Putting in a WD 45 - any do's or don'ts? Do you put any lube on the 0 rings on the sleeve. if so what do you use? Getting things all clean before the drop in. Plan on some lube on cylinder walls, WD 40 or just engine oil? Thanks, Larry Miller ------------- I used to be young and stupid, now I am not young anymore. |

slide the liners into the holes and rotate to test fit PRIOR to adding the o-rings... should slide in easy if everything is CLEAN.. many say not to use oil / grease based product on the o-rings... I have used laundry soap in the past. ------------- Like them all, but love the "B"s. |

Larry, may not be right but have done several rebuilds on old AC's and I use liquid soap on the O-rings and motor oil on the sleeves. Soap is slick and lets o-ring go in without rolling and then gets sticky to stay in place and seal. Don't like penetrating oil to lubricate with. Good luck ------------- 1937 WC, 1948 G,1954 CA,1956 WD45, 1967 D17, 1937 M crawler, 1963 D-19, 1966 190XT, 1967 D-15, 1948 HG42 Cletrac, 1955 G456 Terra Trac, CAT 10 1928 and CAT 22 1938 |

| Vegetable oil or Crisco on the sleeve Orings and wipe the block bore with it too. |

Dad was an AC mechanic when series 4 D17s were new. He always used vegetable oil. Use motor oil to lubricate the liner bore |

Make sure you have an Allis Chalmers repair manual and follow it step by step. Make sure you install rods in the pistons correctly. Watch the video that Don Bradley made for installing seals and oil pan. If you have the engine out, replace the cam bearings. Make sure you have Plastigage to check rod bearing clearance (main bearings, too, if you have the crankshaft out).

Larry, I spent a lot of time cleaning and scraping the seat areas where the sleeves set. on the WD45 I did a year ago. I believe the number I was shooting for was .004 or .005 protrusion of the sleeve above the block. like others I used liquid dish soap on the o rings and engine oil inside the sleeves. Also soaked the piston ring assembly in some of the same fresh engine oil. Good luck with your rebuild!

| The messiest but best is can of oil to dip piston in clear up on wrist pin. Invert and drain excess,lightly clamp in soft jaw vise,install ring compressor and slide in pre lubed bore. One other thing not mentioned. When tightening clamp bolt on wrist pin, put a punch/hook bar or similar in vise and slide in wrist pin hole to hold while torking. Tightening small end by holding big end can tweak rod. Veggie oil is friendlier than dish soap. Try it the way Doc says. |

DONT USE SOAP! As others have suggested, veggie oil. I used soap, didn't get back to it for a period of time, every place my fingers touched rusted! ------------- I am still confident of this; I will see the goodness of the Lord in the land of the living.

| Detroit 92 series engine manual says use vegetable oil on liner orings. No mention of "anything else slick". |

Been a few days I believe I did use vegetable oil oil on the orings for the sleeves too. Good luck with your build!

Larry, when you do this test fit, make sure the counter-bores are clean and snug the sleeve down in place with a washer and a bolt on each side. Then you can check the stand out of the sleeves, Should be 3 to 4 thousandths of an inch above the deck. ------------- http://www.ae-ta.com" rel="nofollow - http://www.ae-ta.com Lena 1935 WC12xxx, Willie 1951 CA6xx Dad bought new, 1954WD45 PS, 1960 D17 NF |
