I'd have asked why they hadn't come round with it when they knew it wasn't theirs.

Hi Guy`s

Just an update on the Bomber, well the parts came from Dave silver so I made a start this morning took off the rear Mudguard and the rear wheel and got the shaft out only to find there was Not much Grease in it what so ever, anyway the bushes looked ok so I done what Ashely said and the New old stock Collar fitted in a treat with No worries. so put all new parts in ( so got a new set of bushes for spare ) fitted it back in the frame and there is No Movement from side to side Now so all good,

and the up and down is nice and smooth too. I found out also that the Grease Nipple was Not letting any grease go in though the shaft so heated that up with a blow lamp and cleared that all out just need to force some more in to make sure that the cavity is all full up unlike it was so must have been why it got worn in such a shout time as was only done about 3 1/2 years ago so the bloke said who i got it off.  and it had only done 1,500 miles....... but ha Ho all done now.

Happy man

Mo

We discussed on another thread about lubricant, specifically grease type with some consideration to use a black molly CV type grease in these.

I'd favour that as properties of very high resistance to pressure and normally sited in limited use / movement type joints.

May want to consider this, I use it also for headstock bearings. Highly resistant to being displaced and hugely repellant to moisture etc.

I feel there's good evidence (significant thread of discussion on here) to use a modern synthetic in these engine. 

Concerns about camshaft longevity, supply to that location and the heat with consequent "clagging" in the high heat crankshaft oil passages, then coupled with oil pump type, all have the potential to be helped by one of these oil types.

No its not because its more slippery, but much more about consistency of viscosity and pace of flow given the architecture within it, that's in my view  :)

Nigel,
Interesting about the oil....although this tread is in danger of massive drift!

Do the 250/350/360 engines fall into this synthetic oil category that you are suggesting.  They are very similar as I understand.  Can you pint me to the thread please.

It's this one Jerry http://www.sohc.co.uk/index.php/topic,14515.0.html there's some intriguing and very in depth record from Jensen in running his 450 over extended period.

I do think the twins generally are in the same category with regard to oil, yes.

Probably because early twins were all roller big ends not shells

Nigel,

That was a long read and some of the stuff went in, but some went through!

The thread is quite old from 2017.  Just wonder what the outcome was....or did I miss a link.

I do know that when I tried a 10/40 on my CBX many years ago.  I had to drain it fairly quickly as to use someone's quote, it was making a bid for freedom out of every seal/gasket.  Returned to dino and it all dried up.  Some comment on using it with new seals and gaskets only makes sense on rebuild though.

Cheers,

"Returned to Dino" Love that quote, so descriptive.

Lots of comments about leakage using fully synth in old machinery, semi less leakage but is it worth the risk? Might as well stay with Dino oil until it's not practical anymore IMO.
