 | | converting 8880 4 wheel drive to regular hubs —Lawrence Wilkes
|
| | | I haven't pulled my 8880 apart yet, but was thinking of building a 4x4 using the 8880 running gear together with the large power puller wheels. Then I realised that the wheel hubs on the 8880 have a 'special' connection to the axles. Is there an (...) (23 years ago, 5-Jun-01, to lugnet.technic)

| | | | | (...) Basically you can add regular hubs at the expense of steering which is fine for one axle but at least one axle needs to steer doesn't it! You probably don't remember but I was playing about with a related problem when I considered buying some (...) (23 years ago, 5-Jun-01, to lugnet.technic)

I haven't tried this myself, but here's a conversion courtesy of Jeff Boen: <URL:(URL) If it works the way it looks like, you may be able to retain all the functions of the 8880 suspension for normal wheels. The wheels will be offset more, (...) (23 years ago, 5-Jun-01, to lugnet.technic)

| | | | | | | Wow Fredrik, that could be just what I'm looking for too! So the question is, how much does it increase the offset and how much dish is there in a Power Puller wheel? Lawrence, if this works I'll have four wheels off you if you have any left. Psi (23 years ago, 5-Jun-01, to lugnet.technic)

It was very hard to steer the thing because of the twin rear axles. My solution was to make the (...) (23 years ago, 5-Jun-01, to lugnet.technic)
