Ultramatic Rebuild for a '51

Posted by Larry51 On 2015/10/6 1:15:14

A couple of minor oil leaks from my Ultramatic have made me decide to do a partial re-build of a spare unit that I have, and swap it into my '51. Am hoping the Ultramatic experts here can provide some answers please.

Firstly, the workshop manuals don't specify just how much lining material should be on a 'useable' Low or Reverse Band. I only have a couple of used bands, and the layer of friction material on these is even but very thin - it's only approximately 1mm thick. So I can't be sure if they are suitable to re-use or not.

What would the thickness be on a new or 'OK' band?

Likewise, approximately how thick should material on the direct drive driven clutch plate linings be?

Next question relates to special tools. Manual reckons I need quite a few of them. What's the general feeling about needing special tools for a partial rebuild (- replace clutch plates, bands, seals and gaskets)? I'm not intending to fully disassemble the Ultramatic. (The Kent-Moore Tools List doesn't help me at all).

Any suggestions/ opinions about tools would be appreciated. Thanks!
