Wiper Trans/Bubba

[Brad H.]

My wiper and shaft can be dropped down the hole and put into place with pressure on the back end and set where it goes and will run about four or five revs then will pop out and then just lay where it popped out, Now I know this sounds nuts but what if one drilled and tapped the back end of the shaft then set the shaft back in place put a srew and plastic washer in making sure to bottom it out in new threaded hole and leaving a 1/16 gap so it could move on the back side of the pulley housing, would this work, or mess something up, yes I to am thinking of time and no idea of how to reassemble this whole project. Thanks again, Brad.

Re: Wiper Trans/Bubba

The shaft is spring loaded because of the "self-adjusting" cable tension feature. The spring is probably causing the pawls on the pulley halves to disengage since the bottom half of the pulley appears to be loose ( slip fit )
The shaft was peened over on the wiper blade end. The pulley end was pressed fit and also sometimes peened over. Can you peen the end to retain the shaft. If not I think the screw and washer would work. Here is a link to an excellent article on the wiper transmission. It has pictures with a trans. disassembled. http://www.carols62.com/59/wiper_trans.htm

Re: Wiper Trans/Bubba

Erich, I think I will take the transmission out and put the shaft back in then tap the shaft in just far enough to peen the edge and reinstall it, I have some confusion on the procedure of the cable tightening sequence, hook up to the center (motor pulley first?) do these tighten themselve at the transmission by just pushing on the wiper shaft, I don't get the take the slack and wind it around the pulley, which pulley? I think I need a blow by blow of what to do after I put the transmission back in the car on the cable procedure, looks to be pretty simple if someone could show you one time. Thanks,Brad.

Brad,

It sounds like you are ready for a rebuild job. If you follow the outline of what has been shared on the board and the link provided, the job is not bad to complete.

Regards,

Re: Wiper Trans/Bubba

It looks to me that problem is that when the shafts were intalled that the last pulley was not tapped on far enough to stay connected to the spined part so I need to get the shaft through far enough to peen the end of the shaft so it cant come back through the pulley, still need an explanation on the cable procedure. Thanks again, Brad.

Re: Wiper Trans/Bubba

Brad,

When you press down on both shafts, the cable becomes slack allowing you to install the cables. Once the cables are installed, push down on the shafts again to release them back to the normal position.

Re: Wiper Trans/Bubba

Dennis, when putting the pulleys on the shaft by hooking the spring to the upper pulley as noted then the bent end of spring to slot in lower pulley do you just push them together and lower pulley will drop onto the spot that it goes? also my upper pulley is still hooked to the shroud and cable coming out one opening, does the other come out the other opening both without any raps of cable on pulleys, and with a trial run (I did) on bench, by pushing on end is it supposed to recoil? Mine did not. Thanks again, Brad.

Re: Wiper Trans/Bubba

Brad,
Here are two photos of the D/s transmission from my '62. I don't believe '58 to '60 is any different. In the first photo the upper pulley is against the left stop ( tab ). The cable on the upper pulley is all the way around. The cable on the lower pulley is about half way. In the second photo with the upper pulley against the right stop it is the opposite. ( upper pulley 1/2 way, lower fully wound ). The photos are with the spring just installed in the respected slots.
In order for the pulleys to recoil you have to first set tension on the spring.
While pushing on the shaft, pull both cables. You should feel the resistance of the spring. Keep the tension on the cable and release the shaft. The pulley halves should lock together. There is now tension in the spring. If you push the shaft again the pulleys should move back to there original position. I haven't reinstalled my wipers yet but I think it would be easier to set the tension while the wiper transmission is on the bench. Then carefully install it in the car without pushing against the shaft. Once the cables are hooked up then push down on the shaft and the cables should set to the right tension. Erich

Re: Wiper Trans/Bubba

Brad,

Yes, when installing the lower pulley, you can proceed the way you indicated, however, make sure the two pulleys mesh together.

One of the cables may wrap around the pulley about 3/4 of the way before it comes out.

The pictures in the post above look right on.

Re: Wiper Trans/Bubba

Apparently if the wiper motor is stopped in the wrong position you need more cable which isnt there, No. 1 at the motor was tight, had to pull with pliers and push with needle nose to get it over the hump, can you rotate the motor pulley without turning on car and wiper motor? now I have to try the drivers side cause it popped out, might try and just tap the shaft in further and see if it holds, pass side was not peened and was not driven in far enough to stay in anyway, I peened it for insurance, knock wood, Thanks all for the great schooling. Brad.

Re: Wiper Trans/Bubba

Brad,

There is a timing issue when connecting the cables from the transmission to the wiper motor. The wiper motor needs to be in park with the transmissions turned to the park position. If not, the sweep of both sides might not be the same.

Also, be sure to cross over the cables on the passenger side, or you will have that wiper turning down.

Re: Wiper Trans/Bubba

Hmmm, did not know that, what is the park position on the right side, will I have to loosen cables and try again, if so can I run the wiper motor with the shafts removed (Left side), and the right side hooked as I did but not sure on timing or at least take the cables off the right side and the run motor with left side no shaft and right side with shaft in but no cables? Sorry, Brad.

Hi Brad
Send me your private e-mail adress and I will answer it with some pics about Wiper Trans, maybe it would be a help!

Brad,

I would suggest starting with the cables disconnected and verifying the wiper motor is in park. If you are not sure, hook power to the wiper motor and move the control to park the motor. I think there might be directions in the ST-12. Then turn the wiper transmissions to their at rest position.

Since the wiper transmissions do not turn 360 degrees and you want the wiper arms to travel the same path on each side, they need to start from the same position.

After you have the cables in stalled, run the motor without the wiper arms to insure they travel in the proper direction.

I hope this helps.

Re: Wiper Trans/Bubba

Brad,
Just wanted to add an FYI. I measured the travel on my wiper motor assy. out of curiosity and for future reference. The output shaft oscillates in an approx 100 degree arc.
