engine removal

[el_oso]

im having a really tough time in getting the engine out of my diversion. anyone done this?

it seems like the the two rear mounting bolts are not actually bolts but instead are nuts. one of which is rounded. just wondering if i can take a hacksaw to it to remove the nut? ideas anyone?

Probably it's two nuts on each end of a long shaft which runs from one side to the other, if you've got one off, try knocking it through.

yeah i thought the same thing as well. trouble is that the left and right sides don't seem to line up. going to get my mums car out the garage and have a proper look in a minute.

You could try tapping the nut round with a punch.

Hi

Looking at the manuals and parts list it looks like there is just a single long rear mounting bolt for the Divvy engine, with a nut on one end.

If it has 2 nuts on it then it suggests someone has bodged it in the past with a length of threaded rod and a couple of nuts (cheap from B&Q and the like).

How rounded is the nut? If only just rounded then it will probably come out with a half decent quality hex socket (rather than a bi-hex one).

All the best

looking at the bike in some proper light this morning it looks like it is just one single long rod. i've undone the nut at the other end and tried bashing it through but it just doesn't seem to want to budge. i've tried lifting the engine to different heights to get the pressure off the rod and even tried lying it on the ground and tapping it through but it hasn't budged a millimetre. i've also had a pipe wrench on it this morning and it still won't move. i thought that if it was one big rod then it should spin fairly freely at the other end but nothing so far.

Hi

I would suspect what has happened is that the bolt has seized to the alloy of the engine.

I would be tempted to get some decent penetrating oil (not just WD40) and try and get some on the bolt where it goes into the engine cases. Repeat this regularly for a few days . Then try a bit of heat (carefully) on the engine mounts and try putting a socket on the bolt and turning it again.

But do at least use a good quality 6 point socket. A bi hex one will just slip on that and chew it up even more.

All the best

this is also what i expect has happened. there is no chance of using a socket. The socket which is was using was a high quality workshop set which belonged to my dad. been using a long pipe wrench for the last half hour after letting some wd-40 soak in while laying it on it side. also applied some heat and still no go. been applying so much force that the bike is actually lifting up off the floor
really am stuck at this point

Hi

Is the socket you have been using a proper 6 point one? Most sets are 12 point bi hex. Would expect a pipe wrench to just slip easily and destroy the bolt head.

Also WD40 isn't a good penetrating oil. It sort of vaguely works for that better there are oils specifically sold for the job that will be far better.

All the best

It was a very well fitting 6 sided one that rounded it, it's by far the most rounded bolt I have ever seen.

Looking at the rounding on that head, I think we are onto plan B!!

You might want to try a blow torch along the length of the bolt/engine casing. The heat should help you out.

My only other suggestion is to weld a bar (or old socket) onto what remains of that bolt head. If you can get some rotation on the bolt, then it will then probably 'bash' out.

As I said, you could also try getting something with a sharp point and using it to bash it round. Maybe hacksaw a slot into it first to get some grip.

[c_dug]

Not sure we will be able to get enough force on it by hitting it around, it seems pretty stuck, or at least it was last time I saw it.

If it's a rod going all the way through surely it can be bashed through with a persuasion device? (Hammer)

Hi

Wouldn't bank on it, and turning normally will crack it off far sooner (as you can apply a hell of a lot of torque).

All the best

Hang on, you say it's rounded, but then you say you can use a pipe wrench and it still won't turn?

Is the bolt head actually rounded off?

[Kickstart]

[el_oso]

using the pipe wrench managed to move the bolt about half a turn but it is still refusing to come out. given up for today.

going to try again tomorrow

buy a set of easyouts https://buy1.snapon.com/catalog/tools.asp?tool=all&Group_ID=16597&store=snapon-store

i got a cheaper set always handy to have

[TUG]

Just grind it down? A paint stripper to heat it up will also be a great idea and make your life easier and lots of WD-40 or silkopen.

Btw if your removing it for an engine strip down its a good idea to get it to the bare minimum before removing.
