Engine - 80-84 1275 metro

 

rebuilt nearly 1 year ago with not that many miles

 

so after its first motorway trip and back it developed a horrible sqeek from the left hand side of the engine (looking at it)

after stopping in at the new local mini garage (awesome set of fellas by the way ) the diagnosed it was more than likely the ''thrust''

bearing and that I can drive it but if it goes I won’t be able to change gear ......

 

now guess what I cant change gear, also there some disturbing clanking sounds at low rpm that wont there until I couldn’t change gear

 

So my really question is

 

Now what? What exactly needs to be purchased

how much would your average garage charge to do this (the local mini garage told me the ins and outs of what’s involved)

 

we would tackle this ourselves but my granddad bless him is getting to the other side of 85 and we still have a series 2 landy to finish and we don’t have time for this mini's tantrums SPECIALY MID SUMMER! haha

Did you install the thrusts the correct way round?

[Ethel]

I suspect they meant clutch release bearing. Is there any difference in the feel of the clutch pedal? It's fiddly, but not a difficult job to remove the clutch cover and find out.

[Classic1275cc]

The pedal it's self seems no differant

As for the correct way round I dident put it on my self so can not be certain but ither way looks like it's comeing off

Any idea if the garage price to get this done ? I wanted to take it to MITP but looks like I'll have to take the spi but that's a bit more mundane

You dont say what year the mini is ... but if you can easily get to the clutch housing (so no servo to remove) then I'd say a maximum of 2 hours time to fit plus parts. Thats assuming it's just the release bearing.

Do not build your shopping list yet.

 

You are correct that if it is the thrusts, the engine has to come out.  This is not something that a generic local garage is necessarily capable of doing. The engine has to be taken out, separated from the gearbox, and at least placed on its side to see what is going on (if not put on a stand for disassembly).  It would be premature to advise you on what is required to fix the problem until you identify what went wrong.  For now, simply plan to remove the engine and do an examination to locate the failur.

There's Servos in the way

It sounds like the clutch release bearing has gone and it is a simple job to change it.

You just need to remove the clutch end cover (the 'wok'), remove the plunger, change he bearing and re-fit it.

The only difficulty is getting some of the 5/16" UNC bolts out of the cover. You need a good set of spanners to be sure of having ones that will fit.

Undo the engine mounting under the clutch end of the engine, Undo the engine top steady, remove the radiator to thermostat housing plate, Jack the engine up about as far as it will safely go at the clutch end, making sure the fan does not hit the rad. If you have a later Mini without the inner wing box at the radiator end you may not need to remove the thermostat housing to radiator plate.

Once the cover is off, remove the clutch arm and the clutch overthrow stop nuts and push the plunger through and out. Replace the bearing and re-fit.

The overthrow nut and its locknut must be re-set after re-assembly is complete.
