[QUOTE="Tazza, post: 2196, member: 82"] Nice, thats still no small job to have done! Well, the bushings aren't bushings as such, as you said they are bosses, with no replaceable bushings inside them. I have changed the ones i welded to te frame a bit as to hopefully prevent the pin from being able to move at all to make it so it will only wear on the correct part. I will replace the bosses on the lift arms and rams and machine them so i can make some press fit hardened bushings so when it wears i just knock it out and replace the bushing and pin. A time frame is hard to say, the engine took me a few months as i had to get the machining done at my dads work when they could fit it in. Then re-assembly didn't take all that long, but i went slowly as to get it all rite. So i would say a day or a day and a half on the engine, thats taking into account cleaning all the old parts before re-assembly. I got about 4 weeks off over x-mas and really got stuck into it. But again, you do a heap then you have to wait on other things. The new bosses i made for the chassis took me a day to make 8 of the rotten things. I chose the worst steel possible, i think it was induction hardened chrome bar. The outer skin is a hard as diamonds it was a nightmare but i did get through it. So, all up it really has taken a long time as i have made alot of small things for it that all take time like new ram sticks that need threading etc. New pistons for the rams and new gland nuts. I'm glad i'm not charging myself by the hour! but its a good little project it keeps me busy. I hope to have it all finished in the next few months, time allowing of course. [/QUOTE]
