my stb/center wiper motor has quit and I am trying to remove the assembly and replace it. I am having a devil of a time getting the unit off. I backed off the nut on the outside and tried to pull the arm off but there is either a set screw, c washer or something stopping it from coming off. Could be corrosion or me being very dumb, never had to do this before!
I think its a AFI 1000 but want to remove it first before buying a new motor.Ranger 25 SC circa 2007.

Any tips ideas or solutions?

Hello Allen,

I believe there are two set screws in the head of the wiper arm where it mounts onto the motor shaft. Be sure you have loosened both set screws or you will continue having a devil of a time removing it. Another option I have seen is to use a Dremel tool and simply cut off the motor shaft. This of course makes it more difficult to salvage the wiper arm but, in the case of replacing the motor you may also want to replace the wiper arm. I would advise using copious amounts of grease on the shaft of the new motor so that you can more easily remove the wiper arm in the future.

Anti-sieze is a better choice than grease in my opinion. Just buy a small tube at the auto parts store. It can be used on a lot of boat applications.
 
Here is what I have done on several arm removals. There is a set screw on top. Remove it with an Allen wrench. Spray PB Blaster ( Napa stores have it) into the set screw hole and on the face of the shaft. Hold a paper towel under the area so as not to get the spray all over the place. Tap all around and then let it sit over night. The next day use a pair of channel locks so you can wiggle it and tap with a hammer as you pull. Eventually it slides off the shaft. When you reinstall the arm use a little anti-seize and it will make it a much easier job to remove on another day when you decide to go with an imtra arm that seems to work better than the stock item that came with the boat. 😀

Hi Dave, got it! Had to use a small battery terminal puller with a head of a nail with a dab of silicon to hold it in place to get into the small opening on the blade arm, but it worked.

The longer we own the more we learn!

Glad to hear you got the wiper arm off! Hopefully the replacement of the wiper motor will be uneventful.

Hi guys: likewise, I have been having a terrible time trying to remove the centre wiper assembly and motor from my vessel. There is a lot of slack in the shaft and I suspect it is worn worn with age, etc. I noticed that there are a couple of Allen set (grub) screws on the outside, which hold the wiper arm onto the motor shaft. No matter how hard I try I cannot loosen them. With time, corrosion has occurred resulting in electrolysis - I presume they are a non-ferrous alloy. I was wondering does anyone have any other suggestions: other than cutting off the shaft and replacing the entire assembly? In the old days, at sea in steam powered warships, we just used a 'hot spanner' (oxy acetylene torch) to loosen/remove everything and then used anti-seize when replacing parts. Always worked. Unfortunately, in these days of hi-tech equipment, alloy materials and fibreglass, not an option. Oh, well, any thoughts, anyone? Stevan
 
Hello Stevan

Try to get some penetrating oil into the wiper arm/shaft junction. If the set screws prove to be UNremovable then you have no choice but to cut the motor shaft.

If the set screws are sufficiently accessible, drill them out and then put the "blaster stuff" in the former set screw holes...maybe an intermediate step to cutting the shaft...
 
My starboard wiper motor went out and I started looking into how to replace it. The motor is an AFI 1000 which apparently is pretty common because I found threads on all kinds of forums that talk about replacing the motor and difficulty in doing so.

So, I ordered a new wiper motor from Ranger Tugs and paid about half of what they were going for elsewhere including Amazon. The motor came this morning and I replaced the faulty one but decided to document my effort with a video. I figured I would either be successful or I'd end up with a good entry for America's Funniest videos.

The video is here https://youtu.be/DepfdbIhluE if you're interested. Turned out to be a pretty simple exercise.
 
Great video.. Very nice job.
 
Thanx for taking the time to do this. If I ever need to do this job, I can proceed with much greater confidence than I could have otherwise.
 
Great video! I didn't know about the wiper puller. I had to hacksaw one of mine off and replaced the wiper and the motor.
