P Marriott Posted February 16, 2010 Share Posted February 16, 2010 Hi all just after some advice on fitting new ring gear. I have already dropped the transmission, removed the clutch , flywheel and taken the old ring gear off. The question is, the new ring gear from Jeep parts is 1/8" thinner than the original and does not have a chamfer on the teeth. Are either of these points a reason not to fit the new ring gear???? Or should i flip over the old one and refit it??????? Should i also be thinking of replacing the rear bearing oil seal as it does weep oil or anything else in the area as i have it apart??? Is it also worth removing thje sump for a good clean out of the oil strainer? Anyway I await the words of wisdom from you all and look forward to getting covered in oil and grease!!

Bodger Baz Posted February 16, 2010 Share Posted February 16, 2010 how bad is your original ring gear? they are usually only worn in two places, i have often just taken them off and turned them 90 degrees on the flywheel so the starter can pick up on the good part of the ring gear. gets a second life out of the old girl. as for the rear crank seal you may as well change it as your in there anyway, no harm in doing that. same for sump can't do any harm, just usually means you find problems you didn't know had!!

robin craig Posted February 16, 2010 Share Posted February 16, 2010 As previously posted, you dont mention what problem your encountering. Sounds like you enjoy spending money! I would do as Bodger suggested and turn through 90 degrees and refit, doubt you will wear it out for many years. R Quote Link to comment Share on other sites More sharing options...
Adrian Barrell Posted February 17, 2010 Share Posted February 17, 2010 A 6 cylinder engine will wear the ring gear in three places so a 60 degree turn would be appropriate. Quote Link to comment Share on other sites More sharing options...
P Marriott Posted February 17, 2010 Author Share Posted February 17, 2010 Cheers for comments on ring gear. The problem was starting, starter didn't always engage in one position!! I rebuilt the starter last year with new bendix gear as that needed doing. Just thought with a bit of time on my hands i best get dirty and get the job done! Adrian is right it will wear in three places being a 6 cylinder and the wear is quite bad. I still wonder wether to just flip the ringear over or use the new one as supplied by Jeep parts even though it is 1/8" thinner. Quote Link to comment Share on other sites More sharing options...
