Fan Pulley and Damper

I am installing a late 14L motor in a Star, Model R. It was necessary to remove the front motor support plate and chain cover and replace these with a timing chain case and cover from an early 14L. The crank on the motor being installed has an OD of 1 7/16" and the crank/fan pulley that I have is the correct size to fit over the end of the crank. However, the attached damper (part number 26225) is too large for the space in the Star. The parts book also lists a damper (part number 26294) used on both Models 55 and 60. Does anyone have one of these and could provide the ID, OD, and thickness of this damper? Has anyone solved this problem in a different way? Is there a "plain" (doesn't take a damper) fan pulley with an ID of 1 7/16"? Thanks for any help.

Re: Fan Pulley and Damper

I'll try a different approach - Does anyone know if all Durant/Star dampers were the same size?
Thank you.

Re: Fan Pulley and Damper

2 and 1/2 years later, I see your post. The damper on the 14L in my car was too big when it was installed back in the '70's, and whoever did it actually cut the sheet metal of the splash guard to get clearance for the damper. I have a spare 15L engine that has the same size damper on it. At present, I am trying to find out what to torque the damper springs to so that it will slip the proper amount, and actually be a "damper".

Re: Fan Pulley and Damper

The springs should be in pockets between the two plates with friction surfaces on their outsides. Shouldn't be any "spring torque" to worry about. Unless you are talking about the free-length before installation.

Torsional dampers were found to be necessary on most six cylinder engines. Otherwise crankshafts break.

Except for a few cars, the Lanchester damper was replaced by rubber or viscous type dampers. Rolls Royce used it for the longest time.
