Oil pipes tank to engine

(1/3) > >>

SteveCR7:
I am restoring a CB750 that has stood for many years. The oil tank contained oil so wasn’t left dry. Can anybody tell me if the oil pipes degrade internally over time if the oil is not circulating for long periods. I am assuming there is an internal rubber hose and I don’t want to find this is disintegrating and blocks the oil ways.

Thanks Steve

MrDavo:
They can collapse internally, with obvious results. Somewhere on the forum is an old thread on my CB750 which had oil pressure issues, I started with the hoses. (And ended up changing the crank - it's a long story). I got new ones from Germany, via eBay.

After two classic Honda restorations I've come to the conclusion that anything old and made of rubber should be treated as scrap.

Steve - get them replaced 100% if it's sat for a long time and you're suspicious. There's a chap in Germany who sells re-conditioned units (much cheaper than DSS). Think I've shared his details on the forum somewhere? (sorry don't have them to hand now).

SteveCR7:
Thanks for the advice guys I will check out the guy in germany

Hi Steve,
I replaced my hoses last year at our local industrial hydraulic repair centre "mend-a-hose" they just replace the pipe and crimps onto the existing castings. They look great and very good value compared to DS parts.

James gave me the details of the guy in Germany (if the look of originality is important to you), I will post on here as soon as I locate them.

Cheers
Rob
