This is 1/40", within Ariel's stipulated range of 1/64" - 1/32".</p><p>All good news; however, since tightening the inner case nuts for what I thought was the last time, I've realised that the camshaft is too tight. It turns, but that 2 thou end float has clearly been taken up by gasket compression - I may relieve the bush a little or I may fit shims to 0.2 mm (8 thou) rather than the 0.3 mm currently fitted (12 thou) which should give me what I need.</p><p>As it turned out, smoothing the surface of the camshaft bush was all that was required to return to normal operation, so I tightened up the end cover. The last step was to fit the two Welch plugs, which have to be done before the sprocket goes on for the last time. It would have paid to ensure the bores for these were clean before the bushes went in, as enthusiastic staking at the factory had left a lot of material in the layshaft bush bore which had to be scraped out with a twist drill ground flat, like an end mill.</p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjMOkhT5dS0U9LgLicxFo9BdL9KaaC9jUFXFGJ84xdzJB9-HyTDyVXwjmThcbA4MyrteC3c2E78fMvYxv2olnXod1oY9Oo21ZuOLBBiAmyYOjnSk3eg7d4l1IXA8-3qOmbuBOSwviImypRLa945u_7KXsfsRibQuQIALEqvozJfxFBjj0k5GRYvwLOnDYPU/s4096/IMG_20240215_155009~2.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3072" data-original-width="4096" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjMOkhT5dS0U9LgLicxFo9BdL9KaaC9jUFXFGJ84xdzJB9-HyTDyVXwjmThcbA4MyrteC3c2E78fMvYxv2olnXod1oY9Oo21ZuOLBBiAmyYOjnSk3eg7d4l1IXA8-3qOmbuBOSwviImypRLa945u_7KXsfsRibQuQIALEqvozJfxFBjj0k5GRYvwLOnDYPU/w640-h480/IMG_20240215_155009~2.jpg" width="640" /></a></div><div><br /></div><div>Next job is to close up the other end of the gearbox, but I can't do that without the clutch in place as I can't hold the mainshaft to do the nut up on my own.</div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiVbw8TSVdnNvnAcJ8xasysUNeO0Z_IvmD5hSk69Ke6T5nnEtCpNwd8IPsFpESxiSsPkJJvqW9Op6Rjh9RMhyF_b45oOmzS4CTLQPjpLgOel_BAAm1voK59JFpOsB1-j8J7eg-7REPTgkf8h9_dM6Rju6Yddk6N-rSeIFdWFvEms0l7LVirvJFQVna6bSWC/s4096/IMG_20240221_165516.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3072" data-original-width="4096" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiVbw8TSVdnNvnAcJ8xasysUNeO0Z_IvmD5hSk69Ke6T5nnEtCpNwd8IPsFpESxiSsPkJJvqW9Op6Rjh9RMhyF_b45oOmzS4CTLQPjpLgOel_BAAm1voK59JFpOsB1-j8J7eg-7REPTgkf8h9_dM6Rju6Yddk6N-rSeIFdWFvEms0l7LVirvJFQVna6bSWC/w640-h480/IMG_20240221_165516.jpg" width="640" /></a></div><br /><p>More next time.</p>CharlieCenghttp://www.blogger.com/profile/08734806152020304192noreply@blogger.com0tag:blogger.com,1999:blog-8162393339444825234.post-7102951394050449132024-02-02T19:01:00.001+00:002024-02-02T19:01:04.175+00:00SQ4 Gearbox Investigation <p>Starting the Square Four up mid winter is something I do at least once a week just to make sure it's all working, which it usually is - except when it isn't.</p><p>This week I was met with an unexpected noise, like gear-dogs clashing - it sounds like it does when you put it into first gear.

I was forced to face up to it because I needed to get the Square Four on the lift in order to look at the gearbox before the riding season begins, and I didn't want to resort to holding the stand up with an aerolastic.</p><p>The way I did this was to take a piece of 2" rolled angle and drill a 6 mm hole at one end; I put a long M6 screw in the hole, and the small eye of the stand spring over the screw. Then I took a bit of 1/2" round bar and used it to stretch the spring by levering it against the end of the vice; I put a 5/16" washer in each of the gaps between the wire coils and when the spring was relaxed it was long enough to push into place by hand. All I had to do then was move the stand to stretch the spring again and all the washers fell out. </p><p>Repeat for the second spring and we are done.</p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhrPEY_c6QT7058lZyCdqNm58fYr45c9TajY36OLgC_W0IgtAp0gN58iokPQtWLkuXktQeG0pFD928Vt1PdAlKEdMHAt5JlvwoN83-pe8GXRO0gCAX7fvzhkuhk41pCmDY8e28TjPupapyYxIen7jkhwXy992TBBRKhhQERz7qFjqRouiF1WN5JAqRfQxtL/s3648/IMG_20240111_171229.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="2736" data-original-width="3648" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhrPEY_c6QT7058lZyCdqNm58fYr45c9TajY36OLgC_W0IgtAp0gN58iokPQtWLkuXktQeG0pFD928Vt1PdAlKEdMHAt5JlvwoN83-pe8GXRO0gCAX7fvzhkuhk41pCmDY8e28TjPupapyYxIen7jkhwXy992TBBRKhhQERz7qFjqRouiF1WN5JAqRfQxtL/w640-h480/IMG_20240111_171229.jpg" width="640" /></a></div><div><br /></div><div>First time outside on it's wheels:</div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgS9IyVJAu90sy3C2YqHI3an5ESzqkNsPLpHjwg-g9Z-R-A5lCmiVZRADoZQ18TVad8K7FcAwPS_JwyN35byN3Y0g2gSaa2fVG_V0PGvBZqcYMLJguFuOpLGzP6AofGN4Iu1akuPz0CcmrreF_5MJTU-AxVAlQDfys_IEGfMFCrf8OZ8UUsF15Xed5EpeES/s2412/IMG_20240111_172949.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="1839" data-original-width="2412" height="488" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgS9IyVJAu90sy3C2YqHI3an5ESzqkNsPLpHjwg-g9Z-R-A5lCmiVZRADoZQ18TVad8K7FcAwPS_JwyN35byN3Y0g2gSaa2fVG_V0PGvBZqcYMLJguFuOpLGzP6AofGN4Iu1akuPz0CcmrreF_5MJTU-AxVAlQDfys_IEGfMFCrf8OZ8UUsF15Xed5EpeES/w640-h488/IMG_20240111_172949.jpg" width="640" /></a></div><p>Even my wife says it looks lovely.</p>CharlieCenghttp://www.blogger.com/profile/08734806152020304192noreply@blogger.com0tag:blogger.com,1999:blog-8162393339444825234.post-91986151022641235482024-01-11T08:02:00.011+00:002024-01-22T09:25:50.925+00:00FH - Jeff Hunter Engineering <p> I've written about the value of the specialist suppliers before, in various media.

Roger recommended grinding some material from the cases.<br /><br />What I've done today is make a 1 mm chamfer on the offending edges of the two timing side nuts, so now I know what clearance I need to provide.

I've measured the journals, but I wanted to get some evidence of the clearance that I had ended up with after fitting new -0.030" shells. There isn't much detail on what the acceptable clearance is before you must regrind, other than the data describing the sizes you regrind to and the recommendation that there should be minimal clearance after regrinding.</p><p>Waller indicates 0.003"- 0.004" for the big end shells used on 1948-1955 Square Fours (Fifth edition page 37); Phil Irving quotes 0.001-0.0015" clearance per inch of diameter (Tuning for Speed 3rd Edition), which equates to 0.00165 - 0.0025" for my 1.65" big end. Mr. Irving, otherwise known as 'Slide Rule' using those delightful pseudonyms beloved of motoring writers in the '40's, also notes that the clearance can be much larger as long as oil pressure is maintained.</p><p>So, let's introduce Plastiguage. This is a paste, extruded into rods a bit like Plasticene. You trap a bit in the bearing and squash it, so that the known Plastiguage rod diameter is squashed to take up the clearance of the bearing - you then use the card provided to determine the clearance from the width of the squashed Plastiguage. Plastiguage comes in different sizes to measure different clearance ranges.</p><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgAR8rJD4lh4DTt2GG41NCa350zIK2Qtt1bX7I78Aa2NIRchPnxRTVvNtEVWsEPdGfTmimei2e0r0dWygF8r3GUAwJ_Ejt7O5qAJP9bTKgCdf851m3DaivJ_hBkeH3qJz71VDzz7k-FW7WBi_lOlaX1AgPr-US2lE2MJ2sF00A8aetJh8HaRXEEqnNLrm-I/s3648/IMG_20231117_115055.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="2736" data-original-width="3648" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgAR8rJD4lh4DTt2GG41NCa350zIK2Qtt1bX7I78Aa2NIRchPnxRTVvNtEVWsEPdGfTmimei2e0r0dWygF8r3GUAwJ_Ejt7O5qAJP9bTKgCdf851m3DaivJ_hBkeH3qJz71VDzz7k-FW7WBi_lOlaX1AgPr-US2lE2MJ2sF00A8aetJh8HaRXEEqnNLrm-I/w640-h480/IMG_20231117_115055.jpg" width="640" /></a></div><div><br /></div><div>So, you cut a length to suite the bearing like this, and then you make up the bearing.

There is a question over which one is wrong, exacerbated by the knowledge that the strainers fitted to Huntmasters are not the same as those fitted to BSA A10s.<div><br /></div><div>Now, we all know that 'the Huntmaster uses a BSA A10 engine', but actually surprisingly few parts are common. You would think, given that the crank and rods are the same and the crankcase is identical <i>in some areas</i> (not those relating to the timing chest, which is a different shape) that a simple thing like a sump strainer would be common too - in fact, wouldn't the canny design engineer use the bit that was already available in BSA stores? Well, no. And this my friends is perhaps indicative of why our laudable, innovative motorcycle industry went to the wall.</div><div><br /></div><div>After contacting several experts, it transpires that the sump strainer is indeed different. Given that the strainer was manufactured by SRM (famous for BSA A10 parts) I thought perhaps I had been supplied the wrong one; apparently not. Draganfly Motorcycles, who I bought it from, actually modify the SRM A10 part into a part suitable for the Huntmaster by moving the hole.</div><div><br /></div><div>We Ariel owners would be lost without them.</div><div><br /></div><div><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhhQIB4YV1KsZ7P7ZuIW84FRZK0AZEULYK5aKwyDYXEwX35hjcF8LpYduiFiTKUKwuRkJHUnbyWVvSm8sljFDJV4VEwawL-KYEOvlRdNeKozM_KvZsqdIugYYVRzm0_IO_m48ZHSc-2sls3hKiU1U7XiE5GgiJ7VebHawvKjz6hN6WpA2UVp2JdKvdN1JTd/s3648/IMG_20231109_204139.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="2736" data-original-width="3648" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhhQIB4YV1KsZ7P7ZuIW84FRZK0AZEULYK5aKwyDYXEwX35hjcF8LpYduiFiTKUKwuRkJHUnbyWVvSm8sljFDJV4VEwawL-KYEOvlRdNeKozM_KvZsqdIugYYVRzm0_IO_m48ZHSc-2sls3hKiU1U7XiE5GgiJ7VebHawvKjz6hN6WpA2UVp2JdKvdN1JTd/w640-h480/IMG_20231109_204139.jpg" width="640" /></a></div><div><br /></div><div>It turned out that the pickup pipe was bent - easily fixed when you know what you are aiming at.</div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh-jJU0bR5zt-MVPw5pVwbUabQpbu8yB0oHvB1uzKe3-iipN8_nuUCb4RDtlm6oOyXYUXrJjk1KY76jbGmQq1N5xQiYmuHvrlIVoSuOxfK2jlDQq61hyphenhyphenJXbXvM1kq7lHbRWHAJprAvYa3XHeBejJ0ggG7_PBaxt2og8SR62mN5X_f95sTkl37mhv7gUZH2I/s3648/IMG_20231111_175653.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="3648" data-original-width="2736" height="640" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh-jJU0bR5zt-MVPw5pVwbUabQpbu8yB0oHvB1uzKe3-iipN8_nuUCb4RDtlm6oOyXYUXrJjk1KY76jbGmQq1N5xQiYmuHvrlIVoSuOxfK2jlDQq61hyphenhyphenJXbXvM1kq7lHbRWHAJprAvYa3XHeBejJ0ggG7_PBaxt2og8SR62mN5X_f95sTkl37mhv7gUZH2I/w480-h640/IMG_20231111_175653.jpg" width="480" /></a></div><div><br /></div><div>With everything now fitting together, I decided to use Permatex again to seal the strainer to the sump plate, on the basis that the original pressed metal sump plate would have been sealed to the gauze strainer somehow as they were supplied under one part number and there is only one gasket listed in the parts book:</div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhilOjmJnP6EIKKKpB0dwDYogdKJR9flDGzg9_ejCGr2ZlPIvehBs0Sp6MRaNPimzdA4kAHoTCbq2bn2D-3Lcv4MhkCKn-tkYAB070l_luCmMKEVPNhbeCim1k0D-igaZtptIHn7S-CHGmEXm0NVWGQja9ZgQraifbOvgssekZye6hC8xQInnGG8wyovINO/s3648/IMG_20231111_181746.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="2736" data-original-width="3648" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhilOjmJnP6EIKKKpB0dwDYogdKJR9flDGzg9_ejCGr2ZlPIvehBs0Sp6MRaNPimzdA4kAHoTCbq2bn2D-3Lcv4MhkCKn-tkYAB070l_luCmMKEVPNhbeCim1k0D-igaZtptIHn7S-CHGmEXm0NVWGQja9ZgQraifbOvgssekZye6hC8xQInnGG8wyovINO/w640-h480/IMG_20231111_181746.jpg" width="640" /></a></div><div><br /></div><div>I greased the gasket on both sides as this is a service item and I would expect to remove it periodically.</div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjJfvAX9KHRKu5KAI1FBGRIG-GP6zbmFT3ERT2SW7mXhuB8EvajZP45M4i-FmDlUYi1wp6-YYxewTZP9t1CsWlhIb6vme3wqK30DSi9_lge8LRNfa7dKtjqk-U9wAxjw1rBo_a_vC9l4XW3rYqnoTU2KpvtJX1bR3_nDataAggX2tctkoyxUYS5TMnnnyeq/s3648/IMG_20231111_181954.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="2736" data-original-width="3648" height="480" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjJfvAX9KHRKu5KAI1FBGRIG-GP6zbmFT3ERT2SW7mXhuB8EvajZP45M4i-FmDlUYi1wp6-YYxewTZP9t1CsWlhIb6vme3wqK30DSi9_lge8LRNfa7dKtjqk-U9wAxjw1rBo_a_vC9l4XW3rYqnoTU2KpvtJX1bR3_nDataAggX2tctkoyxUYS5TMnnnyeq/w640-h480/IMG_20231111_181954.jpg" width="640" /></a></div><div><br /></div><div>All that remains then is to fit the sump plate.
