1952 TEA 20 - sticky gear shift action

Hi again gang -- just wondering how the shift linkages under the cover get lubricated. Does the hydraulic fluid get up there somehow?

Lately i've been having real trouble engaging 3rd, 4th, and Reverse. No grinding or anything - just lots of drag on the lever, and sometimes I can't move it at all toward any of those gears til I give it a lot of running between N, 1st, and 2nd.

Eventually, after some driving things improve but the other day I nearly got stranded nose into the garage!

I'm going to try to get in there but before I just slather grease on everything, should I be looking for evidence of some internal lubrication? I guess it's also very possible the guides have worn out of spec and something's getting hung up. :(
 

No lubrication at all except for the odd drop of oil that might slash upwards when you hit a bump .
The reason it gets easier with work is that the guides are expanding as they warm up and allowing a little more clearance .
The gearbox cover on the TEA doesn't come off by itself like the TO :cry: . The easiest way is to take off the gear stick , two nuts and a bit of wriggling and lubricate the slides from there . Sometimes a decent squirt with engine oil from a flexible nosed oil can will be enough to free it up .
It isn't that uncommon to find them stuck completely after a Winter's lay up .

Ho boy - that looks like a couple hours work.

Thanks for the advice, Charles. Definitely going to try the gear lever removal and oil squirt first!

Cheers.
 
Splash lube keeps it happy enough. Before you, uh...tear off that cover, how about a clutch adjust? Yeah. in a normal car, hard
shifting can be traced to a clutch out of adjustment at times. Your tractor is not a car? Wanna bet?
It just goes a tad bit slo-ower.

Sensible advice there - I will check it against the specs
I think I remember reading here from John (UK). I just assumed all gears would be a tough go if the clutch was out of whack.
 
Nope. Usually first and reverse I have also had problems with getting to high gear with a bad clutch. I have also cheated
by placing in gear and then starting the engine with foot on clutch. I have started in gear with foot off clutch. Hope you
got a good battery for that trick. I can also shift without a clutch, Not recommended due to excessive wear on the brass
syncro's in the trans. Downshifting with no clutch can also be fun. Remember syncro's? They hate that even more.
How many transmissions have I torn up? Well there was that Power-glide that was fun. . . Not suppose to slap reverse when
at 45 MPH. First time was a mistake. Second time ??
 

That is a TEF tractor Tony . KiGass starting system , same as used on Spitfire fighter aircraft and a decompression lever for starting .

I have found that like heavy equipment, sometimes to slightly clutch it enough to sort of giggle the gears so they no longer bind internally, frees it all up, espesially when the drive train is under some load.
