ivorybull Posted July 16, 2011 Report Share Posted July 16, 2011 Any tips on splitting a TY175 crankcase. Its being a bit difficult and the Haynes manual is not very helpful! Quote Link to comment Share on other sites More sharing options...
greychapel Posted July 16, 2011 Report Share Posted July 16, 2011 dont forget the screw behind the gearchange mechanism cover, the isolastic engine mount at the rear can be a sod too! Quote Link to comment Share on other sites More sharing options...

ausy300pro Posted July 17, 2011 Report Share Posted July 17, 2011 agree with greychapel re rear engine mount, mine was really hard to split and it was due to the rear engine mount being corroded, check that rear of crankcase is seperating.

ivorybull Posted July 18, 2011 Author Report Share Posted July 18, 2011 Do you use a crankcase splitting tool or use the Haynes Manual method of taping the crank shaft? I'm thinking of making up a tool to pull it apart rather than risking damage. Quote Link to comment Share on other sites More sharing options...
andy.t Posted July 18, 2011 Report Share Posted July 18, 2011 Do you use a crankcase splitting tool or use the Haynes Manual method of taping the crank shaft? I'm thinking of making up a tool to pull it apart rather than risking damage. I would try taping the cases with a soft mallet, could even try a little heat around the joint with a hot air gun, have the cases not parted at all?..is it completely stuck. I did make a tool for pushing them apart but the main reason they didn't want to split in my case was the screw behind the gear change mechanism which was covered in grease and didn't realize it was there, once this one was removed mine came apart.

ivorybull Posted July 18, 2011 Author Report Share Posted July 18, 2011 How did you hold the case in place when you tapped it. If you protect the crank shaft and tap the end it should push the cases apart but I was struggling to hold the front part of the case still when tapping the shaft to push them apart.

ivorybull Posted July 21, 2011 Author Report Share Posted July 21, 2011 Andy Finally got the crankcase split last night. You were right I had also missed the screw behind the gear shift mechanism which was covered in grease. The rear engine mount was also corroded and a real pain in the rear to get apart but as the case is going in the bin I didn't need to worry too much about keeping it pristine so managed to gently lever it apart. Thanks for the tips. Now for the swap over and rebuild Iain Quote Link to comment Share on other sites More sharing options...
