Re: How do I lube a shift cable?
If the first one broke, make sure that the cable is the real problem. With the cable not connected, do the control levers move free and easy?
While the engine is idling and tied to the dock, can you shift the engine in and out of gear at the engine cable connection point?
Is the cable route from the shift box to the engine proper without any sharp bends or kinks?
IF the cable route is ok and your sure its just an old cable you could lube it by injecting a penetrating oil like crc and or liquid wrench.
Find a short piece of hose that fits over the cable end. Adapt or shim to have the other end of this hose go onto an oil can or a funnel.
Tie the funnel and cable so it is the highest point and pour the mixture of CR & Marvel mystery oil into the funnel so gravity will cause the mix to enter the cable.
This works better if you can pump our use positive pressure to get the oil to flow into the cable.
All this work to save an old cable that costs about $40. The other down side is the cable might just freeze up again, Penetrating oil works to free up stuff, not keep it free.
