So, the ongoing saga of my Sons Aygo.....

Have prepped engine for removal. I can’t get the car high enough to remove the engine and gearbox together so I am trying to separate the engine and gearbox and remove just the engine upwards. It should be possible as the Haynes manual tells you how to remove just the gearbox.....

Anyway, everything removed, unbolted etc. But engine refuses to separate from the gearbox. Any top tips - I don’t have a blow torch so I can’t apply heat

Thanks...I’m not looking forward to ‘refitting is the reverse of removal.....’

Cold chisel + lump hammer + mechanical sympathy.

I have never seen a FWD engine/gearbox out of a car - so this may be irrelevant - but I know when i was trying to separate (and reattach) my Pinto/RWD gearbox having a load leveller on the hoist made it SO much easier. If you've already got the engine lifted on a hoist and are trying to separate it, it could be the angle at which the engine is trying to lift that's stopping it separating?

First off....if you were even contemplating applying heat to help separating the engine and box, please put down your tools and walk away. Were you going to get the entire engine and gearbox glowing hot?!

In my experience, the bellhousing wil be located to the engine block with two or three hollow dowels which are a snug fit. Once these are moved a couple of mm, the box should come away easily. Find where these are and use a shallow wide chisel and see if you can get things moving. Just a mm at a time.

Also in my experience, if it's that hard to shift, there's still a bolt in somewhere! Either tucked up behind the starter motor or one that is orientated differently from the usual suspects.

Good luck.

Thanks - a small amount of sympathy applied....it’s now clear of the dowels but won’t separate more than a cm or so...
Guess I need to play with the angles!

+1 for last comment owelly

My thoughts as well

So you're attempting to remove the engine and leave the gearbox in a fwd car? Personally never seen it done like this. You either take the gearbox out or take the lot out. Just cos the Haynes manual says you can take the gearbox out on its own, which you usually can on fwd, it'd be very wrong to assume the engine can come out on its own.

if there are no hidden bolts,push on the release lever, prob the spigot bearing stuck on the input shaft, dont try big levers or heat as you will enter a world of pain.

I recall this was tricky when I split the Yaris box of to do the clutch and it was just tight and needed to be pulled of straight, not wangled off at an angle, which in itself it tricky with not much room. Persevere

Or the clutch plate stuck on the gearbox splines.

It looks possible - there is space to do it and if it works then I don’t have to disturb/remove driveshafts.......

Trying again later today..

Shouldn’t be an issue as long as you have enough room to take it out ‘straight’. The dowels usually arnt long enough to keep everything inline until you read the end of the splined shaft, I would get some long bolts cut he heads off and put them in where you took out fastening bolts, that will help slide everything out inline and also same when you put it back in. Some times a little tappy tap with a rubbber mattet just releases anything that stuck/sized.

Yep - some long rods to keep it all straight did the trick. It’s now fully separated and balanced on the trolley jack.

Just waiting for the loan of the neighbours engine crane to get it out!!!

Thanks all

Can you jack the car up and slide it out underneath??? ;-)

It’s out! Was easy enough once it was all lined up.

It could have come out downwards but it’s a really tall engine and I would have to get the car up high, plus I was trying not to disturb the driveshafts!
