I have a B&S 33S877-0013 engine in a Husqvarna CTH2138HR ride on. I am about to replace the cam in the engine and have a new sump gasket, oil seal, etc. I can't find the tightening sequence for the sump bolts. Does anyone have a diagram or point me to one?
What are the torque specs for tightening the the belt pulley bolt and engine mounting screws on the frame?

Appreciate your help.

Don't have that model of mower available here but these the normal torques used here. But do have the engine available.

Engine mounting screws 20 ft-lbs.
Engine PTO pulley 55 ft-lbs.
Engine Sump cover (closure plate) 220 in-lbs (three steps). Note: I had at least one engine that stripped one of these screw threads out at 210 in-lbs. That however appeared to an one off incident. Helicoil installed and no further problems.

Torque sequence

Thanks StarTech that is really helpful.

I can send you a PDF of the Service Manual for your engine if you like which will include information you need now and in future. Address below, put in proper format and remind me engine model number and what you want.

Is it advisable to use new bolts or use the existing ones? Engine has run ~130hrs.
