So I am doing the third service on my 700 and when removing the oil filter I noticed the washer/spacer is missing. I had the last service performed by the dealership. I am debating on wether or not to reinstall the oil filter without the shim. The shin prevents the spring from wearing into the rubber on the oil filter. It has been ran 1 service without it. I performed the 1st service on the machine and I know without a doubt it was there and reinstalled after the first service. What's your thoughts?
