This is a SC21 motor fitted to a SC24 chassis so the head needed to be swopped to get the water plumbing correct. The 21 has water ports behind the head, I needed them on the side to match the 24 water system. Pickup swopped to single coil to suit the wiring and head swop to get the water right. Should work a treat if the cams are in the right place. Cam caps are all in right places, just the actual cam in the wrong place. Cam sprockets are identical by the way. Intake and exhaust cams have identical sprockets which were both removed from the cams at installation because it makes the job "easier" apparently ?!

 

Now that sounds like an excellent opportunity for Mr ****-Up to pay a visit.

 

Well the exhaust camshaft part number should be 14201-MM5-010

And I can see a MM5 on that shaft.

I'm starting to think that for some reason, the cam sprockets were removed. When they were replaced they were put on the wrong shafts.

Hence the mix up.

I'll stick to that theory until alternative evidence arises

Cheers, SB

 

Sprockets are identical, they can however be 180 out on the cam

 

Yes, you are right, part number 14321-MS2-610

Shafts are in wrong place then, as you say. And probably 180 out!

Cheers, SB

 

OK, this is getting a whole like lot the lone sniper on the grassy knoll.

I'm not familiar enough with the internal workings but:

If you take the cam sprockets off, is there anything that would prevent you from reinstalling on the wrong cam ie: different pitch diameter, 3 bolts vs 4 etc ?

No TK - part numbers are identical for front and rear sprocket. Both have 2 bolts - again same part numbers.

So, quite easily they could have been swapped. But that now is a moot point.

However, from the photo that David put up, you can see EX cast into the camshaft - indicating it is the exhaust camshaft, but it is in the inlet position.

See, clear as Billy Crystal

Exactly my friend, the exhibit photo 4 clearly shows the marking on the sprocket showing IN (again if taken from the left) but the later photo shows EX cast into apparently the same cam.

I detect the whole whiff of an Arthur Allen Thomas cover up here, but we will see what eventuates before being all uppity and knowing.

 

There are "IN" and "EX" markings on the sprockets since the sprockets are identical and used on either cam. Remember the identical sprocket is used on either cam so each sprocket is marked with both markings

 

But do the cams have identical markings?
