I think you left something out there.
I have downloaded this for future use. I think I will do mine the next time I replace the belts, just in case.
BTW: What's the current recommendation for timing belt replacement interval? My FSM just says to inspect and replace if you see wear and the Owner's manual doesn't mention them.
I guess I just assumed you could read my mind... "Grind or machine stepped."="Grind or machine a cylindrical step on the underside of the head to 14mm diameter with about 4mm (or less) depth leaving some of the original material."
As for frequency of belt replacement??... I am sure you can find lots opinions with a search... The only "official" statement by Mother HOnda was for the GL1500 and they said to "inspect" the belts at 100,000 miles. Having said that, there are lots of automobile manufacturer recommendations, for example, Toyota (e.g., that uses the same belt for the SR5 as the GL1200, i.e., the T070) recommends 60,000 miles... As a happy medium, I generally tell people 8 years or 80,000 miles.. but in my opinion that is probably still conservative... I am convinced that more people damage their engines by improperly installing belts than by having them break (or wear out)...Jim
