Cleaning Engine Internal parts.

(1/2) > >>

Man Of Kent:
Afternoon all,

I have been given quite a few boxes of 400/4 engine parts, the chap had stripped down about 3 engines. A lot of the parts has got slight surface rust. My question is what is the best method in cleaning them up, I am cautious in using abrasives as being machined engine parts. My thought was too soak them in diesel then use a old tooth brush, degrease them to wash off the diesel. Then give the a light spray of oil and bag up in poly bags.

I would really like to know what you experts suggest.

Cheers Dave

Laverda Dave:
You can clean the parts in an ultrasonic bath with a suitable cleaning solution. Look at the Allendale Ultrasonic site (both on the Web and on ebay). They send the cleaning solution P&p free.
Personally I wouldn't re-use roller bearings if they have any rust on them.

Rob62:
Thats more than slight surface rust.....  :o . Use a paperweights only, unless you are absolutely desperate for the spares.

Nurse Julie:
I have seen a lot, lot worse but unless they are very rare, totally unobtainable parts, which they aren't, I wouldn't even bother. Surface / flash rust is ok to clean up but not rust that deep, the parts won't function correctly by the time you chisel off the rust.

Man Of Kent:
I think the pictures makes the rust look worst than it is, but is diesel ok to use or should I be using other chemicals?  :-\
