Reply With QuoteWD 40 is basically only fish oil, have you tried Penetrol or anything similar? Might get in better. Keeping the pressure on and repeated side impact is th only thing that I can think of after the heat you have already applied.

SubscriberI'm having trouble removing a timing surround from a small engine which is on a tapered shaft with a key.
I've tried using a puller as in the picture, but I can't put too much pressure on it as it bends the component.
I've tried soaking the shaft in WD40 for days, and I've just tried heat in conjunction with the puller, but no luck.
I've also tried tapping the end of the puller with a hammer, but the threaded shaft is quite small, so I don't want to damage it by bashing the crap out of it.
Does anyone have any suggestions ????

Is that a thread in the hub you could use that as part of a pusher if so

Lots of pressure on the puller,some heat and wollop the end of the puller thread straight on with a hammer. Pat

Can you fit the whole lot in a chest freezer overnight and then use heat in the morning?

SubscriberDon't hit the end of the threads directly, turn a nut on till its above the end of the shaft and hit it to protect the threads.Originally Posted by PAT303

SupporterIf it will fit to give a little clearance , put the nut back on , high enough to clear the puller shaft as in not contact with the puller shaft so`s to protect the thread .
Do the puller up as much as possible .
Lift the whole lot into the air so`s it clears the bench .
Hold it by the puller and hit the puller shaft with a hammer sharply . Use gravity .
If mine i would do the puller up and tap the screws to judge the tension lift it belt it till it parted then repair the thread if needed .
You may know , the correct puller screws into the large thread inside the flywheel close to the shaft .

Ancient mariner is onto it. You need a puller that uses the internal thread of the fly wheel, tension up tap with hammer all good.

looks like stainless timing surround?
if you use the internal thread (my recommendation as well) use plenty of antiseize on the thread and a bit on the shaft when you reassemble.
maybe one of the generic hydraulic pullers will screw right into that...
best of luck... some of them can be utter mongrels

SubscriberThat's pretty much what I've tried, but I don't want to damage anything by applying excessive wollop
I don't have a puller to suit, but it might be worth trying a chainsaw repairer or similar. Using that big thread would be much better.
Yep, everything on this machine is stainless or ally as it's fully submersed in salt water. It's an Aquascooter as in the pic, made in Italy, Bosch timing etc, all seems to be very well made. It's given us many years of fun and I'd like to give it a freshen up with some new rings, piston etc etc, and that means splitting the casing to remove the bore sleeve, but I can't do that without removing the stubborn timing gear.
