Pump oil to tensioners before startup after rebuild??

[Speed Buggy]

Has anyone hooked up a small pump to the tensioner oil supply line to "charge" the tensioners before initial startup after an engine rebuild? Would this even make sense? Is there any concern about the oil fed tensioners on startup? Cheers.

If you crank the engine with the starter (without ignition and fuel pump) a couple of times before initial start there will be oil in the tensioners. The initial spring load in them should be sufficient to keep the chains in place.

Thank you. That makes me feel better.

You can always Pre-Oil the motor before startup. Its what we do on every fresh motor.

In addition to the lube of internal parts during re-assembly, we also use a pressurized (30psi) Paint sprayer tank (5gal) with enough oil (8qts) to lube the entire motor before startup.

This is especially needed when it has been a while since the motor was built, or last run in the case of a used motor.

That sounds cool. Where do you connect that to? It's been 2 years, although the assembly started late last year.

Len,

Your above post caught my attention and curious to know its application. Could you elaborate how you inject/apply the oil into the a 911 engine for start-up? Do you account for the total oil in the engine and oil tank? Thanks.

This is what I posted back in 2010 related to pre-oiling......



"Whenever we pull a motor from long-term storage, we pre-oil it before starting it.

We have a 5 gal Pressurized Paint bucket that we put 6-7 quarts of oil in with a pressure regulator set at 40 psi.

Using some made-up fittings we run a coiled plastic hose from the tank over to the main oil galley and run the clean oil into the motor. With the plastic hose you can see the oil flow thru it.

By pulling one or two covers you can see when the engine is fully lubed.

Naturally if the motor is stiff, then you have to oil the cylinders w Marvel "Mystery Oil" or such before anything else.

This procedure has served us well for over 30 yrs. "


This was my response to a Pelican with an engine not run in 5 years. If I can find a photo I will post it.

Tony - lots of places to hook up for oiling. The idiot light switch would be one place, and the oil temp sensor would be another, and handier, place. Should be easy enough to rig up an M10x1.0 threaded fitting to hook your hose to.
