So I had bad, but good news. I had removed the oil pump as I thought I needed to clear the gears while removing and installing the crank. Well, I didn't have too. I just needed to remove the gears on the crank which had to be swapped over anyway. I didn't realize you only need to remove two long bolts to get the pump off. I removed all 4 and the pump came away in pieces. It was actually a good thing as it was somewhat scored. Weird, I've never run low on oil and pretty good about changing the oil.






I've got two numbers for the pump though, 26357-02B and 26357-07. I'm not sure which is right. Gotta get me a parts manual.

This is great stuff, vtwin.



Need to split the cases on my S2 to re-seal the front of the case (weeps oil at higher revs) and these photos, though different, will be useful for me.

Thanks!

junk from the crank bearing failure?

also the chunk of the adjuster shoe probably came out with one of your primary lube changes.

I've got an o-ring sitting at home. I'll get the part number tonight if you still need it.

Could very well be, although not much debris on the magnet.

No worries, getting a new pump instead and it should come as a complete unit. But thanks.

Well, got ambitious after work and thought I'd work on it for an hour, turned into three!

Put the pistons onto the rods....



Book says to use new snap rings, I did. Don't want them popping out and scoring the cylinders.







Now for the rings.

Time for the cylinder.



I'm only doing one at a time, gotta break it down in chunks. Cleaned the surface with this. My adapter doesn't quite fit it.




Since I've got a new honing tool, better clean up the cylinder.





Not perfect, better than it was though.



Surprising I couldn't get it all out. Bike wasn't using any more oil than normal and I never let it run low, weird. Wonder if it was an oiling problem?

Dropping the cylinder down on the piston #1.



I forgot a step that comes into play later on.




Time for work on the head.




I have new stem seals, may as well replace them. Seat looks a little nasty, a little grinding compound to help the valves seat.






New seals, a light lapping job and back together.

Look! I've got a Blast now!





Here's where I messed up. I was supposed to install the push rod tube first or you'll have a heck of a time getting this bolt in. I ended up cutting a cheapo allen to fit, no way was I going to take this apart just for that bolt.





That sure did eat alot of time up and I still have number 2 to do. Glad it's not a Goldwing!

Today I worked on cylinder #2, honed and in place.



Boy I screwed up on this one. They give you a little plastic tube to go over the valve stems grooved surface so the seal can glide on without damage. In my hurry, I put one of the seals on a valve without the sleeve in place. I didn't see any debris of the seal on the lands of the valve stem and I oiled it pretty well, so I actually think I'm ok. So it was time to put on the head and install the cams.



You have to line up all the little dots, "V's" and lines. It was time to call it quits for the day. Do yourself a favor and check the entire box for gaskets. I thought it was missing the oil pump/cam cover gasket and the primary gasket, so I went to the local dealer since it I was nearby. Today, I found the gaskets under a supporting cardboard. Sheesh!



Starting to look good though.

Looking really good! Keep posting this stuff, I'm sure one day I'll need it for reference!
