I am rebuilding another P55M and doing the usual crankshaft modifications,ie fitting synthetic oil seals to the main bearings.To anyone doing the same a word of advice. The last one i did i replaced one of the main bearings[ single row ball]. Shop around, the first quote for a bearing was about $80 Australian. I eventually found one for $28.Down here in Albany I have found one for $24. BTW,the oil seals are $2 each. |

Peter - can you plse tell me the manufacturer's brg. number as well as the seal number so I can try to cross reference them here in the states.
I have ordered new snap rings for the gudgeon pins and the O-ring for the thermostat. If they work, I'll pass on the mfg. part number for them.
And should I consider replacing the seals in my P-55ME?
Thanks a bunch. |

Robert........the bearings are a single row ball bearing. Brand ...RHP [ UK manufacture],numberMJ 1-1/8-2r5
That is a one and one eigth of an inch IDxtwo inch OD or another ,same make RM59-2RS. THe latter is a sealed bearing ,just prise out the seals.
The oil seals are just a simple oil seal 1 1/8 IDx2inch OD up to 3/8'' wide.Before you assemble the bearings and crankshaft check the oilways . There is supposed to be a wad of gauze in them ,just check that it is clear |

Hello Peter and thanks for yet another bit of good advice and info.
Got my gudgeon pin snap rings yesterday and they are a direct replacement for the S-T one. US part is an IRR (Industrial Retaining Ring) # 3000-X56 or or Roto Circlip # HO-56ST. The O-ring is a Parker #2-224; buna N material.
Cheers |

My wife was breathing down my neck ,something about a recipe she wanted......so further to my previous posting!!
Glad to be of help Robert. The engine that i have been rebuilding has a lot of scale on the water jacket walls . I boiled the block in Caustic Soda for a day ,then neutralised it [ bi-carb of Soda.I then had it soaking in a Mollasses bath for about three weeks. The scale had softened somewhat but i still had to use a variety of chisels etc to remove it from the jacket walls. The use of a length of brake cable ,spayed out at the end and rotated in an electric drill works wonders |
