My plan for this weekend

Postby TiberiusCub » Thu Oct 05, 2017 10:52 am

Well, it might start tonight if the marvel mystery oil comes in (then I will remove the spark plugs and put a little down each spark plug hole).

Anyways, Saturday I plan on installing the battery cable ends (currently just has bare wires), removing the ignition switch and swapping it with the one from the 55 that actually goes on and off (I will take pictures of the wiring so I can get it back together). R&R the oil and filter. Add gas (and put in some MMO). Check the coolant. R and clean the air filter and the sediment bowl. R&R the points. Check the spark plugs and wires. Install the new battery. Attempt to start the 52!

Questions I have:
1. For the points, I understand they need to be set at .23, can I do that with a spark plug gap tool or do I need a different guage?
2. When I R and R the oil filter and oil, will that prime the pump?
3. I know there are other things I should do, but what issues do the "old timers" see with my list above?

I am hoping the 52 will fire up. It will make my weekend for sure. Thanks for everyone's help.

The points are actually .023" not .23". You can use whatever you have that is .023" thick.
The oil change will not prime the pump. There is a hole inside (about 1/4" diameter) where the oil filter goes, squirt some in that hole before installing new filter.

Battery cable ends, fresh battery.

Prime the oil pump. Check to see that there is sufficient oil in the crankcase.

Then compression tests, dry then wet.

Compression tests satisfactory - - then progress on to starting the engine.

I wouldn't spend any more money on the engine than I needed, to find out it's apparent condition.
I have an excuse. CRS.

This is the hole to prime the pump.

Hi,
The point gap is .020" for a Battery Ignition unit, and .013" for a magneto.
The points should be clean and shiny metal, file them or replace them if they are burned. It helps the engine start and run better.
You would need to buy feeler gauges for whichever thickness you need.

.023" is the gap for the spark plugs. They need to be clean and not oily at the bottom end to work good.
The contacts in the distributor cap should be clean and not burned, and the rotor should not be burned. Clean them or replace them if corroded.
The engine should be timed with a timing light if it has a Battery Ignition unit.

To prime the oil pump, fill a clean pump type oil can with motor oil, and squirt it into the hole in the pic above until the passage in the engine is full. It might take more than one filling of the oil can to fill the passage. :)

Thank you all.

Glen, yes I have a BIU, so the point gap will be .020. I will buy some feeler gauges. I went ahead and bought new points. I don't know the last time it was fired up and they were cheap enough to just replace.

It sounds like I will be buying an oil can as well :)

RG, thanks for the pic. That is helpful.

Eugene, I don't currently have a way to do a compression test and that is not something I have done before. It may be on the burner for later.

Thanks again,
TC

You can also use that oil squirt can to oil the fan hub.

Hi,
Here is a page from the 1955 Cub owner's manual showing the points. Good to put in new points.

I think NAPA sells compression testers, it is a gauge with a flexible hose. If you buy one, be sure it has a fitting that will screw into the Cub's size of spark plug holes. They are bigger than cars use. :)

Well, it's your money that you could be wasting on something that needs an engine rebuild or is not rebuildable.

Some auto parts stores loan tools. Some compression testers have adapters for different sized spark plug holes.

Eugene,
Thanks. I agree, I don’t want to spend more than I need to. On a related note, I took the ignition switch off the 52 and it crumpled apart. I then removed the one from the 55 to install on the 52 and realized I had no way to tell which prong to put the wires on. Any ideas on how to tell which boring to put the wires on? I assume it matters, but maybe it doesn’t with the push/pull switch.

Thanks,
TC

Is that a picture of the top of the oil filter housing? I just removed my oil and replaced the filter. I assume I just put oil into the top where the filter goes in order to prime the pump. Is that correct?

Thanks,
TC

Fill up the hole in the side that is about 1/4 inch in diameter near the top, on the block side of the filter housing.

Here is what mine looks like. I don’t see a hole. Sorry for all the confusion.

You have to remove the filter cover and filter to access the hole.
