Gearbox Cruching In Reverse

[kma]

This may be a stupid qustion, but this is my first manual car.

When shifting into reverse it seems to crunch unless the car in at a stand still. Is this normal?

I thought as long as the car is in neutral i can shift into reverse?

Thanks

I've found with alot of imports you need to double-clutch reverse as it doesn't always go in first time. I'm not sure if this is normal, but happened with 3 of my 4 cars

yes, there are no synchros on reverse (and I think it is straight cut too?) It can be tricky to get first time sometimes, just let the clutch out in neutral then clutch back in and try again

^ yea what he said. reverse has no synchro so you must be stopped completely to engage it.

sometimes yea it will seem to not engage even though you've stopped, and often its just that your unlucky and have stopped right at the point where the teeth lockup against each other and wont mesh. if your on any sort of slope, let the car roll half an inch in either direction (or use 1st gear if on level surface and cant roll) then stop and try again. tends to work every time for me.

ive also noticed in some of my cars that are a bit older and start doing this more frequently when the gear stick is at the point where it locks up going into reverse you can get away with letting the clutch out only just enough to kick the input shaft around 1/8 of a turn while you have light pressure on the stick pulling back into reverse and you'll find it slots straight in. carry on

if reverse has no syncros, does that mean 1st doesnt either. when im slowing down to a traffic light i try to put it in first gear while im still rolling and it crunches. so im thinking it doesnt have syncros either??

Well if it was nineteen sixty soemthing & you were driving an MG then the chances are the gearbox wouldn't have synchros on either first or reverse. But being a vaguely modern car it does atleast have synchros on first.

when crunches into reverse, i think its your clutch that is worn

If ti crunches in reverse your clutch is dragging, not worn.

Dads freelander does this.... Clutch is newish. Just solve it by going into first then back into reverse - always works but is annoying.

Yep, or spigot bearing

to engage reverse properly always select a further away gear first. Obviously 5th wont let you into reverse, yet if you select 3rd then 4th before selecting reverse you will get it in without the crunch.

My procedure: Stop, select neutral, shake stick, select 3rd, select 4th, select reverse.

Works every time in all 5 speeders.

Dilmah, dooo try it.

djr81 you mentioned something about a clutch draggin?

I have a kinda scraping noise (very light but still) when the clutch is out in neutral... bearing or dragging clutch?

Dunno simply because I am not psychic. If I had to guess I would guess bearing.

hey i tihnk i have the same issue, slight noise when out, when clutch in noise goes away, only very feint though, so id like to know what the go is with this to

[ARTZ]

I think its the throwout bearing , mine does it too, mechanic said dont stress, so i dont...

However when it starts making a scraping noise when you let clutch out slowly in first, its on its way out..

My ute started doing this on thursday

or if you have a aftermarket clutch it could be rollover noise?

this

stop trying to smash reverse while your still moving, unless your doing motorkhana or something theres really no need

clutch up in neutral noise is usually input shaft bearing

clutch in scraping noise is usually thrust bearing
