All the Cat 4 cyl. engines I ever saw were 1-3-4-2 so yours should be that too.
SJ,thanks for the info,one more question for you.What is the thread size of the spark plugs.I am trying to make a compession tester, i can't seem to find top center of #1.The marks on the pulley are gone. The tractor did run when i got it,but just barely,hard to start. Are the exhaust valves the front ones? Thanks Mike Durkin
Mike I,m not familiar with a 10 but I,m guessing it probably has 18 MM plugs in it but don,t know. You could take an old plug base and make up an adapter from the bottom part with the threads on it and I,m not familiar which valves are which either. I think you could tell by looking at the exhaust port outlet position from the outside and determine it from there. There used to be a Durkin from the Philly area come up here in the Wilkes Barre area and do construction work a few years ago and it seems they came into the Cat dealer when I worked there. I can,t remember if they did demolition work or just what they were doing here back then.It,s probably been 18 or 20 years ago before I retired that they were up here working.
Mike,
If you are looking for TDC on number 1 cylinder, you might be able to pull the plug and stick something long enough in the plug hole. Putting your finger over the plug hole to determine the compression stroke and getting close to TDC will allow you to use a shorter "finder". This is assuming the plug hole is directly above the piston and not offset over the valve area in this L head engine. be careful you don't stick something so short in the plug hole that it can be dropped which would require you pulling the head to retrieve.😮
Good luck,
Tom
I am restoring a 1930 CAT 10, the painter knocked off the spark plug wires. Assuming the cylinders are in order 1 through 4 from the front of the machine, can you tell me the arrangement on the magneto?

"I also joined a year ago. had been on here a couple of times as a non-member and found the info very helpful so I got a one year subscription (not very expensive at all) to try it out. I really like all the resources on here so I just got a three year. I think its a very small price for what you can get out of this site."
