    TMD40A - where to connect for a HW tank

    The hot coolant travels from the exhaust manifold, into the thermostat housing, up thru the thermostats when they open, to the HE and then back to the T housing and then to the circ pump. You are looking for an outlet which lies below the level of the thermostats, on the side or rear of the T...

    Challenge Refilling Coolant

    Your TAMD41 cooling system has a 20 liter capacity, 5.28 Gal., without a hot water heater circuit. As many have mentioned, idle the engine with the cap off of the expansion tank and the system will bleed itself. Sometimes loosening the banjo bolt at the top of the turbo bleed line helps get the...

    Volvo diesel question

    So, you’re really stretching the grey cells asking about TMD40a engines......but here goes... The TMD 40a was originally delivered with a rectangular plate type heat exchanger, and a plastic expansion bottle mounted directly to the rear of the HE on the side of the exhaust manifold. If memory...

    Stuck with removing flywheel from Yanmar 6LY

    No doubt the damper is recessed within the rim of the flywheel, very common construction technique and from the looks of it, plenty of corrosion holding the damper in place. The eight bolts on the outer rim are the ones which held the damper to the flywheel, and the inner bolts hold the damper...

    Rudder shaft? Help

    I have always called that part a sand shoe, or rudder skeg. Buck Algonquin, who calls them “skeg bars”, makes them available in a variety of lengths and widths made of bronze. Available from DeepBlueYachtSupply or others who handle Buck Algonquin.

    Interesting thread. I have an old Benmar Course Keeper 220 on my sailboat that I want to do the same thing with......use the drive motor coupled to a more recent AP controller. My unit also has an electric clutch, and I wonder if anyone knows whether the clutch functions on 12 volt, or uses...

    Power/Propulsion Problem - or Maybe Not?

    A couple of comments re: your engines and gear boxes..... The engine power curves that are published on the VP product bulletins always show BHP, (brake horsepower), that is the power that the engine can produce at a given RPM at FULL THROTTLE on an engine brake or dynamometer. This condition...

    Oil in Coolant. Volvo Tamd74 EDC

    Very unlikely that it’s a head gasket problem....both the oil passages and the coolant passages in the head gasket are O ringed. The oil would have to go out one O ring and in another.... Possible to be a cracked head, but also unlikely. Coolant might leak into the oil via a crack in the top of...

    Overheat problem Volvo Penta TAMD41B

    Well, this answer is a week or so late, but may come in handy for some other things (like replacing bellows) or perhaps helping someone else..... It’s easy to get access to the corroded water elbow that gave you problems without removing the drive from the boat, and here’s how: - drain the oil...

    Tamd40b ticking

    The first thing to do is determine what is causing the discrepancy between the oil pressure alarm/ light and the oil pressure gauge. My recollection on the TAMD 40 engines is that the gage pressure sender and the oil alarm switch were both mounted on a single "T" fitting which was screwed into...

    You can easily find new banjo fittings to attach to the lift pump and injection pump. The injection pump is made by Bosch and any good fuel injection shop can supply them. Available with female thread, flare, etc. Also available thru VP. This should expand the options at the engine end...
