Edit: I've added some tips GTS 300 HPE Engine removal 🤬 (Post 2656059)

FYI

It's different to the pre-HPE ...

Requires removing the floorboard to get to the connectors for the stator etc. See connectors 11 + 12 in pic from the workshop manual*.

I'd watched Robots video for a pre-HPE and he didn't have to. So I started and was going well and then found this. I'm 98% done but have decided to stop for the day and drink beer and cry on this forum.

f**k 🤬🤬🤬


* pic is from the sei giorni workshop manual but is same in the german supertech manual that I have.

I'm surprised that there's not enough slack to pull those out through the hole. Can you relocate those connectors through the hole so that you don't need to remove the floorboards in the future?

iirc the white connector in the photo is attached to a metal plate. So no pulling on it.

You could clip the wires where you can reach them, then add connectors where they are reachable.

If you cut and add connectors, I suggest you use Anderson Pole connectors:

Sometime it's possible, depending where the part you need to get to is and how dextrous you are, to lift up one side of the floor and use a rolled up towel to prop that part of the floor open, so you can reach in and do what needs to be done without damaging the plastics or removing a portion of the skin on your forearms.

On my pre-HPE scooters it used to take me one day of hard work to get to that stage.

Then it took me a second day to install the Malossi V4 kit, and a third day to put it all together again. I wouldn't dream of tackling it with my 2023 model. Rather pay a Vespa mechanic at a reliable workshop. It's got too difficult with the new model, and I have got too old!

But why are you doing this? Something gone wrong like a leaking gasket? You certainly don't need a Polini cylinder for the country riding you do.

Yeah, a full day for removal is about right.

But why? This: Rhetorical: should coolant be coming out of my exhaust manif

I've done it three times. Didn't get any easier. Just had to resign myself to the fact that it takes three days. No point in hurrying.

I found the hard part was getting the rings into the piston and then getting piston and rings into the barrel. Oh, and lifting the engine up to put it on my workbench, and finding the circlip once it had shot off somewhere. Good idea to have some spares handy.

so true. it seems to take about 1/3 the time to yank the motor as it does to get it all back together and back in the bike and running.

anyway, it's not a race. take your time and do it right.

like the shop foreman at a job I had Mr King would say: why is there always time to do it twice but never enough time to do it right the first time?

Perhaps you've got the beer: work ratio all wrong.

Yeah, it's a bugger, but you're at a bit of a low point at the moment. It gets better...I hope.

tips:

* watch robot's videos

* write down the list of zip ties you cut. yes take photos as well but write the list.

* lift the floorboard. loosening the glovebox and partial lift of the floor is enough.

* the black plug was rotated 90° to the photo and didn't have enough slack in the wire to undo it until I separated it from the metal bracket which is held with one easy access bolt.

* undoing the big white plug was a pain. it's a squeeze the tab style but I found it too hard to squeeze. used a small screwdriver. slide the screwdriver where I put the red arrow

* you'll have to unbolt the voltage regulator bracket to get the big white plug out. two bolts that go into the bottom of the frame (iirc hidden under the battery tray).

I'm surprised you left the wheel and the transmission bits on - they weigh a lot, and you need the transmission cover off anyway to turn the crankshaft.

But you got it out.

I had removed the trans cover but temp put it back on.

Needed the wheel to be able to drag it from my front porch to the back porch

Without those bits I find that engine quite 'liftable' - and I've got a dodgy back! I reckon I could carry it for quite a way with no problem. But that's just me.
