I'm looking for a comprehensive checklist of service items for tracked cars. Oil, tranny and other fluid changes are straight forward enough. I'm looking more for the common wear or preventative maintenance items.
- Valves (valve jobs, checking retainers, etc)
- CV joints, bearings, hubs, etc.
- Clutch disc (replace once a year or every other year or just drive it until it fails?)
- Bushings
- ???

I've searched here and elsewhere and haven't come up with anything.

 

great thread. Interested as well.

I would guesstimate:
Hubs/bearings (change them at the same time) once a season
Check valves once a season, or any overrev
Diff fluid twice a season or more if you have a Kazz
Brake fluid every other race
Oil every three races

 

Ensure your spark plugs are properly torqued before each event!

 

That's an interesting one. Is there a story behind that suggestion?

I'm thinking change plugs at least once a season as well. Is that often enough or too often?

 

Make sure your oil filter is sufficiently torqued before each event. Yes, there is a story behind that one and the char marks all over my engine bay tell the tale

 

weld the upper A Arms

 

Many of the more commonly-observed failures can't really be prevented with prior maintenance (short of pre-emptive replacement). Some general issues, with prevention/remedy notes:

-Valve retainers (look for cracks periodically, replace as needed)
-Oil jet bolts (one-time update, '00-'02 only)
-Front upper A-arm brackets (one-time update with seam welds)
-Front lower A-arm bushings (check for damage, replace as needed)
-Ring&pinion (proper fluid with frequent changes; possibly remove rear swaybar)
-Fluid-filled diff mounts (check for leaks)
-Synchros (proper fluid with frequent changes)
-Clutch assy (flush fluid, replace disk/PP/TOB as needed)
-Inner CVs (swap cups side to side, use higher-temp grease)
-Outer CVs (replace as needed)
-Wheel studs (replace hub as needed)
-Hub bearings (replace as needed)
-Catalyst (replace as needed)
-Brake calipers (rebuild as needed)
-Brake rotors/pads/fluid (replace as needed)
-Wheels (check balance, discard or repair as needed)

And yes, obviously, spark plugs, oil filters, lug nuts, drain/fill bolts, etc. should all be torqued properly.

 

Great thread!!!!

Lug nuts have gotten me and JFO....doh!

 

Appreciate the quick and excellent input. The tough ones for me are the "as needed." My challenge is I have no idea how to tell when they're needed.

I realize in many cases there are no symptoms. Is there any info on mean time to failure (MTF)? I was talking with some of the Porsche mechanics at a recent event and they mentioned Porsche publishes MTF data on most every racing part.

I'd like to ultimately take all the input from the thread and update the first post with a summary by category.

 

forgot to mention HOOD PINS!!!!! hahaha... that one has gotten many hoods (including mine)....
