Oil Pump Spring

[1970 XLCH]

Thank you , Cotton . I have done that . Pulled the pipes & the rear exhaust valve had oil on it . I'm going to post another thread to see if I can find anyone that has had the same problem .

Did you happen to take any photos during your conversion?
There is also two different length pressure relief valves, but I cannot remember which is which.

Sorry no pictures , because this S&S pump was going to be the " solution to all my problems " UGH !!!!
The S&S pump runs Harley's long valve # 26400-82 .
The stock pump has the short one # 26400-54
Been trying to get some help from S&S . Talked to Chris a couple of weeks ago , NO HELP !!
Tried their email tech help , They responded once with a few questions ( nothing helpful ) , I answered them , but no response .
I'm probably going back to the stock pump & run solids . Thank you for your help !!

Sorry it didn't work out. If you pull the cam cover again, can you get some photos?
Cheers

More pictures they only let you post five per . Have a total of 11 .

[1970 XLCH]

Last one . See anything I messed up ??

[aumick10]

Looking over it now. Get back to you

[aumick10]

Which cam cover are you using?

[aumick10]

1970 XLCH,
I cannot see anything wrong with what you have done.
I assume you fitted the plug into the original crank feed port. Step 5.
The timing marks do not line up in photo 07, did you rotate the motor before you took the photo.
Check the cam cover gasket to the cover AND the cases.
There is no reason i can see why this procedure would have caused the rear cylinder to blow smoke. The only thing I can think of is the valve stem seal has moved. A big coincidence if it is what happened.

[aumick10]

The more i think about it, I wonder if the valve stem seal has been loose for a while. With the original oil system, the top end was getting a lot less oil, and this was hiding the seal issue. Now that the top end is getting the correct amount of oil, the seal issue is showing up.
I now it is a pain in the butt, but i would suggest you pull the rear head and check it. You have a lot of time invested now, and it will be a more pleasant ride when you eventuallu sort it out.

[1970 XLCH]

S&S has an inverted " T " as their timing mark which doesn't show up in pic 07 . I'm pretty sure I have it right . I am thinking of yanking the head , UGH !!

[aumick10]

I can see the pinion gear and cam marks don't line up. Cannot see the breather mark.
Pull both heads while you are at it.

[1970 XLCH]

Two marks on the pinion , a little hard to see . I believe it is lined up per manual

[aumick10]

You are correct. That pinion was also used on generator models.
