Gear Box Help plzzzzz!!
Turbo Mini Forums

After the gear box was rebuilt, it went into gear fine. ive connected the rod to the box, clevis pin in, clutch bleed etc.
But i cant select any any gears
Really hope it something simple ive done wrong..
Any help would be great :)

Cheers lads.. :)

This is an old pic before it was put it.. Should it be this way round, as ive just looked and ive got it the other way round ?
Could this be the problem.
Cheers..

Shit Happen's

yes should be as in the pic.

Lol Noob i am... should of checked that.
So i hope that sorts it..
Another thing. im now trying to get the clevis pin thing out again, and my brother said the pin only comes out one way, this correct ? as before a pain to get out, with not alot of room to bash it out..
U live and learn.
Cheers m8

Mine was slighty stiff after a rebuild was the forks that the bell crank lever runs in I think its called, The bits that move the selectors. i took them out cleaned them up with a file to remove the burrs and put them back in! seemed to sort it. Also i used lots of gearoil when building the box up especially on the baulk rings as thay were tending to stick to the gears when torqing up the shafts!

Shit Happen's

i wouldnt drive it as if it is something more serious than it just needing to free up such as something has fallen in/gone in wrong and jammed it up then it could mean another more expensive rebuild!

just driving a little forword will damage something ??
I called the guy who checked my box about it, and he said just drive little forward to move the gears around, and that should help free it .. hmm ?
cant really see anything falling off ..
it was tight at first with box out after just rebuilt, and once in the gears, it lossend up... it's has happend again, freed 1st, and freed 2nd. but just not 3rd and 4th as u know.

So hopfuly the main man richard could tell me his magic

well are you trying with engine running or stopped, if it selects in all gears with engine stopped but not when engine running then check your clutch throw.

also have you any oil in the gear box if it hasnt got to the engine running stage, as this will help no end, but should go into to gear nice and easy but may be a bit notchy at first if you have fitted new baulk rings.

well you should be able to get all gears easily then with out engine running, if you cant get all gears with out it runing then dont start and then try as it may damage things.

try this, jack up one wheel , and in neutral spin wheel this will spin the main shaft and lub up the rings,

also unattach the gear change at the gear box and make sure the stick moves freely, whilst unattached you should be able move the selector rod clock wise and anti clockwise whilst in neutral.

Hello rich..
Ive taking the rod away from the selector rod. and that is ok whiles moving clock wise and anti clockwise in neutral.
Ill try the wheel spining part once ive finished putting the discs back on.
making me well nervous lol

just a query did you remove the bell crank levers when you stripped the box down mate.

First,
When you say "It was little tight going into gear like i said after the build, but once in gear, it was alot easyer." what do you mean ??? What was "a lot easier"? The selector ?? Turning the shafts ?? Or what ??
New baulk rings installed with no lubrication can certainly cause drag between input/lay/output shaft if that's what you're trying to turn, but should not cause too much of a problem selecting any gear in a STATIONARY gearbox.
So, if it's turning the shafts that is stiff (irrespective of which gear is selected) I would look to the baulk rings or any other part of the bearings etc. being wrongly assembled, BUT, if it's the selection that is stiff, and you had the bell cranks apart, I wonder if the "claws" between the bell cranks and selector shaft forks have gone back together right.
It is very easy, when disengaging the interlock mechanism (in order to lock the gears to undo the big nuts) for one of the claws to drop out of the bell cranks so leaving the selector rods in the wrong position when you re-assemble.
Hard to explain without a photo (I may have one somewhere) but could explain a selector stiffness problem, rather than an input/output shaft stiffness problem.
Hope that makes sense.

Rod.

Schrödinger's cat - so which one am I ???

well mate its not looking good, you should always use plenty of oil on thew baulk rings as the can drag on the gear cones causing the box to lock up.

but i have never had a problem, as retired said you shouldnt have no problem getting into gear on a stationary engine, somthing not right some were.

but get her started and see if she free up a bit.

but dont try and put her into gear whilst the engine running, turn her off then try.

have you filled the engine with oil yet?
