Whining Transmission

Postby gjpgonzo » Thu Apr 06, 2017 7:02 am

I have a 1952 McCormick Farall Cub, any idea what would be causing a whining sound while moving?

Does the sound change with gear or rpm? Only makes noise while moving? That will help narrow down whether it's something on the input side of the transmission, within the transmission, or between the ring/pinion and the final drives. Have you flushed the transmission and refilled to the height of the pipe plug on the side?

Not sure, She is asleep up in Maine. Noticed the noise in the fall. Wanted to know what to look for. Thank you very much for the reply.

I would pull the shifter cover and have a look inside if you've never had it off. Things that can make a transmission whine: chipped/rusty & pitted gears, low or no gear oil condition, bad bearings, improperly shimmed pinion/ring gear. If you pull the shifter cover, you will probably have to replace the gasket or put down a bead of RTV sealant. Remember that these use straight cut gears and will make a little noise even if in pristine condition.

My 48 has always had a slight whine in 2nd gear.
I did some work on a friend's 53, and the same thing in 2nd gear.
Not severe but you can hear it. I've always assumed it the nature of the beast. Anything but 2nd gear and I would worry.
Why is there never enough time to do the job right, but always enough time to do it over. :?:
