Cobra Trailer Screw Jack
I have a screw jack on my 2012 cobra trailer that becomes very difficult to
operate after every 2 or 3 uses in order to jack up my ASW-27B for disassembly. The glider is operated in a sandy environment and the screws become dirty quickly. Anyone have any idea about how to avoid the necessity for frequent cleaning. I have used hydraulic jacks in the past but I got tired of them leaking and collapsing. Thanks, MC |

Use dry film (NOT WD-40 or similar crap) but real moly disulfide dry film lube. Molycote 121 IIRC, is a product that comes in a can, one can will last decades, as long as you don't use any thing else...you have to be able to completly clean the part free of grease or oil first... aerodyne |

Back up a bit and tell me about Cobra hydraulic jack failures - I've just decided I just upgrade from the screw to the hydraulic, I operate off grass. Is there a history of problems with the Cobra hydraulic system? What has been the experience of other Cobra users? Anyone care to venture an opinion? ZB |

I replaced a totally worn out (circa 1985)Cobra screw jack with a Cobra hydraulic jack about 3 years ago, time split between midwest and west (desert), and havn't had any problem with leaks, etc. I do make sure the valve is shut at all times except when lowering the ramp. I also replaced the big Cobra jack actuating lever with a small butterfly nut. Not as convenient, but not as finicky either, and less chance of munging up the valve. Bottom line - I love it. So much easier than a screw jack. Highly recommended. YMMV, of course... Cheers, Kirk 66 |
