Ferrari F355 crank thrust bearings

Hi Everyone,
I am currently replacing the Aux timing pulley gear bearings the sump pan is removed and thought it a good time to replace the crank shaft thrust bearings as they are getting to the top limit of wear I have done this job before on other engines by removing the bearing cap and sliding the thrust bearings out before I start I was wondering if anyone has done this on the F355 ?? any advise or info would be greatly appreciated thanks
Fabio.

 

Hi Wade,
As I thought thank you for confirming this for me kind of you to take the time to help
Best wishes,
Fabio.

 

Hi ago car nut,
I don’t believe the thrust bearings are an issue on this crank set up it’s just general wear and tear the thrust bearings are ok on my car but getting to the top limit so it’s good practice to replace them while I have the sump pan off
Best wishes

That’s correct on this set up when the clutch is operated the slave cyl pushes the clutch/flywheel assembly towards the rear of the car
All the forces act on the large double row bearing in the pumpkin housing on a normal set up the forces push on the crankshaft ie pushing the crankshaft towards the front of the car the trust bearings take this force as merlin tech explains on the f355 the aux cam drive system uses 3 helical cut gears and under load the force pushes the crankshaft back to the rear onto the thrust bearing this force loads and unloads with engine rpm the thrust bearing is not under big stress but it will make it and other components life easier by using a top quality oil when I get time I will post some pictures of the thrust bearing and cap when I remove it.
