1980 25hp johnson

[Shawnfish80]

Im doing a restoration/total rebuild on a j25rcsa (1980 25hp) and want to know if anyone can tell me torque specs?

 

[Shawnfish80]

Anyone know why every revolution theres a light clunk and hesitation when i turn the crankshaft?

Maybe a loose connecting rod ??

 

[werewolf]

if you had the rod caps off you may have them on wrong rod or backwards ,or a bad bearing

 

[boobie]

What did you ever find out ??

Well...i had not touched anything in the crankcase when this was happening. Completeley disassembled the powerhead,crank etc...and put the crankshaft,rods and pistons back in and when i turn the flywheel( its off im actually just turning the nut on the shaft but theres no clunk or hesitation now so im not sure what was causing it. I do have a question though...anyone know of any assembley info for reassembling a motor that has been taken 100% disassembled??

A factory service manual has it step by step.---But you knew that I think.

You will find the torque settings in appendix A3 of the manual on the Boatinfo website

Boatinfo - 1971-1989 Evinrude Service manual

www.boatinfo.no

You will find assembly instructions in the main part of the manual

You will also find how difficult it is to work from a manual that covers umpteen hp sizes spread over best part of two decades
