Re: Gemmer steering box

I was under the impression that some of the parts could be sourced from Lada steering boxes, or that the latter could be made to fit. Does anyone else know about this?

Re: Chain tensioner leaking

If I remember right, you assemble the tensioner on your bench and compress the spring before tightening it. Then, you bolt the pre-loaded tensioner on the head and release tension once it's on. Good tip on the counter-bolt, it was a Ferrari "upgrade" for the 246 at the time. Concerning the...

Re: Compression Test Results

I don't think he has bought the car...yet. If it was mine, I would continue driving it until something showed up indicating real engine work was needed. If it was going to be mine, I would factor in some money for the engine. These are great cars and the engine is very solid if properly looked after...

Re: Compression Test Results

Interesting numbers, how are you interpreting them? The lower losses on # 3 and #6 could be due to them being first in line to receive oil from the pump to the heads, although I don't see why this should affect the leak-down unless enough oil was getting into the cylinder to reduce leakage (leaky va...

Re: Compression Test Results

I would not worry too much about the actual values if they are the same and the milage is low. The values depend on the dead volume of the rubber hose and fitting wrt that of the cylinder volume and compression. You can correct for this if you know both. Evenly low compression on all cylinders could...

Re: Candle in the wind...

Mine improved considerably after fitting relays under the dash. The are operated by the poor, oxidised contacts in the steering stalk and power the lights with a fresh +12V sourced from the connector. I also wired them so that the high beams would not turn off the driving lights, giving really good ...

Re: 2400 Coupe engine rebuild

Hi, you are correct about the plugs being threaded on the ferrari crankshafts. I would assume that they are as well on these but, as you can see, they were inserted and ground flat against the counterweights. So, not much left to get a hex key in there to undo them. The place I bought mine to simply...

Re: 2400 Coupe engine rebuild

Hi, the crankshaft should be brought to the machine shop (along with the heads): They will drill out the plugs, clean the inside passages, and put in new plugs. There is a lot of crud that deposits in the recessed areas of the oil galleys. If it comes lose during the rebuild, it can end up on the be...

Re: removing brake master cylinder

Ditto, brake MC rebuild kit from superformance and removed/installed it on my back w/o the driver's seat and steering column. I did not drop the pedal box and it was a PITA for sure. Doable, no leaks since 10 y... The MC is solid, with little to go wrong except the perished rubber. If yours comes ou...

Re: Coupe Fuel Tank

Hi, I would try to contact Maurizio Zanella, he has a lot of spares for these cars. It will, however, add shipment from Italy.

Good luck,
