main bearings

A friend thinks he spun a main bearing in his 1976 GL1000,can anyone tell me the flat rate time for an R&R of the crankshaft in this model? Thanks Pete

Flat rate time is going to be meaningless for a vintage bike like that. FRT was designed for warranty repairs on newer models that have few modifications. By the time a bike is 34 years old the FRT is non-existant.

Most shops won't even take a job like that in.... maybe if there was a very sizable deposit put up first... but maybe not even then.
The bill will probably be more than the bike is worth..... and when a main bearing spins it could also take out the crank.

You'd probably be better off finding a decent used engine

Thanks for your reply Ray,I was just looking for a ballpark on the amount of time it would take,not withstanding seized fasteners and so on. Pete

Ok.... do you want the time that Honda would have given for a 1 or 2 year old model? or the time that it might take for an experienced tech to do the job on a 34 year old model?
or.... the time that it might take for someone that's never done this kind of job before?

In the early 70's I worked as a mechanic at the local Honda/Kawasaki dealership but I left to study heavy equipment repair before the GL series came on the market. I injured my shoulder on the job working for Caterpillar in 2001 and could not go back to the heavy stuff so now I take on the occassional small equipment job. If a current Honda shop tech would take 25 hours to do this job, it would probably take me 40 hours. I just want to give the owner a rough quote on the labour. We may find the crankshaft u/s after removal. As you mentioned before , a good used engine may be the best way to go.

Flat Rate for a 'new' GL1000 crankshaft R&R is 10.0 hrs.
Standard 'bump' is 50% in a shop
Given the fact that it's as old as it is, first time doing the job and semi-experienced tech I'd say 20.0 hrs. for billing.
Expect to spend more than that in actual time.... just the gasket scraping and proper surface prep can take 2-3 hours.

A quick story from one of the Honda Service Rep's on how Honda used to determine what flat rate times were established:

Honda would use a tech that had AAI training plus at least 1 year shop experience. They had him do one of the jobs in the Flat Rate Schedule (let's say replacing a valve in the cylinder head) 2 times using air tools. The first 2 times were un-timed so he would have a chance to get used to doing the job. The 3rd time was timed. That determined flat rate.

So, you can see how difficult it would be for a tech that hasn't ever done that specific job to beat or even match flat rate. The average or even above average tech will have to read the manual, collect required tools, perform the job and then clean and test ride the bike. The flat rate time is also supposed to include .1 hr for the warranty paperwork. Anyone that's done a job 3 times will be faster at it than doing it the first time. Again... these were done on new bikes.
