[QUOTE="cunning plan, post: 606852, member: 4090"] I purchased a brand new 70amp alternator conversion kit which came with the oil filler pedistal, backing plates and strap. I then bought a new fan hub fixing kit to use with my old shims and a used 'wide' 35/36mm fan I had on the shelf. I put it all together expecting to have that part of the engine build done in 10 minutes and 2 hours later I was still trying to figure out what was wrong with the fan as it had a very noticeable wobble, so there was lots of taking it apart and rebuilding using various combinations of old and new parts in an attempt to identify the issue. I finally decided that the old fan must be the problem and it must be warped somehow, so I purchased a new 35/6mm fan (one of the £28 ones from VWH). So that arrived, but there is still an issue with the fan wobbling!! :roll: I have tried swapping combitions around using the old 'thin' fan, fan hub parts, shims etc, but this video shows the best I can make the fan: [youtube]wXypgyhki5c[/youtube] This does not seem acceptable to me and the unbalance would create extra wear on the alternator. What do you all think? I am starting to think that the alternator spindle is misaligned. [/QUOTE]
