A couple /6 conversion Q's Options

[930cabman]

Wrapping up a couple patches in the battery/hell hole area, getting things ready to mount a new Maddog OEM style engine mount. It looks as though the main wiring harness will interfere with the new engine mount. Is it as simple as moving the harness towards the passenger side an inch or so?

Also, should I remove the /4 crossbar mounts? My gut says yes, get them out of the way

Is cutting a hole in the firewall required to access the fan belt?

TIA to all

1. Yes
2. definitely
3. I would not cut an original 6 chassis for fan belt access, but a conversion chassis, maybe. (IMG:style_emoticons/default/beerchug.gif)

One good reason to remove the 914-4 engines me mounts is because there is often rust behind the mounts, especially on the passenger side. I’ve removed them on my rusty tub and left them on the non rusty car. Works either way.

Thanks to all who replied. I have been researching this project for some time, but confirmation is always good.

Had a few hours this morning, wife out of town. The passenger side engine shelf was damaged from rust and prior impact so had been previously removed. Having access to the /4 engine mount made removal somewhat straightforward.

Drivers side engine shelf is in great condition, but will need a bit of selective demo to access the engine mount.

Is the only reason some guys cut out the firewall is for fan belt access? how did the factory allow for belt replacement/adjustment on the original /6 cars?

[mepstein]

Drop the motor or for some people with good dexterity, do it in place. I have seem pictures of a 90 degree bent box wrench to help with removing the fan nut

The belt can be changed in car but its not fun
You can not drive a 911 without a belt. Even a little bit will cook the engine

In my race car I have lost belts more than a few times
Would not want to do that replacement on the rush without the access

Adding my thoughts having used a Mad Dog mount on my conversion.

#1 yes. Everything fit fine

#2 I removed mine and thin put back a reinforcement piece of sheet metal. Some said it helped reinforce the area.



#3 the access to the fan area is very limited. My conversion does not have a access port. If I needed to replace the belt I would probably pull the engine. I would estimate a belt replacement for me in my garage at 5 hours. This would be pull engine, replace belt and reinstall.
I am starting another -6 conversion and plan on putting in a access panel.

I think the service cover is a must. Replacing the belt can be done without one but loosening the distritor bolt for timing its a must. Also, I left the engine mounts in....all the metal looked good, then mounted a plate over it ( This my new jack point) really work nice. Best, Mark

I vehemently disagree in the idea of cutting a hole in something called a "FIREWALL".

Having lived through an engine fire, it will not happen on my cars. The factory didn't put one in, so I am not either. The belt can be changed in the car. It is not easy, but it can be done. And it all else fails, roll the new belt on, then drive it home and drop the motor to replace it properly.

With how easy it is to drop the motor, I do it just to adjust the valves. So while it is out, I put a new fan belt on, even if it doesn't need it.

Looks like most people screw on a plate to cover the hole. If the vehicle catches on fire, exit the vehicle.

AT 70MPH?

[mlindner]

If a fire starts in a 914 four or six, at speed or stationary. Being that the engine is right behind you that rear window is going to go before anything regarding fire wall. And Clay I understand your concern, but a lot of 914 enthusiast do not have the tools or skill to pull engines that offten for service as you do. I greatly appreciate everything you bring to this forum Clay. Best, Mark

Lots of competent advice…..but would not do without in track car .

do not cut the firewall!!!!!! DO remove the four cylinder mounting pods CAREFULLY and immediately sell the right one on e bay for 450!!!

I gave mine away to another member here. I think Dion did the same.

Thanks again to all repliees (if that's a word) I have removed the passenger side /4 engine mount and it's in perfect condition, with a minimum of rusting underneath. Have yet to go after the drivers side, it's concealed by the engine shelf.

I will probably be opening up the firewall for fan belt access, as my gut and the advice of others tells me.

Also, it appears as though the brake compensator needs to be moved when using the Maddog OEM style mount.

This is not a bolt in conversion for sure, but I am hoping the result will be worth it. I have not driven or ridden in a 914/6, so this will be a surprise.

[mepstein]

The brake compensator was different in early vs late so some cars need modification. It will be worth it. A 914 with a six is a blast. (IMG:style_emoticons/default/driving.gif)

[r_towle]

can someone with a six show how hard it is to get in there to change the belt?

I was looking at the /4 the other day...and that is no walk in the park.
I recall this car is all about closing your eyes and doing the work purely based upon touch.

Can you fit all the required tools in to properly change a belt on a six...without ever having to drop the motor?
