Hi everyone

I have a question about the clutch arm at the rear of the gearbox.
How do I remove it?

Cheers

In a word Gently.  There are roller bearing races in there so remove the circlips  then support one of the tags on the gearbox so it doesn't bust off and use a pin punch to drive the shaft through. Take lots of care and use lots of WD40.

in most cases you can help yourself ....by taking the silencer off first ....it will allow good- better access  you can get a pin punch in pretty much from the rhs  footrest plate direction , but the pin may extend out and hit the exhaust with the muffler still on before it comes clear ...just what I noticed
hope it helps

Remove the circlip on the right end of the pivot rod.  Be careful as it is one of those parts that likes to fly off and get sucked into the black hole, common to most garages, that takes vehicle parts to another dimension via a hyperspatial confluence, never to be seen again. (This is similar to the physical phenomenon that removes individual socks from your clothes dryer.)

Then use a hammer and nail-set to pound the pivot rod out to the left.

Thanks for the replies.
The gearbox is on the workbench. I tried gently heating the clutch arm but I'm also concerned that I will break the tabs.
How do I avoid breaking the tabs?
Thanks

Hi everyone

I decided to give it another go. I was at an auto parts store purchasing a sun shade for the car when I decided to also purchase a nail punch set.
I was in the shed and decided to give it another go.
I placed the gearbox upside down with the clutch arm closest to me and used the largest siE nail punch and copious amount of wd40 to try and remove the pivot pin.
I was mindful of breaking the tabs but I also noticed the tabs aren't of any great length and decided to give the pin a few side taps . I noticed the gearbox moved with each tap and for me, it made me think that the tabs were not taking the full force of the taps.
I then gave the pin a few gentle taps with the nail punch and noticed some movement in the pin. I proceeded to tap it towards the left.
Until I realized the gearbox did not allow the pin to be completely removed.
I then tapped it from the left and it eventually came out. How do I remove the clutch arm at the rear of the gearbox? 723598  How do I remove the clutch arm at the rear of the gearbox? 723598 
I have a few questions.
The pivot pin is a tight fit through the tabs. Is this correct?
The bearings are stuck in the clutch arm. Should I remove them or leave them there?
When I looked inside the hole where the pivot pin passes thru the clutch arm it isn't hollow. I can't see how installing a grease nipple would allow grease to reach the pivot pin and bearings. Am I missing something?
Anyone, that's it for today and thanks to those of you who replied.
Oh I forgot, what type of grease do I apply to the bearings?
Cheers
