Primary chain wear 550 K1

<< < (2/4) > >>

McCabe-Thiele (Ted):
According to my records my rotor puller came from DS in Sept 2022 it cost £8.67 back then inc VAT.

Part Number is 079332160000 still listed now £9.58 incl VAT.

Murf:
Thanks  for help.

I will get everything ordered up, damaged my ankle yesterday so ordering stuff is about all I can do at the moment. 

So far Working on the bike would lead me to think it has not received the best maintenance in its life so it will be interesting to see what the shell bearings and crank journals look like.  Everything else has been knackered so not that hopeful. From what I have seen I get the impression that in many cases these engines are in need of serious maintenance eg top end rebuild by 30000 miles.  Type of use and maintenance will of course affect this, I guess bikes get an ever diminishing level of maintenance as they get older and less desirable, eventually being abandoned in a damp shed for 20 years. 😄

DomP:
I wouldn't be surprised if its not as bad as you think internally, my 550 had been poorly maintained and had the top end put back together with copious amounts of red gasket sealer as well as some numpty having put springs between the rockers on the tappets.  Thankfully everything measured up within spec with plastigauge and no damage to the rockers or valves.

Both the primary and cam chain were pretty well worn though, primary rubber bushes were like rock too.

McCabe-Thiele (Ted):
Certainly standing unused for a few years might mean a rebore is needed due to corrosion. If well maintained and used regularly I would have thought they are more than cable of managing well  over 60k miles.

Also prolonged standing in old oil can lead to corrosion of various ball bearings at the "tide mark" inside. If you use your own labour a pretty substantial  engine rebuild can easily add up to the £800 plus mark.

DomP:
Oh yeah I forgot I did need a rebore but other than that and replacing bearings while I was in there it was all pretty good.
