No nothing like that - I'm a doctor and they are terribly short of doctors in the bush. I like to go where I can do the most good - so I go bush - where-ever I can do good.
Ahh; well bloody good on you, mate!
But onto more important matters.....
Progress with the Self Propelled - and more questions.
I have managed to get another stud out, meaning I have now got three out - so there is nothing stopping me (as far as I know) splitting the crank cases - so that is my next task.
I had given the cases a wollop with a rubber mallet, and I think I have broken the seal between the cases, I can see movement there when I move them by hand.
I can also see movement between the barrel and the crankcases, so that is fgreed up.
The piston, while it has moved a small amount, is still quite stuck in the bore.
So....
Where do I go from here? How do I get the crankcases apart? In the Victa manual I have it says whack one end of the crankshaft with a soft mallet - I've done that, but not a lot happened.
Am I being too gentle??
Always better to start gentle and ramp up as necessary, I feel. It's the bottom crankcase half that has to come off first here, as the remaining stud is in the top half. BTW, the points cam is a slip fit on the shaft, unless it too is rust-bound, so it needs to come off too.
First you need to get the blade disc boss off the shaft, and there's a bit of a trick to that. It's held on by matching tapers, i.e. male on the shaft and female in the boss.
Removal procedure is described in this past thread:
https://www.outdoorking-forum.com.au/forum/ubbthreads.php?ubb=showflat&Number=53044The crankshaft pulley is on a parallel shaft section, keyed with a woodruff key. It
may need a puller to get it off; if so the 'bearing puller' type is the best one to use here.
The workshop manual procedure is:
(1) Temporarily install the crankshaft nut.
(2) Place two suitable levers behind the pulley and while applying pressure to the pulley gently tap the nut to release the pulley from the crankshaft. Take care not to lose the spring from behind the pulley [where fitted].
Which Victa manual do you have? Of my collection, Gregory's #103 has good coverage of the pre-1972 SP, but #424 is better.
