Fitted New Gearbox To Rover 114, But A New Problem!

[jacobs53 0]

good news all round the gearbox has been replaced, finsihed today at 5pm. A few problems I come across was the gearbox support arm (the one that locates on top of the subframe) the two rear bolts had seized that bad that the captive nuts on the rear had come loose, so I had to hammer and chisel them to release. Another handy tip is to remove the long driveshaft! I thought id be cleaver and leave it bolted to the hub still and just drop it down, but it can't physically drop due to the subframe location. - I may point out that if you have ever worked on a metro there is tonns of space in the engine bay.

 

Otherwise all went well, but I have another problem which I haven;t fixed as yet... After the box was installed and everything finished, I went to drive the car, and basically whats happening as you get the bite the whole car shakes (very simialar to a broken engine mount or loose bolts) Thing that stomps me though is it only happens when moving from a standing start, if your moving the cars fine. I think its a loose bolt (well to be honest im praying!)

 

Anyone ever come across this porblem before?

 

cheers lee

 

p.s sorry I didn't know what topic to put it under, not an XU, or TU.... well uses the same peugeot gearbox does that count?

I really need some advice before I have to take of the gearbox again......

 

I fitted the 4 speed gearbox to my rover on Tuesday, and also fitted a new 190mm clutch pack. Before I changed the gearbox the car drove perfect, with no juddering when lifting onto the clutch. Since fitting the new box and clutch when moving from a standing start the whole car shakes, and judders until I have fully released the clutch. It doesn't matter what gear you take off in either i.e. 1st or 2nd. I have checked all the engine mounts and they are super tight, so I am completly confused!

 

It confuses me because when your moving - even if its 5 mph - the judder doesn't happen, or when you change gear when moving.

 

Has anybody had this problem before? Or anything similar?

did you align/center the clutch when you fitted it?

agree with jack.. sounds like clutch judder

Yea it does sound like either clutch judder or maybe a loose engine/gearbox mount.

god knows what it is... I personally think it is clutch judder aswell, I used a proper snap on allignment tool... maybe it moved while tightening up the bolts?

 

Il have to whip off the box again and re-check

If the clutch isn't aligned the gearbox will not fit. and anyway once the pedal is operated the clutch plate will centralise itself, clutch judder is more likely caused by oil or grease contanination or maybe a dodgy cable. When you changed the clutch, did you wipe the new cover plate face with some thinners and a clean rag? to remove the coating of oil?

After 200 miles the juddering has not improved! There must be a fault with the clutch but I have no idea what!

 

Just replying to markic - I did wipe the clutch cover plate, and I was so careful not to get oil onto the clutch components. I also wiped the flywheel surface face and removed the dust.

 

I have ran out of ideas to be honest, the only possibility in my opinion is that somehow the clutch cover plate has become distorted, and basically has warped, causing a juddering motion. I have already got a replacement clutch to replace this one with, so i might just take off the box and inspect clutch and then replace with new item.

 

Bugger I don't know what to do!

are you sure you didnt damage the driveshaft when you hung the wieght of the gearbox on it? did u check the bottom arm bolts are tight?does it make the same noise if u go into geear with the car on axle stands?

 

as said above, the clutch aligns itself after u operate the pedal. did u replace the 3 clutch parts or just friction plate? is the gearbox a known good box? is the noise heavyer/softer on full lock pulling away GENTLY?

The weight of the gearbox wasn't an issue as I was using a engine hoist when installing the box, so I doubt the driveshaft would of suffered any damage, also it isn't the normal driveshaft failure noise. I didn't undo the bottom arm bolts - hydrogas - I loosened off the top bolt and steering arm then took out the driveshafts this way, and yes they are tight. Havne't tried the car on axle stands, might give that a go.... just to confirm the gearbox doesn't make any noises, it just judders the whole car

 

I replaced all 3 clutch parts - quinton hazel.. The gearbox should be fine, obvesiously its second hand but the only aspect that would cause juddering in a gearbox is a worn input shaft splines, and I checked it and its fine. The gearbox also drives fine when off the clutch, say for instance changing from 1st - 2nd - 3rd - 4th and then back down... Just judders when you have stopped the vehicle, and try to launch again (by the way I have tried launching in 2nd and 3rd gear and it still judders!)

 

The judder is dependant upon where the clutch pedal is, when fully depressed there is no judder or noise, when just starting to obtain the "bite" it starts to judder and it gets worse the more you release the clutch pedal, until you have fully transmitted the drive and then the juddering stops i.e after the biting point.

 

I am really confused by this, as I have replaced over 10 clutches but never known this to happen! The haynes manual states a few suggestions, and they all relate to the clutch itself.

 

Cheers for the help inferno, I really need some sound advice at the minute!

just thought Id let you all know that this is sorted now! The fault was the clutch cover itself, aparently QH clutches are not that good and over 50% are out of tolerance!

 

The cover plate distorsion could be easily noted by using a straight edge!

 

Anyway new LUK clutch and its as good as new!

 

cheers for the advice!
