double roller timing chain

[BLUESMOKEGTP]

Installing a new rm double roller and speaking with the guy at zzp he says no need to chamfer the crank gear. Truly how true is that. Jus add the machined cover n thicker gasket and I'm good

We should make a section dedicated to double roller threads

Lol... There'd still be the same questions!

OP, have you searched the topic? Is your crank gear pre-chamfered? Omg... And seriously, you ask the person selling you snake oil if it'll make your hair grow back along with make you rich!?!? Lol

lots of people dont do anything to the chamfer and are fine, other people are uncomfortable with the fit and chose to have it chamfered to match the stock crank gear. personally, I would rather have a proper fit and not have to worry about the offset that will occur if its not machined

you don't need machined cover and thicker gaskets just run double paper gaskets but use some gasket maker between the 2 layers thats what i did with mine and it works fine

I had GR8racingfool chamfer mine as my local machine shops wanted to know the metal grade and strength. I will also be running the machined oil pump cover and 1 genuine gm front cover gasket.
