This is important when talking torque as you do not want to be putting pre-load onto the rotating components of the bearing. I owned a GMH sedan with the same bearings as the Healey BUT GMH do not use this BMC spacer. The purpose of the spacer is to provide bearing clearance but prevent the inner cups, and washers, from rotating. If the bearings are very dry, high friction the risk is they rotate and if they rotate long and fast enougn they weld themselves to the axle. I have seen this with my own eyes and the damage caused when the repair mechanic removed the bearing with an oxy torch!!!!. Check your axles for scours indicating that the bearing cups are rotating on the axle. The bearings need to be a slide on fit for maintenance and ease of replacement. If this fit is an excessively loose fit the bearings without the spacer and appropiate shims torque correctly will rotate.<br><br><blockquote style="margin: 0 auto; padding: 0 2em; border-left:2px solid #00ADE5; white-space: pre-wrap "><br><br>------ Original Message ------<br>From: "BJ8Healeys" <sbyers@ec.rr.com><br>To: "'Bob Spidell'" <bspidell@comcast.net>; healeys@autox.team.net<br>Sent: Monday, 29 Jan, 2018 At 6:54 AM<br>Subject: Re: [Healeys] Front wheel bearing query<br><br><div class="WordSection1"><p class="MsoNormal"><span style="font-family: "Comic Sans MS";color: rgb(0,32,96);">The torque specification for the stub axle nut is 40 - 70 lb-ft.</span></p><p class="MsoNormal"><span style="font-family: "Comic Sans MS";color: rgb(0,32,96);">My technique for achieving this is to torque first to 40, then continue toward lining up the next castellation with the cotter pin hole.

A hundred or so miles out of town the car developed a loud, grinding, 'squeal' at the right front. Assuming wheel bearing damage, I got the right front wheel up on a jack and did the usual testing. All seemed normal, so I got back on the road and the noise, of course, resumed. A few hundred miles down the road the noise stopped.</p><p>We continued the trip--probably did 2-3K miles--and when I got home I tore into the hub. Sure enough, that washer with the inner tab had spun and turned about 90deg in the direction of forward travel, then stopped (the noise was likely from the washer grinding against the inside of the hub). So, yes, the tabs on these washers can shear and the washer can rotate. I don't recall bearing damage, but I likely replaced both wheel bearings and associated parts on the car whilst I was in there. If your other bearings were in good nick I think we know what caused the problem (it's possible your bad bearing ran dry as well).</p><p>I don't know if this was an original part, or it had been replaced by a previous owner, but I blame the 'usual suspect:' sub-par aftermarket parts manufacture. Also, I think the torque specification for the big castellated nut that holds everything together--IIRC, it's 70lb-ft--is a bit specious, as you have to line up a slot on the castellated nut with the hole in the axle threads for the cotter (and you'll have no idea what the actual, final torque is after you turn the nut to line up with the hold). Since my experience, I always torque the snot out of that nut; i.e. I torque the nut to nominal or, nearly as tight as I can, then put a big breaker bar on it and continue torquing until at least the next slot (or the next, or the next ...). That is a big nut and 'bolt,' it would take a gorilla to snap it off or cross-thread. I've had no similar issue for 100K miles or so, though I just went through my hubs again and a couple of the bearings were worn, but had also been run dry. This time, I sprung for (hopefully) better grease:</p><p><b><a href="https://tinyurl.com/y9ljd69a" target="_blank">https://tinyurl.com/y9ljd69a</a></b></p><p>This stuff feels--for lack of a better word--'slipperier' than petroleum grease I've used. I have high hopes for it.</p><p>Bob</p><p> </p><p class="MsoNormal"> </p><div><p class="MsoNormal">On 1/28/2018 7:30 AM, <a href="mailto:simon.lachlan@homecall.co.uk"><span class="wt_Email">simon.lachlan@homecall.co.uk</span><span></span></a> wrote:</p></div><blockquote style="margin-top: 5.0pt;margin-bottom: 5.0pt;"><p class="MsoNormal">Hi,</p><p class="MsoNormal">Some wisdom from the gurus please.</p><p class="MsoNormal">We’re looking at a MKII BT7 here.
