… this is how I got my vac wipers working, or better, moving, at least for the road inspection next November. Either the gas pump doesn’t provide enough vac or the vac motor is bad. I already disassembled it, got it properly cleaned and lubbed. The seals appear to be good, but the wipers don’t go all the way around. I installed new stiff hoses with brace clamps to minimize leaks, but it did no good.
Then I got thinking about an auxiliary vac source. I have an old air horn electric motor. Of course it only blows air, doesn’t suck it, originally. But I tapped the air inlet, screwed in a brass pipe and hooked a hose to it. Then I installed a brass tee and now the vac motor gets sucked by two sources: the gas pump and the electric horn motor.
This way the wipers go all the way around, but this “thing” won’t work for long, as the electric engine wasn’t build to work for long periods of time, but for short horn bursts.
I know some are gonna say “get and electric wiper”, and maybe I will, but I’m still gonna try the vac canister solution.
Can someone point a build thread on this topic? I only find people that have bought the canisters. I’d like a diy solution, since I’m always on a budget and have recently spent cash on a new water pump (85 for the part and 58(!) for shipping it), plus the body work and paint from the accident, plus the heater radiator recore, and so forth.
Thanks.
