Adam Faal Posted July 20, 2010 Share Posted July 20, 2010 Hello, the NATO hook was on my 90 when I bought it but I have never used it. When I checked it out today I found that it have seized, it won't rotate. I tried to loosen the big Philips screws, to see if I could take it apart to lubricate or clean it up but the screws wouldn't budge. What's your experience, is it worth the effort to get those screws out by some means or will it be knackered inside anyway? The hook looks like this: Cheers, Tomas Quote Link to comment Share on other sites More sharing options...
western Posted July 20, 2010 Share Posted July 20, 2010 leave it closed, use a grease gun on the grease nipple [marked as 1 on your photo] to get grease into the pivot area, get a long bar & slide it in the hook area [2] remove the pivot lock pin [3] & move the lock bar [4] clear, then rotate the hook with the longbar until it frees off. also remove the pins marked as 5 & 6, so you can clean up the pins & parts of the top latch. did this to mine recently & it now works easily. good grease such as a general purpose vehicle/wheel bearing grease will be fine Quote Link to comment Share on other sites More sharing options...
Les Henson Posted July 20, 2010 Share Posted July 20, 2010 Use an impact driver on the screws - that usually undoes them. Les. Quote Link to comment Share on other sites More sharing options...
Adam Faal Posted July 20, 2010 Author Share Posted July 20, 2010 Thanks for the advice, I will try the grease route first, then I might not need to loosen those screws. Cheers, Tomas Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted July 20, 2010 Share Posted July 20, 2010 Big vice, big scaffold bar through the jaw, something will move eventually Quote Link to comment Share on other sites More sharing options...
Adam001 Posted July 21, 2010 Share Posted July 21, 2010 Yeah as above, they sieze up if left for a while, my NATO one was locked solid on all pivots, now rotates smooth as butter big bar did the trick on the rotating part Quote Link to comment Share on other sites More sharing options...
mike4444244 Posted July 22, 2010 Share Posted July 22, 2010 If it's completely seized you can leave it in a bucket of diesel for a few days, then repeat the above Quote Link to comment Share on other sites More sharing options...
forkrentfitter Posted July 22, 2010 Share Posted July 22, 2010 check on the back,many of them were welded so they could not rotate!! Quote Link to comment Share on other sites More sharing options...
Glue Posted July 22, 2010 Share Posted July 22, 2010 When mine seized a few years ago I simply(!) undid to four screws that hold the front plates to the back, then pumped some grease in through the nipple. This forces the hook to separate from the "spike" it rotates around. After that it was just a case of a good soaking with some penetrating oil and a regrease to restore it to full working order.

Quagmire Posted July 22, 2010 Share Posted July 22, 2010 I did this today, as Western said- grease (I kept shooting in new grease until the old carp started to ooze out) then undid the locking mechanism and stuck a 2ft long bit of square tube through. Then I twisted to free it off and re-greased. Job jobbed Quote Link to comment Share on other sites More sharing options...
