diy k11 micra clutch change

lostboy

hello, first off some background, ive been rebuilding 2 stroke motorbike engines for a few years now, could probabaly do one in my sleep at this stage, hoping to start on some 4 strokes shortly.

theres a k11 micra in the family and the clutch is about to go in it, theres still some test on it and its probabaly only worth scrap with a gone clutch but the car is otherwise in very good order bar a driveshaft. a clutch kit can be gotten on ebay for 65 notes and if im honest id like to tackle installing it myself but i havent done an awful lot of work on a car.

ive looked at some clutch changes on youtube and it seems like somthing i would be able to do myself but there is nothing k11 specific ( i hear its very handy to drop the box on these)
few questions though.


are all 1.0 k11 clutches the same?
is there anywhere online or in a service manual that will give micra specific advice/directions
given my level of experience is there any reason why i should not attempt this job myself?

A car is a lot different then a 2 stroke engine to be honest it's not a difficult job but u need to know what ur doing.now I'm all for people learning and trying them selfs but what happens when u have that car stripped at home and something goes wrong when ur doing the clutch and let's just say u ring a bolt on the starter r r u have a leaking seal on the gear box. Even something simple that even the best mechanic can do like cross tread a bolt.

Then ur stuck and u need to pay a mechanic to come fix it. Have u ever lined up a clutch disk before it has to be spot on
These are all the things that u need to ask yourself I can give u any amount of advice u like and I'd be delighted to but unless u no exactly what I'm telling u it's pointless

if im honest a dead seal or wringing a bolt wouldnt really phase me, been there done all that before on my engines it will be a learning process and if somthing like that goes wrong i wont be too stuck since the car is off the road as of today anyhow and theres no hurry to get it done.

Sounds like your good with your mind & hands, shouldn't be an issue. Also once you've got some where to work on it, you'll be under no pressure to do it in a day etc. You'll need to safely support the car and get something under the engine to support it too for when the gear box is removed.

You can make up a clutch alignment tool or even buy one of ebay for €30. If your buying one i'd go for the one with the various size bushings in it, and not the ones that expand out.

Its sounds like the perfect project to learn on. Lots of people here that will help also if you get stuck on anything.

Yes you should be able to manage with out any bother. All the bolts are large and accessible in comparison to your usual fettling. I rebuilt a YZF recently and you'd need six fingers on each hand to fit the gearbox, holding both shafts and forks and selector drum to install in one go(more like twelve).
So the micra box should be easy for you,
Remove airbox, drive shafts, all connectors onto gearbox, gear selector rod, battery and battery tray, starter motor and then all bolts securing the gearbox.

Remove gearbox, and then remove the bolts securing the clutch. Fit new clutch making sure you allign the clutch plate.

Refit everything in reverse.

sounds good, am i right in assuming the only reason the clutch needs centering is for the bellousing to line up on reassembly? if its not centered it all wont go back together?

paddy, i mostly do older vespa engines but ive got a modern 4 stroke here that will be rebuilt soon, i know what you mean though, ive done a couple of 125 engines and they can be a bit of a bitch to go back to gether.

Use a tool to align the clutch disc to the flywheel when the clutch is bolted in place. Eyeballing it isn't good enough because the gearbox input shaft may not slide into place when you try to get it into position. Tighten the pressure plate bolts gradually in a star pattern to avoid distorting the clutch

If your handy with mechanical things, as it seems you are, then there is nothing complicated about a clutch change on a Micra. They are about as straight forward as you can get.

You can get a universal clutch alignment tool from Halfords for very small money and other then that, all you need is a decent tool set.

The problems that a you may encounter with a lack of experience are removing the drive shafts from the box and hubs and removing the bolts from the suspension etc as in some cases these can be very seized.

The other thing is lifting and aligning the box into the correct position can be very awkward for one person on the ground.

Ill have a set of extra hands when needed. i was going to leave the shafts in which i read could be done but one needs doing abyway so ill take them out. watching a youtube video for some old fwd toyota and the hub nut and split pin are all that holds them in. would the k11 be the same?

The Micra is the same but you will likely need to undo the bottom shock bolts as well to give clearance to remove the shafts.

ND do you know are all the clutches the same for the 1.0 k11 or was there different revisions? i see some on ebay are 170mm friction plate and others are 180 etc, we got a k11 clutch last year for somebody else and it wasnt much dearer than online, the guy wanted the reg of the car to make sure he had the right clutch? for the sake of the 15 notes or so i would buy from him again so i have the right clutch to hand when the box is split
