Cylinder Head

Post by BeenyBoy »

1965 G2csr

Please can you tell me if there are 5 bolts securing the cylinder head ? There are clearly 4 sleeve nuts set in a square and a 3/8" hole to one side. However the manual suggests there a 5 bolts in total but I am unable to find one in the box of bits- assuming there should be a bolt here what size is it- I guess its 3/8 26tpi (???) by 3"

:? :? :? :?

There is a bolt just inside the rocker box cover, near the oil way hole, if memory serves me right it's 5/16 BSF but the length evades me, maybe 2" long,

People with far more knowledge than me will be along to put you right soon.

Kind regards Colin

Thanks Colin- I'm asking about the Cylinder head to barrel joint....I've found a bolt in the box of bits which looks close but its clearly not the right one as the head is pitted and rusty

If you look at your spares book it's part number 042196 Bolt cylinder head 5/16 x 22, it is also shown in the engine/gearbox exploded drawing.

I think this is the bolt you are looking for.
