Ok just so you know Tom sifton made about 4 or 5 different ones for the shovel do you have the 3 didgit number on it like 102 - 103 kind of thing --

taiwan tedd is re making sifton cams and the gears on some are just installed with no idea about timing - china or india junk

 

yes I was figuring the Sifton cam was import for what it is worth it says made in USA. the cam looked like it had been in that box for quite a while. when I checked the lobe lift .310 with a dial indicator it was close with with 1.43 ratio came to .443 on intake lobe. The cam timing must be close it sure starts and sounds great.
I found a better instruction manual for the S&S oil pump the one I printed out a few years ago was out dated this new one has a much better diagram of the oil ports. Spent the last several hours trying to print it out.. stupid printer i don't use it enough I guess. Enough engine work for a while I am pleased and now have a direction to go with it. The new starter system works great and the used stator / rotor along with the new regulator is working. Clutch primary drive all good. all in all not a bad weekend.
welded a few more tabs for exhaust pipes and fuel tanks.

 

points are not made in the uSA anymore and they dont last worth a dam

put a dyna trigger is stupid simple and it works with no issues for a long time


its looking sweet BTW going to be a fun ride

 

one of these? I didn't want to install it until I got a little further along for fear of frying it and since it is used I dunno if it works. don't really like the looks of the coils can I use a stock coil?
red to +
black to ground
white to coil?



Thanks

 

The image of the pumps S&S {the one on the right} fits 65 to 69 and has an excess oil pressure valve relief port upper left on the pump just above the top mounting holes.
That's why the early alloy pump doesn't work on a 70 and new shovel.
The used pump I got doesn't have the relief port it also has a plug on the body right side as looking at the image, my stock 68 pump does not have this plug I don't know what the plug is for.
so from what I gather the pump on the left must be off a 1970 - 72 engine and does function on my Delkron cases.
From a service bulletin I found is says in 73 -81 the pump has a regulator valve in the pump which separates oil from the bottom and top end.
The reason is to supply a more constant pressure to the lifters and top end, {correct me it I am wrong}
This is why the oil pump I now have on the engine is working it just doesn't have the up graded regulator valve. It would have been nice to have had the later 73 up pump, this one will work for now until I can afford the correct one.
I don't think I needed to relieve the cam cover to have the larger feed hole feed the lower end since the cases were drilled from the pump feed to the timing cover case it was .125 it looked kind of small to me for feeding the bottom end but must be enough.

 

2 questions -

1 the oil pump and the set of cases you have, the very early delkron cases you have its been for ever since i have even seen a set, the volume of engine work i do causes me to take a step back and the reason - i looked for the old directions for those cases and did not even find any and i know we had them years back, i cant remember but i do know oiling issues were a thing and you Must talk to them and i would buy new what ever it is they tell you - you need - you could loose the motor if you dont, i cant give you a correct assesment of what to do as i have lost touch with the info that could help

second question - the dyna ignition you pictured is a single fire and the coil in the picture is duel fire BUT if you have 2 of them you can use both and single fire the bike

what you have could be mis matched parts for the most part, and you cant use it to duel fire Because the rotating trigger magnet only has one magnet and thats for single fire ignition - the duel fire ignition the trigger has two magnets - in this case you should buy a new complete duel fire trigger and stay ignition plate as that is a great coil, and i have never seen one go bad but the ignition i have replaced some not many but theirs always that chance its bad - jz

 

yes that is what the Tech guy @ Delkron said also these are early sand cast type cases.
I wouldn't know the difference since these are the "only" Delkron cases I've seen in person. I'm sure the guy who sold them to me said good reddens... I bought without doing any checking around. After I got an inspection plate and found it was to big for the hole is when I discovered I had an albatross kind of deal going on. Oh well I am always up for a challenge. I had the cases milled to fit the later DKM cases no big deal seems to be working fine down there.
I did a test this afternoon to see just how well it is getting oil to the crank pin, after some thought I decided to plug off the oil port to the heads so I wouldn't get any oil drain from the top end down to the cases. I then removed the spark plugs drain the residual oil from the cases for a few hours. screwed the drain plug backing and spun the engine over briefly, just until the oil pressure came up. and quickly removed the drain plug to find plenty of oil. I am guessing some oil would drain from the cam side from the lifters {or would IT?} but am pretty confident most if not all the oil was coming from the crank pin..
does this sound reasonable?
thanks for the info on the ignition the guy who sold me the oil pump gave me the ignition and coils he said they worked but from what I gathered he wasn't very knowledgeable of the system and I've never used any Dyna parts...yet does look like a good setup. I figured since I had the points for now they would be more fool proof. I don't want anything to complicate the first start up in a fresh engine especially this one with some unknowns with the oiling
from this image I am pretty sure the cases were 70 -72 oil pump configuration and someone drilled the pinion oil hole to the timing cover side as an update.
If the bike were a little more complete. I would be tempted to take it for a short ride testing on the lift is all looking good.
I did change the pressure relief spring the cold PSI was out of sight. the lighter spring from my 68 got the pressure down. will have to see how the hot psi will be. the solid lifers are next as loud as those pipes are I won't be able to here them anyway.
thanks again for your input.

 

those early pumps will put out over a 100PSI cold and almost zero when hot - put the other spring back in trust me on that

i have many of S&S oil pump directions and its very possable you are stressing a non starter as the system works -- drive it for 10 miles at normal speed always going in the direction of the shop so if it starts making crazy noizes its not far away - jz

 

ok I am convinced your right 100%
I will get an S&S 31-6203 pump coming when I can afford it.
there are sifton, revtec and another one but if I am going to spend the $$ S&S would be the best I'd guess Delkron also make one but a 100$ more than the S&S from what I could find.
I'll also have to purchase the 94461 jig to drill a hole in the case, 30$ for the jig but looks like a tricky angle to get correct.

the Sifton cam is a 109.
I have plenty to do other than the engine, got a little tunnel vision there for a bit.
thanks

 

The 109 is the old stroker cam works well - in 86 to 93 inches you are able to use hyd or solid liftrs .308 lobe lift 262 / 268 duration that is plenty BTW

oil pump i see extra holes in the blocks nose face already - question the pinion shaft is it end oiling or is it side oiling and what is the part number in the cam cover -- jz
