View Full Version : Another UFP Swap Thread

Having had a fair amount of trouble with my Titan actuator, I've decided to swap it out for a UFP actuator. Also, my race trailer and the wife's horse trailer have 2 5/16" couplers. I've always felt that my MC trailer should also have a 2 5/16" coupler instead of a 2" coupler, given the weight. Thus, I ordered up the 2 5/16" UFP coupler. Hoping to start the cutting and welding this evening. I can tell you one thing, this bad motor scooter is stout. Way, way, way more stout than the Titan actuator it is replacing. The other big factor that makes me smile is the alumn master cylinder. The Titan has a cast steel one that rusted and was impossible to keep from rusting. Besides those improvements, another bonus is the external sleeve and internal components can be easily separated. Thus, should things go badly with the actuator, one can purchase and quickly replace the internal unit and not have to mess with the external sleeve (which will be welded in place). That's pretty dang cool. I'll post up the down-n-dirty as I make the swap, but here's a teaser anyway:

Would you consider selling me that chair?

Nice, isn't it? Love library chairs. Love library tables even better.

So does that translate to yes or no?

So cut off the old. Left the side wings (the part of the orig actuator housing that was splayed and welded) to keep the spacing correct. After doing all that work I came to realize the wings were actually crooked (more of a twist). So, just going to zip them off tonight and go that route. I'll weld the top plate in place, bolt it all together (using two bolts and proper washers to get everything just right), then tack and weld the lower plate.

The 2 5/16 actuator is considerably longer than the Titan actuator it is replacing. I cut 2" off of it, which still leaves the works approx 2" longer than the previous setup, which is great.

One other thing. With the old setup, all braking force was transmitted to the swing bolt and pin. What I'm doing is positioning the actuator sleeve so it butts up tightly again the stationary trailer tongue when the swing arm is in its locked position. That way the braking force is transmitted to the blunt edges of the welded housing in addition to the bolt/pin. Can't do anything about the bolt and pin getting the stress when accelerating, but at least when braking, they don't have to carry the burden alone (not that it was ever a problem).

Bottom plate now attached, self-etching primer and black paint (sans the internal mechanism of course):

Bleed tomorrow and done.

All done and works great. A quick review:

Pros: Very heavy duty; smooth action; separate sleeve and internals; 2 5/16" (in my case); very high quality welds and zinc plating; alumn master cyclinder; comes with backup solenoid installed.

Cons: Can not unhook if the brake actuator is fully compressed (I now have to block my trailer wheels so I can pull forward to disengage the actuator after backing boat into my shop), break away cable exits directly in the front (can get pinched (damaged) between actuator end and hitch when backing up to the trailer if you overshoot it); the coupler socket is very deep so get ready to do a lot of cranking on the jack to get it to uncouple (in part because of the larger coupler and in part due to the deep socket -this is not necessarily a bad thing, but my factory installed Fulton jack is not up to the task.).

Despite the few foibles, it is the much needed improvement over the original Titan actuator.
