RealClassic MV AGUSTA 175 REBUILD
The 175 MV is an interesting, compact engine, although I will admit that it'snot the prettiest due to the rather boring parallel finning on the barrel. Certainly the CS cylinder head adds appeal to the sports models. The raised MV Agusta logo on the casings confirms that this is a CST; on the later models the logo is inset into the casings. As with many Italian bikes of this period, the engine is a stressed member of the frame and forms an integral part of it.
PART FOUR
Before taking the motor to pieces, I check to see if it has all the gears. It does – nearly – but there's something not quite right. The engine turns over: always a good sign. But it has no oil in it: not a good sign, but at least there's no water inside. On removing the cylinder head cover, all seems well except the camchain is very worn.the adjustment is at – no, beyond – the limit. The chain has started rubbing on the cylinder tunnel at the opposite side of the tensioner. There's no speedo fitted so I've no idea how many miles the engine had run when this damage occurred. I think this is a well-known issue on this model. The chain tensioner is a non-sprung type with a hardened guide, and has limited travel adjusted from the opposite side of the engine. This set-up gets its oil from the overflow to the rockers, a spray coming from the ceiling of the rocker cover which has a pressure oil feed to it.
