Gearbox support

I seem to have lost the gearbox support spring and associated bushings. Anyone know where I can buy these parts, or does anyone have any 2nd hand bits I can buy? The weight of the gearbox is now supported on the snub rubber, which now looks pretty ruined. I assume pressing in a new snub rubber is a gearbox out job, or at least removal of the tail housing.



Cheers, Tom

You might be able to get the new snub rubber in if you make yourself a remover/installer using a bolt and washer pulling into a socket or similar. If not the housing comes off pretty easily.

The rubbers should be available from the normal suppliers, but the special washer for the bottom and the spring are probably only going to be found secondhand. I may have the spring, it's possible I have a washer as well, but if the washer isn't with the spring, then I've got no chance of finding it........ I'll try to have a quick look tomorrow.
 
Thanks for that Harvey.

Failing being able to source any replacement bits, I wonder if I might be able to make up an alternative using a readily available rubber cotton reel mounting. I could fabricate a new angle bracket for the back of the gearbox, and make a new support beam to pick up on the existing mounting points on the base unit.
 
I have the spring, but as I suspected, there's no sign of the special washer it sits on. It came from an auto but I have no reason to think it's any different to the one on the manual, but if you wanted it you'd have to satisfy yourself it was correct by reference to the parts manual, which I don't have for a 2000/2200.
 
Thanks, how much do you want for it?

I have the parts manual at home, so can cross reference the part number there, though I won't be home for a week to check. I can probably turn up a suitable washer when I have all the other bits.

Cheers, Tom
 
Cross reference the part number in the parts books, (providing the books are of similar years) and if it is the same send me a PM and we can sort something out.
 
Wadhams has a kit of the rubbers and spring. But one of the rubbers is not quite right, you have to cut a hole in it for the special washer, which is not available.

The spring is a different part number for the automatic versus the manual. Looking at the parts book the spring for the automatic looks heavier than the manual one in comparison. So an automatic spring might work okay on a manual, but not the other way round if you have no other option. The auto box would be a heaver box I think.

Thanks for confirming, I had no way of checking for certain.

Would they really be that helpful?

I'm pretty sure the one I have is from an auto, so it will be up to the OP to make his own decision on that.

I'd agree with that.
 
Thanks for looking Harvey. I'll see if I can get hold of the correct parts first, but will get back to you if I can't find any. Rover obviously know a thing or two about noise, vibration and harshness if they specified different springs for different gearboxes.

Cheers,

I can probably get something turned up at my local machine shop if I have the spring, rubber washers and adjuster stud to measure off.

I think my mount went awol because the rubber bushings deteriorated. The bushings are required to locate the spring on the gearbox bracket. Being perpetually coated in oil has caused them to soften to the point where they fail. Without the top bushing, there's nothing stopping the spring slipping out sideways as the gearbox moves up and down. An oil soaked snub rubber probably allows for more up and down movement too.

Cheers,

Tom

ISTR there's a boss on the tailshaft housing that would stop the spring moving sideways.
 
I must be missing something else then. I only have the sheet metal bracket with the hole in, as per the photo.

As you were, my mistake, I was thinking of the auto.
