EC15B exhaust mounting bolt to flywheel housing

[gardenshed]

Morning folks,

The exhaust mount that bolts to the flywheel housing has snapped on my EC15B. It looks like somebody has bodged it in the past as the bracket has been welded to the flywheel housing. When unscrewing the bolt that attaches the exhaust mounting bracket to the flywheel housing. The bolt was stiff to unscrew until there was a small muffled thunk from within the flywheel housing and then the bolt could be screwed out by hand. See pictures for the bolt I'm talking about.

My question is, what is inside the flywheel housing that this bolt screws into that I need to worry about?


Thanks,
Matt.

Hi,

I have a -15B but have never opened that bolt.

If you suspect that bolt is too long, take it out, measure the hole with a caliper to see if it hits the flywheel. If it hits the fw, install some washers to make it shorter.

stay safe

They were a b?@+ard for unscrewing and rattling loose so somone may have stripped the bolt and welded on something temporarily

Update: I fixed this over the summer. I bought an exhaust bracket £3.50 and a bolt 35p from VolvoCE.
I ground the bodge welding off and bolted on the new bracket with thread lock on the bolt. It's done ~50 hours and still holding fast.

I think the bodgers probably spent more time and effort and cost in welding and bodging the broken bracket on, than spending less than a fiver and doing it properly. Bit sad really.

Originality is good in my book so well done ... just ... nearly all of them rattle loose at some point its just a shitty design, having 18" of pipe bolted to a vibrating engine with an M6 bolt
