Re: Skip paper diff cover gasket for 518?

Hans, I'm sure you've already moved past this, so this is more for future reference for others reading. I've had great success with using Permatex Ultra Black silicone gasket maker on all covers and joints in the transmissions with the exception of the rear side cover (where the reverse idler gear i...

Re: Strongest Gearbox Possible

I recall reading (here?) that the S&R rings are from a van/truck -- Ford, maybe?? Of course, that leaves the pinion. Interesting. I understand a local indy shop uses pinion bearings from a Ford PU diff (not sure the model) rather than the standard SKF bearings... They may be the same bearings i...

Re: Strongest Gearbox Possible

The strange angle. Thats on the orginal S&R helical gearset. Its better to copy something that work. Take to much time and money to develop something new. Niklas I would generally agree, though the problem is that I don't have an S&R gearset to copy and I doubt I ever will. From that perspe...

Re: Strongest Gearbox Possible

What if the gearset were a 4 speed that uses the 5 speed primary case? If we could move 4th gear where 5th gear resides, that leaves room for 3 much wider gears in the main case which could then be easily synchronized without compromising the width of the gears. I like the way you think! Sorting ou...

Re: Strongest Gearbox Possible

The probelm whit the gearset Is the angle. Here in sweden they talked about Us, or GB angles. But in GB they don´t have the tools to make that angle. So they have to make a new tool for 2500 £. Niklas Could you elaborate a little please? Is there a problem with using a different angle? Or are you s...

Re: Strongest Gearbox Possible

Now...Luke and I discussed the possibility of making a custom gearset that would work off of a big splined shaft and have slip on gears. This was talking off hand without any measurements or calculations but it would simplify the build on the cluster gear. But see what your gear friend thinks...may...

Re: Strongest Gearbox Possible

It sounds to me like we're talking about two slightly different, but important, things. Seth's estimate was based on reproducing said gears which would require special tooling to match the original, while now we are talking about getting similar results, but using already manufactured shaping equip...

Re: Strongest Gearbox Possible

I'd be in for a reasonably priced (as in, not $10K) gearset. My requirements: Rally gear ratios - the S&R gearset ratio should work Fit into earlier boxes (a 4spd gearset would be just fine) Easy to source replacement parts (bearings etc.) Non-synchro would be preferred as to maximize gearbox s...

Re: Strongest Gearbox Possible

I think you could have a fairly easy shifting syncho-less box.. not sure though. I really think it depends on the # of dogs and the rest of the design. With such a small case to work with you need every mm of gear face (in my totally uneducated opinion) and synchros take up a lot of width... The ge...

Re: Strongest Gearbox Possible

I really doubt that a decent setup could be cobbled together for under $3000, look at motorsports gearsets for makes with way way more market share, VW, Honda, etc and a decent setup is still that much or more. Its possible that a 4 speed set with spur gears and dog engagement could be put together...

Re: Strongest Gearbox Possible

my .02..... if you are going to have a stout custom gearset made up go the straight cut gear route. Dump the synchros and go with wide straight cut gears in the ratios you want. The gear box will whine like crazy (every gear will sound like reverse) but they will be strong and a hell of a lot easie...

Re: Strongest Gearbox Possible

If you're looking for the seriousness of interest, I think most of us have already laid down a good amount of cash for stuff and finding a handful of people (10?) that will follow through shouldn't be terribly difficult. We already had a successful group buy of 10 or 12 Clutch-type LSDs imported fr...

Re: Strongest Gearbox Possible

I would have to know how the set is upgraded? What would be the base line gear set specs, based on pre 89" or post 89" layshaft/cluster, wider gears, etc. The 89 on layshaft gear with the inner bearing and seperate race is far superior to the earlier design with the bearing running direct...

Re: Strongest Gearbox Possible

That is pretty difficult to put a price tag on... Some more info will help: What else will we need to get the transmission built around these wider gears? I am probably dreaming, but $600-$1000 for the set would definitely get my interest. As I said, difficult to price. C 2X what Mezzanine mentione...
