Guest JDHolmes Posted September 25, 2006 Share Posted September 25, 2006 HELP! This is the last item to get working correctly til the beast is inspected and on the road. Windshield wipers...55 Pontiac wagon, vacuum wipers.There is an vacuum inlet from the fuel pump which is identifiable. however, in the center of the motor, there is another fitting which is open. I've closed it off with some hose but the wipers barely move (1/2"). Does this fitting get vacuum and if so, from where.I've checked my 53 which doesn't have the second fitting. I've checked 53, 55 and motor's manuals but none even picture the wiper motor so I'm here.*** editI've fixed it. I removed the plug and they began working, a bit of lube on the cable and they work like new. I guess the second fitting is an exhaust fitting.ThanksJD Link to comment Share on other sites More sharing options...
Guest De Soto Frank Posted September 26, 2006 Share Posted September 26, 2006 JD,My guess is that the second fitting is the exhaust too...My '54 Chevy pick-up used a large wiper motor than the '47-'53 Advance Design trucks, and the '54 motor looks like the one GM used through the end of their vacuum wiper days...I've seen illustrations of Trico vacuum wiper set-ups circa 1940, with the three-way vacuum valve and two hoses to the vacuu, motor... I think one hose was for running and the other was for a park-position ?Good luck on your inspection ! <img src="http://forums.aaca.org/images/graemlins/cool.gif" alt="" /> Link to comment Share on other sites More sharing options...
Fred Zwicker Posted September 27, 2006 Share Posted September 27, 2006 Why not call Rob Ficken (of Ficken Wiper Service)? See wiper info. Rob has been rebuilding Trico wiper motors for years. When Trico closed operations, his dad purchased all of the replacement wiper motors, parts and tooling from Trico. He just furnished a NOS wiper motor for my 1939 laSalle and it works great! Rob is in West Babylon, NY and can be reached at 631-587-3332. He will also be at Carlisle and Hershey this fall. Rob is probably the final authority on Trico wipers and should be able to tell you whatever you need to know.Fred Zwicker 1 Link to comment Share on other sites More sharing options...
Guest JDHolmes Posted September 27, 2006 Share Posted September 27, 2006 Wow, thanks Fred. I had no idea. Mine are working fine now, but this type of information is gold, solid gold. Link to comment Share on other sites More sharing options...
Guest wanikkan Posted May 22, 2011 Share Posted May 22, 2011 Is there any chance of locating a diagram to my 1940 Plymouth Trico windshield wiper motor? Link to comment Share on other sites More sharing options...
Rusty_OToole Posted May 22, 2011 Share Posted May 22, 2011 When you have a vacuum pump on the fuel pump the vacuum hose is supposed to go from the wiper motor, to the fuel pump, and then to the intake manifold. The pump itself should be marked in and out, or wiper and engine.Normally the vacuum pump is held open by engine vacuum. Only when the engine runs out of vacuum, should the pump kick in.

I am doing a restoration on a '54 Buick with vacuum on the fuel pump and think that the above would apply, but am not sure. Thanks,Fred Link to comment Share on other sites More sharing options...
Rusty_OToole Posted May 22, 2011 Share Posted May 22, 2011 Does the vacuum pump have 2 hoses to it? If so I would assume one goes to the wipers, the other to the manifold but you would have to check your factory repair manual to be sure. Unless the hose fittings are labeled.

Fred Zwicker Posted May 22, 2011 Share Posted May 22, 2011 Thank you Rusty,I am almost certain that there are two hose connections on the fuel pump. Fuel pump is at work, so don't know if each vacuum pipe connection is marked. I just had the fuel pump rebuilt by Arthur Gould, so in a pinch could always call him if information is not in my repair manual, which is also at work. Thanks for the help. Sometimes a simple thing can easily become a big problem if something is missed.Fred Link to comment Share on other sites More sharing options...
Guest wanikkan Posted May 22, 2011 Share Posted May 22, 2011 The vacuum line from the intake manifold on a 327 chevy runs to a reserve tank that is round, black and a little larger than a soft ball. The odd shaped T connection accepts the line from the manifold at the bottom of the T. The left side of the horizontal T is connected to a short hose that inserts into the round, black reservoir. The right side accepts a hose that is connected to the Trico vacuum windshield wiper motor. There is only one hose, meaning one connection on the Trico motor. I have vacuum at the motor. My problem is with the inner workings of the motor. I took it apart to clean. It was dirty and the grease was hard. On the bottom side of the motor is an odd shaped cover held on by 2 small screws. The cover is pointed at one end and has a raised circular cover at the other end. Under the cover is a thick felt bushing, a gasket with a very small spring attached to it, a small aluminum piece that looks like a headless man with has arms and legs stretched out and a hole through his belly as big as his mid section, a round weight that inserts into the the rod that holds the vacuum arm that flips back and forth in the vacuum motor chamber and attaches to the windshield wiper arm connections that cause the windshield arms to go back and forth on the windshield. There is also a flat piece of steel metal shaped like a small paper clip with rounded ends. At one end there is a diamond shaped hole with a small piece of metal extending down as if to hold it in place. Below the diamond shaped hole is an elongated rectangular hole running the length of the clip. The hole is rounded at the round end of the clip and flat just below the diamond shaped hole. What happened was, no sooner then I had removed the small cover, I dropped the entire motor on the floor, leaving me with multiple parts from unknown places. This is why I am wondering if there is a source for a diagram of the inner workings of a Trico windshield wiper motor for a 1940 Plymouth. Like I told the piano teacher, my hands fit a pipe wrench, not a piano. If no one can be of help, I will call Rob Ficken to see if there is a remedy to my dilemma. Thank you for your concideration.......... Link to comment Share on other sites More sharing options...
1957buickjim Posted June 1, 2011 Share Posted June 1, 2011 Wanikkan, pictures are worth a thousand words...perhaps posting a few would bring some of what you are encountering to light to the forum watchers and fixers..just my thoughts,Jim Link to comment Share on other sites More sharing options...
Guest wanikkan Posted June 11, 2011 Share Posted June 11, 2011 1957buickjim, Sorry for taking so long to get back to you. My computer is so old, I don't know if you can hook a camera up to it............also, I don't have a camera that works with a computer. Anyway, thanks for the thoughts just the same..........
