How to remover TW roller pump?

[slim reaper]

Ah I did not realise the spline could be removed. My motor was knackered so had to replace complete unit. Fitting a extended spline is excellent advise as I am sure timberwolf did not bother due to cost.

 

I think we may have our wires crossed, the extended spline is not part of the motor.

A slide hammer didnt come close to extracting the one I did,I welded a one inch nut in the centre and the wound a bolt into it which jacked it out.

 

The first attempt with one run of weld around the nut broke away so it took several runs to hold the pressure of yanking it out.

To undo the three retaining bolts I used an impact driver.

 

The cost of the four new parts inc vat and postage was £118.22 but if you dont want to replace the opposite side parts, in the forground of the first pic, deduct £41.50.

 

I believe the newer TW has the extended roller from new?

 

 

You need a beast like this then A couple off good hard whacks and they are out. Its one I knocked up on the lathe out of a lump of 32mm bar a few years ago , bit heavy but highly effective.

Tis a beast to be sure! mine is only two feet long with a four pound weight. Is that an "O" ring you have holding the weight front sliding around?

The torx head retaining bolt are a pig to remove as is extracting the old drive spline which involves some heavy duty welding.

 

i just put a long thraded bolt in & wound it till the coller popped put ,

well I phoned orange plant for help when I couldn't get roller off and it worked a treat

 

just take the bolts out and use the button to make the rollers go back and forward, spine will come out easily

Interesting that, when I blow up the picture there looks like the outline of three bolt heads . what year/model is you TW?

Think Dan is talking about the roller body. That's the older design and you now need the new version.

Will the new version fit ok in place of the old unit??

Please tell me it's a straight swap!!
