Hello to all, its been a while. The short block has been sorted, now it's up to me to fit barrels, pistons, heads, dizzy etc.... right to the refit
What a bloody nightmare....1776cc B+P john mahle.
Out in the shed (Tuesday afernoon) fitting one side up, happy days. After lapping the barrels to the heads and sealing up to the crankcase, torquing down this is easy, so cracked on with opposite side cylinders 3 and 4 lapped and prepped so decided to go for it, just losing the light so locating the con rod pin retaining clips was a *******, but carried on regardless and got both sides finished, then it got to dark so retired to the house for a bit of shut eye.
Wednesday morning, looks pretty pleasing my efforts as shown below
However, soon the swear words where very loud and very, tried to turn the crank shaft, and got a tight spot in same position. Maybe i should not of worked into the darkness.
Got the problem down to one barrel after using the listening to the screwdriver trick, had to bite the bullet and stripdown the one side, however in doing so pulled a piston out of its barrel and with no piston ring compressor that was me finished for the day had to pop to a friends to get one.
(Thursday morning---today)After ringing the machinist and checking whether right bearings used and timing marks aligned, he suggested i looked at the clearance on the piston skirts as they come out of the barrel into the case. Sure enough, not enough clearance to take the piston into the case. So now using a drill and grinding bit i had to remove some metal upside down to prevent filings entering case. After about 2 hours of this case had be opened up enough to clear, so now it was a case of cleaning everything and refitting barrels, pistons, heads, torqueing etc....now all done and fitted dizzy drive shaft, and dizzy. Waiting for some rocker shaft shims to set valve clearances as these swivel feet require quite a bit of shimming under the rocker shaft themselves to set the 0.006" gap, hopefully tommorows work......Also waiting for a BMD pulley system to come into stock. So heres where i am now, not that much different from yesterday....
Roll on vanfest....... :]
