Hi,
Did a search and didn't quite find the info....
Had the LJ track car out at an event today.
1st run, lap 2...gearbox dramas.
Here's the story....any advice appreciated. Obviously we will pull the box out and have a look tomorrow.
Gearbox was replaced recently with a newly overhauled box with XU1 ratios. Has been street driven several times after box put in, just to check stuff etc with no dramas.
I did notice that 1st gear was sometimes not easy to select, even when stationary.
Out on the track, lap 2 and when going up from 2nd to 3rd. had to have a few goes at it to get third?, a few corners later same again?.....then within a few metres, engine started to struggle / die , clutch in, rev it ok, but by now the gearbox started to feel like i was seizing up ( not the selectors, but the actual drive). Rear wheels locked up and skidded to a halt in the middle of the track.
Fortunately no one ran up my arse.
Tilt trayed off.
While being pushed back into garage, with the clutch in, there is a pronounced metallic grinding noise from under the car, however it sounds external to the box.?? With clutch out, rear wheels are locked.Jacked up rear, turned wheels back and forth by hand with clutch in, and Locker diff feels normal.
Looked under car and flywheel etc look good and in place.
The gear selector moves around, but wont actually select a gear?
Back home and up on the hoist, all looks normal underneath, engine starts and revs fine, clutch is working, can see the fork moving etc.
Tailshaft looks normal.
I think I have heard about these boxes having an issue where 2 gears are selected at the same time, and thus they lock up...but I always thought that it was a 1st and Reverse issue?
Any ideas?
Thanks
