Re: Fiat 50 c crawler info

P.S. I believe there's a mob in Brisbane near Sandgate/Zillmere that do head gaskets also, via CNC.
Thanks for the contacts, though, I appreciate that.

Re: Fiat 50 c crawler info

Thank you once again, Deas. The broken head bolts all have a bit of their steel poking up- none are in a hole as it were, but all are way down the bottom of the water jacket part of the ' engine block. Access is pitiful. The cylinders are a kind-of cast sleeve which sits on the bottom. If we could e...

Re: Fiat 50 c crawler info

P.S. four head bolts have broken off down 'inside'...
They tried welding a nut to one, but it was too close to the edge, or to the sylinder sleeve (I haven't checked) to get a socket over it.

Re: Fiat 50 c crawler info

Thanks for the extra help. Nick has the pistons out-there are two broken oil rings, and one broken compression rings across the four pistons. The vrankshaft is still on/in, at the moment. The engine/block is off the crawler now, and standing up on a pallet, sitting on the flywheel end. We're trying ...

Re: Fiat 50 c crawler info

Thanks, Jeremy - but these particular ones have thread at BOTH ends, and no head. The bottom end is a M16, 2mm pitch thread, which goes into the bottom of the block, and the top end is an M14, 2mm pitch, onto which the brass 'acorn' nut is done up. They look like they were turned on a lathe, actuall...

Re: Fiat 50 c crawler info

Interesting day... The fellow from South Burnett Machinery, the gurus for Fiat parts rang back to say he'd called all over Australia, and there just aren't any parts available that we'd like in the head bolt & head gasket department - in fact no one had parts that would suit it. Nick managed to ...

Re: Fiat 50 c crawler info

Thanks, Deas. We appreciate the comments. What is special about using a spring washer, rather than a plain mild steel washer, in this case, for the welding up to attach a nut? At the moment, the broken studs have WD40 soaking over them & some of the muck has been vacuumed out, but we can try ace...
