New member. just signed up today. I have a 1995 White GT2055 with a 20 hp Vanguard V-twin and the engine needs to be rebuilt. The crankshaft is .005 smaller than spec. Anyone have any suggestions where i can get a used engine/short block/crankshaft & rods? From my many calls and google searches I understand B&G discontinued parts sometime ago. The short block is #499540 and the crank is #807778. Any advise would be greatly appreciated! Thanks.

Well I think I struck out ....... I went to my Briggs distributor and it shows the crank, but there is that chance that the crank is NLA ...... The short block is NLA so that's a scratch out on the list......

What you could do is get some plastic gauge and check the clearance like that ....... 5 thousands isn't that bad, but try the plastic gauge and see what that tells you.....

The closest HP in a new engine is gonna be a 18 HP in the Van Guard series..........

Maybe you could just re ring it and it might last another 10 years ????

Nobody has the crank are shortblock ..... If the short block would be available it would be close to a grand for it ......

Yeah, need to replace it with a good used Intek, easiest, or Kohler Command.

Yes Tink a repower is a choice or like I said earlier, use a plastic gauge on the crank and see how far it's out...... Do you agree that 5 thou is not a lot and a re ring job might be worthwhile to keep it going for a few years more ????

Those Van Guards are really tough engines and can take a lot of abuse ..... that's a 23 year old engine and has seen some work in it's time so far ........

A few bucks for rings and a rebuild gasket set would be the ideal way to go since he has the engine torn down already ....... I have seen worse on a few engines like that and they are still going strong ~!~!
