If you use clear tubing instead of black rubber, it's easy to check oil flow.

Hello, can someone please confirm which way I should be fitting my short section rocker oil feed banjo 42-0139 onto the oil tank on the 1958 GF. The banjo has different diameters on either side - do I fit the smaller diameter against the oil tank and the larger diameter against the stepped nut or vice versa?
Any comments much appreciated.
Many thanks.
Peter

I was told a long time ago to occasionally put a finger over the return in the tank to send more oil to the rockers.. maybe a load of xxxx but i have always done this (before the oil gets too hot) mind I have only had the bike for 52 years so still on a learning curve!!!

Just a quick question.  I'm sorting the connections for the new maggie cut out oil switch, and thought I'd try to locate the weeping oil from somewhere around the tank connections.  On the return side banjo, I have an annealed copper washer next to the tank, and a fibre washer behind the nut that holds it all on.  When I screw on the return oil pipe, there doesn't seem to be any room left when it's tightened, and I'm wondering if it's bottoming out on the large banjo nut.  Once tightened, the oil pipe spigot doesn't move, but is the setup correct?

Cheers Billy (and Andrew).

There was a copper washer next to the tank which I thought was standard.  I'll change it for a fibre item (which should be a little thinner) and see if that makes a difference.

I've managed to solve all my leaks, at least for now  *roll*

I used fibre washers as per the diagram.  Just be aware Worty that not all fibre washers are created equal in thickness and fortitude it seems.
Try to find some good old school thick ones, I'm sure they are better.

Correct, the fibre washers sold by MCA are generally very good and just like the originals. With them being thick, it is necessary to tighten and retighten periodically, particularly the notorious rocker banjos.

Am I right in saying MCA only supply trade these days?  If so, who is a reliable supplier?

 Just chose your most convenient bricks and mortar bike shop. The likes of MCA,  Wassell etc  will sell to them no problem. Standard bearings, oil seals and other engineering sundries, like fibre washers can be sourced from a local bearing supplier, or if they insist on account holders only, via any established retail enterprise such as your local back street garage.

 If  price is your consideration, online will be far cheaper, but the uncertainty of quality may make it worth paying a little extra for stuff you can see and handle before parting with your cash.

I've swapped many of the fibre washers for annealed aluminium ones. They are a single use (although with care you can re anneal them) but they are brilliant at sealing problem unions. My 58 Rocket has a top end feed exactly as the 58 Parts book which is given the parts no. 42-48 (or as Feked has it 42-0048 two banjos a tee section and a long steel pipe with a short rubber join near the oil tank return. Probably all been said already but that's forums for you.

As per above posts I was convinced I had solved all my RB oil leak issues...A year later and for the last few runs I've had an ever worsening recurrence of the dread Oil Leak   *sad2*

Thing is only on the left side of the head in particular filling up the counter bore for the head bolt immediately below the banjo and the RB gasket looked good all around the joint. Checked the easy and the obvious first before giving in and stripping it all down again and Lo! The banjo bolt on the exhaust rocker feed was loose and I mean not even finger tight  *eek*

Needless to say everything has been nipped up once again but I'm thinking these fibre washers are a dead loss and I might try Slymo's idea of Aluminium ones if this happens again (and it probably will)...
