  They are machine screws, slotted pan heads.

Not sure exactly what you are asking, but the screw does not go through the interior door cloth and panel.

Walt Tallberg may have a spare, as i have gotten several parts off his two parts cars.  Try:  wjt1488@windstream.net  or try (870) 447-3043  (Arkansas)

If not, you could try Ben Ostranger (Alberta, Canada), but he may be South for the winter!
