Did I just break my gearbox?!

[grogan197]

Whilst trying to measure the runout on my brake discs and thinking I was in neutral I gave the hub nut a spin with a breaker bar to spin the disc as the pads were sticking to the rust. I went to put it in first so I could loosen the brake disc bolts and found it was already in first

All of my gears now act like neutral. So what have I done and how the hell do I fix it?!?

Has your gear shifter gone all floppy? hopefully it's just something thats come off shifter end like linkages, never heard of anyone knackering a gearbox by turning hub in gear. Mine gets left in gear with the handbrake down to slacken wheel nuts so not sure buddy

Does it clunk into gears if you move it by hand, engine off?

The shifter feels like normal, I had a look and the gear selector cables are all in place and I tried selecting gears by moving the selector arm which makes no difference

I don't seem to have much luck with this van

oh no if it's clunking into gear engine off, surely that would suggest drive shaft? I'm sure someone with more knowledge can give a more definite answer though

Does moving the selector allow it into gears but the driveshafts still turn? as if in neutral?

[grogan197]

I just had another look and there is a small change in resistance between idle and it being in gear so maybe it's a problem with the clutch as the wheels are connecting to the gearbox but not to the engine...

Possibly a worn slipping clutch then? was it ok before? seems a bit odd that it would just happen parked up? I'd check slave cylinder make sure it's not leaked fluid and taken air back in or something

[mattt429]

is the selector moving? i think there's a bearing in the turret which is prone to failing

[grogan197]

The clutch is fairly new to be honest so shouldn't be worn. I'll have a look at the slave cylinder and see if anything looks unusual there.

The selector should be fine as I only replaced the bearing, seal and bush a month or so ago.

In that case, could it be worn driveshaft to gearbox splines?

[grogan197]

I just gave the engine a start and there is a twitch of movement on the drivers side wheel when I engage the clutch. The passenger side wheel spins but i'm not convinced it spinning at an consistent speed

just geussing here but if the passenger wheel is spinning faster than the drivers, would this indicate that the clutch Is engaging/disengaging correctly and the problem lies within the driveshaft assembly?

[grogan197]

Yes, that would make sense. I think i'll have a look at a schematic of the gearbox and try and get my head round it a bit better.

[grogan197]

I did a test turning the wheels and turning one clockwise should make the opposite wheel go anti-clockwise but they both go clockwise. I'm guessing that means whatever connects on to the driveshafts in the gearbox has come out of alignment...

Sounds like your close to getting it figured out

Have you actually put it on the ground and tried to drive it?
