Howard Bantam - AC120 oil stick

[ChrisE 0]

Hi All,

 

This is my first post on this forum. I hope you can help me!

 

I recently purchased a AC120 powered Bantam. It was in a bit of a sad state with rust, but not bad considering it has been exposed to the elements for so long.

 

I am keen to turn over the engine, but my oil dipstick is missing, hence I can't be sure of the correct oil level.  Can anybody give me a few measurements of the stick so I can make a replacement?

Hi All. Thank you for the welcoming.

Still no luck with the oil stick. I am also not too sure about oil grade as well. I plan to replace the oil sump gasket as it is leaking. I'll make some height measurements of the oil slinger and try and fashion a crude oil stick out of some brass rod.

Before:

Partial rust removal and cleaning:

First coat of paint after sanding and degreasing:

I need to strip and paint the engine. I am still deciding if I should go for an LPG convertion; the carb is troublesome.

Saw this post after trawling the net for other info

 

 

measurements are:-

 

118mm from the washer shoulder to the end part (sump0 dipstick

 

The rod diameter is three sixteenths

 

the rod is cut to form a half moon in profile at dipping end to a total length of 20mm

 

there is a line  halfway at 10mm   ... this i take to be the median oil level..

 

this   bantum is new to me as well and i am not familiar with the measurement yet either

Thanks Vig!

 

I will use you measurements this weekend. I polished the valves and corrected the clearance. The intake valve was not opening completely. It has so much more power now. 

 

Now I have a new problem; the key sheared in the keyway and cracked the flywheel. I am guessing it is cast iron? How can I repair this? The keyway is damaged as well. 

 

Regards,

Ok. I did the spark test, it looks like the flywheel is cast aluminium with a steel ring to hold the key. The engine runs beautifully between the flywheel loosing itself; I was able to give my veggie patch a final pass before I start on seeding and planting.

 

The keyway on the crank is looking a little bit buggered. I guess the likelihood of finding a spare flywheel and crank is next to none.

 

I may have to replace the entire engine. Maybe I can make a simple  air compressor out of the old AC120?

 

Does anybpdy know the bearing sizes for the wheel axle? I have a bit of play in the RHS. I don't want to damage the gearbox.

 

Cheers,

 

Chris
