New Members Cafe / Old McDonald and me...
« Last post by Ol Banger on 24 May, 2019, 10:10:30 pm »
Hi everyone.
I'm new here and look forward to learning heaps more about Australian made engines of all makes.. but especially McDonalds.
I've been admiring these classic old engines for almost 30 years at various shows and rallies and finally I've found myself a McDonald SE.
I have the chance to buy it but as I'm new to this hobby I have no idea what a fair price is for it. As you can understand I don't want to offend him or rip myself off.
The engine runs and is in good original unrestored condition.
I'd appreciate any advice on this topic.

An admirable restauration ! Looks brand new.

I have P5M from 1937 plan an overhaul but do not have any experience with overhauling An old ST and have no connection to someone who has fone it before.

I would tremendously appreciate if you would be prepared to share your experience. Since i am slightly concerned that I will make all the beginnings mistakes.

Looking forward to hear from you.

Robert

It is also determined by if there is still a ridge at the top of the cylinder left by wear.Trying to push the piston over the ridge can have disastrous results.

Ausdok; The thickness of compression plates is usually determined by measuring the clearance between the piston and cylinder head at TDC. Known as the "Bumping Clearance" it is measured by placing a piece of led on the piston and measuring its thickness after the engine is turned over TDC. My instruction book for the HD9 engine make no reference to to this adjustment. Does your engine have any shims fitted. If not I suspect these engines may have been built to a tolerance that did not require adjustment by using shims.

Hi we are nearly finished the engine .what we need to know is what id the distance from the end of the conrod to the centre of the crankshaft. We need this to work out if we need to put in a compression  plate. Regards Rudy
