I am rebuilding an XU9J4 to replace the one currentlyfitted to my BX16v. I got an engine from a wreck in the "Pick-A-Part"in Dapto. The speedo read 40k in the 1989 BX, and the engine looks to bethat vintage. Might have scored a good base t start with [IMG]file:///C:/Users/Michael/AppData/Local/Temp/msohtmlclip1/01/clip_image001.gif[/IMG].
So far I have stripped the engine completely and have theblock away to be cleaned, and the crank checked. I measured the crank bearingsurfaces "roughly" and they looked as new. A question. Is it goodpractice to replace the main bearing bolts? Are these bolts meant to be"difficult" to remove? I tried to get one out and it was verydifficult; so I stopped before damaging something.
I have a reconditioned head to go on and the"Z" hi comp pistons to go in. The liners appear in fine condition, nodiscernible lip and they measure as new.
Looking through past posts I noticed that Peter T statedthat he is no longer in favour of fitting the 26 tooth oil pump drive; I havegot one to fit, along with the "6Bar" spring. Should I fit the 26tooth or not??
I am fitting all new bearings and the usual replaceableparts – water pump, pulleys, timing belt, seals etc. Any good "hint"on the rebuild would be appreciated.
