Man am I pissed.Yea the pump itself is o.k but the thread in the main shaft is stripped and its impossible to pull the pully over it.I borrowed a tool but the bolt was a bodgy "mild" steel and broke off in there[Farrk].Well after much,much hassle I got it out.The thread is stuffed right from the start, I think. Being hardened it is impossible to clean up.So now monday I'll be after a new one.the original was broken mysteriosly when I machined the heads to increase compression to 58 cc chambers.I would say it fell off the table or something,but when you were a kid would you own up?May even need get another pulley as well, at $82. a shot.Oh well back to Thomson Ford...Again!! So much for a ten minute job...should be..
