Does anyone have any knowledge of repairing (new bearing) or replacing the belt tensioner pulley on a MkIA or similar. The tensioner is an assembly and there seems to be no way to replace the bearing only because it is secured in the tensioner. Any ideas would be of interest.
As no one has responded ninja I mignt as well give you my tuppence worth. Although I don't have MK1A P5 I have fettled a few aircon tensioning belt pulleys over the years. If you can remove the pulley. If the pulley bearing has synthetic plastic seals either side and you can access the seals, you can prise them off. Once the seal(s) is off, clean the bearing with a suitable solvent to remove the dried grease, dry it (hair drier) and then repack the bearing with wheel bearing grease. Refit the side seals and it'll be fine for it's task.
Probably not applicable in your case because I assume that the bearing is of a reasonable diameter and easily repacked with grease. But if it is difficult to get the grease in, a technique that I used some 30 odd years ago to re-grease a small ball bearing worked very well. I prised off the plastic seal on one side only and rinsed out the old grease with petrol. Then I made a strong but fluid solution of bearing grease in petrol, laid the bearing open side up, and poured the solution into it until it was full. Then I left it for several days for the petrol to evaporate. I kept repeating the process until it was full of undiluted grease, and pressed the seal back into place.
PS. It's also better to post questions like this in the specific section of the forum that deals with it. It is more likely to be noticed. This section is used more for general Rover chit chat.
