Variomatic Posted March 7, 2016 Share Posted March 7, 2016 I've spend the last 3 hours trying to get the engine out of the bike, every single fucking bolt holding the bike in is totally stuck in the bike, WD40, physical violence, high heat and a lot of time didn't get them out. As far as I can tell this engine is stuck solid in the frame. Any tips? Link to comment Share on other sites More sharing options...
blackhat250 Posted March 7, 2016 Share Posted March 7, 2016 How come you say head removal ,,if its the engine , are you shure you"ve got ALL the bolts, Link to comment Share on other sites More sharing options...
Malleus Posted March 7, 2016 Share Posted March 7, 2016 I assume you are using a decent enough wrench where possible, and you have mentioned using heat/oil. Not sure what else to suggest. I did have a very hard time getting bolts off of my YBR. In the end i had to drill them out and replace, which is obviously not ideal Link to comment Share on other sites More sharing options...

And yes I'm awake of bolt locations, I'm not a retard. The problem is that none of them will come out. And yeah Malleus, decent set of wrenches/sockets, lot's of penetrating oil and heat. The ideal solution seems to be to just leave the engine in the frame and do it within the confines of the bike. Looks like I'll be sitting in the cold for a long while. 1 Link to comment Share on other sites More sharing options...
blackhat250 Posted March 8, 2016 Share Posted March 8, 2016 Ah " got yeh , the engines out, you should have slackened them when engine in frame, ,, just like if your doing a water pump, [ car] losen pully bolt Before removing the belt, ,, Link to comment Share on other sites More sharing options...

The engine is in the frame but the engine mount bolts won't come out. Link to comment Share on other sites More sharing options...
blackhat250 Posted March 8, 2016 Share Posted March 8, 2016 Ah, nuts off, but bolts seized in frame/engine ,,. now that is a bitch, , the best penetrating oil . is, ATF/ACITONE, . mixed, but I think your gonna have to drift them out, . I would buy a spare set , as there gonna get chewed, .,leave the nuts on a few threads . see if they shift, .then spray in fluid at other end, tap back and forth , slowly,you"l need a steel bar [ punch] slightly smaller, 1 Link to comment Share on other sites More sharing options...

Every other bolt on the bike is fine, but these motherfucking mounting bolts, Jesus Christ I need a new bike. Link to comment Share on other sites More sharing options...
slice Posted March 9, 2016 Share Posted March 9, 2016 That's the way, on my FJ the engine bolts were welded to the engine and the frame with corrosion, the only way is to heat them till they glow and wind the fuckers off as best you can. I did try heat and cold shock on them, didn't seem to make much of a difference really, I ended up chopping the ends off and drilling them in stages till I got them loose enough to move. The only time I was really careful was when I drilled the engine casing parts as they can break off if your to rough. Good luck and have at it. 1 Link to comment Share on other sites More sharing options...
neversaydie Posted March 9, 2016 Share Posted March 9, 2016 Ive spent days in the past removing siezed bolts. I know youre stuck for time, but ive always found Plusgas the best release agent, soaked the bolts over a few days, tried turning them both clockwise and anti a touch at a time, heat then soak again. If you do get them to start to move, turn them back an forth and oil them as you undo 2 Link to comment Share on other sites More sharing options...
Variomatic Posted March 11, 2016 Author Share Posted March 11, 2016 UPDATE After probably damaging my torque wrench (beam type so likely ok) by using it as a 1.5ft breaker bar I managed to get every single engine mount bolt undone. Hoever, right at the bottom in the rear there is one bolt, one fucking bolt, the nut has come undone, but the bolt is stuck in the engine, and through the frame, so, now the engine is hanging from the frame by one bolts that's rusted in. Also it's so rusted in, after putting about 100ft-LB of torque though it it's still stuck solid, and rounded. Thankfully it's not threaded into the engine so it's a case of hitting it hard enough on the other end. I'm so close, and at the same time I want to burn this metal bastard to the ground. Thanks for so much help guys. Without this forum my bike would have been scrap long ago. If I ever buy a new bike, every single nut and bolt is gonna have a coat of silicone before it sees the road. 1 Link to comment Share on other sites More sharing options...
slice Posted March 11, 2016 Share Posted March 11, 2016 That's good news mate but just be careful when you whang the shit out of this bolt that the engine casing don't crack, if it's really welded in there your going to have to be patient. As above try plusgas and anything else you an think of to penetrate into the corrosion, heat it up but be aware that the casing can actually melt if you hold the torch on to long, I bet the problem is inside the casing and not the frame mounts, worst case you could cut the frame mounts off and then weld them back on after you get it free, bit extreme but might be your only shot if all else fails, if your not that good at welding your local engineers will do it for you for a few quid. Remember the bigger the hammer the more you need to repair afterwards. Keep going your so close mate. 1 Link to comment Share on other sites More sharing options...
jimmy Posted March 11, 2016 Share Posted March 11, 2016 As Slice states, you may damage the engine casing. If you can cut through the bolt at the inboard side of the frame lugs that will allow you to get the engine in a better position to remove whats left of the bolt Look up Galvanic Corrosion on t'web to get a better idea of what happened 1 Link to comment Share on other sites More sharing options...

Just make sure you dont peen over the end otherwise its spark erosion 1 Link to comment Share on other sites More sharing options...

In other words, the head is off, as is the piston and cylinder, but the engines in the bike still. So the problem is solved, all I've got to do is hope I can get the thing back together again 2 Link to comment Share on other sites More sharing options...
