B2650/3350 Cab Rear Wiper Replacement

Rcflyer330 · Jan 13, 2020

Has anybody replaced the rear wiper blade on their B2650 or B3350 cab model?

I have been searching and searching but can't find any information on a size or part number except the entire arm for ~$80. I have tried to remove it but it doesn't want to come off and I do not want to break it.

Thanks in advance

I don't have a B2650 or B3350 but I do have a B3000.

I have replaced the rear wiper blade and I used this replacement blade and it works very well.

I think the cabs are pretty similar to mine so maybe that can work for you also.

Can you post a few clear pictures of the blade/arm interface for a few different angles?

There are only so many ways wiper blades attach to the arms, but it's always possible Kubota came up with a better idea.

Is there any chance the rubber insert can be changed? This use to be a popular method, but has lost favor over the last 10-15 years.

My Grand L cab uses the common j-hook, but that is of no value to you.

Thanks I will try to get some pics later tonight. I will say It's not a standard j style wiper arm it's completely plastic.

If I can't find a replacement i will just change the rubber part.

I don’t have any answers other than a wiper issue came up a few weeks ago.
Don’t recall anything specific about it, but wanted to mention while I thought of it.

Didn’t have time to research it right now, but if it helps the OP, that’s great!

Okay, while I was taking pictures I figured out how to remove the rear wiper.

To remove the rear wiper blade you need to pull the blade half under the arm past its angle stop. After that it comes right out.

Pic 1 is the assembly.
Pic 2 is the arm end with the wiper removed.
Pic 3 is the blade at the angle it needs to be at to remove it.
Pic 4 is the blade removed.

Funny thing is I looked at the assembly mulitple times before I decided to create a post. But for some reason while taking the pics I tried one more time and figured it out. Hopefully this post can help someone else out.

When or if I find a replacement I will post the brand and model number for reference.

Thanks for the help.

Great description and photos! I'm certain other B2650/B3350 cab owners will find this helpful as their blades wear out.

You'll have to post back the blade # that will work with this mount. With any luck any correct length replacement blade will work with one of the many adapters that seem to come with them these days.

I can't help but think the lack of PN or callout in the parts diagram is not intentional to maximize profits and screw the customer. I'm all for them making a profit, but there are times when companies seem to be taking advantage of their customers.

That's the same design as an Asian SUV (Rogue / RAV4 / Pilot) rear wiper. Post a length and I can probably get you a part number.

I was going to say...that kinda looks like what is on the rear window of my VW Tiguan?

I have never had it off though so not sure if it is the same.

Length is 12"
Looking at some picture online the Toyota RAV4 looks to be the closest one. It makes sense too being Kubota and Toyota are both Japanese companies.

Probably...." Maybe" is closer.
There are now 5 Roc-Lock designs ..... there used to be 2. Definitely take the old one when you go.
Trico numbers are:
12-A <<< I believe this is the one
12-B
12-F
12-J
12-K

Rcflyer330 · Jan 14, 2020

Here is what fits... I tried a trico rear 12" 55-121 using adapter A and it works fine.

Pau7220 got it right with the 12-A blade that is the exact replacement size.

Hi War Eagle. I also have the B3000 and need to replace my wiper blades.

The dealer wanted $25.00 EACH for the Blades.

So I'll try my luck with the ones you show from Amazon. ($13/each)

I measure the Front blade at 16" and the rear blade at 12". Does that seem correct?

How hard is it to remove the old one?

Thanks !

I went out and measured my blades and the front one is pretty close to 17 inches and the rear is 12 inches.

Both the replacement blades have been working fine and they have been in place for 2+ years now.

The replacement blades have the J hook shape and they were not hard to replace. As I remember the new blades came with a small piece of paper showing how to install.

Good luck
