buickbonehead Posted July 20, 2011 Share Posted July 20, 2011 Does anyone know where to get replacement gears for the power vent motors. The ones offered in the Riview by Hydroelectric do not fit. They must be for '64 and earlier.thanks rick Link to comment Share on other sites More sharing options...
1965rivgs Posted July 20, 2011 Share Posted July 20, 2011 Hi Rick, Are you sure they wont fit???? I`ve put the hydroelectric gears in `65 vintage vent motors quite a few times??? Tom Mooney Link to comment Share on other sites More sharing options...
buickbonehead Posted July 20, 2011 Author Share Posted July 20, 2011 (edited) Tom:They don't fit....unless there is a difference in the '65 Rivi power vents and the big cars?I thought the Rivi's and the Electras/Wildcats/Impala's were the same.Here are the pictures. Is this motor the same that is in the '65 Rivi?The replacement is on the right. Notice the gear diameter is smaller on the replacement. It is too small to engage the worm gear.The replacement is missing the extended shaft on the bottom.

Dales90 Posted July 20, 2011 Share Posted July 20, 2011 Hi,You may want to remember why the original gears would fail, they were made of pot metal for a reason, so they, rather than the steel worm gear on the armature shaft of the motor would not.GM would rather have replaced the cheap gear than a motorl.I would be concerned about the gear being of same or harder temper than the worm shaft gear.years ago I purchased remaining GM inventory of the original gears. There were just 5 passenger and 4 driver side gears in the whole gm parts inventory. They cost me $15 each, those were the daysDale Link to comment Share on other sites More sharing options...
1965rivgs Posted July 20, 2011 Share Posted July 20, 2011 Hi Rick, Your motor is a `66 and later version which is quite different than the `63-`65 Riv motor. I assumed a `65 big car would use the same motor as the Riv but in hindsight the `65 Riv was based on the earlier models so Buick may have used different vent motors for other models. Do you have a `65 Buick parts book? Do you have the right motor for your `65 big car? Tom Mooney Link to comment Share on other sites More sharing options...
1965rivgs Posted July 20, 2011 Share Posted July 20, 2011 Checked the `65 Buick parts book...the big cars and Riviera used different power vent window gears....time to call your machinist buddy!! Tom Mooney Link to comment Share on other sites More sharing options...
buickbonehead Posted July 20, 2011 Author Share Posted July 20, 2011 I guess I owe Hydroelectric an apology! This motor does fit my '65 Wildcat. I have several sets of these. Fortunately two sets have the full range of motion. The gears are still a little worn but I wanted to replace them since I was this deep into the doors.I recall seeing some motors stamped '64 and '65. I don't know if those were date stamps or not. I'll try to post some pics of those. I guess the big cars switched over sooner than did the Rivi's.I've heard the power vents were not offered on the Wildcats. I've only seen them on Canadian built Cats. Thanks for solving the mystery for me Tom. I guess it's off to ebay with these repop gears since I've had them for more than a year.Regards,Rick Link to comment Share on other sites More sharing options...
1965rivgs Posted July 20, 2011 Share Posted July 20, 2011 No vent windows period on the Rivs from `66 and up...you are correct, power vents on the Canadian built Wildcats only, not the U.S. versions....I`m currently installing power windows and vents from a Canadian parts car on my `66 Wcat driver...who would order a convert with crank windows!? Ugh...Another "interesting" fact regarding Canadian built Buicks...the Canada Salesman`s Manuals identifies the "Super Wildcat" as the SINGLE 4 bbl 425 unlike the U.S. versions which use the term to refer to the DUAL QUAD 425. Go figure.. Tom Mooney Link to comment Share on other sites More sharing options...

Guest czr66 Posted August 20, 2011 Share Posted August 20, 2011 Rick did you replace the gear with the longer shaft? I can't seem to find a replacement for that one. Link to comment Share on other sites More sharing options...
