L Series 4 speed to 5 speed.

[C.Randall]

I have bought a 5 speed short box to go behind an L14 in a 140j. I was hoping it would all bolt up but cant seem to get the drive shaft in the 5 speed box?? Whats going on?? Will there be anymore things I need to change? or should the rest be fine, all mounts seem to line up okay..

Which 5 speed do you have?
There are two different lengths for the L series gearboxes. The 710's need the short series gearbox. 180b's, bluebirds, and 200b's used the longer series.

I have the short box its just the drive shaft wont slip in the gearbox all the way like it hits something..

Is the shroud on the input yolk fouling?
Some inputs have a different shroud to others.

Someone else had this problem not so long ago although it was on an A-series, can't remember, may have been Beaver in Wellington? I think? I am sure for them it was a build up in the splines, not sure if the box or the drive shaft was to blame. If the splines line up you may need to have a look at the splines, give them wee clean then see if you can slip it on further.
Good luck

I have a selection of different length driveshafts for sale that suit L-series gearboxs.

Did you also slam it at the same time?
Sometimes when fitting lowering blocks, the axle can move forward as it moves up. I had to reshorten my D/shaft when I fitted blocks.

Thanks all, I know the splines match so Ill see what condition they are in. Only problem is my 4 speed has a horrific whine and is undrivable..
