Banjo bolts

[nudemetalz]

Greetings,

The NZ-250 motor is together now and the head gasket appears to be leak-free (so far).
However, one of the external oil line banjo bolts appears to be leaking. I have it torqued as per the manual.
Question is, so you have to replace the washers every time the bolt comes off?
Can I use some sort of sealant in there to stop the leak?

(okay, that was 2 questions)


Cheers,
Chris

shouldnt have to replace washers every time.

dont worry so much about the torque, thats to stop dimwits overtightening stuff and breaking it... if you can tighten it a bit more without using the arms of hercules it may stop the leak, in saying that correct torque i assume would have stopped it.

Maybe sealant is the key, but wouldnt know what to use.

Thanks Gareth.

I always get a bit hesitant with tightening big bolts a bit more into an alloy casting, but I might just nip it up a little more and see what that does...
(I might end up with a total-loss sump.....)

You should replace the seals they are cheap compared to trying to repair a stripped thread (imo)... A lot of 2 strokers use dowty seals for this reason,they are reusable and take little pressure to seal...

Edit... Well you don't have to change them,but something like a oil feed,you don't want to be worrying about when you are riding..clean surfaces,new seals,torque it up and forget about it...with only the usual routine check over before a ride.

I guess there is a fair amount of oil pressure going through the banjo's (the NZ is air/oil-cooled like an early Gixxer) and it only takes a little gap.

I'll stop off at the shop and pick up some new seals me thinks.

Thanks for the info TLDV8

I came back and done a edit and noticed you have posted while i was doing it...the Yellow TL in my profile pic was stripped to pretty much nothing...then a lap of the block,followed by a Coro loop ride,mid week with no phone,the first 60 kms was spent thinking,did i do every thing up or miss anything ...it's just nice to know something is reliable,its normally the little things that let you down.

What are the washers made of? If they're copper or aluminium, you can 'freshen them up' by heating them heaps then quenching them. But if they're not hard to get hold of or toldlessly expensive, new ones are a better bet.

They look like copper to me. Guess they need to squash down to seal well.

I pulled off the oil-line again last night and cleaned up the washers and bolt. Did it up and torqued it plus a little more. Presto !! No more leak !!

I (actually the Missus) also found the little spring pin for the neutral indicator switch that I had lost so now the green light works again !!!

All is good !!!
