I have a 97 xr250 honda and the bolt going through the motor and swing arm wont come out is it tread in or do i just wack it out thanks
Hello!
I have had similar problems to you in the past and believe me just trying to wack it out can open one Hell of a Hornets Nest.(Bent shafts ruined threads)
More so the grief I've had has been on British Machines however your symptoms seem identical, Corrosion possibly or crud 'n' **** build up and although we think the good old Jet wash cleans somtimes in the Swing Arm area it can be Fatal, it pushes the sand and crud deaper into the seals.
I don't know how quickly you need remove the Swinging Arm but suggest trying a quality penetrating oil and after a good soak may be a little heat from a blow torch. Bear in mind Flame and Oil make Fire so keep a hose pipe or fire extinguisher handy. If it is threaded? Try turning opposite direction after soaking all gaps with oil it may be left hand thread? also see if there are any Grub Screws hiding underneath, finally If there are Grease Nipples give it a good grease before removing them and gently warming up the bearing areas. Good Luck!
You are doing this hopefully to replace worn bearings?

Hi Jeff,
O.k. so the bolt goes through the back of the engine possibly the top of the crankcases above the gearbox? can you get easy access to the area along the engine casing? if so possibly a gap at either end where a steel hack saw blade may gleen some Twizzling?? I know you may not be able to get a Whole hacksaw in to cut through the bolt at either end but there are some Air tools that use broken saw blades that could get into the tricky area allowing you to cut through and remove your engine so heat can be applied externally, carefully, sensibly and cautiously to remove the bolt. Alternativley?
We all know corrosion! ferrous oxide and Non ferrous metal (Aluminium) seriously do not mix so you'll have to look to other ways to accessing the top end.
Maybe a hotter direct source of heat such as OxyAcettyllyne from someone locally? I'm sure the right safe amount will help you to extract that Demon Bolt.
Please remember! if you do remove the engine with the bolt siezed in place from the sawing route serious bashing could wreck the cases I.E. fracturing/shearing the mounting from the cases, So possible drilling out the offending monster will be the only Winner?
I really admire you're effort's and please keep me updated, I hope this further solution helps you to FixYa Cycle!
