Could a flywheel be loctited on the engine shaft

steamyman · Could a flywheel be loctited on the engine shaft

I mislead the grub screw and key.

It's a wheel from Graham Industries.

I would try contact them first to see if you could get a spare.

Loctite can be used, but just isn't the same

I wouldn`t loctite in that situation.... Ever.

You will find the original, or obtain a replacement, soon.
It will be a common thread size, without buying an expensive "spare part".

A lockted flywheel won`t come off again, soon......

I had a mamod mazac flywheel that the grub screw thread was stripped, so you couldn't tighten the screw enough to get it to grip the shaft.

I used some cheap superglue and it worked a treat, so as a quick and dirty fix it's great, future disassembly may be more of a problem however, but I'm not convinced it's that strong to be honest.

I was under the impression that loctite and superglue come adrift when heated as we use it on our woodturning tools with replaceable tips .just superglue on and heat to remove

steamyman

hmmmmmm. now i'm confused....might goto my local model engineering shop tomorrow- they may've a spare.

Yes I would email the company you bought the engine off and ask them what size grub screw they used and then buy a new one.
If its a meteric thread you probably could get one from a good model shop as metric grub screws are used in a lot of RC cars.

Superglue is quite good at holding items together, for dissasembly you just need a little heat on one part, the heat makes the part expand and breaks the grab of the cyano. Make sure you do this in a well ventialeted room though as any resulting fumes will not be good for your health!

You can use this for attaching small items using a faceplate - or technically a super glue chuck when doing some lathework too.

In the case of missing grub scres I suggest you find a replacement, or even better than that - get a supply of various grub screws in different lengths and threads for a future supply! It's annoying to lose one on the floor and then have to wait to get a spare - much nicer to have a tray with the odd ones floating around in it.

There are different grades of Locktite too, one grade will be like welding it on and you wold never be able to remove it without damage. other grades only keep it from slipping somewhat but not under stress.
I would get the proper grade of locktite and put it on the threads of the new grub screw once you get it. If unsure if you have the proper grade of Locktite, do not use it at all.
