I just bought a older power king its a 51. When i drive the transmiton is kinda growly. Is this noise usual? I changed the oil and it didnt help.

I have never owned a Powerking so I can't say for sure but it sounds like the bearings are getting old an worn out. I know that the Farmall cubs are know for having noisy transmissions due to the bearings after all the years of use.

I would say its probably bearings or the gears themselves. does it make the noise in all gears or does it go away in 3rd? you could pull the top cover of the trans and inspect the gears. for wear.

They are tough transmissions, but they do wear. A rebuilt one is very quiet.

Like said, they are VERY strong transmissions, but the bearing do wear out, and that is your problem.

Likely has or had rain water enter through the top from a bad shifter boot.  If that's the case [and it usually is] the bearings are rusted enough to growl.  Those bearings are common and available through your local auto parts store.   If the gears are pitted deep you will have to put up with a noisey tranny unless you know someone that can cut new gears.   The gears are NLA.

Good Luck.  :wave:

Being quiet in 3rd, the most likely suspect would be the bearng between the input shaft and the output shaft. It is loose rollers inside the back of the input shaft and rides on the output shaft. The second would be the input bearing. This transmission is the Borg Warner T-92 and was used in the Crosley car. The transmission is actually still being produced here in Ohio by Olympic Gear but they're pricey. Good used transmissions are available fairly regularly.

I was glad to read this post. I have a PK that has developed an "angry" front transmission. I'll have to try third gear. I suspect water from the P/O. So if it is not quiet in 3rd gear, then it is likely a gear issue?

Also, I have another dual transmission P/K where the rear trans will not stay in gear. Keeps jumping out. What is the likely issue with that? Thanks!
