Crashtd420 Posted January 25, 2018 Report Share Posted January 25, 2018 And studying your pics.... it looks like both marks are pointing in between the links... so as long as you have 44 links between them it looks good... Quote Link to comment
Crashtd420 Posted January 25, 2018 Report Share Posted January 25, 2018 I'm still trying to figure out you real issue... If crank and cam are at the correct orientation and the right number of link you should be good.... Are you sure it's the chain binding? Maybe its just the extra tension of the valves springs....

datzenmike Posted January 25, 2018 Report Share Posted January 25, 2018 Set the engine to this position with the marked link on the #2 hole. Take the chain off if you have to and turn or adjust crank so the other marked link is on the crank tooth with that dot. There should be 44 links between the two marked chain links and both should be on the distributor side of the engine.. The cam and crank are now correctly aligned.. In this picture below, the guide to the right of that marked link needs the bolts loosened and shove it as far to the left as you can and tightened. You can see there is still room left on that slot the bolt is in. Hold the tensioner in as far to the right as you can to make the job easier. You want as much of the slack removed as possible.

banzai510(hainz) Posted January 25, 2018 Report Share Posted January 25, 2018 look at my L series vid on YOutube or Vemio.com Just put in Hainz or Hainz Datsun Lseries its all in there to look at, just listen carefully if you put the brite links of chain on the dots on the corresponding cam gear it pretty EZ. (block)bottom at TDC is near 330 position) Head cam gear is near 2 Oclock position. when you put the brite link to the dimple marks on sprockets. you might have to rotate the came fwd or backward to get it lined up and on the sprocket. one on tighen everything up Slightly and put the front cover on with timming pointer and turn clockwise to TDC and then looat the cam timming marks if V mark and dash line up your good. the post #28 photo by Datzenmike shows his is off as the brite link and diple done line up and shows the V and dash not correct also(off a link) some new Taiwan made chains don't have brite links so one need to put chain on tight and then put from cover on to ck the timming dont forget to tmme the dist Quote Link to comment
Stoffregen Motorsports Posted January 25, 2018 Report Share Posted January 25, 2018 If you're confused, forget the bright links. Bring the motor to TDC, Without the chain on the upper sprocket, put the sprocket onto the cam and move it until the notch lines up with the dot in the cam plate. Try installing the chain. Is it close? It may be slightly off to one side or the other, but not by much. After you get the cam timing set, are you ok with installing the oil pump? Line up the dots and put it in as straight as possible to keep the dots lined up. Oh yeah, like Hainz said, don't forget to set your distributor timming after you're done. 1 Quote Link to comment

The chain was bound up at the bottom because I did not use a wedge. It is not currently binding I just want to make sure and time it right Quote Link to comment
Trod8812 Posted January 25, 2018 Author Report Share Posted January 25, 2018 If I turn the crank while the chain is not connected will he piston hit the valves Quote Link to comment
datzenmike Posted January 25, 2018 Report Share Posted January 25, 2018 Not if the V notch in the back of the cam sprocket is under the small horizontal line just above it on the cam thrust plate. Quote Link to comment
Trod8812 Posted January 26, 2018 Author Report Share Posted January 26, 2018 When I turn the motor by hand everything looks like it opens and closes when it is supposed to. I could leave the number 1 cylinder at TDC and move the chain around so the timing marks mate up. I’m not sure how important that is. I also never took the chain off of the crank sprocket only the cam sprocket Quote Link to comment
datzenmike Posted January 26, 2018 Report Share Posted January 26, 2018 Take the chain off and get both dark marked links on the distributor side. Should be 44 links between them. See the DOT on the tooth??? Turn the crank to TDC or about 4 o'clock as viewed from the front. Put the dark marked link on that DOT. Now position the cam #2 DOT at about 2 o'clock and get the other Dark marked link on it. This one is close... looks like one tooth off. On an L20B there should be 44 links between the DOTS. Also get that chain guide moved over as far to the right as you can like the picture above. Loosen the two bolts and hold the tensioner in while pushing the guide over as far as it will go, then tighten in place. Quote Link to comment
Trod8812 Posted January 26, 2018 Author Report Share Posted January 26, 2018 I will do that when I get home tonight then post pictures. 1 Quote Link to comment
Trod8812 Posted January 26, 2018 Author Report Share Posted January 26, 2018 If I move the cam link over one to the left it’s a little further away from the divot on the crank sprocket 1 Quote Link to comment
Crashtd420 Posted January 26, 2018 Report Share Posted January 26, 2018 If I move the cam link over one to the left it’s a little further away from the divot on the crank sprocket That looks off to me.... both the dot on the crank and cam sprocket should be pointing directly at the center of the link. .. It looks like the crank is before the link and the cam is pointing to after the link.... 1 Quote Link to comment
Trod8812 Posted January 26, 2018 Author Report Share Posted January 26, 2018 So I should just rotate the cam a little to the right? Quote Link to comment
Crashtd420 Posted January 26, 2018 Report Share Posted January 26, 2018 Also the right side of the chain is I believe the tension side... the chain looks like it has slack in the crank pic... Quote Link to comment
Trod8812 Posted January 26, 2018 Author Report Share Posted January 26, 2018 I have the tensioner is not on neither are the guides Quote Link to comment
Crashtd420 Posted January 26, 2018 Report Share Posted January 26, 2018 There should be a v notch that lines up that cam sprocket... Maybe count the links to be sure... Quote Link to comment
Trod8812 Posted January 26, 2018 Author Report Share Posted January 26, 2018 They look pretty close to 10 and 2 Quote Link to comment
Crashtd420 Posted January 26, 2018 Report Share Posted January 26, 2018 I have the tensioner is not on neither are the guidesStill when the motor runs as you rotate the motor by the crank it tensions the chain.... the spring tensioner on the left keeps the slack side from flopping around.. guides keep it aligned.... And those notches in that pic should be lined up... Quote Link to comment
Trod8812 Posted January 26, 2018 Author Report Share Posted January 26, 2018 i have not turned the motor since I took it off Quote Link to comment
Trod8812 Posted January 26, 2018 Author Report Share Posted January 26, 2018 Since it does not line up does that mean I have to turn the cam? Quote Link to comment
Crashtd420 Posted January 26, 2018 Report Share Posted January 26, 2018 Ya you wanna move the cam and get those lined up.... You can even go alittle past to get the chain onto the correct links... then when you back it up it will tension the chain on the right side.... Then verify both tdc mark and you have the correct link spacing.... Almost there.... Quote Link to comment
