We have the AFI wiper motors in our CD-25. The starboard side has always been sluggish, and recently just flat quit. The new motor arrived yesterday... but I have no idea how to get the wiper blade off??? Any suggestions/tips would be greatly appreciated.

I did several web searches to try to find out how those arms come off, to no avail. Thanks in advance for any info you can send my way.

Best wishes,
Jim B.

Mine have a pinch bolt(10mm head)clamping the wiper arm to the splined shaft. If no pinch bolt then they just pop off! Mr. Green Beer

OK, no pinch bolt that I can find... I have some concerns about just yanking on the arm (I'm gonna have to reuse that). Any tip to make it "pop" off?

Thanks again.

Best wishes,
Jim

OOPS forgot about the nut possibility, Semi gently pry up on the rear of the cap covering the wiper shaft(big end of arm) might have a nut under there? or a little clip to push out of the way and lift off.

OK, tried the gently prying... no joy. Fortunately, the boat is right out the door, so it's easy to make these trips. Wink This is the pantographic arm, if that makes any difference (two connections on the wiper arm to the boat).

What's the saying? Oh yeah, "if it was easy, anyone could do it." Crook

Does the new motor have a threaded shaft above the splined shaft?

No, just the splined shaft. MarineCo (AFI) was very prompt in a reply:


<<In response to your inquiry on the AFI wiper products, we do not have
instructions on how to remove them, only how to install them (see attached).
Our guess is you are referring to removing the "arm" from the motor shaft.
If so, first make sure that any set screws or spring clips have been
released. At this point it's just a matter of lifting it off the knurled
end. Sometimes they're very difficult to remove due to corrosion buildup.
If this is the case, spraying a little WD-40 on the corroded points and
letting it sit for a few hours or so should loosen things up. If that
doesn't help, you may be forced to cut the shaft of the motor and replace
the whole system.

Good luck, and let us know if we can be of further assistance.>>

The attachment they sent was in Word format, and I can't open that. Neutral I'll keep looking.

Thanks,
Jim

When it does pop off you are going to think O that was easy Mr. Green Beer get out the penetrating oil & hose it down. Have a good one

There is a set screw that holds the wiper to the shaft. I think it is under a hinged protective cap. It is a bugger to get to since it is so close to the roof overhang. Once that is loosened you need to work the wiper off the splined shaft. Then you need to take off the nut that secures the shaft/motor to the boat. There is also a single screw or nut (can't remember and I am in Maui right now) that must be removed that. The motor will then come off the boat.

WD-40 sprayed - check
Gently pryed cover - check
I can see the set screw - check
Set screw is a giant pain in the ass - check

I'll let the WD-40 do it's thing a while longer and try again. Thanks for your help on this, guys! Thumbs Up Less than 17 minutes from my first post to potential resolution - this place is great!

Best wishes,
Jim

The key word is "two" set screws. Once removed you will have to overcome the salt corrosion and than the wiper arm will come off. I found I had to get the arm in just the right position to release its pressure on the splined shaft. When I acheived that magic position, after much frustration and prying, the arm came off easily.
Good luck
Ron

James, my wiper arm (came with the motor) uses an allen head set screw to anchor it to the motor shaft. Having replaced four wiper motors in five years I can toss a couple of tips out for you.

Removal with the blade in the park position (my motors are above the window) is very cumbersome and makes the port side set screw unreachable. I turn on the wiper and shut down the main power feed so the wiper blade is in a down position for better access to the set screw.
The tension created by the spring load on the wiper arm will cause enough side loading so that the arm cannot be removed even with the set screw loose. I lift the wiper arm then pry on the back side of the connector to rock the arm off the shaft. If the arm and shaft connection has not been well greased removal can be a real PIA due to corrosion (even when lubed it is a PIA).

Do not do this on the water if you can avoid it. When the arm releases it tends to do so all at once and can result in tossing the arm into the water (believe that I have two arms on the bottom of the Columbia now)

Once the motor is replaced (great fun setting the sweep correctly) you will get in plenty of practice installing and removing the arm. It is a bit of a guessing game if you have the arm on the correct spline for alignment and you need to do this in the park position.

On the positive side with a three year warranty you can do what I did and buy a third motor to replaced a failed one and not be without a wiper while the broken one is being replaced . I actually have a rotation plan for these pieces of junk. When my starboard motor fails I move the port motor over to starboard and install my spare on the port side. Might be a northwest thing but I have yet to have a motor last much over two years and can now tell when the failure is starting to happen.

Good luck
stevej

I've never had a motor problem with the wipers on my 22 (now over 5 years old). Must be different motors/manufacturers.
