Hello I know mini trucks is not the focus or even one of the subjects of this forum BUT on the mini truck forum they do not do many engine swaps, there is a couple threads where someone has put in a motor cycle engine but has lost 4WD. This forum it appears dropping a different motor in something is pretty common, specifically a snowmobile motor.
The truck is a Subaru Sambar 660 with 4WD which I want to retain. The engine is toast and the options to rebuild or replace with new are too expensive, I would just junk the truck and buy another better one. With that I think it would be possible to power it with a Yami Genesis motor like the RX1 or the 998 3 cyl unit. Id even go with the 2 cyl as it generates 80hp. Id prefer the RX1 or 998 as used sleds with them are readily available and Id get all needed components and wiring.
My thought (if I can describe it in words and no drawing) is to create a plate that would attach to the tranny with a bracket on the outside of it to mount 2 or three pillow blocks to secure a clutch shaft to. On the side of the plate connecting to the transmission would be the stock Subaru clutch. On the outside I would attach at the end of the shaft the Yami secondary driven clutch. Then there would be a bracket extending out to the motor mount to maintain the distance between Primary and secondary clutches.
The one custom part would be the shaft that the secondary clutch would connect to and connects into the tranny's male connection point. It would require a threaded hole to hold the clutch and on the other end splines to fit into the transmission. I think I can do all of the other modifications other than the shaft.
My concern would be the pressure/force pulling on that custom shaft due to the tension and pull on the belt when the clutches active.
The reason I want to use the variable clutching is the purpose of the truck is to pull a snowmobile grooming drag and having variable drive is a true benefit. Shifting while towing a HEAVY load at slow speeds is tough to try and shift to needed gear without it completely stopping the truck.
Does this sound plausible? Any thought on how much the custom drive shaft would cost?
Thank You for your time, Phil
