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.
Confused?
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?

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?

Hi

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!

Twins / Re: 1971 A65L Drive side thrust washer

Twins / 1971 A65L Drive side thrust washer
« on: 25 March, 2017, 15:34:46 »
Hi
There is a circular raised portion on the crankshaft for the thrust washer to fit over.
How high should it be?
I've a feeling mine is worn, the washer doesn't really want to stay put, which makes assembly of the roller bearing, etc. difficult.

Twins / 1971 A65L plain main bush
« on: 19 March, 2017, 16:17:56 »
I have two choices,
 1) use the old bush that is already fitted or
 2) fit a new one.

1) The journal is half a thou undersize giving .001" clearance with the bush. (top limit?)
According to the book a re-grind is neccessary when the journal is more than  .002" under.

2) Remove the old bush assy. and fit a new one.
How much would a new crush after fitting?
It may need machining.
What about alignment with the opposite roller bearing?

Any recommendations?

Regards
Caulky
