Take its head off??

<< < (3/3)

Seamus:
More thanks in order. The head will be off this weekend with the barrels. These will be blasted and repainted. Hopefully will also be reunited with a painted engine by mid week. Yhen the challenge of getting the engine back into the frame.
Cheers all

Seamus

Seamus:
Head and barrels came off a treat. Many thanks for the advice.

May as well strip it down and check the rest whilst I am at it. The cases need repainting and that lump is very awkward to clean properly. May as well bead blast these cases and paint when I am doing the rest. I believe that I can remove the crank and gearbox internals by splitting the cases and that I dont have to remove the altenator rotor and clutch.

I think I am getting to be a masochist!!

Still, I have the powder coating back, so some progress

Cheers

Seamus

JonnyB:
just remember to make all the bearing seats so they go back in the same places

Bryanj:
You need to take the pistons off to get the crank out and if you are going that far you need:-

Oil seal set
Cam chain (ALWAYS fit new when crank out) + VERY carefully check the tensioner rollers
4 x piston ciclips (AT LEAST poss 8)
Bottom end gaskets OR complete set in the first place---check if the "PUCKS" (under the cam bearing assemblies) are in the set as a lot of sets dont supply these now for some reason

Seamus:
Thanks folks. I knew that I would have to remove the pistons and the plan was to use masking tape to attach the mains to the crank. (marking them top and bottom)
I have a full gasket set from Dave Silver and I believe that all the seals etc are present. I will have to get the piston circlips as well.
Cam chain is a good idea.

Many thanks for the thoughts

Seamus
