Cam chain adjuster bolt 400-4

(1/3) > >>

Tiny Tim:
Right next stupid question.
At some point in its life my 400 has had the cam chain adjuster bolt located at the front of the engine replaced with a none standard part. I now have the right bolt, washer, o ring & nut to replace the crap one.
What I can't figure out is, can I just remove the offending item and fit the new one or is it more involved.

Cheers

Tim

mike the bike:
Just swap it over.  In doing so you'll tension the camchain,  providing nothing is seized.

Tiny Tim:
Cheers Mike.

Spot the difference

Clearly the bolt removed is bigger and not an original part.
Not sure what to do next.

Any suggestions?

Cheers
Tim

Looks to me like the engine casing has been drilled out and re-tapped. Those bolts tend to seize in place if not greased up and moved occasionally.

Looks like the PO has stripped the thread out and done a home made repair. You may need to get someone with a lathe to turn you a special bolt to fit, a copper washer under the locknut and a turn of ptfe on the threads by the locknut will probably stop any leaks.

Somebody on here will probably know a tested fix as its a common problem. Sounds like Mike may know as he mentions it being seized.

Pretty sure your new bolt isn't going in there any time soon though.
