Piston Rings

[Judderi]

Whats involved in re newing them and will i need to remove the whole engine or need any special tools?

[takethefifth]

Good question!

And if i may add - would it be worth doing your stem seals/seats at the same time as i assume you'd have to take the head off......

I think its almost time to attempt to sort my oil problems as well but i reckon rings on a car are going to be a bit more tricky than on my 2stroke trials bike! 

[Judderi]

Well you could come help me do it then i could come help you do yours.

[takethefifth]

Now that could be a plan, give me a shout when you decide when you fancy doing it! 

[Judderi]

Will do. Your durham way arnt you?

Nr Richmond, past darlo straight down the '66 

So yes anybody done piston rings before? 

[...joe]

yep, but i had my engine in pieces when i did it!

i believe you can take them out the bottom after removing the sump? but ootherwise its head off, sump off, etc to release them from the crank so you can pull them out the top.easy enough but lengthy.

[Gambit]

you can do it with the block in situ & the head off. just take the sump of and dismantle from the bottom

worthwhile doing the big end bearings at the same time

make sure you mark each rod, casing, piston. infact mark everything piston 1,2,3,4 everything is balanced so if you mess it up refitting u'll have even more probs

u need to hone the bores and u also need a ring condenser for getting the piston back into block

[Judderi]

What do you mean by hone the bores?

[Judderi]

Also im thinking of getting the bottom end lightened and balanced. Should i just leave the piston ring replacement up to the people who do the lightening/ballancing?
