Parked position of Vacuum wipers

Post by Wolfy » Mon Apr 23, 2018 6:40 am

Hey Guys,

I've just refitted Trico vacuum wipers, they came on the Jeep when I bought it in 2009 and the position of BOTH the wiper arms when I
bought it was pointing from drivers side to passenger side like this / /

Now I've refitted them the drivers side is the same but the passenger side units wiper arm faces passenger to driver so they look
like this \ / ummm whys that?

Each time I turn the engine on the wipers always reset to this position. I tried taking the hose off moving the wiper manually and
reconnecting the pipe but they just always reset to this position. Can I change this? :?

If I swapped the units around I would get this / \ which is still wrong. arrgghhh! Can anyone help?

Thanks

Wolfy. That is what I call my nephew.
Do the wipers work when you turn them on ??
The secret is a manual shuttle valve that is moved back and forth as the arm sweeps from side to side.
Maybe the shuttle is stuck in one position.
If this is the case, the blade go to one side and stay there.

Hi Mike,

Thanks. The units work perfectly, they turn on and off and carry out a full wipe cycle just fine.

I did remove the rear covers and just lightly grease the moving parts under that cover but assume that has no bearing on ths issue.

Originals are Trico S-583-1 they have a flipper knob on the tin cover side and when at rest, the lower ends face the passenger side. I will try to post photos of NOS TRICO S-583 Wiper Motors tonite. From the description it is assumed that your motors are not a match.

All you have to do is find an S-583 (WO-663636) MOTOR for the passenger side.
do not have the TRICO factory part numbers and applications for JEEP. Ther'res at least 8 or nine different combinations of similar looking TRICOS for MB and CJ-2A thru CJ-5. Some CJ-3B/CJ-5 have Export ventilating windshields and what they fit is complicating.

Your passenger motor is for a CJ-3A,3B drivers side. Look for a motor with the inlet tube on the LEFT as is your drivers side. CJ-2A motor weather driver or passenger is the same as the WWII jeep type.

ok many thanks guys. Finding one over here in Europe is going to be a challenge.

Does it generally follow that the side the tube enters denotes how the unit parks itself?

Also if I find a body with tube on the left is it straight forward to put my mechanicals in it?

CCKW OPEN CAB also had S-583-1 TRICOS. The French army had a locally mad TRICO that is nowhere near correct. The attaching hardware and fit was unsatisfactory in appearance. Hopefully you will encounter an original TRICO S-583-1 from an Open Cab CCKW.
