western Posted December 31, 2005 Share Posted December 31, 2005 Nothing in the LR RAVE info for locking a flywheel on a V8 engine, it says --- restrain crankshaft & remove the 6 bolts securing the flywheel. you could make a 'V' block to engage the ring gear teeth against a bell housing stud to hold the flywheel while undoing the bolts.

And there was me thinking LR would be efficient and have a tool Cheers for looking though V block Sounds like a good option, wouldn't be too difficult to make just with one corner of some rectangular bar or summit like that Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted December 31, 2005 Share Posted December 31, 2005 I use a tool I made up Simply its a lump of metal, with two holes drilled that bolt into the bellhousing holes, then I ground away one side leaving a "Tooth" which engages the flywheel Works a treat, and has taken loads of abuse from both me and to those its been lent to. Made from 3/4 inch thick Nige Quote Link to comment Share on other sites More sharing options...
minivin Posted December 31, 2005 Author Share Posted December 31, 2005 Made from 3/4 inch thick Nige Sounds about right definately a theme of engaging with the teeth developing here I've seen parts lists on some fly wheels showing the ring teeth portion being seperate to the flywheel, I take it it must be shrunk on to a high interference fit since it has to transmit the torque of the starter motor?

western Posted December 31, 2005 Share Posted December 31, 2005 Most ring gears are shrunk on by heating the ring up until it's red hot & dropping it over/around the flywheel & then letting it cool naturally, maybe quenching in a oil bat to re-temper/toughen it.

robhybrid Posted December 31, 2005 Share Posted December 31, 2005 I always used to have an old cylinder head valve that would sit in the teeth of the flywheel and then jam up against a suitably placed bolt screwed into a mounting hole. Went to do it again the other day and I couldnt find an old valve kicking about anywhere. I knew there was a reason for not tidying up and clearing things out.

jwriyadh Posted January 1, 2006 Share Posted January 1, 2006 3/8 bolt in the bell housing bolt hole and prybar in the ringgear teeth. If the sump is off use a wooden hammer shaft between a big end and the block. Observe the fitting instructions for ringgear, red-hot is TOO hot. jw Quote Link to comment Share on other sites More sharing options...

Jon White Posted January 3, 2006 Share Posted January 3, 2006 Decent rattle gun - no need to restrain the flywheel at all :-) Quote Link to comment Share on other sites More sharing options...
