Newb here,been studying and watching everything I can about re-assembling this TR7RV engine.I don't want to make any mistakes or miss any steps. Any assembly tips, help offered will be read,remembered and appreciated. I also got a gasket set and not sure where every rubber ring goes. Is there an exploded view link available for triumph 650 750 engines?
I tore the engine apart last year.Finally got the parts to rebuild.
I had theses jugs measured and was told it's .020 over stock.
I bought the Emgo pistons and they do say JCC inside.
I got the matching Emgo ring set also with them.I have never set gap on rings before. I read posts on here where they said emgo rings are junk and too big of a gap.These do not seem like they will cause that problem.
they fit very tight in the jug.I also have a question about my push rods.do these all look useable? why is one tapered on edge,and why do 3 have holes in the cup?
and two holes in the tappets the cam pushes up to push the rods.I guess it's for oil, but why not all four?now looking at the pics it seems like wear. one has copper looking tips.My first big question, does this cylinder wall prep look good?
Should I have been hoping for more of a cleaner, no vertical lines, cross hatch look? I really don't see much cross hatching.I saw on youtube Lunmad using sandpaper, don't remember the grit.
I cleaned the case surface and it still has a black stained look on the surface.What should I do to make the surfaces seal correctly?should I keep the gaskets dry when I assemble? or use a thin coating of silicone I saw someone use. and if so, what brand,color and style silicone do I look for? I heard a few times "install the pistons dry".The 3 piece ring on the bottom of the piston seems too wide to fit in the bottom groove on the piston.two will fit.I don't want to try and force it in and damage the new rings. are they squeezed in?
As I took pics I figured it out.Put the bottom and middle part on, then the top. I'm sure I have more q's as I go, but these are some things weighing on my mind as I realize success is all about correct assembly procedures.It's been three years in the making and I want to ride this bike until the end of time. I think most mechanical jobs seem tough until you do it. With a degree of parts ,tools ,knowledge(that's where you come in!) and error. I already know more about this machine than I thought I ever could. It's my first ring job.Probably not my last.Where should I place these gaps on the 3 piece ring? I read about staggering them. But these go opposite? or is this correct? I know they will have to come back off for gapping.I wanted to see if I could get them on.
Thank you for any help.I know,being this green. Get a friggin' manual! Sometimes a person will give better tips and knowledge than a manual.I know some of you guys lived inside these engines for years. I want to get there also and know every nut ,bolt and part in there and how to inspect,prep and install them. If I do get a manual, what is the best one to get? As these q's are answered,they will be here for all to use.That's what this site is about.Sharing knowledge.If I can answer anybodys q's in the future, I will be glad to.Thanks J.J. ! Tom Mitchell.
