MV Tooth Extraction, at Weare Rally - Transmission Problems

[lssah2025]

Phil, yes my transmission and transfer case were rebuilt and other gears were sourced. That was last year that they were replaced. But I definitely feel for you. Almost having a complete restoration and then finding out about the darn toofeshhesss royally sucked. Had to take off the floor plates and rebuild everything so I think yours is probably easier to replace then mine was. As for the Humber it is usually in rear wheel drive and then only the front are engaged for off road traction. So someone probably jammed it into awd without knowing what they were doing. Bob, that is what I was worried about having all the little teeth and fragments come into contact with the other gears and viola they all get screwed.

Lance, I'm with Bob. It looks like she was only part way in mesh, or had walked (its self) out of full mesh under load. Did you find anything else wrong at the time?

No everything else looked pretty good might have had some water in the case over the years had some pitting but all the bearings, seals and gaskets were replaced so she purrs now, the throw out bearing was also replaced so the entire drive line, electrical, mechanical and pretty much front to back was restored and replaced.

Hi All

Bob, I can't afford $105 per hour rate that's why I work so fast. Plus over the years I've worked out a couple of tricks for removing and installing the transmission. Biggest trick is this one a slide rail that goes between the windshield frame member to the back of the cab with a chain fall to lower and raise the transmission. (Picture shows it in use on the HUP) This same slide rail is also useful when installing the engine and transmission to support the rear of engine as you slide it in.

I'm starting my parts hunt today so Ill let you know how I make out.

The picture below is one that the guys in the club took of the process of pumping 3 quarts of lube back into the transmission, it takes 175 pumps per quart. Yes, I get kidded about the surplus Red Cross lab coat and rubber gloves.

Hi All

Progress report, I've got the gear box all apart and everything else looks good. On the parts hunt so far I have found a source of multiple 3rd gears NOS $60 each which could be put on to the old lower cluster it would require press the unit apart and pressing the new gear on. In talking with that source they may have an NOS transmission the whole thing $1200 they are checking to see if they still have it. From another source I found two used transmissions that look fair to good $125 each.

The NOS transmission if it is really available I think is my preference though I will buy a replacement gear for the original box anyway so that it is a complete ready to use unit. With three trucks all sharing the same box having a spare would mean I probably will never have transmission problems again.

Once as this thread has turned out to be more about the transmission and less about the Rally, once I can figure out how to do it I'll move the thread over to the Restoration heading.

Cheers Phil

Always good to have spares, one box for three, sounds like the way to go!!
