QuestionI found that my engine has a hole blasted in the side. Now I am looking for some information to find out what engines interchange directly. There are other 31G777 engines for sale for around $400 but I am not sure if they are a direct interchange. Is there an interchange application online or chart somewhere? Thank you.
Answerhi scott
1st you need to know hp rating, in this case its 17 .5 hp ohv
then wether its electric start or rewind , then its muffler position and engine to chassis mounting holes position and size , then pto shaft length and diameter
and is the pto take off a manual clutch or electric clutch
then may need to think about wiring connections from loom to engine ( most can be adapted or made to fit ) and the engine length, width, hieght if fitted in enclosed housing
(old engine size is 19.08 inchs long,-- 15.2 inches wide,-- 12.4 inches high)
if you have seen other engines around with same hp rating ,pto length , size and electric start
with oil filter and full pressure lubrication and engine mount bolt holes positions they should fit as long as specs as above match but if was a slightly higher hp rating ie (18.5 hp ) that would be a good thing
would pay to view engine 1st and compare dimensions etc before purchase
as far as interchange info chart have not seen one ?
but always pays to replace engine withcompatable engine as to what was removed and at least same size hp rating or better so you wont run into fittment / equipment issues
cheers hope it helps
