1970 Cuda Variable Speed Wiper Transmission - 03/01/15 12:43 AM

Hey there, I am finally trying to get my wipers working, but I'm not sure if I have the right parts. I have a 3 speed or variable speed motor, I'm trying to figure out if my transmission is for a 2 speed or a variable speed because the end of it extends about 1-1/2" - 2" past the back of the motor (see attached pics). Am I missing a part to connect the transmission arm to the motor? Thanks in advance.

Looks like your transmission linkage is for a two speed motor.

Do you know what the number should be for a variable speed?

You need a 2822293 linkage arm and a 2822289 wiper link.

Oh okay. I found two on ebay that claim to be 70 cuda 3 speed transmission arms but they read 2822-291-58622. How does the correct arm connect to the back of the motor?

The link (2822289) is attached to the wiper with a nut. The link has a stud where the linkage (2822293)is attached with a spring washer and lock retainer. Bob

Oh great thank you for the pictures. So I guess the 282-2291 part I saw on ebay is for a different year model?

The 2822291 is the link that will connect the the left and right pivots. Same on a 2 speed.
The drive linkage is different and the one you need

There is also a very thin steel washer and a rubber washer between the crank arm and the linkage arm. I also did a quick look on ebag using "cuda wiper linkage" there are no correct parts for a 70 3sp.

from the (Jan. '72) 1970-71 Parts Catalog:
BARRACUDA & CHALLENGER

2822 289 = CRANK w/PIN, Wiper Drive Variable Speed (same as '71 B-body)
2822 290 = CRANK w/PIN, Wiper Drive 2 Speed (same as '71 B-body)

2822 291 = LINK, Wiper Pivot Connection

2822 292 = LINK, Wiper Drive 2 Speed
2822 293 = LINK, Wiper Drive Variable Speed

Yes Bruce, very hard to find. No one making them.

The rubber one is a home depot item in the hardware isle. They are in the pull out bins. In SOCAL they are Everbilt Neopren Washer 3/8 x 13/16 dia the skew #887480157581. If you happen to have any E-body wiper transmissions around there are several installed in them.

Is there any way to get a 71-74 wiper linkage to work on a 70? Are they the same length?

Or I guess it would be 72-74?

not sure what is different besides the part numbers

from the (Nov. '71) 1972 Parts Catalog & (Sept. '72) 1973 Parts Catalog:
BARRACUDA & CHALLENGER

23-67-76
3431 518 = CRANK w/PIN, Wiper Drive Variable Speed
3431 553 = CRANK w/PIN, Wiper Drive 2 Speed (same as '72/'73 B-body)

23-67-79
2822 291 = LINK, Wiper Pivot Connecting

2822 292 = LINK, Wiper Drive 2 Speed
3431 514 = LINK, Wiper Drive Variable Speed

Yes you can with the right combination of parts. If you have a 70-71 motor you would need to change the drive pin inside the motor and then use the 3431518 crank and 3431514 link. If you don’t care about the numbers on the motor you could use the motor, crank and link off any 72-74. If you are going with the 70-71 motor and changing the drive crank there is a timing issue inside you would have to deal with. Contact me and I’ll help with that.

The main difference is the height of the brass bushing. There were some wear problems and the parts were revised with a taller bushing

Can I use a readily available 2 speed ’72 Charger wiper motor to replace my near impossible to find 2 speed ’71 Charger wiper motor?
*I realize I could get my ’71 2 speed motor restored/repaired, but all I’m looking for is a basic parts store price and quality

*The ’72 wiper motor looks the same as my β€˜71, but I am aware that the ’71 B body uses wiper crank/pin arm 2822290, whereas the ’72 Charger uses wiper crank/pin arm 3431553

When I look at pictures online of these two crank arms, they look virtually the same?
So my question is: will I be able to use/mount my 2822290 crank arm on the ’72 motor shaft?

Update for ’70 & β€˜71 E-body, and ’71 B-body 2-Speed Wiper motor replacement:

I have learned that the readily available/affordable parts store ’72 Charger(’73 Challenger) wiper motor is a direct bolt in, and the ’71 linkage crank arm will bolt up, but is a bit loose due to the ’72 motor has a smaller shaft.

For me, this resulted in sloppy wiper action: The wipers wouldn’t cover as much windshield, and the would not park properly(wouldn’t hide away completely) – due to the slop.
Also, the ’72 motor shaft Parks/stops in a slightly different position (*this probably also attributes to not parking in the correct position).

Upon further investigation I found out the ’72 Crank arm motor shaft rectangular cutout is at a different angle than the ’71 Crank arm.
So, I purchased a ’72 crank arm(pt#3431553) on eBay to go on my ’72 motor. It fits perfectly w/no slop. Now my wipers work perfectly and park perfectly, - like brand new!
