That doesn’t look like an 1128 gasket at all. Not sure WTF that is.
The 044 and 046 gaskets are different. That looks like a totally different model completely, as it tapers towards the front of the saw.
The easy way to tell an 044 from an 046 gasket kit: 1) The kit size is larger for the 046 kit 2)The 044 kit has the larger holed PTO seal because of the spacer the 044 uses. Both use the 1128 prefix.
