Re: Gutting a VW transmission

MartinRacing, Your initial post and question indicated that you have an IRS transaxle that you want to use for a mockup. The IRS transaxles for the beetle from about 1972 (or so) use a large (about 4 inch) thin round nut to hold the pinion bearing in place in the trans case. This does not have the ...

Re: Gutting a VW transmission

You may have a late bus irs which uses a large dia. nut that requires a special socket . A drift punch might work if you do not plan to reuse. If this is a late model bus it may not be valid for vee frame fab jig. This did not look like a bus to me. Side by side a type 2 versus type 1 looks signifi...

Re: Gutting a VW transmission

#12 in your "rebuild course" shows the location of the 4 pinion retainer bolts. Should be 15mm and if original will have locking tabs. Bolts need to be removed before the pinion can be "pushed" out. Hope this helps. Dietmar Any chance they do not all have those bolts? I sure did...

Re: Cranking Voltage Drop

That is a hard question. Among other things at work we build electronics that are used on diesel generators. We design the power supplies to ride through a momentary drop to 0 volts for about 20 milliseconds. Then a return to 6 volts, before slowly increasing to 24 volts. We design the power supply ...

Re: Cable Droop Limiter

Re: Cable Droop Limiter

I presume that the cable would be a commitment to a hard stop. I can get the cable made with threaded ends on both ends. I think I will be able to use rubber washers to provide a soft stop but would question whether the "packaging" of cable, clamps, pulleys, adjusters, etc would be advant...

Re: DOM tubing

For what it is worth. If the DOM is because of the GCR, I do not think that applies the the bottom frame rails. I think it applies to required roll bars and associiated bracing.

Cable Droop Limiter

I am considering using a cable as a droop limiter. The cable will go wheel to wheel over a center pulley or pivot point. Any opinions on why to do this or not to do this? I am considering it for packaging reason.

Re: 1970 Lynx vee

Thanks for the input. So how are all of your motors held it? When I bought mine it only had the four bolts in the bell housing holding it in, and they were very loose. It makes me uncomfortable thinking that only four little bolts hold the whole motor and transmission in. I am glad to here that the...

Re: Cutting patterns in metal

I have a vertical bandsaw, but the problem with most of these is that the blade speed is set for wood so it's way to high for metal and you need a step-down gear to run a metal cutting blade. That is a concern. It looks like I would have to go higher end to get to have a slower speed How about a ba...
