Bush assembly

Abstract

A bush assembly comprising a component having a bore, a bush fitted in the bore and having a flange that extends radially outwardly over a surface of the component surrounding the bore, and a seal assembly for sealing the interface between the flange and the surface of the component, wherein the seal assembly includes a seal member and a layer of sealant between the seal member and the interface between the flange and the surface of the component. Also a method for sealing a bush, a kit of parts for forming a bush assembly, and a clamping tool for forming a bush assembly.

         15 . A clamping tool for applying a clamping force for sealing a bush installed in a bore in a component, the tool comprising a first part, a second part and a clamping mechanism; wherein the first part comprises a recess which is adapted to engage a seal; the second part is adapted to engage a surface of the component which opposes and faces away from a surface of the component on which the seal is provided; the clamping mechanism is operable to move the first part relative to the second part, thereby applying a clamping force to the seal; and wherein the clamping tool includes centring means for centring the clamping tool relative to the bush. 
     
     
         16 . A clamping tool according to  claim 15 , wherein the tool has a longitudinal axis. 
     
     
         17 . A clamping tool according to  claim 16 , wherein the clamping mechanism is operable to move the first part relative to the second part along the longitudinal axis of the tool. 
     
     
         18 . A clamping tool according to  claim 16 , wherein the centring means is 
     
     
         19 . A clamping tool according to  claim 15 , wherein the first part has a working surface which is adapted to engage the surface of the component. 
     
     
         20 . A clamping tool according to  claim 15 , wherein the clamping mechanism includes a stud having a threaded end which is threadedly engaged with the first part and with the second part. 
     
     
         21 . A clamping tool according to  claim 15 , wherein the first part has a working surface adapted to engage the seal. 
     
     
         22 . A clamping tool according to  claim 21 , wherein the centring means comprises a cylindrical surface projecting from the working surface of the first part. 
     
     
         23 . A clamping tool according to  claim 21 , wherein the recess is formed in the working surface of the first part. 
     
     
         24 . A clamping tool according to  claim 21 , further comprising an O-ring seal in a groove formed in the working surface of the first part. 
     
     
         25 . A clamping tool according to  claim 23 , further comprising an O-ring seal in a groove formed in the working surface of the first part, wherein the groove has a larger diameter than a diameter of the recess. 
     
     
         26 . A clamping tool according to  claim 15 , wherein the second part has a working surface adapted to engage the surface of the component which opposes and faces away from a surface of the component on which the seal is provided. 
     
     
         27 . A clamping tool according to  claim 24 , wherein the centring means comprises a cylindrical surface projecting from the working surface of the second part.
