Baldry1500 Posted September 12, 2012 Share Posted September 12, 2012 Does anyone know if there is one more than one type of input shaft used on spit 1500 gearboxes with overdrive?I've acquired a recon gbox and when i went to put the bell housing on i realised that the recon box has a aout an inch of wider shaft which catches on the bell housing and causes the shaft to lock up. I am planning on calling the supplier in the morning but wanted to know if anybody had any experience of this?Time is getting tight for the RBRR when i consider i also have the driveshaft UJ's and a new hood to fit. I could really have done without this delay as i was hoping to have fitted the new box tonight. Quote Link to comment Share on other sites More sharing options...
Nick Jones Posted September 12, 2012 Share Posted September 12, 2012 Yes.Earlier ones have a scroll type seal and later ones have a proper lip seal. The scroll/lip seal are located in the bellhousing and each needs a different size shaft. I can't remember which is larger, but a look in your bell-housing will show which type it wants.The actual seal carrier is separate from the bell-housing and could be tapped out and swapped for the matching one. I'd only suggest doing this if it gets you an upgrade to the lip seal.....Nick Quote Link to comment Share on other sites More sharing options...

Paudman Posted September 12, 2012 Share Posted September 12, 2012 Your bellhousing is scroll type, if you look into the seal you'll see a spiral cut into the metal. Later ones have the actual rubber / spring seal pushed into place and quite visible. I'll let those in the know advise on which of your two shafts is correct.

Baldry1500 Posted September 12, 2012 Author Share Posted September 12, 2012 No matter, no time to switch input shaft so have ordered the lip seal from canleys and will swap it at the weekend.Thanks for the help Quote Link to comment Share on other sites More sharing options...
Nick Jones Posted September 12, 2012 Share Posted September 12, 2012 You need the seal AND the seal carrier...... The good news is that the end result should be more oil-tight than what you had before :)Nick Quote Link to comment Share on other sites More sharing options...
Baldry1500 Posted September 16, 2012 Author Share Posted September 16, 2012 Argghhh. so new parts arrived on friday, just got around to fitting the new seal and carrrier. but the dowel holes on bellhousing and new new seal don't align by the smallest of margins. So.. do we think a duff part or is the dowel not critical? i'm guessing the former. any suggestions? Quote Link to comment Share on other sites More sharing options...
Nick Jones Posted September 16, 2012 Share Posted September 16, 2012 Your bellhousing looks to be alloy? Therefore must be an aftermarket one and I seem to remember hearing of this issue before with one of these. Does your original seal carrier have the dowel and fit properly? Have to say that an awful lot of repro parts seems to have quality issues.I'm not quite sure what the dowel is supposed to achieve. It will stop the seal housing rotating in the bell housing, but it's a fairly tight fit and should not be seeing much force likely to make it rotate anyway. Removing the dowel and fitting with loctite might be one option. Drilling a new dowel hole in the bell housing to suit it might be another. Can't remember if there is any specific orientation needed (oil drain hole in the seal carrier?).Should probably discuss with the parts supplier before doing anything drastic.Nick Quote Link to comment Share on other sites More sharing options...
Baldry1500 Posted September 18, 2012 Author Share Posted September 18, 2012 Cheers Nick,Bell housing is not alloy unfortunately. I can't see benefit of dowel either and agree about it's pressure. Loctite seems to be sensible half way house.Worrying about it on Thursday night as have kids to put down (not permenantly) singlehandly until then.
