Engine full of fuel and seized up

<< < (40/50) > >>

Greg65:
A light deglaze with one of those glaze busters or a very light touch with a 600 grit honing tool should suffice. Seeing as the engine is split have you had the bores measured to check their in spec and don’t need a rebore and oversize piston? Hope I’m not creating more expense,

Cheers,
Greg

PJM47:
Can I measure the bores myself with the right equipment? I prefer to invest in tools and learning rather than get someone else to do things where possible. Visually the cylinders look in good shape though.

Bryanj:
To do that you need a bore gauge and a 50 to 75 outside micrometer both can be got on ebay for about £30 each for chinese made ones, better ones, starret/mercer/moore and wright cost more

PJM47:
Ta, the bores are in good condition no sign of scoring or lips where the pistons end so should be ok but I will check anyway.

On to the main bearings, please could people advise on whether they think these should be replaced, I know not easy to tell from the pictures. Any help appreciated as always.

Worrying one to me is the near centre one in the top case which looks very scuffed, others look slightly scuffed but usable, personally although its not cheap i would replace them all you jest need to read the codes on the crank and crankcases.
Considering the marks on the mains i think its worth splitting the big ends and inspecting.

Its all work and more expense but these motors need doing right
