trying to fit a type 9 gearbox to my herald and i'm a bit short of ideas for the 'box mounting. any suggestions please, with pics if possible...... thanks craig
finally got to measure it and a dolomite rear 1/2 between the u/j cups is 31", if you added a flange instead of the center bearing then it should give you 33 1/2" if that's close enough? craig
well i'm now sorted out, nearly. got a rebuilt 3.89 from GT6 M on here at a good price(he has others) thanks for everyones help,now to find the time to fit and trial..... looking forward to a quiet drive (well as quiet as a herald gets) craig
thanks nick, there are sharp edges on the c/w. I did wonder if a 3.63 might be pushing it and i'm not wanting to be putting a 1500 in,i'm quite happy with the 1300. will the 3.89 c/w replace my 4.11 c/w meaning I can use my original carrier etc? or will I have to get a diff that was 3.89 to start with? sorry for the q's but its an expensive mistake to make.... craig p.s if any one has a spare 3.89 diff for sale please????
thanks pete, stripped and rebuilt the diff with new bearings and seals paying particular care over the preload/ clearances etc but its still just as noisy...... looks like i'm needing a new crownwheel and pinion set (one side of the c/w teeth have a 'mottled' look to them), something is grinding itself to bits as there is metal chips in the oil when I split the case. currently its a 4.11 but would it be better with a 3.89 or even a 3.63 set? has an o/d box with a standard engine but I do a lot of motorway driving craig
just finally got my herald back on the road but now its got a noisy diff or gearbox,i cant decide which. basically there is a high pitched whine from it when either accelerating or cruising that gos completely when I let off the power. it does seem to be coming from the rear but I've just changed the diff with still the same noise. its a 3 rail o/d box and standard diff, could it be the box? if it is would it be worth converting to 5 speed? thanks craig
No the nosepiece was the one that came with the 'new' diff,i only remember this as I was going to change it over but couldn't get the old one off! Not that it was something that I considered/knew about when I was swapping bits about, just thought it quaint that a manufacturer put such things as packing pieces under the engine mounts and suchlike. Out of interest where is the 5/8 or 7/8 measurement taken from? My current pi has some vibrations to look into when I get time Craig
when i get there i'm going to try rover 200 style (because i have some) but you can get a shallower 'bucket ' seat from the likes of midland wheel center. craig
fairly sure the bolt pattern's different,thats for the 1 1/2(similar carbs on the dollys). i may have a sutible manifold for the 1 1/2 if you get stuck. craig
