Topic: 1949-51 Mercury vent and heater control cables


56MarkII    -- 07-24-2017 @ 7:54 PM
  As anybody else that has gone through this knows these cables are pretty much impossible to find from the "usual suspects" as well as Rear Counter and from time to time various other Ford and Mercury vent/heater cables come up for sale on ePay but have slightly different part numbers or totally different part numbers but have the same ends required to install on the control lever and vent/heater valve pins or dowls but the length might be longer or shorter. Does anybody know what the lengths of these cables are or have any idea of what can be substituted other than having to totally remove each damaged cable and measure each one hoping and praying something pops up for sale? I could remove and measure but:
A: It would be probably a good idea to reinstall so one doesn't forget how and where these devils are routed and installed (doing twice the work ) and
B: So they don't get lost or thrown out by accident or mistake.
Other than trying to locate this unabtainian hoping to find a usable substitute is there anybody that reproduces these cables possibly for the more common Fords that might fit?
I'm reminded of how difficult it is finding parts for Mercury after my overdrive lockout cable snapped off right at the anchor bolt within the pivot bushing on the transmission linkage due to a stiff bushing due to rust. Luckily I was able to barely push the cable back into the bolt and get it to catch so I could limp this cable along. The cables for Fords are very common but the d*mn knob is different than the Mercury knob that matches the park brake handle in the Mercury. The knob on my Mercury cable is locked on by a punch of sorts when it was made and I thought about removing it and putting it on a repop Ford cable or pulling the broken core or wire out of the shaft attached to the knob and installing a new core ( if I locate one) to repair this cable.

  There are different lengths for each year as the heater is different. The heater cable lengths are listed in the accessory section of the Chassis Parts Catalog.

The vent cable length should be shown in the Body Parts Catalog.

Here is a source for the manuals on CD

I am sorry that I cannot provide a source for the cables, just a suggestion that keep yours oiled (drip alight oil like 3in1 along the sheath of the cable where it does not have a rubber or plastic covering) and then look in junk yards for good used ones.

Too late for the oil as these cables broke off years ago. If they had a simpler setup for the ends I would consider replacing the cores in the housings but that wound loop at the end makes this a problem. Time to dig into my body manual and the only manual I don't have is the service manual but I guess time to break down and purchase!
