Banjo bolt replacement

Hey gents, I need to replace a banjo bolt on the engine during a rebuild. It is part T1210242. A local shop told me it is an M6x20 banjo bolt that can be purchased at any fastener shop. Reason I am driven to that is it is a $10 part and it would be $20 to ship it to me.

Can anyone confirm these can just be bought generically? Further question - has anyone replaced their carb boot clamps, if so, with what?

Cheers!

If I were in your position, I'd certainly buy the generic part. You'll know soon enough if it doesn't work, but I don't see how it couldn't if it's the right size. It's only a banjo bolt, not some exotic part.

You could source your own, look for clamps with a 50-70 mm diameter range and 9 mm wide, preferably in stainless steel. It's a standard size.

Heed the advice of @PieMan in post 2 of this thread as regards tightening:

Mine are about 10 years old so was looking at replacing them simply as a safety precaution while I had them off. Is this necessary?

If you mean the clamps, no. What would be wrong with them?

M6x20 banjo bolt
Where exactly is this banjo bolt located? I've never heard of a M6 size banjo bolt.

As for manifold clamps, make sure they are NOT the perforated type (row of slots punched in the band) because the sharp edges dig into the rubber. These are NOT perforated:

There are 4 M6x20 Banjo bolts altogether.

We've got two of them under the cam cover. They're used on the oil feed to the cams, see items 9:



Another two are on a small pipe linking the oil pumps, items 10 here:

Well, that explains it. I stay away from 'inside' the engine.

Just remember that what makes the banjo bolts work is the copper crush washers. Seals em up tight.
