Pinto crank bearings
I have a pinto 205 block out of a D reg Sierra GL (acknowledgements to Ned), want to know what type of big ends and mains it needs.
I dont know whether its been reground (TBH its in quite good condition, so either some sicko rebuit a sierra engine so it could be rampant once more,
or its just not done that many miles), but i believe theres two types of bearing available.
Is this true?? and if so, does anyone know which type fits this engine??
Cheers
Ed.
P.S. what size are the standard main and Big end journals supposed to be??

Ed,
just for your info, the sierra in question had 69,000 miles on the clock, but i suspect it'd been round once as the service book was stamped to
120,000! perhaps the engine has been rebuilt?! Anyone else's donor done this high a milage on original engine?
Ned.
beware, I've got yellow skin

I managed to find a engine machine shop who were very helpful, where are you.

I see nothing wrong - quote "sicko" - with someone having rebuilt a Sierra engine say in the early nineties, or am I missing a point?
Cranks in the 1800 (same crank as a 2 litre) always seem to last much better than in 2 litre, don't ask why, they just do. A well maintained
1800 will do 150k on a set of shells. A 2 litre, over 100k.
If your crank has been reground it will have a size stamped on back of shell ie 0.25mm. If no size then probably std. The mains will be nominally 57mm
at std and the big ends 52mm.
For rebuilding with a view to using in a Locost or similar where it may get a hard life use Lead/Copper shells. These used to be (incorrectly) refered
to as "Vandervell". Vandervell have had all sorts of problems in the last couple of years with distributors and are more difficult to
get. They are identical to the AE product.
AE shells are easy to get hold of and are top quality, the Lead/Copper ones you require are Mains: AEM91350 and Big Ends: AEB91349. Expect to pay
about £50 inc the vat for these (mains & b/ends together), the tin/alloy ones are a fair bit cheaper.
If you can't get them locally then ring me.
