Rocker arm studs that have damaged threads or are loose should be replaced with oversize studs. Oversize studs are available in 0.003 and 0.013 inch and can be installed after properly reaming the holes as follows:
1. Remove stud using tool No. J-5802-01, or equivalent, Fig. 12, with a nut and flat washer placed over tool.

2. Ream hole to proper size using reamer tool No. J-5715, or equivalent, Fig. 13, for 0.003 inch oversize or reamer tool No. J-6036, or equivalent, for 0.013 inch oversize.

Do not install oversize stud without reaming hole since cylinder head damage could occur.

3. Apply axle lubricant to press fit area of stud and install using stud installer tool No. J-6880, or equivalent, Fig. 14.
