Could anyone confirm what material the two washers are made from on the fiche numbered 12 and 14?

Are they copper?

I’ve new o rings on the back of the caps, anything else I’ve missed? Mine came without both washers so have no point of reference

Help required.

Originally soft alloy between bracket and cam cover, not sure about between bolt head and bracket.
A thick copper will probably do

I'm like Bryan, the underneath washer is definitely a soft alloy one, I tend to fit a copper one under the head of the bolt.

I've got both kinds if you need any Roo. I also fit the same type copper washer under every bolt with a number 12 washer under it as well.

Just started a 550 clutch cover tonight Roo. Went to the box they are all in and just picked one at random, damn it's BAD, really really really bad. Massive amounts of corrosion. Just spend 2 3/4 hours tidying it up a little, did I mention it's bad. Got about 1/3rd done but many many more hours to go on it yet. I've taken some before pics and I'll take some more as it progresses, don't hold your breath, this will be a whenever I feel like it project. Actuating arm is in nice condition though.

Definitely soft alloy. I believe Trigger has a modification to eliminate weeping from this area. I think it involves some machining and the use of an o ring. I’ve not tried the copper washer alternative solution.

[Laverdaroo]

Thanks fellas, mine had absolutely nothing on them and only thought it should  upon having a look last night.

Ken, could you bob some in a bag to suit and fling em in the post mate, that would be extaordinarily useful? ket me know how many camels yuo want and I'll reimburse you .

I'll go with yur advice and do all the ones listed as 12 if you've got enough?


Phil...."I think it involves some machining and the use of an o ring. I’ve not tried the copper washer alternative solution".


What is this weeping problem you talk of??

[Sesman]

Dunno, mate. I think it was mentioned by one of the following: Julie, Delta, Ash, Ken….. I may of course be talking boll£:s.

[Laverdaroo]

highly likely..................

[K2-K6]

For the copper washers, heat to red and quench in cold water (annealing) to make them soft for those that don't all ready know "how to suck eggs" 

Then they'll have the best chance of taking any discrepancy out of the surface to seal it effectively.

[Laverdaroo]

Morning,
Familiar with the heating and qunching but I was under the impression that was for when you reuse copper?
Would I have to reanneal them as they'll be new or are you suggesting doing that as a matter of course?

[Bryanj]

Shouldnt need to aneal new washers mate, and the weeping is because oil feed to the cam bearings is via the ends so oil can leak from that bolt.
Personally after a rebuild i leave the end caps and brackets off until i have spun the engine over enough to see oil come out at both ends, then fit the brackets and covers

[Laverdaroo]

I thought so but K2K6 threw me a bit there with his post.

Thats the plan Bryan, I'm just making sure I have what I need to get the engine back together after the spin up and just want the right kit as and where required.....as yer do!
. When I saw them I new there should be some form of seal behind etc and remember speaking to you about it earlier in the year mate, washer,  there wasnt any on there as I said earlier hence the question. TBH, there wasnt much of anything of any use realistically
