Cutout fender rear siren

#1

Post by dontsink » Thu Nov 20, 2014 8:31 am

Hi Guys,

I have a special question today. My 57FL was formerly a police bike and has the cutout for the siren on the rear fender. Unfortunately the siren was not with the bike, so i want to install an aftermarket siren. But the one which was originally on the bike is not available at the aftermarket. It was the one which was mounted on the primary and not on the frame and the foot pedal was connected to the siren with a rod and not with a cable. It´s described in the palmers restauration book. First question: Was the cutout at the fender always at the same position irrestpective of the siren used?- if so i could use the aftermarket siren mounted at the frame which is cable operated. If not - any idea where i can get the original siren with all the mounting parts and the pedal?

Thank you!

Thomas

I believe the siren cut-out was in the same place for all rigid frame rear fenders.

Thomas,
The siren for your bike does not mount on the primary. It mounts to the back of the transmission plate.
They show up regularly on eBay, and are illustrated in the parts books.

Thank you Rubone,

Just thought the siren is mounted to the primary because i´ve just seen photos of it mounted. So i hope to be lucky to get one somewhere (maybe on ebay) with all the mounting stuff.
On the other hand, if the cutout ist also right for other sirens, then maybe an aftermarket would be fine too. Althought i would prefer the original one.
I´ll keep an eye on!

Best regards
Thomas

As i am not shure if the cutout fits other siren models than the original one iám going to close the cutout, the welding and painting job is imminent.

As VPHD said, the cutout is the same location for all model sirens used on Rigid Big Twins with the exception of the right hand mounted type used exclusively by the CHP and LAPD in California. The model of siren doesn't matter.

Thank you Rubone,

Then i´ll leave the cutout where it is - an maybe sometime add a siren.
