Lo Boy 154 Transmission Drain Plug Location?

Postby Flatlander » Sat Nov 17, 2018 5:37 pm

Hi all, I''m waving the white flag locating the transmission drain plug location. It's a 1969 154. I guess I'm not looking in the right place? The manual has an arrow pointing to it but I can't see it anywhere. :lost: Any help would be appreciated. Thanks, Bryan.

It’s on the bottom of the tranny housing between the finals.
I'm technically misunderstood at times i guess its been this way my whole life so why should it change now.

I guess I just can't see it. between the finals there is a round flat place in the housing about 3 inches across that looks like a place for a plug , but no plug. Are the finals and transmission using the same fluid? The only drain plugs I see are on the finals. Thank you again for you help, Bryan.

Final drives have there own fluid. My 154 had a 1/8” pipe plug for a drain.

I haven't been around 154s very much. But it seems to me that at least some of them required disconnecting the hydraulic suction line to drain the transmission.

Thanks Jim. From what I can see that looks like the only way to get it drained.

One of my 154s has a drain plug in the round flat spot that you spoke of and the other does not.

Maybe the guy that was supposed to drill and tap these called in sick that day.

Maybe they missed the drain hole. The suction for the hydraulics feeds from the drain hole originally from the fcub. You could grease a drill and poke a hole in the boss. Grease the pipe tap and thread it if it’s missing.

I might try that, thanks.

Or you could remove the plate from the back of the differential.
I have an excuse. CRS.
