    Motor upgrade to 1" Shaft - Torque Converter Question

    I'm upgrading a 8hp Robin motor to a HF VTwin 670cc motor, the shaft is now 1" instead of the Robins 3/4. It has a TAV30 torque converter on it now. Can I but just the Driver/Driven Clutch side of the TAV40 that is 1" and keep the reset of the torque converter the same?

    Speedway torque converter cover question

    Is there a piece that goes on the Tecumseh HS40 engine that allows you you connect the torque converter guard to the engine end? If so, can anyone describe it? I see how it attaches on the lower end to the engine mounting plate but not sure of how it hooks to the engine. Thanks

    Tav2 Torque Converter

    I ordered and received a Tav2 TC from EBay, and it's causing me more trouble than I expected. First, the bolts that came with the TC didn't fit my predator engine.

    How far up/down the drivers does your torque converter belt go?

    As the title says how far up/down does your belt go? I took mine for a run on Sunday and the belt only seems to go roughly 3/4 of its travel. But man I love its take off now. It'll do a wheel stand if it gets enough grip :laugh: But it only revs out to 3000 and doesn't use the full travel of...

    Comet Torque Converter

    Can someone tell me what series this is? I see the 20 P3. Does that mean it is a 20 series? It is symmetrical so I have to assume that it is a 20 or a 40 series. The driven is 7 3/8''(???) inch. The drive is for a 3/4'' shaft. With the spring out it must have a reverse wound spring????? Is that...
