    Clutch / Brake Pedal Pivot Bushing Repair Idea

    I have had success on the rebuild of the clutch pedal pivot, and the brake pedal pivot by default as they use the same parts for the pivots. I used ZM 1519-16 Powdered Metal Bronze Sleeve Bearing Metrics from American Sleeve Bearing on line. I had to order 8 each to meet their minimum order amount. "P/M bronze stock items are manufactured of pressed copper and tin powders and impregnated with lubricating oil. They are intended by design to be self lubricating, maintenance free and low cost. Standard material specifications include: SAE 841, ASTMB 438 Grade 1 Type II, MIL-B-5687D Type 1 Grade 1, CuSn 6-6-3, Sint B 50 Standard impregnating oil conforms to SAE 30 specifications but product is also regularly supplied with special oils such as Mil-L-6085, Mil-L-17731." I used 12mm ID x 15mm stainless steel tubing to make new sleeves, 45mm long each. This tubing is not manufactured to a tight tolerance and I had to ream the tubing out to 12mm ID to fit the bolt. The OD of the tubing was also slightly to large to fit into the bearing by a couple of thousands. Chucked the tubes in my wood lathe and reduced the OD to fit into the sleeve bearing with some emery paper testing the fit as I went. The bronze sleeve bearings were an easy bench vise press into the pedal, the 16mm length is not a problem.

    Stamped numbers on steering shaft

    Mine has a Z J stamped on it, no other marks. It's from a 12/70 series 1.

    Clutch / Brake Pedal Pivot Bushing Repair Idea

    An update to this topic: I just spent the evening looking for bushings that will work without having to machine them. I have found some from asbbearingsonline.com that measure 15mm ID x 19mm OD and 16mm long. These will work with the 12mm x 15mm stainless tubing I have to replace the sleeve with. Should receive the bushings in a few days and will post results if they will work.

    Clutch / Brake Pedal Pivot Bushing Repair Idea

    After looking at how the pedal pivots closer I think I need to replicate the original design. The sleeve is pinched by the mounting bolt and the bushes provide the pivoting motion on the sleeve.

    Clutch / Brake Pedal Pivot Bushing Repair Idea

    I was not clear enough in my description of the problem. The hole for the pin that connects the pedal to the clutch master cylinder is worn only slightly. I'm talking about the bushings that the clutch pedal itself pivots on at its upper end. Where it is bolted into the pedal box. See the 240Z fiche section 97 Items number 22, 24 for the clutch pedal and item 3 and 5 for the brake pedal.
  8. My clutch pedal pivot is severely worn and needs replacement. The problem that I am having is that the bushings for the clutch and brake pedal are NLA from Nissan , or least I have not found any. My idea is to replace the metal bushings with a bushing machined out of Delrin or possibly Teflon . It would be a one piece bushing drilled to 12MM for the pivot bolt and the OD sized to be a press fit into the clutch pedal tube (about .75"). Any thoughts if this will work, would wear be a problem? Any input would be appreciated.

    71 rear control arm bushing frame clamp one

    That looks like rust where the bushing slips over the control arm. Some PB Blaster etc. in there will help, let it set upright so it will soak in. Grab the rubber with pliers and twist. I had one with Poly bushings that was a bear to get off because of the rust. Heat will also help if you get rid of the rubber first.

    Dashboard Repair Guide

    Move the spray side to side at a fast pace (more of a misting coat) and keep the spray can distance away from the surface as recommended on the can. I have used the SEM Texture Coat and the Polyvance texture coat, multiple light coats work best for me to get an even texture.

    Too rich for my blood

    I just wish you could trust the add copy. Most likely the person writing is is not that familiar with the car.

    Too rich for my blood

    I noticed a couple of things on the engine that have been changed/modded. Valve cover appears to be polished, Intake balance tube has items removed and it has some kind of throttle linkage modification, oh, and air pump is missing. Nice looking car, but for that money I would like everything to be stock and inplace.

    1971 HLS30-14938 "Lily" build

    I seem to recall at some point seeing that a washer (copper or bronze) was added to help reduce noise? or ??? Maybe that was in the differential though - memory not what it used to be.

    Introduction

    My car had one fiberglass and one steel headlight bucket when I got it, it's a early 71 240 that was built 12/70. It now has two steel ones after a lady backed into me in a gas station. The buckets were/are interchangeable across the years and are not a good way to date a car. A good web sight for some data on the 240's is zhome.com Look for the "Classic Z Car Register" Quite a few people have registered their cars and you can look for VIN #'s close to yours to get a build date.

    Introduction

    Does it have a build tag in the drivers side door frame? It will give you a build date if it's there. Number 149747 would place it somewhere in February of 1973 I believe. It was common on '73's to put the round top carburetors on them to help with vapor lock problems that the 73's had with the emission carbs known as flat tops. Also I have never heard that there is a difference in the headlight buckets for the 240's or 280's for that matter.
