Power harrow.

[Sunshineyday]

I have a power harrow. Approx 10 year old. My problem is,the main rotor shaft,coming out the gearbox, which holds the tines on,backs off and eventually unscrews itself. It has come off totally previously and I lost it! Sad face...Amazingly, with the help of a friendly metal detector, I located the blade carrier,shaft and another essential part.(I noticed a slight ridge in the worked area/strip.) Please can anyone recommend a real strong locktite product to hold the shaft on. Tried threadless,bearing lock/seal,and maybe,if I remember correctly locktite 262 or similar. Last time( 3 or 4 years) i used 262,cleaned up everything scrupulously with petrol etc.
What products can people recommend.
Thanks.

Thought you said it was the carrier
How often do you take the carrier off?

Just a spot,can be ground of if need be

What sort of lock nut is on it?

What sort of lock nut is on it?

No lock nut. A fine threaded shaft which screws up into the carrier and into the trough. It holds a 4inch,maybe,round saucer which hold quicfit blades on,then a special 1inch lynch pin holding the whole assembly and blades in situ..
Job to get a spot of weld on without fouling this 4inch saucer thing which recess in under to hold blades.. need super-duper strong thread lock product..
