Oily bits
« on: 23.10. 2018 17:12 »
I've almost finished sorting out the various oil leaks on my bike. The inner timing cover took two attempts. Second time I resorted using 3 bond gasket sealer. However I digress so to get to the point I have a weep from the oil tank banjo. I have tried fixing this earlier on this year, but with little success. Does anyone have any suggestions? I have been toying with the idea of using some 3 bond on the washer faces, what do you think chaps? Presently I have fibre washers fitted, might copper washers be a better idea? Finally can this job be tackled without draining the oil tank down? I am thinking that this should be possible because the return pipe stands above the oil level in the oil tank. Would I be right in my assumption?

I've had experience of the oil tank cracking around the connections. the oil tank mounting arrangement is a bit 'Heath Robinson' and sometimes the pipes get strained because they vibrate against the frame or they are pulling in an awkward position. To be absolutely sure I'd take the tank off, drain it and pressure test it. If all is well you need to make sure the surfaces are clean and flat and make sure the nut is trapping the banjo and the fibre washers firmly.

The fibre washers for the oil tank banjo are thicker than standard.If you have used ordinary fibre washers the half nut runs out of thread before nipping the fibre washers fully.

Yes and I have found they need frequent. tightening over a period of time but do eventually seal

The A7 used to have a small weep around the connections that I was told was caused by a crack. I asked for it to be repaired when the tank was re-chromed in 1984 but I am not sure they did it properly as it still weeps from the same place *cry*
