Gearbox rattles above 55

Post by 80s-new-man » Tue May 21, 2019 9:31 pm

Hi there,
I have a 2.8i with a cossie Scorpio 2.9.
I’m not sure what exact type of 5 speed it has, but anything over 55 and gearstick rattles quite badly.
If I put my hand on, it quietens it somewhat but I feel the vibration.
Does anyone have similar experience?
I’m thinking it could be a gearstick bush?

Cheers, Stu
Cheers

A bush might partially cure the vibes but I would be thinking more of the cause rather than covering it up, and with that in mind I'd be having a good look at the drive shaft for lost Ballance weights or damaged/worn Universal's or centre bearing ,or the tail shaft bush in the back of the gearbox. The fact that its road speed related suggests that the fault is after the motor and the driveshaft area is usually the culprit in cases as you describe

This is, I think, a common problem, occurring at the speed you mention. Most likely it`s the nylon `saddle` that sits on the end of the selector rod and onto which the fork on the gearlever slots. This is only plastic and if worn allows just enough play in gearlever for it to hit a resonance. Just clips in place, easy fit, couple of quid on ebay.

Also, packing the cavity into which the gearlever fits with a thick grease will help dampen it and stop vibration - this is easiest cheapest and quickest if you wish to try this first.

edit:
(All above is assuming it`s a type 9 not the MT75 or whatever the later type was called?)

Cheers Steve
Sounds a bit similar to other cars
Is it easy to get to? I guess from the top after removing all the console etc?

Hi,
yes, it`s just 3 torx headed bolts and the lever pulls out. You may need to use long nosed pliers to get hold of saddle, but other than that it`s a simple job. Definitely pack it with grease while you`re there, as that alone will damp out `buzzing

Thanks Mctool, that’s a good reason for sure..

Steve, thanks, I’ll buy the part you mentioned, as a first port of call... if no joy I’ll go and have the drivegear checked out by my local garage. Cheers! 🍺

Hi there I got the plastic saddle mentioned by stevemarl
However I’ve heard there’s also a heavy duty version.
I saw this on flea bay ...is this the one?

Item

It’s 22 quid rather than 3.50 so I’m not sure..

I'd assume the cheap one will do the same job, but maybe wear out quicker.
So, if it were me, I'd fit that one first and see if it cures it. If not, then maybe you have another issue, but you've saved yourself the £22.
If it fixes it then pick up the HD version for the inevitable change further down the road.

That looks exactly the same as the standard part to me? I believe there are brass`heavy duty` ones (Caterham used the T9 perhaps they offered them?) but I wouldn`t think they`d help with vibration cf a plastic part. I`d do as Martin suggests and put the £3.50 one in, if it solves the problem you know your options. (And pack the cavity with thick grease, that alone will dampen vibrations.)

If you really want one, Burton sell the brass part.

Tommy Cooper once did a joke where the chap tells his doctor he's broken his arm in several places.
The doctor replies, "well, don't go to those places".

With this in mind, surely the obvious solution to this problem must be "well, don't go above 55".

Thank you, I'll fetch my coat. :xd:
