Which Number Locktite?

[Oscarpop]

Need to put a couple of drops on the thread of the propshaft to hold the prop on.

I usually use blue locktite and as such just ask the chandler for blue.


Amazon sell 242 and 243.

Which one do I need.?

Look at the data sheets on the Loctite web site.

Enter the product number and search.

243 is supposed to be more tolerant of oil contamination, so might be better for your application. Otherwise similar.

We use and recomend Araldite 2011/precision for under water fixings. It has a low melting point so you can heat the shaft/nut for removal. B&Q have it in small tubes if you can't find the locktite you want.

Is there some reason why you cannot put a split pin through shaft and nut? I like Loctite and often use it but I would prefer somethimg more positive for a prop connection.

if i can put a split pin through then I will.

Changing the prop for a feathering one and there may not be enough of the thread exposed after placing the nut to get a split pin on.

You thinking of just putting the pin through the shaft ???

Pin the nut to the shaft. Either by using a castellated nut or by drilling though nut and shaft ... ?

Volvo Penta say to use Loctite 243 on anodes and propellers.

I may well be out of date on Loctite, but for hanging cameras on Harriers we had Loctite 221 for 'undoable in future' and 290 for 'unlikely to ever undo again ! '.

For something like a propellor though I'd want something positive locking like a castellated nut and split pin, as mentioned.

My uncle who ran an engineering workshop used to tell different grades of Loctite by taste; I did mention he's my late uncle didn't I ?
