David Brown 1190 gears

[Kylemcnamara]

Hi I have a David brown 1190 but changing gears can be a struggle and more often than not I'm stopped before I can change gear. I think it's a synchromesh gearbox and changing up the gear can often end up in gears grinding. Does anyone have an idea?

Lot of DB gearboxes had synchromesh on second and third gear only. Have you checked that the clutch is operating properly, an adjustment on the slave cylinder linkage. Maybe it's clutch drag?

As above synchro between 2nd and third

 

[Kylemcnamara]

I will check those things listed. What does the synchromesh mean on the 2nd and 3rd gear. I don't completely understand it. Thanks

 

[Kylemcnamara]

Another question. Is the 1190 and 1290 gearbox the same or is it same for numerous models or just the 1190

We had a 1390 that went hard to shift gears cleanly like yours and it was the thrust bearing on the clutch

 

[john432]

Think the 1190 was based on the 885, being a smaller 3 cyl tractor, the 1290.developed from the 990.

There is syncromesh on 2nd and 3rd gear only, should be very smooth to change
If you are referring to having problems with changing either of the short gear levers on the left they have no syncromesh and not designed to change on the move

Thanks. Was it a big job do you know?

Thanks for the reply. So if that's the case you should be completely stopped and take off in 2nd gear and move into 3rd. Basically meaning yo shouldn't change from 1st to 2nd on the move? Is that correct. Thanks

Do you know if the gearboxes are the same. Thanks

You can change to second or third while moving no problems, should be very smooth, you can also change down to first while moving, but not so smooth, and a bit of a crunch perhaps but that is fine

They probably are the same

This is where my problem is, it doesn't change smooth and crunches or grinds changing gears but only on the move. It won't crunch or grind when stopped

The 885 and 1190, or the 1190 and 1290?thanks again

Syncromesh problem
Big job unfortunately

11 and 1290 probably similar but I'm not certain

Would it just be easier try and get a gearbox?

Maybe, but you still need to remove the cab and split the tractor 2 places

Would the tractor also need splitting in 2 if I was to try and fix the synchromesh
