DippedHeadlights Posted November 1, 2023 Report Share Posted November 1, 2023 Am I right in remembering someone made an improved version that is less likely to leak? From a different material? Been looking through my notes and I can't find any info. Link to comment Share on other sites More sharing options...

Josef Posted November 1, 2023 Report Share Posted November 1, 2023 Huh. I was wondering if I’d imagined the CNC version, or if it was out of production… I’ve two distorted and stripped ally ones and need a replacement. So at a tenner over the original style one I know what I’ll be getting! Link to comment Share on other sites More sharing options...
Pete Lewis Posted November 2, 2023 Report Share Posted November 2, 2023 most strip due too long set screws bottoming out .and gorilla hands at work can be repaired by upping to a 8/10mm metric or even a 3/8unf if bent for whatever reason then thats more of a challenge do note there are a selection of screw lengths on sumps and timing covers that need to be observed or stripped/ bottomed out will prevail pete Link to comment Share on other sites More sharing options...
Colin Lindsay Posted November 4, 2023 Report Share Posted November 4, 2023 They certainly distort... I checked this old original against a new steel version and there was a huge gap. No amount of refacing would cure that. The new one was a great improvement, certainly saved a lot of oil. The bolts are only supposed to be lightly tightened, not so as to distort the sump and the sealing blocks. Link to comment Share on other sites More sharing options...
mpbarrett Posted November 5, 2023 Report Share Posted November 5, 2023 I have often wondered why Triumph made it out of ali? Cost? cant think of any engineering reason not to make it out of steel. mike Link to comment Share on other sites More sharing options...
johny Posted November 5, 2023 Report Share Posted November 5, 2023 Aluminium expands quite a bit more than steel with heat so whether Triumph were thinking an ally bridge piece would self seal better than a steel one.... Link to comment Share on other sites More sharing options...
Peter Truman Posted November 5, 2023 Report Share Posted November 5, 2023 Ref the little timber wedges at the ends there difficult to get over here has anyone tried gasket compound ie Hylomar or similar as an alternative and was it successful. I suppose I could try making some using a soft wood that expands when wet Link to comment Share on other sites More sharing options...
JohnD Posted November 6, 2023 Report Share Posted November 6, 2023 Pete, they are just wood, easy to whittle! And no need for a fancy wedged shape, they are just short lengths of wood 'bar'! Slightly wider than the slot and a bit longer, tap them in and the excess width is shaved off. Excess length with a sharp chisel. I put some hylomar in first and on the wood, but I don't think hylomar alone would do it. John 1 Link to comment Share on other sites More sharing options...
