Hi,

Have a several year old Ariens Snowblower.

Can't seem to find a parts list for it.

Question: The bearing blocks on the side plates that hold the Auger shaft

Are the screws most likely Metric or English ?

Thanks,
Bob
If it is a REAL Ariens unit built in the USA most likely SAE threads.
If it is the low priced big-box store Ariens built in China, most
likely metric.
Of course, it could be American and metric - not likely Chinese and
SAE
