I picked up an Ariens 11.5 28. The body is in excellent condition but the motor threw a rod and cracked the bore. I’ve been waiting two seasons to come across a replacement engine but no luck.
An engine has come up that might be a replacement, 13 hp Tecumseh OH358SA SnowKing 913300B. It should mount up ok but the chute support is a possible problem.
The snowblower model is 924121 which came with a Tecumseh OHSK110-221 221735D.
The issue is the bracket that supports the chute gear seems to be unique to this model. The models in this group are 924122 1124, 924332 1124, 924508 1128, 924505 1332, 924506 1336, 924118 8524, 924551 8524. Only the 924121 uses a particular bracket. The 118, 122, 332, 508, 551 are listed as using the same bracket. This is fishy as 118 and 551 use L head engines and the 122, 332 and 508 use OHV engines. I don’t think they can use the same bracket so a possible drawing callout mistake.
The 13hp’s in the group come with electric chute controls with chute mounts that clamp to the base of the chute so no engine bracket and no bracket parts that could be used.
The engine that came with the 924121 is a 318 OHV block. The possible 13 replacement is an OH358SA. The question is if there are any similar models around 2004 that mounted 13’s with a head bracket that could be used? In 2005 the chute support changed. The 924515 is a 13hp without electric chute control and used the back of the chute standoff. That might be a possibility but the gear housing components are different and probably too expensive to buy all those parts and scrap the existing parts. Given the bloc difference in 318 to 358 is there any head mount bracket that could used with the 358?
