Propshaft Tech Help
Prop Man - 7/7/09 at 10:17 AM

Hi Everyone.

Just to let you know if you have any problems with propshafts, universal joints, vibrations or anything else propshaft related, please do not hesitate to leave a massage on this thread or contact me directly.

I have been manufacturing propshafts for over 20 years at a reputable company and have a wealth of information and technical expertise behind me.

Thanks

Can you customise propshafts? I'll need one at some point and it would be nice to keep it in the family, so to speak.

Cheers
Colin

Yes

We can pretty much do anything you wish to a propshaft.

Thanks

can you do drifeshafts too?

Im going to need a prop and two driveshafts made up to custom lengths with different ends on them.


Prop Man - 7/7/09 at 11:17 AM

Hi

Yes drive shafts can also be manufactured, repaired and customized.

Thanks

I was just going to ask about driveshafts

You should look in to registering as a trader, I am sure you would get plenty of business.

ooh, just a quicj question. what is the minimum length of spline section that should go inside the type 9 box?
i put my engine in the car, measured the prop shaft, had it made up perfect, then when i fitted the engine 'properly' it sits about 1/4" firther forward. i think it will be fine, but just need reassuring

Could you please give us some more information on what to expect to pay for these jobs?

Everybody with a CEC will need

Propshaft shortened and balanced and possibly need new u joints.

How much would it be?


Prop Man - 7/7/09 at 12:07 PM

Hello

As standard we leave 25mm of spline showing from the gearbox seal.

It is ideal to have at least 70mm of spline engagement.

Thanks

As you all will know not every build is exactly the same.

And also prices for work change depending on what are you live in. Much the same as beer.

Alterations such as Shortening extending and balancing can be between £45 and £70 + VAT for most kit car shafts.

Universal joints are all individually priced on the size.

New Kit car shafts range from £95(standard) to £125 (heavy duty) + VAT in most cases.

These are guide prices and as i said they can vary depending on the area you live in and what the build spec is.

Ill be needing a prop made up to go from a BMW rubber gearbox coupling to a sierra diff flange. I have a BMW and sierra prop, but id be very interested in a price for a new prop, with new couplings, posted to Glasgow

awesome! thanks very much 1 last one then, since my prop is still in the car at the moment, do you happen to know how long the splined shaft part of the prop is in total? i've got about 1 1/4" showing at the minute. i have no idea how much is inside though


Prop Man - 7/7/09 at 03:01 PM

Depending on the parts used to manufacture the prop a reverse prop sleeve can be between 90mm and 105mm.

This is for splines on Type 9 Boxes

where abouts in the world are you??


stevegough - 7/7/09 at 08:36 PM

I was talking to a guy at North West Propshafts today - I need the two half-shafts shortening and balancing - he reckons it is quite an involved job, possibly using a technique called 'friction welding' - he said they send them to a subcontractor to carry this part out - price he quoted was £120+v each. He said that they can weld them normally, using a centre dowel to strengthen them, this would cost £45 each, but he has known one to break when done this way due to the high torque involved.

What is your view here?


Prop Man - 8/7/09 at 09:42 PM

The best way to join two shaft is by the process of Friction welding.

This is a special type of welding that uses the solid state welding process that creates heat through mechanical friction and force rather than current. It basically re forges the steel which makes it super strong.

Personally i would rather have my driveshafts done in this way than run the risk of a standard mig weld. 99 out of 100 will be ok but its the 1 that snaps and causes damage to something or someone.

Prices do vary on this. two driveshafts left our workshop yesterday to be fitted to a subaru these were priced at £145 + VAT each.

For friction welding you should expect to pay anywhere from £125 upwards depending on numerous factors.
