1974 MZ TS 250 assembling right hand case

Postby motorclocks » Thu Apr 23, 2020 10:18 am

i'm having trouble following Original MZ manual in two particular areas, one the right had case bearing and seal. On left side case no problem since it has a clip to bottom the bearing to and then seal went down flush with case wall. right side no clips and they ask that you use a special tool so as not to push seal into far where as it might rub crank, first that gives me the impression they are pushing it in from the outside which don't sound right. I want to put seal and bearing in easiest way so it is located in the right place. I know you have cup and shim has to be fitted finally. my thinking install seal same as left side flush with wall, install bearing from outside till it butts with seal so as not to push it to far and measure gap between cup with gasket on to fit shim.
My other concern is the right side gear bearings, they are showing them put on top of gears first instead of in right hand case. Then they talk about heating case to accommodate bearings, hows that work when your suppose to apply sealant on case, isn't heat a little much for that. I appreciate any help.

Following a biased and flawed moderator choice (someone posting aggressive personal attacks is rewarded, while my technical posts are removed - behind my back & without any justification!), I have withdrawn from this forum.

All.

As far as I think, Mike's main concern was that the documentation says not to insert the bearing too deep into the right hand side case. Other wise it will 'strike the crank'.

The problem is, I've never re-built a TS motor so I'm not sure what order things are said to be installed, and unfortunately tehre is no handy video tape like on the ETZ motors.. But it can't be that different though???

I'm not sure which bit goes in first myself. On my ETZ's I normally install the oil guide and circlip in the case, and then the bearing from within the crank side of the casing. Then let the bearing touch the oil guide/circlip. However I think the oil seals on the TS work differently? Or is it exactly the same???


Please someone with a TS come forward.. Puffs and I have no experience of TS.. :roll:

Hello

The oil seals of the 4 gear engines are inside, facing to the crankshaft.And there is no oil guide.Only oil seal and bearing.
For changing the oil seals the engine has to be dismanteld..
I would follow the intructions of the repair manual. If it is the original GDR manual. No Haynes or similar...
