I think I have cracked it by fitting a different spring.
After rummidging through my bits I found an alternative, possibly from a tiger cub.
The hook on the spring plate didn't look the correct shape, so I heated it to red-hot and forged it to a better angle.
Haven't checked the action because of a clutch issue (clicking) which needs sorting.
Trying to add an attachment but when click preview, nothing appears... why is it so difficult to post pictures?

Thanks Bess, different to mine, my spring has 4 coils and the anchor peg is at 9 o'clock.

Thanks Julian, as the pic shows, the spring is of a different type, this the same as my workshop manual, wrong.
The spring in this pic shows a long leg slotted into a hole, in a lug, which is a part of the inner G/B cover.
I believe this type was fitted to singles?
The spring 68-3053 has two loops, one (inner) for the anchor peg (at 9 o'clock) and the other for the spring plate 68-3054, which sits slack at about 6-7 o'clock.
The spares book shows this arrangement with the spring plate hook/lug facing outwards at 12 o'clock, presumably when fitted.
I am unable to find any pictures of the spring and plate actually fitted.

Well, I don't know if pre-OIF A65's are different to OIF models, but the retaining washer hook should be at the top on my '71, according to the spares book.
Maybe I have the wrong washer or it's damaged in some way, but it wont fit with the hook at the bottom because it fouls the case.

Yes, bought one just for this job.
Trouble is, the spring distorts and the shaft rotates.
I can get the tang to vertical using a spring puller and screwdriver and tieing it with rope, but when I remove the screwdriver the spring jumps off the fixed screw.
Tried string but it snaps.
I'm using a hose clip to hold the tang plate against the boss.
Even tried rotating the tang plate engaged to the spring to no avail.
There must be a knack that I'm missing somewhere or maybe it needs two people?

OK I give up.
What method do you use to fit this spring, been struggling with this for too long?
There is a video on youtube, but he has fitted it with the tang at the good.
Even if fitted it with hook down, there would be very little tension and the tang fouls the case anyway.

Well my '71 was in a bit of a state.
l sent the head off to be completely overhauled with new valves, seats, etc, to The Cylinderhead Shop.
It needed a re-bore. new pistons, rings etc.

Thank you, will do.

Thanks for your reply Julian.
I can feel the spring when pushing the shaft/pinion inwards.
But, the cam pinion is slightly out of alignment with the idler pinion.
Should the pinion be in contact with the bush outer or should there be a gap?
I`ve a feeling there should be a small gap because if its in cantact it would get hot and wear.

There is no torque figure for this nut.
How tight should it  be and how much float?
At the moment I have about 1/16th" lateral movement.
I had to manufacture a woodruff key, because the keyway is 5mm wide?
I think I over-tightened it, the first time and it became solid.

Armours' used to be very good, qualitywise and service.
Unfortunately the service now poor.
I filled my basket with downpipes, clamps, etc.
I was sent confirmation of my order, with a note saying the invoice will be sent later. (just as well it wasn't urgent.)
A few days later, I recieved the invoice.
So I thought I should 'phone to give details of payment.
Nine times, it was either engaged or I got a silly message telling me to go to their website.
I sent an email to the sales people, who replied with a message that I should click the 'pay now' button, which is non-existant.
After another couple of emails it was pointed out that if there is no button, I should telephone.
You can guess what happened!
The one telephone number is only available Tues to Fri and not during the extended lunch break.
Very poor in my opinion.

Twins / Aftermarket oil filter
« on: 18 April, 2017, 12:05:52 »
I did a few web searches about oil filters for our old bikes.
Specifically for which line, inlet or return.
I have already bought a Champion filter.
Depending on the bike manufacture, there is confusion!
Most say the filter is in the return, but others say the feed.
The ones that say the feed-line, explain that the return is pulsing and aerated, which can damage the filter material.
The others for the return, say nothing should be in the feed side.
So how about my OIF A65L?

Additionally, this bike was fitted with an oil cooler. (U.S. import)
Is this rerquired for here in the UK?
