I have been seeing some posts about converting a Raptor to use a Zenoah gas engine.
Before I take a leap, can some one measure the start shaft bearing block width on a Xcell gasser.
I'm thinking of using a Xcell clutch/fan/spur gear assembly on the Zenoah.
A guy in Sweden has fit a zenoah into the bottom frames of a Raptor 60. He is using a old Kalt fan and clutch which are not available here.

Ps can you also measure the Xcell fan outside diameter?
thanks.

The start bearing block is 20 mm wide. This dimension is the same for any X-Cell that I've seen.

MIne is all assembled, so it's not so easy to get at the fan.

The lower frames have about 88 mm between them and the cooling shroud fits with a few mm clearance on either side.

thanks for the info.
Do you have a gasser Xcell?
I'm wondering what the spur gear tooth count is?

The pinion gear has 14 teeth.

The main gear has 90 teeth.
