Happy New Year Gents!
I found a few threads pertaining to this swap but didn't get any definite answers.
I have a 4016 with the Vanguard 16hp engine. It has over 1,100/hrs on it and it's starting to show it's age burning some oil on startup, using oil through the summer months, leaking a little from the main seals, and pulling some oil through the breather tube. I've pulled the engine a few times and I promised myself the next time would be repower time. Well, now I have a good excuse to pull the trigger. I put a new starter on it this summer and like an idiot, didn't think about it needing the nylon pinion gear. The starter bound up yesterday and I found a broken ring gear tooth.
I could put a new 16hp or 18hp in it but I figure the few extra bucks spent on the 23hp would be well worth it blowing snow. Based on the research I have done, here's what I understand (minus the little stuff like choke/throttle cables).
1) The 23hp with the black blower housing and cooling fan are deeper, which prevents the pump drive adapter from bolting on directly.
2) The 23hp with the red blower housing and cooling fan are shallower and will accommodate the pump drive adapter.
3) The 23hp is longer and may require drilling new engine mount holes in the frame.
4) The 23hp is longer and may require a different PTO clutch that locates the pulley inboard, closer to the crankcase.
Here's what I don't understand:
1) I have searched Small Engine Warehouse's site and cannot find a 23hp Vanguard with the shallow red blower housing. Are these discontinued?
2) If you use the shallow housing, do you still need to move the engine forward in the frame and use a different clutch?
3) Does the new clutch (if required) fit the 1" x 29/32" crank or will I need the engine with the 1-1/8" x 3" crank?
Any input is much appreciated! Thanks in advance!
