G`day everyone. Not a bad days work, the PJ2 has been stripped down as far as I am going to go, no significant problems were found except for a lot of perished rubber/neoprene seals, these will all be replaced. There was a lot of detritus between the cylinder cooling vanes, largely mud wasps nests, mouse sh1t, leaves and dead spiders; degreaser, a wire brush and a pressure washer has got rid of the problem.
I hate working on British machinery of this vintage, late seventies thru early eighties. Britain was going through metrication so this thing has UNC, UNF and Metric nuts and bolts, two sets of spanners and 2 socket sets required. spent half the day trying to find the right tools for the job. A few nuts had to be removed with an adjustable spanner, not 1/2" nor 9/16" , 13mm too small and a 14mm spanner is too big, I`m thinking they may be old Whitworth sizes.
Another worrying issue is that most of the nuts and bolts were little more than finger tight, according to the hour meter this engine has done less than 100 hours from new and the service manual does stipulate checking for tightness at it`s first service at 250 hours. I guess that it has never had that first service and that a lot of the gaskets have shrunk over the last 40 years.
I`ll start ordering the bits needed tomorrow. I`m still looking for advice about replacing the plastic seals on the pushrod tubes.
A couple of pics attached.
