Dear Dr. Crankshaft:

Q: Where can I get the condenser that is on my cross ram engine? Mine is missing.
A: Order #4048494 capacitor from your Chrysler dealer. It is as original except for part number.
Q: The 4 groove pulley on my air conditioned 300 has come apart at the rubber. Are new ones available?
A: No, but contact the dealer and order the “new type” that is solid (i.e. spot welded together) and is used on later models.
Q: My starter is slow and sometimes won’t work.
A: Before rebuilding, check to see if oil is leaking on it. If so, remove and clean the contacts in the solenoid. Also the ground tang may be rusted inside. Clean it up and you may save yourself a rebuild charge.
Q: Which carb is correct for my 1965 300L? Books and parts stores show 2 types.
A: For automatic transmission - #3860, for manual transmission - #3859. Only difference is throttle linkage.
Q: Where can I get a new or rebuilt correct fuel pump for my 60 & 61 300s?
A: Part number 4751 is the correct one. It is the large diaphragm with a bolt together housing. Carter, Airtex and Kem carry these numbers.
Q: The clock in my 1962 300 doesn’t work. How can it be repaired or replaced with a quartz unit?
A: Get a can of electrical contact spray at a radio shop and spray liberally on the mechanism, dry thoroughly and purchase some sewing machine oil and lube all pivot points except the balance wheel. Then use some 400 grit sand paper and clean the points. Check to see if the hairspring is not broken. Hook up to 12V before installing to check operation. Quartz movements do now allow the use of electroluminesent face and hands to glow. Also expensive.
Q: My 413 block is cracked. Will a New Yorker or Imperial work OK?
A: Yes, but use the original crank out of your engine as it is forged and has hardened journals and is balanced at the factory to a greater degree – within 2 plus or minus grams. Imperials and New Yorker are done at 15 to 20 grams. Also use tri-metal (soft) bearings.
Q: What is the difference between 1034 and 1157 bulbs? My car has 1034 and I can only find 1157s. They look the same.
A: 1157 bulbs are of heavy duty type and have longer life.
Q: I need a top for my convertible but have been quoted $400 to $800 for one installed. I can put one on myself.
A: Check the JC Whitney catalog. $160 for a lifetime guarantee.
Q: The wire stands for the spark plug wires are coated on the end (or are supposed to be) but have deteriorated. How can they be restored?
A: Go to NAPA and order black Plasti-Dip. Do not dip but use a dime body/acid brush and brush on the coating to the desired thickness. Make sure stand is clean and free of oil and grease. Leave dry a couple of days and repeat the process if needed, then paint the proper engine color.

Dear Dr. Crankshaft:

Q: What is the correct radiator for my 1960 300?
A: #1903358 for A/C, #1904808 without A/C. For 1961, #1904811 for A/C, #1904808 without A/C.
Q: Where can I get brass freeze plugs for my 1961 300 block?
A: Pioneer (Barnes Group) has these under #EP-14-B (1-5/8”). These are the saucer type, not the cup type.
Q: The gauges (oil, temp, gas) keep burning out on my 1960 300. I have replaced the oil gauge that supposedly controls the voltage. What is wrong?
A: 1960 had two types of oil gauges. One made by Stewart Warner with internal voltage regulator and one by Chrysler with an external regulator attached to the back of the speedometer housing. If you use the Chrysler gauge without the regulator, 12V current will blow out the oil, temp, and gas gauges. The voltage regulator limits 7.2 volts to the gauges.
Q: The distributor for my ’57 300 is beyond repair and I can’t find a replacement. Any ideas?
A: Yes, locate one from a 1957 or 1958 New Yorker or Imperial. They are completely interchangeable with only extremely slight differences. Also, an early low-block 273, 318 dual point distributor is almost a drop-in except the shaft is 1” shorter than the hemi. If the shaft on your distributor is OK, make an exchange and change the vacuum fitting on the chamber from hose type to fitting type and use the chamber spring and washers from yours.
Q: My starter sometimes stays engaged when the ignition key is in the run position. Why?
A: Could be that the small return spring on the end of the plunger has lost its tension, or that it is broken. A solenoid repair kit is available through NAPA (#STK12) for about $10. Fits ’56 through ’61 direct drive starters.
Q: I would like to know what are the original and the after market tail light lens identifications for the 1957 300.
A: Original lens is marked CHRCH at bottom of reflector, AL at the top of reflector. Left side has part number 168993LT and right has 1689932RH on rear edge of lens. After market has CY4 below reflector with VB at top of lens for the left lens, and for the right lens has CY3 with VB at top. Another lens is CY4 with TMC above reflector and VB at top (left); right is CY3 with TMC above reflector and VB at top.
Q: You say the 1960, 1961, 1962 clocks can’t be converted to quartz because of electroluminesence incompatibility?
A: Foot-in-mouth here, I’m afraid. I’ve been made aware of a quartz changeover to original operation by Kohler Clock Shop, 1930 E. Colorado Blvd., Pasadena CA, (818) 792-8991. Cost is $100 including shipping.
Q: The windshield wiper switch on my ’62 300 is bad and the dealers don’t have any. Where can I get a new one?
A: Phone your local NAPA store and order Echlin #WS6456 (Chrysler #2084267) or visit some friendly junkyard. A good used ’61 will work also. ’60 will not work because it works on vacuum. ’61 & ’62 have an electrical switch piggyback on the main wiper switch.
Q: Looking for brake shoes at swap meets really confuse me. Prices range from $8 per axle to $25, but there seem to be many variations for 2-1/2” x 12” drums.
A: Below I will show you the differences. Also, relined shoes by various companies are in the $50 to $70 range, but you can specify what oversize to put on depending on how much metal must be taken off the drums, then get shoes arced to the correct drum turned size.
