Just got it firing!
Hello,
I have a 1973 850 Eldorado LAPD that developed a knock in the right cylinder. I pulled the head and cylinder and found an excessive amount of play with the connecting rod on the big end, it will wiggle a visible amount in any direction and that ain't right. The left side seems to be fine.
I took the rod out and the bearings showed some scratches in the center but not much wear elsewhere. The bike has 88,000 miles on it. I do not know if someone has been in there previously.
It would appear I found the cause of the knock but not sure how to go about fixing it.
The crank journal doesn't appear to be damaged.
The bearing shell is stamped with 4473 and what looks like a "T" stamped over an "R" followed by 20 on one end and the other end looks like 000RA. Would these be original bearings?
Does the 20 reference 20 thousandths?
I guess I will have to measure the crank journal and bearings to see if I can go one size up to take up the play?
I will check the big end of the rod for roundness as soon as I can find my tools to do so.
Any advise for trying to make it all better short of tearing the whole engine apart and starting from scratch?
Thank you in advance!
