Primary Put Together

Alright, time to make some progress on the shovelhead.

The motor is in loosely with no primary between the motor and the transmission. The transmission is still bolted in tight.  To get everything lined up, I tightened all the transmission plate bolts and loosened all the nuts on the transmission studs.  This will let my transmission move while we work.

The next goal is to loose the front motor bolts and torque down the rear mount bolts. For whatever reason the Delkron cases and this frame don't really allow proper torquing of the rear nuts so you have to do something like this.

The next thing I did was check the gap under the front motor mounts to see if shims are needed. They haven't been required before with these cases in this frame, but there's no reason not to check. I couldn't get a 0.0015 feeler gage in the gap so I will say we are good to go.

We can actually torque these now.

Now tighten the head bolts to the top mount.  Again, I don't have the torque adapter I need to do this. So we just tightened them good and tight. Make sure the shims between the frame and mount fit up nice and tight.

This one is an easy torque.

This is where we had to back up. I forgot that my regulator mount goes under the front of the motor. We also looked for like a half hour trying to find my new regulator only to realize that I left it at Longbow Customs when we were working on it there.

We'll just put this on like this for now and I'll put the regulator on when I get it back.

Now on to the motor plate. It's my understanding with a stock inner primary with a chain, you bolt the loose transmission to the inner primary and bolted down engine. The belt setup is different, because you have to adjust tension of the belt before you bolt the plate down tight.

We just snugged everything for now.

The top belt guard goes on before the clutch shell. We had a heck of time getting it all to line up for some reason. Then the clutch shell and the 52 long bearings.

Retainer plate next.

Clutch plate stack up.

Tada! Pressure plates and springs. The pushrod screw is adjusted, but we'll need to adjust the nuts on the studs once we are actually ready to get this thing running again. Engine sprocket on and belt in place. Torque the four nuts and fifth stud of the transmission and we are done for the day.

A huge shout out to this guy. RevChong spent most of Saturday hanging out and helping. The moral support was the biggest part. I have really been uninspired to get this bike back together for way too long.
