Guest Matthous Posted September 29, 2016 Share Posted September 29, 2016 I'm trying to remove the squirrel cage blower on the front of a 32' Franklin inline 6 air cooled. There is a nut on the crank shaft against a fiber disk brake. I cannot tell how to remove the nut because there are no threads showing. The nut is on a hub made for a hand-crank if the engine is to be started with one. Has anyone on here seen this large 2-3/16" nut and hub on one of these 4-door Franklins?

Guest Posted September 29, 2016 Share Posted September 29, 2016 (edited) I don't know about Franklins but many of the crank nuts can be removed with an allen wrench. Most of the GM ones needed a 3/4 allen key. You might get quicker and better response if you posted this further down on the "Franklin" forum. http://forums.aaca.org/forum/59-franklin/ Edited September 29, 2016 by Guest (see edit history) Link to comment Share on other sites More sharing options...
Spinneyhill Posted September 29, 2016 Share Posted September 29, 2016 What did the squirrel do in that cage? I have not seen such a thing. Or do you really mean something else? Link to comment Share on other sites More sharing options...

Or do you really mean something else? The "squirrel cage" is the large shroud on the front of the Franklin engine. It directs air up over the air-cooled cylinders.

Guest Matthous Posted September 30, 2016 Share Posted September 30, 2016 I think I know the procedure now. The crank hub for hand crank comes off with a special tool then the nut comes off behind it. Only question is if it is right hand threads or left hand? Link to comment Share on other sites More sharing options...
Rusty_OToole Posted September 30, 2016 Share Posted September 30, 2016 (edited) Spinneyhill in case you are not kidding ..... a squirrel cage blower is a type of fan. It is shaped like a drum with fan blades around the periphery. Usually seen as heater blowers or air conditioner blowers in cars, some air cooled cars used them for cooling notably Franklin. with housing. If you owned a home heating furnace you would know what one looked like. They don't have furnaces in Australia do they?

Spinneyhill Posted September 30, 2016 Share Posted September 30, 2016 Thank you Rusty. So it is a centrifugal fan. In my defense, we have no native rodents (only introduced ones) and NO squirrels. I have seen on TV rats and guinea pigs in running wheels similar to that. Oh dear, more jargon. Makes it hard for us unlucky ones in far-off lands. Oh, Tauranga is in the Bay of Plenty in New Zealand. Australia is about 3 hours to the west in a jet. We rejected union with them in the early 1900s. We do have furnaces but not often for home heating in this part of the world. Link to comment Share on other sites More sharing options...
Rusty_OToole Posted September 30, 2016 Share Posted September 30, 2016 (edited) Ha ha ha if you lived in Canada you would be very familiar with squirrel cage fans and squirrels too. Every house has the former and every tree the latter. That is why I thought you were making a joke.
