Do any of you guys out there have an extensive spares list that you would be willing to share? This would be like a check list of the spare parts that you might carry with you to the track. I'm not really talking about things like a set of race tires and spark plugs because I know about that. Do you guys think we would need to have with us a voltage regulator for example? Or do any of you racers carry a spare pilot bearing with you? What about rod bearings? THese are just a couple of examples that I'm throwing out there.

I do not carry much as you know. But I found that it is not easy to buy a rear outer wheel bearing at a NAPA/AutoZone, I always carry one (actually I carry whole sets of front and rear). Ignition Cap, rotor, brake bleeder screws, ... . I have to open the box in the garage to find what else in there. I guess I need to make a list now???

I have a list of what goes in my boxes...

I'll drop you an email. It's my packing list.

Ryogi, I want to be prepared so I don't have to go to Autozone for parts. I figure with twice the cars running we just double our chances of something breaking. We will have room now for spares but I don't really think we have a lot laying around after we put together our second car.

Vaughan, do you come to the track with a spare clutch or pilot bearing? I know we do after driving around for two hours looking for a clutch one time at night.

BTW Vaughan what you sent me yesterday was excellent! I expected that level of preparedness from an engineer and wasn't dissapointed.

I've started to put together a pretty comprehensive parts listing plus some of the places where you can purchase the items. These are items that we will most likely need to bring with us.

Vaughan, since you work for Bosch, could you score discounts on rebuilt starters and alts? If not than we need to get ours rebuilt locally so we can bring with us.

No, I don't bring a spare clutch or pilot bearing. I've never had a problem with mine, which would be why. Just put in new ones this rebuild; hopefully they'll be no more problematic than the previous ones (excepting the problems with the undersize flywheel).

As for starters and alternators. I did bring a spare alternator before, not sure it's still in there. It's a lot of dead weight. I would rather have a spare brush pack/voltage regulator, much more compact. As for starter - no, they don't hold up to the heat anyway, and you can push-start as needed.

What I've done for this year, in addition to trying different heat control methods, is to get a Bosch rebuilt starter from my local auto parts chain, Murray's. It was about $110. Of course, it's got a lifetime warranty.

We'll see how that works out, not to mention the header wrap. I've got my fingers crossed.

Technically there is a "deal" with Bosch parts, but their prices are lousy, and even with the discount you tend to get better prices through your local suppliers. That said, let's stay in touch; if you're having issues with starters still come Mid-O, I could it would seem pick up another from the local sources and bring with - if that seems like a good price to you.

I have wheel bearings already packed with grease. Some new, some perfectly good bearings that were pulled. I consider these 'track spares' for use when a bearing is going bad and we want to quickly get under way for a race. Just stick the bearing in without changing the (hopefully servicable) race. Just a mention: if you've service/replaced the rear bearing they are an unlikely failure point. Like-wise the front bearing IF you have the larger M471 spindle setup. OTOH, the std front bearing are TINY and I think I'll replace the outers at least every season just becaue. In addition to having a spare.

Same with clutches. Once the car is setup the clutch should be bullet proof.

Speaking of spares. I have a couple of axle/CV spares. Although, these also are pretty bullet proof assuming inspected and serviced (at our power levels). But, I recently discovered the outer race is NOT symetrical and they will bind if you reassemble backwards. The groove faces 'out'.

Yeah, I carry a spare driveshaft, used it once.

I must be screwing up my rear wheel assembly, as I have had to replace the rear bearings once or twice after they've gotten loose.

Loose? How mean loose?

I just looked closely again at that whole setup. As expected, the inner ball bearing does nothing for radial play by itself. I tried it. I have never been able to move the wheel axially after its all together, but the differenct thickness snaprings do control that. And every car I have put togther has needed thicker snaprings than were installed. 1 - I don't think it's very critical even though the factory manual addresses same, and 2 - I wonder if the factory even messed with it!?

Different thickness snaprings? Never realized there were such - maybe that's why I keep hurting the rear bearings? Too much slop from day 1?

Perhaps I need to look into it more closely...

I think a spare clutch cable setup is something to keep around. I've seen 914s that had the day end over this. Or at least look at the weaker points

Sway bars links as they can snap.

If you don't have new motor mounts, maybe one of each

Wheel bolts on the four bolt cars. Forget to torque one and you will loose it. extra lugs for the five bolt cars

Metal strap clamps large and small, can be used almost anywhere.

Spare fuel pump and relay, unless the one you have is new.

spare pan, gasket, oil and filters. seen cars go off road and pop a hole in the pan from a rock or debris.

spare oil lines if your using an external cooler, I've seen those fail.

and battery, make sure it is new and good

alternator as they can go at the weirdest times

[John Brown]

The inside ball or the outside roller?

Yeay. You know the big internal ring that goes in behind the ball bearing? They come in different thickness.
