Datsun 240Z Restoration: Wheel Work
Happy Groundhog Day! A few minor updates from the Z restoration front:
- The Z’s right rear brake drum (pictured above) decided to seize up a few weeks ago. The wheel cylinder was evidently on its last legs, and after one too many applications of the parking brake, refused to unclamp the shoes from the inside of the brake drum. So, I can remove the drum from the hub (the typical challenge) just fine, but the shoes are still dug into the drum like a pair of rabid pit bulls. I’m going to try a few more tricks tonight. In related news, I hate drum brakes.
- In the wake of my tactical adjustment detailed in the last post, I’m assembling a spreadsheet of parts I need in order to try to start the engine. I’ve been using this site as a part number reference, with the understanding that not everything I need has to be new from Nissan. In particular, wear items like brake pads and shoes and other bits like brake and clutch master cylinders can be remanufactured items. It’s been a challenge compiling part numbers and prices, but I’m slogging my way through it.
- The removal of the wheels for brake service presented me with the opportunity to take some measurements. I was pleasantly surprised to find they’re wider than I thought they were, at 14 by 7 inches. The stock tire size is 195/70-14, but on a 7-inch-wide wheel I could go all the way up to a 225/60-14 without trouble, which is a lot of rubber for a 2350 lb car. I have a soft spot for vintage muscle car tires with raised white lettering, so what I would like to do is acquire a set of BF Goodrich Radial T/As (shown above). They would complement the look and feel of the car perfectly. But…we’ll see whether those are in the cards.
- ZTherapy received my carbs yesterday and, as expected, diagnosed the carb bodies as being too far gone to salvage. The company’s been under new management for the better part of 10 years now, after 5 or so with the original owner (who originally rebuilt my carbs), and has spent an inordinate amount of time repairing units damaged by the original owner’s remanufacturing process. The upshot for me is that reconditioning them will be more expensive than I had anticipated, but the new techniques used in adding the bearings to the throttle shafts (ZTherapy’s signature service) will last the life of the carbs; in other words, indefinitely.
