4788 wiper arms-gctid816603

[Carlo]

My pantograph wiper arms are in need of replacement. I am tired of wire wheeling them off every two years only to have them rust again causing 3 rust stains under the windshields.

Has anyone found a supply of stainless arms to replace the old ones?

I have located a source, but I feel they are over priced.

Cheers

Am equipment has everything you need

the 28" pantograph arms, new base plates, blades, and dont forget new hardware kits ran me around 330 plus shipping if memory is correct.

Carlo, if you get a s/s arm option, pls share it. I guess it'll be expensive. As far as the blades/rubbers are concerned, in Costco (USA) they had 28" Goodyear combo blade rubbers/holders for us$10 each. They don't have that size down here but check them out. Just a slight adaptation but for $30, just the ticket!

I tried the Costco ones and they didn't fit

Went to Canadian Tire and got a set which fit ok but

the blade has a slight curve in it (as do most auto windshields)

The upper part gives a clean window swipe and that;s where you look out

so I am ok with Canadian Tire ones .Paid approx $70.00 for the three blades

Will post the name later (packaging on the boat )

Ron, there was a slight adaptation/filing the plastic edge a smidge wider if I remember where it attaches to the arm, but other than that, they work just fine. Cheers

I too had to do the filing. Blades sweep clean but after one year are unsightly from rust.

Rather than spending tons on stainless is there an argument for individual wiper covers?I have seen them on lots of boats but don't know if they are effective.

I was thinking about removing the arms and such and sand blasting them and then powder coating them. Any opinions on that idea?

The ones that were on my boat were alumanium and they were corroded fairly badly. Also I could not just get them off. I tried a little gear puller and in the end used a dremel cutter and carefully cut them, then pried open the cut with a screwdriver.

The new ones from A&M are stainless, but painted black. I think the old ones are OEM, so they are 15 years old. That seems to me to be a pretty good lifespan considering they are in a corrosive enviroment.

Joe, I haven't had a issue with my Costco specials, mind you, they are covered. The windscreen fitted cover is tight and the sun down here heats and bakes the rubbers if they are left against the glass. Against the canvas is not much good for them either, so I figured I'd run up some canvas pockets/sox to slip over the retracted arms/blades. Looks goofy, but the rubbers and arms are as good as new.

Royalty payments are negotiable :whistle:

Cheers

Does Coltco sell both the arms and blades?

Hi Guys

As per Mr. Sanders suggestion, I contact Shauna at AM Equipment and got a solution.

It involves swapping out the backing plate as the old old's were 1 1/4 center to center and the new ones are 1 3/4" C to C.

I bought new knurls as well as the old ones will probably not going to come off easily. They must come off to change the backing plates.

Here is what I bought

3 of 750-2800 Arm, CD, 28" Panto, Dry, HS, Tapered Knurl, 1.75 Bridge $52.75 each

3 of 305-1007 Assy, Pantograph Adapter, 1.75" O.C. $16.96 each

3 of 407-1097 Knurl, 0.70", PM, DFS, Zinc Plated $4.08 each

Cheers

Mickey, Costco only sell the blades being the rubber and holder, not the arms. As mentioned before the Costco assembly require a little filing where the arm connects to the blade, but not a bad alternative for $10.

Cheers

Knurl.?

There is a small fitting that adjusts the range of motion, inside the cap. It has gears. Is that a knurl.

And...thinking that john's socks are the ticket!

The shaft sticking out of the boat has two flat sides and is threaded.

There is a tapered part (called a knurl) that slides over the shaft. This tapered part has about a zillion grooves cut into its outside surface.

The wiper arm goes over the "knurl" and can be lifted off and rotated to change were the wiper comes to rest.

A nut is threaded onto the shaft holding the wiper arm and the knurl on.
