Norton Commando Engine Rebuild. Part 31: Gearbox Internals Inspected
Вставка
- Опубліковано 18 жов 2024
- This is one of a series of videos covering the full dismantling, restoration and rebuild of a Norton Commando engine and gearbox. This particular video shows the internals of the gearbox - shafts, bearings, bushes, gears, selector forks etc. being checked for wear and damage before the gearbox is reassembled.
I'm about to tear into mine. Hopefully the case won't be cracked. Great video Chris
Thanks. Good luck. 👍
yep waiting for the assembly video before I assemble mine
Apologies, life is just currently so hectic! Away at a festival now and then on hols in Portugal next week. Hopefully start work mid August. 👍🤞
Fascinating content. Roll on the assembly episode. Who would design a gearbox case with such an obvious point of failure? No drip tray under the Honda lol.
😅
goodness me. i've had gearbox casings with far more damage that i've had welded, machined and put back into serviceable use with no concerns, admittedly they were made from unobtainium.
ps it you are going to scrap that case, i'll have it. and one last thing, that Matchless is gorgeous.
Mainshaft Circlip is part No 06.0752 and is shown in the clutch diagram in the parts list...for info
Yes, thanks, I've picked up on that. I couldn't work out why it wasn't in the parts book - but of course it is - in the clutch section! Doh! I have already fitted said circlip to the mainshaft. 👍
With regard to the sleeve gear on the MK3 with the circlips on the sleeve gear they used longer bushes, 1.2" rather than the 0.88" bushes on the earlier models I upgrade to these and locate them with Loctite, I have had no issues to date, looking at the engine number, it looks like this engine gearbox is from a fairly late MK2A, so is a cross over model, so could have been fitted with the later sleeve gear from new, my MK2A has some MK3 features. Isn't the circlip off the main shaft for locating the clutch, it is listed in the parts book inn the clutch section rather than the gearbox section.
That's great info, thanks. Yes, the circlip is indeed in the clutch section of the parts catalogue! I found it! - but I wasn't expecting it to be there, although as it is for the rear of the clutch to mount onto, as you say, it does make sense to put it there. 👍 As for the sleeve gear being fitted from new, I'm not so sure - someone has definitely been in there and fitted 3 bushes to it, so the gear itself may well have been replaced.
Whats your opinion about the one seal option on the main output bearing. My 70 Commando had the metal cover on one side so I ordered one from andover with the black one side seal cover. do you think it could starve the output shaft seal of oil or is there a good reason to use it. thanks good show.
Thanks for your comment - I'm not sure about the seal upgrade. When I get to it I'll check and post about it. 👍
