A runout of 0.0005 inch (0.00254 mm) at the bearing flange could result in a 0.001 inch (0.025 mm) runout at the rotor friction surface. The brake rotor attaches to the hub of the vehicle. Some vehicles are particularly sensitive to rotor runout, so much so that as little as 0.0015 inches of runout can produce noticeable pedal pulsations. If rotor wobble exceeds OEM specs, reindexing it on the hub (if possible) may help reduce runout. Rotors don't tend to be the source of pulsing back thru the brake pedal. This must be measured with a dial indicator against the face of the rotor. Page 1 SERVICE MANUAL Challenger 550 & 750; Page 2 Foreword Brief introduction to the service and maintenance handbook for 550/750 Challenger UV This manual gives methods to check, maintain and repair the Cub Cadet 550 & 750 utility vehicles (UVs), and supplies some relevant techniques and performance data. Childs, in Mechanical Design (Third Edition), 2021 4.1 Introduction. Lateral runout is the side to side movement of the brake rotor as it rotates. Sorry for bustin' em. Generally speaking hub runout should be .001 or less. GM's typical limit on disk runout is 0.005"which is measured at the largest diameter, so 0.1 mm (0.004" in real numbers) seems high for the much smaller diameter hub. Set the dial to zero and turn the rotor. 4. Total run out controls the entire surface simultaneously hence it controls cumulative variations in circularity, coaxiality, straightness, taper, angularity, and profile of a surface. The maximum TIR must not exceed the following specifications. This is the amount of hub runout. Note the difference between the lowest number and highest number obtained. 0.020 inch (0.508 mm).d. Solutions for Chapter 29 Problem 14RQ: A typical maximum rotor thickness variation specification required by an OEM would likely be:a. 1,607. Brake rotor thickness variation MUST be checked BEFORE checking for assembled lateral runout (LRO). Solid flat sections with maximum dimensions of 800 by 100 mm (width by height) and flat hollow sections with a maximum size of 800 by 60 mm can be produced from the Fig. When this gets excessive, pad and rotor wear will result.

Here we have less than 0.001 of runout which is good. The latest OEM service specifications typically say If runout is 0.2 mm (0.008") the result is equivalent to loss of a 1/2 oz weight which is noticeable. Typical manufacturing tolerance is 0.004 inches, discard at 0.01 inch run-out. Typical maximum rotor runout specifications are: 0.0003 to 0.0005 in. If the bearing flange has a runout, that runout will be magnified at the rotor friction surface. The manufacturing tolerances for rotor runout on most new rotors average about 0.001 inches or less, with a maximum upper limit of 0.004 inches. P.R.N. 8) Typical maximum rotor runout specifications are _____. Ending Point The ending point is the last point the operator wants a report on. 0.003 to 0.005 inches. Tighten down the rotor with the correct conical washers to the recommended lugnut specification. That amount of runout sounds reasonable. Modifications for Maximum Performance; O-200 Crankshafts; O-200 GPU crankshafts etc. CR Seals Step 2: Its important to measure the furthest point as this will show the maximum runout. Generally speaking hub runout should be .001 or less. If runout exceeds specifications, the rotor must be turned or replaced. (0.008 to 0.013 mm) b. FWIW (maybe not much), I always lubricated the surfaces and guides/pins with a LITTLE Never-Seize prior to reassembly. But it is what is is. A runout of 0.0005 inch (0.00254 mm) at the bearing flange could result in a 0.001 inch (0.025 mm) runout at the rotor friction surface. Outside the running surface, the run-out is approx. See Photo 2. Measure clearance between outer feed rotor and pump body with a feeler gauge. Runout in the hub and a new rotor can stack up to cause lateral runout that is beyond the specifications. The maximum allowable runout at the rotor friction surface is 0.002 inch (0.050 mm) as stated by most manufacturers. Prep, tools, taking a reading and set-up shown.
