100HP REMOVEL OF BOLTS PROBLEM (pictures)

[toey77]

i have a 71 100hp (x2) i am in the process of trying to swap out the tilt of the parts motor to my super clean motor but i am stuck on some bolts that I am guessing pressed in any ideas on how to remove these at home

Re: 100HP REMOVEL OF BOLTS PROBLEM (pictures)

I had a similar problem on my Yamaha motor ... caused by the 4 plastic bushings that are inserted in both sides of the shock absorbers, through which the bolts pass. Spraying some PB Blaster or similar solvent may help some, but brute force is all that's need to get the bolts out. If you can get a crescent wrench between the head of the bolt and the housing, you may be able to hammer them out by beating on the wrench.

As for the bottom pivot pin, there are two cotter pins that hold it in position ... both need to be removed before the pin can be removed. There are also 4 more plastic bushings for the bottom of the shock absorbers that may cause the pin to bind ... but at least you can drive that pin out.

Good luck!

Re: 100HP REMOVEL OF BOLTS PROBLEM (pictures)

PB blaster is a penatrating solvent you can buy at most parts houses and the "Blue Wrench" is a torch to provide heat for the area around the bolts and pins. An Acy torch is the best but you might get by with a Mapp gas set up.

well i got the bolts out with my map gas torch. i was just cautious at first cause i wasn't sure whether they were threaded or not... ohh and in Australia the "blue wrench" is a "gas axe" so thanks guys for your help

Are there cotter pins holding that long rod in place?

only on the inside part if the gas struts there was also plate that bolted to the underside the cotter pins were easy to remove
