advice/help on half shaft problem needed

[tr-pete]

Hi all... i have a tr4a american with the solid tr4 back axle, and my local garage who are brilliant cannot for love nor money push the shaft out of the hub to put the new seal in because it is leaking oil from the hub onto the shoes... they have a huge press and still cant do it ! any advice at all would be absolutely brilliant on where i can buy a complete half shaft with the hub attached or what you can do .... they have said they can cut the collar from the inside to remove the hub backwards down the shaft and put the seal in that way, but they dont know where you get new collars from and if you can fit them ... hope that makes sense !!

 

any help advice etc? many thanks pete

For heavens sake be sure your garage do not bend the drive flange in their enthusiasm to separate the items...or your pocket will start to empty. I have a spare TR4/4A half shaft but no spare flanges at present.

 

What you need to borrow is tool M86 that fits to the flange with all 4 wheel studs.

PS Solid axle 4A is to my mind the nicer of the breed.

 

PPS Do not over grease the hub bearing.

Had problems with leaking half shaft oil seals - doesn't do anything for your braking!

The half shaft/hub should pull out of the axle when the bolts through the axle collar are removed - see work shop manual.

the oil seals pull out but to get new ones back in straight I had to get a drift made - the problem is that the seals (thin metal and plastic) are an interference fit on the axle shaft and just tapping them in distorts them then they don't seal

Hope this contributes

thanks for the replies so far - a bit more info (as i learn myself!) according to the moss book it is a Girling axle - the garage doing it are a well reputed garage who do a huge amount of work for vosa on lorries etc - i know their press must be 30ton if not more, and they have used gas and cannot shift it at all....... according to the moss europe book, all the parts in there are listed, does that mean they are all available? Assuming the garage cannot in any way shift the hub out... does anyone have a complete axle or half shaft they want to sell...? many thanks - in anticipation i can get my beautiful car back on the road - it only failed its mot on insufficient brake on the rear and now it is stuck on the ramp with no hope of moving it !!

 

many thanks pete

Hi Pete,

if there is a price along side the Moss item in the cat then it will very probably be available from them.

 

If there is no price or NLS or NCA then it will not be available from Moss and probably anybody else as a new item.

 

You can look at the Moss USA cat as they sometimes list things that are not in Europe. TRF in the States often do their own thing.

 

Have you or the workshop looked at the TR4 Workshop Manual for dismatling the axle.?

 

Bigger presses do bigger damage!!!

Thank you to all who posted with helpful advice .i took the halfshaft to day from the garage to a specialists engineering works . And hay presto i hadn't even got home and they had lt apart. I think the garage had a good press when new but what year that was i dont know. It took 15 tons of pressure according to the specialist engineering works if that ever helps anyone else many thanks all pete

I think old TR hands have always said that a 20-ton press is required for this job, and it looks as if your specialist engineering workshop has shown this to be the case.
