does anyone know if there is a typical shaft size on the 5 hp engine?mine bit the dust i need to order a engine.. thanks guys
3/4" is the most common (and the cheapest). Change the coupling half if necessary.
thanks saw guy i noticed in the nort. tool they also had diff lengths. if needed should they have the coup? is it a reducing type coup/ all new to me. thamks for the reply

I've also seen them in 5/8" and 1" diameter on occasion.

Quotemine bit the dust i need to order a engine.
Is it not possible to measure what is on the old engine?
o yea can do .that will be my safest bet ,for sure . seems like a few years ago the repairman tole me 1in. does that make it a bas#a*d size? didnt see that option in the n tool site,if so do they make some sorta adpter? thanks,, been there
That is the best way. It is likely 3/4" x 3 5/32" assuming it is a horizontal shaft engine, this is common and cheap for the equipment manufacturer. 1" is available but more expensive. If the dusted engine is this style, the new ohv will likely need to be shimmed to align the shafts. If a vertical shaft things get more involved, a standard mower engine won't work.

its a horizontal shaft.but can the 1"engine be replaced w/ a3/4 engine ? im not sure how the shaft marries up to the pump.
It likely has a lovejoy coupling, two metal drivers with a neoprene star between them. Change the engine side coupler if necessary and ensure the shafts are aligned. If they are not, the unit will vibrate and the coupling may fail.
Quotedidnt see that option in the n tool site,
Graduate to a different site, and maybe look at Surplus Center (surpluscenter.com). IMO much more helpful.
But it is your nickel. ;)
