Pointy rear engine bolt - SV650.org

Stilo · 22-09-17, 10:45 AM

I cant get the rear lower engine bolt out of a K7 pointy, its stuck fast, its the last one to come out as recommended in the manuals. Lock washer is off & the nut is off on the right side but I cant shift it. Are there any clamp bolts or anything not mentioned in the manual, does it unscrew or should it just slide out? Ive soaked it in penetrating oil but it just wont budge. Any ideas?
Thanks

I don't know the bolt but have you tried tightening it a little first to try and crack the possible corrosion seal it may have made?

Yes I tried that, warmed it up, soaked it with penetrating oil but it is stuck fast.

Can you locate it on this parts-fiche?

Might help.

I think i have identified it but all it shows is a long bolt with a thread on the end. I dont know if it threads into the frame (unlikely) with a nut on the end as extra security or if it goes straight through the frame with just the nut on the threaded part of the bolt. Either way it is tight as tight can be. I guess that it is corrosion between metal bolt & ali engine casing or frame

You seem to have tried most things.I've used a homemade release fluid before using 50/50 Acetone and Brake fluid instead of ATF,

I also have one of these,

Which are fantastic for very directional heat application.

if its the last bolt to come out, you sure its not just all the engine weight keeping it stuck fast?

try man handling the engine abit while trying to drift it out, put the nut back on the threaded side a couple of turns and smack it with a hammer+bit of wood. (or a soft hammer if you have one)

Hi

I have tried moving the engine about & it is just the same what ever position it is I am convinced that the bolt is corroded in. I haven't tried drifting it yet as I am not sure if the bolt screws into the frame (I doubt it) or if it just slides through the frame, do you know either way?
Thanks

have you supported the weight of the engine using a jack?
