CYLINDER REBORING/ COATING

[Banter]

Apologies if this is a dumb question but why do you need to replace the coating, why canâ€t you just hone the bore out and replace with over sized rings. Is it that the metal under the coating is to weak or of a composition that requires the additional friction decrease for heat dispersion? I have read all the benefits in the ads and manual but whatâ€s the cost to benefit ratio and can you get away without it.

The bores are lined with a ceramic type of compound over the aluminium cylinder,the lining is only about .002"-.005" thick and the aluminium underneath is not durable enough for long term use on its own
i have heard of some just using the aluminium, but its only in race use and the cyls are a disposable item with a set life in this case.

Hi Maj, thanks for replying, I went to the site http://www.mt-llc.com/ who had some detailed videoâ€s on Nickel Silicon Carbide plating, amazing stuff. Not to mention the honing and correct ring types in spring strength, surface and so on. MT have only released 2 videoâ€s so far, canâ€t wait until the next one. Iâ€m also finding tons of stuff on the net but I donâ€t get the spring tension on the ring. How can the ring bed into the bore correctly if it cant cut into the hone pattern because the surface is so hard. I have read a little about chromed rings but it still seems a bit hit and miss! Anyway Iâ€m sure it will all make sense eventually. Thanks again for the reply.
