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.
If you like long stories you could view the update here:

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.

Thanks chaps, return it is :)

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?

Thanks again for your advice.
I really can't remove the spindle again.
Medical conditions make certain tasks difficult, I had to take the pump to a mate in a garage to remove the circlip, which even he struggled with.
I wasn't trying to be a cowboy WRT the turning by drill, it just occured to me that if it goes back in its present state, that is what will happen.
As you appeared to be saying, a little tightness could be alright, but any body lapping is out of the question, I think it will be assembled "as is".
Its going to have an oil pressure gauge on completion, so I can monitor the pump efficiency then.

Thanks for the reply Julian.
Its a zinc type..
There is a little spindle 'end-play'.
Turning by screwdriver a few times, (with the oilways full of oil there appears to be a slight 'high spot' at a certain point.
Oil gets pushed out of the top holes, I presume the lower ones suck, because the oil disappears.
Maybe I'll remove the four base screws and try turning again.
Other than that, I could use a drill to give it a bit of run-in?

1971 A65L
I bought a new spindle for this pump because the old one had chipped and worn teeth.
After disassembling and cleaning, I find its a little tight to turn.
Maybe it will be ok after its 'run-in'.
It will turn using a screwdriver, but not using my fingers.
Is this normal or should I take it apart again?

I bought this tool because mine is a '71.

Thanks for the replies everyone!
In essence my original plan seems OK.
Final assemble nyloc nuts and plain washers.
If I'm allowed to mention Triumph, my Bonneville uses mainly bolts screwed into the cases.
Where there are through bolts, it has plain washers and full nuts.
The difference in my 1971 A65L is that the cases use a majority of studs and nuts.

Hi Bess

Thanks for your reply.
This topic about locknuts seems to have been going on for ages.
I think plain nuts is the way to go for (temporarily) for this job in hand.
I'm not too keen on spring washers either.  Or metal locknuts.

Obviously I dont want the case fasteners to loosen, perhaps I'll use nylocs plus plain washers and see how it goes in the final assembly?
I was just wondering if anyone has bad results with them.
Vibration, etc?

I am just about ready to put the case-halves together with the crankshaft to check the end float.
I am aiming for .002" float, using two .0045" shims, giving .009".
But there's a problem!
All of the case nuts are 'locknuts', some with spring washers.
Having read lots of stuff about locknuts, it appears that metal locknuts deform the threads.
As these have to be undone and re-fitted, its not a good idea to torque them up and undo them.
These can only be used once?
So I'm thinking to temporarily use plain fullnuts or nylocs.
And why not use nylocs anyway (once) instead of metal locknuts?

I read nylocs can be good for 250lbft torque and must be used with SS, but not used on exhausts, etc.
Some say use nylocs everywhere instead of metal locknuts?
Opinions welcome!
