I guess after fabricating half the car’s body shell from scratch the next logical step is to move onto building your own engine components 😉. Seriously though if it can be done it should give you an engine that you have confidence in as you know you’ve sorted all the issues, whereas another replacement engine may have a whole new set of issues waiting to be found. captain_70s and rml2345 2 Link to comment Share on other sites More sharing options...
captain_70s Posted August 20, 2022 Author Share Posted August 20, 2022 Silver Sharpie grille restoration. To celebrate my neighbour reversed into the car while parking. I was digging stuff out of the boot at the time, she dashed off inside without saying owt. No damage, the joys of keeping a car on a public street... I also got the Volvo's tracking sorted. Finally. Next jobs are the Acclaim's rad and timing belt. @GingerNuttz has been modifying/upgrading his CNC to start thrust washer production and is pretty much there. Hopefully it'll be back running again and I can have another 300 miles of being a rolling roadblock. 👌 Lacquer Peel, Datsuncog, LightBulbFun and 35 others 38 Link to comment Share on other sites More sharing options...

captain_70s Posted August 21, 2022 Author Share Posted August 21, 2022 Our working theory is that anything that is tougher than bronze but softer than steel should fill the role of thrust washer without any negative effect, provided it doesn't have some stupid low melting point. I'm guessing the failure of the shimmed thrust washer was due to it being forced into constant contact with the crank due to warping shims. At least that's the only way I can think of that it'd have worn so much in 300 miles. With thrust washers made of a solid wear material of tougher stuff they should, in theory, have a very long lifespan compared to a sliver of bronze on a steel shim. With the bonus that there won't be a point where by the bronze is all gone and you have steel on steel, at least not until the thrust washer is entirely destroyed or it falls out.

Dave_Q Posted August 21, 2022 Share Posted August 21, 2022 I'm not sure on aluminium for bearings, yes it's hard/strong enough but aluminium has quite a high coefficient of friction compared to steel/bronze/etc. I guess this is provided with oil so when running nae bother as it's on a film of oil but start up and shut down could see higher wear? I'm assuming it's not that difficult to change if it goes wrong but I'd vote for solid bronze for the first try if you're going to that effort.

captain_70s Posted August 21, 2022 Author Share Posted August 21, 2022 In theory it should float in a film of oil and not really contact anything with any degree of force until the clutch is depressed and puts a significant horizontal load on the crankshaft. For this reason I've been quite careful to not hold the clutch sat at lights etc. You can replace the thrusts with the engine in the car. Empty the oil, drop the sump, end cap off, prod the old washers out, post the new ones in, reassemble. So even if the aluminium does wear overly quickly they could be changed in an hour or so, the main priority is making sure the crank doesn't get chewed up. I'll be monitoring the situation with periodic tests with a dial test gauge against the crank pulley. davehedgehog31, juular, Jenson Velcro and 2 others 5 Link to comment Share on other sites More sharing options...

I'm assuming it's not that difficult to change if it goes wrong but I'd vote for solid bronze for the first try if you're going to that effort. I was also wondering this and also aluminium has a much lower melting point doesn't it? I don't think the engine would get hot enough for them to actually melt but they might get a bit soft. I mean if they were sufficient why wouldn't they use it originally, it would be cheaper than the originals. But as you say they are quick and easy to change on the Dolomite, unlike on my 1300TC which would be an engine out job, and being softer than the crank shouldn't damage it so I guess it's worth a try.

rainagain Posted August 22, 2022 Share Posted August 22, 2022 A few of the engineers where I work build racing engines for motorcycles. If you give me the dimensions of what you’re after and the material choice I could ask them for a cost machining one for you if it helps. sdkrc 1 Link to comment Share on other sites More sharing options...
GingerNuttz Posted August 22, 2022 Share Posted August 22, 2022 6082 is structural aluminum so it should be ok, I can cut him 10 at a time so he's good for 3K miles between me needing to cut more 🤣 davidfowler2000, Split_Pin, rainagain and 5 others 3 5 Link to comment Share on other sites More sharing options...
