How to replace crank seals on Suzuki GT750?
The crank is the easy part, putting the transmission back together is the challenge. Make sure your carbs aren’t just out before you go ripping and into the engine. The carbs take some practice. If the engine isn’t leaking from everything I would concentrate on the carbs for a while. If you do take it apart plan on every seal, not just crank seals.
Where are the conrods on a Suzuki GT750?
The crank and conrods were sold as a single part by Suzuki then, so I’d think that may be the case with the GT750. PS Managed a work-around by fitting a brass bush to the middle small-end on the 380 to get it on the road.
What’s the compression on a Suzuki GT750?
Compression is 150 psi on 1 ans 2 and about 120 psi on 3. I rebuild the carbs and it fires up. I take it down the street under load and starts puking oil out of the transmission breather next to the oil pump. I’m pretty sure that it is bad seals on the crank. There’s not a whole lot of info on how to replace those inner seals.
When was the last crank rebuilt on a GT750?
The last crank I rebuilt was for my 1976 GT750A back in ’79 or thereabouts. It isn’t that hard as long as you have a stout press, assorted bearing splitters, v-blocks, dial indicators and such… There seems to be an abundance of places that would do a great job of rebuilding the crank.
