CAN you change the big end and mains on a 3 bearing crank with the engine in place?

I’ve got the 5mb and you should be able to do that , one at a time , need to ensure correct half goes in on mains then you can slide it round to the upper end of crank pushing the old one out first
then put lower half in cap , with the big ends rotate crank then push piston up to get enough clearance to install
This is my 200tdi but currently doing the series
only do on a still day to avoid dust getting in

rear main will be a struggle but the rest fairly easy

It will only push out one way as one end has a bit swaged over to stop it moving in housing
The rear main
being wider will need a bit more effort but if the other 2 mains bolts are backed off a bit that will give more clearance
the hardest bit will be getting the T seal back in

Is that with the bell housing attached?

well we made a slide hammer to the bearing cap and hammered away until the steel strap 25 x 1 with a sump bolt deformed and the bolt head punched through. buggrit. i'll leave it. sounds really smooth now but the front crank oil seal is leaking a drip every 10 seconds.....

So... I want to do the big ends on a S3 petrol - assume this'll be easier than doing the whole lot... Did anyone ever answer Ciderman's question about the bell housing? I don't want to take out the gearbox if I don't have to....

Big ends no problem, but as your in there at least check mains

Big ends are easy- mains as well but--- the rear one is difficult.

Excellent, thanks very much - I've been putting it off because I don't have a hoist for the engine. Now I can get into the cool darkness of the PIT!

Sounds like the two hemispheres are running at similar temps - we've got nice cool nights but the days are already up to 30 deg C - it's s'posed to be winter here.
