Got some brilliant news this morning my heads are done and gonna be shipped tomorrow, fingers crossed all will go smoothly.
In the meantime the rear main oil seals arrived from Shaun (thanks mate) so assembly was on this weekends agenda, I thought I would get the crank, pistons & rods in the block and degree the cam in but it was 130 degrees inside so rolled it outside, even outside the spanners were getting so hot you couldn't hold them !!!
First job was to gap all the rings which didn't take much time at all, then onto fitting the piston pins in the rods, The rods were setup for pressed pin or full floating, mine are full floating and a little tight so I popped to the machine shop and honed them out slightly to give .0008" clearance, the pins are located by 2 spirolocks either side, they are pesky little things to get in and even worse to get back out again !!!
Crank pulled a nice 40ftlbs on the torque wrench which is what i would expect.
Next job was to get the roller cam in and timing gears fitted so I could get the cam dialed in with a degree wheel, I'm using a hydraulic roller cam so had to make a cam button to keep the cam in the same place in the block, I gave it .060" clearance
For those that don't know a normal flat tappet cam is ground with a slight angle on the lobes which keeps the cam in the block and stops it walking forward, a roller cam is ground flat so needs a can button to keep it in place.
I'm using a Comp Cams Magnum true roller timing set, nicely made set.
I had already machined double keyways into the crank so all that was needed was to mod the oil slinger to slide over both of the keyways.
Virtually complete except for the heads which hopefully will get here sometime next week.
.Its aweful lonesome in the saddle since my horse died.
I saw last night on fb about John. The world sure lost a great one. I'm going to miss his humor, advice, and perspective from another portion of the world. Rest in Peace Johnboy.
