I don't think I see the painted marks on the cam gear. There is what looks like a painted tooth and some paint on the crank gear about where the cam gear rides. The only cam gears I have seen have 2 teeth painted.Charlie?Tom
I appreciate your understanding. Fortunately everything on this bike has come apart cleanly... so I was probably more resistant to pushing my luck this time. Hoping it all goes together as well!
Go here and scroll down. There is a picture of the paint that would have been like my Eldo and Ambo.https://wildguzzi.com/forum/index.php?topic=99057.0Maybe there are different ways of marking?Edit: Look close at "Your" cam gear. In Your first pic it looks like a touch of paint about 12:30. Almost looks like a center punch mark there as well? If you look just on the crank gear, there looks to be paint about half way down on the left of the painted tooth.Maybe those are the marks?Tom
Sorry, I haven't read the whole thread, but before I do *anything* having to do with timing, I put the left (S) cylinder on TDC ready to fire. If you have already done that.. "nevermind.."
I did on my 73 and gave me great piece of mind, especially when we found this.
...and what is that?
Delta Camshaft in Tacoma, WA can reface the lifters for ~ $5 ea.
No no, as Charlie said, 26mm. With that said, I use the same as my axle nut size 27mm. Seems to work perfect for both.And congrats on the family bonding over a bike!Tom
Cam followers can be surface ground, crank can be mixed and if need be reground, oil pump shafts and casting bores can be mixed for clearance spec and you could get the cam reground to a performance spec if you choose.
So take that pump apart and measure the shafts and the bores for the shafts?
Yes, the shop manual for the V7 Sport lists the shaft and bore measurements / tolerances. A worn out pump, low oil pressure, will negate all the investment you have put into the bike. Most of the non filter Guzzi engines I have rebuilt had worn out oil pumps, V7 Sport, 750S, a couple Ambassadors, Eldorado, all had sloppy shafts to pump body.
Whats the best tool to measure a bore that small? Will a digital caliper fit in there?
The holes the gear shafts run in can be measured with a telescopic gauge such as these:https://www.zoro.com/mitutoyo-telescope-gage-127-19mm-155-128/i/G0970938/and a micrometer. The shafts and gears are measured with a micrometer also. The depth of the pump body is measured with a depth gauge.
A guy once asked me what a micrometer was and did he need one. I told him if he didn't know what it was, he definitely didn't need one. Harsh, but true. Take that stuff to the machine shop. There is skill involved in using mics and definitely depth mics.
Yeah I know what one is but still gonna run it down to the machine shop. Bringing them new valves and guides and clips anyway.Thanks for the advice!
Also... it still had a leak that appeared to come from the rear main seal, but it had been replaced and looks good(Gonna replace the bearing and have new seal so doesnt matter). But someone mentioned other things to look at inside the bell housing that could be the source of the leak instead... breaker tube? Anything else in there I should check or reseal?
