Replacing an oil slinger on a flathead pulley?

[Kevin Lee]

Bought a truck pulley to finish out the front of my flathead and the oil slinger is in bad shape...okay it's completely gone. It was cut off but it's a nice straight cut and the rest of the pulley is perfect. So I would assume someone makes a replacement that you can slide on before the pulley? Don't certain later motors have seperate slingers/pulleys anyway? This is going on a late Merc - it's most likely a 52-53.

Grim, I don't recall the early or late motors having a slinger as part of the pulley, unless some pulleys have a dust shield. The only true slinger I know of is a tin one inside of the cover thats about 3/1/2" in dia. Any slinger thats on the outside can only be a dust ring. If anyone else knows different tell us.--TV http://www.jalopyjournal.com/ubbthreads/images/graemlins/cool.gif

You mean the sleeve thing about an inch long with grooves? If so, it's a separate piece on about 1949-early fifty engines. I should have a few over in the logpile of Merc cranks. What pulleys are you using--late, I think?

Which part?

I guess I mis-spoke. I did mean the grooved piece - 6359. The pulley I have looks like 6312 in the same pic but you can clearly see that a part was sawed off. I thought that piece was integral on all "truck pulleys". Probably another instance of "39 trans" and "40 juice brakes". I should know by now to always check the flathead drawings page first. Thanks. My seal should be in good shape - no leaks and the motor is holding oil right now. Just pull the narrow belt pulley and trim or space the new pulley accordingly. I'll find out more when I get home and can get the pulley off. Thanks for the help Bruce and TV.

Wide and narrow pulleys were both made with and without that piece attached. I found this out the hard way, working in a very dim garage trying to put a wide integral pulley onto an engine in my '48 with the separate piece in there. I struggled most of a day, I think, and then pulled the timing cover and discovered that little sleeve. I was in college--the art department never saw its hacksaw again.
Someday I'll contribute $10 to Dickinson College, and have a new hacksaw named after me...

Haha. Nice story. Looks like I finally have my pulleys sorted. Too bad we only have two or three big swaps a year. I found some really good stuff this weekend.
