Hello All,

The YouTube user has made another clip with some useful information about filters, etc.

Hello All,
To correct  a statement in my last post, the flywheel on the engine I received from Surplus Center appears *not* to be SAE standard as I thought. The tapped bolt holes are metric, and the other dimensions also appear to be metric as well. I will ask Hayes whether or not they can provide a stub shaft to fit the flywheel, but the price will undoubtedly be higher than for a standard off-the-shelf product. Have any other members fit a stub shaft to this engine? I would prefer not to bolt a pulley directly to the flywheel, if possible.
Cheers!

Hello Terry,

Mike Montieth made the eight groove serpentine pulley I plan to use for my genset. It is bored to fit an SK size tapered bushing so it can be used on different diameter shafts just by installing a bushing with ID to match the shaft. Mike did an excellent job - highly recommended!

Regarding the alternator drive setup, the stub shaft I want to use is an SAE 7 1/2 that bolts to the engine flywheel.

It will drive a separate auxiliary shaft supported between pillow blocks, using a Lovejoy type resilient coupling that transmits only torque, no side load, between the shafts. The auxiliary shaft will carry the serpentine pulley that drives the alternators. This is similar to flywheel's setup, except he devised his own coupling method instead of using off-the-shelf components. I favor using the auxiliary shaft to carry the side load, as opposed to attaching the pulley directly to the flywheel, although the directly attached pulley would probably be OK as long as it is positioned close to the flywheel. Perhaps others who use this type of setup would like to comment.

Hello from a newbie!
I am starting a DC genset project using one of these engines, and am interested to see your (and others') choice of radiator, air cleaner and other operating components not supplied with the engine. I am considering using a new replacement radiator for a small car like a Suzuki Swift or similar vehicle, as these are available through eBay and other sources for a reasonable price. Other components are still to be determined, although I will probably use a Hayes stub shaft and Lovejoy type resilient coupling to drive a separate shaft supported by pillow block bearings (similar to flywheel's Perkins genset configuration). A pulley on the shaft will drive automotive alternators (great work, mobile_bob!) through a serpentine belt. The larger plan is to make the genset one component of a generalized system to charge and maintain battery banks using multiple power sources.  If there is interest in the group, I can start a separate topic for the project.
Cheers!
